Description

Linear cluster platform well deployment method and device

Technical Field

The invention relates to the technical field of oil and gas geological drilling, in particular to a method and a device for deploying a straight cluster platform well.

Background

In the exploration and development process of oil and gas resources, drilling a continuous shaft from the ground (wellhead) to a position (underground target point) of the underground oil and gas resources is the basis for realizing the development of the oil and gas resources. Earlier, the drilling technology influenced that only vertical wells could be drilled, i.e. the ground wellhead position was approximately in a vertical line with the target point of the subsurface target. With the development of directional drilling technology, even if the wellhead and the target point of the underground are not in a vertical line, the target can be realized by directional drilling by using a directional drilling tool, and the well type is called a directional well. The directional well drilling technology provides a means for oil and gas resource development in complex geographic environments such as shoal shallow sea, desert regions and the like, a plurality of wells or even hundreds of wells can be drilled on one operation well site or platform, the well mouths of the wells are not several meters apart, and well bores of the wells directionally drill towards different directions to complete the extension of a preset underground target, so that the development of the development direction cluster type platform well is realized. In order to save ground construction investment, reduce ground land acquisition, strengthen the connection of drilling procedures and improve the operation efficiency, the cluster platform well drilling mode is widely applied.

The cluster platform well deployment means that a certain method is adopted to position the corresponding relation between the sequence of each well mouth and an underground target. The good cluster platform well deployment scheme can realize the maximization of the space between wells, avoid the intersection of tracks and avoid the collision and obstacle-avoiding operation in the drilling process. Fig. 1 shows a cluster platform well deployment scheme, wherein the track crossing is caused by an unreasonable cluster platform well deployment scheme, that is, the straight well and the directional well track cross, for easy understanding, the diameter of the track crossing and the directional well are shown in fig. 2, and in order to avoid the track crossing of two wells, the drilling engineering must adopt collision and obstacle avoidance operation, which affects the operation efficiency, increases the operation cost, and has a great influence on the safety of later-stage well completion and oil production strings.

FIG. 5 is a first flow diagram illustrating a method of deploying a inline cluster platform well according to an embodiment of the present invention; as shown in fig. 5, the in-line cluster platform well deployment method may include the following:

step S100: and determining the plane coordinates of the center of the platform and the wellhead arrangement direction of the platform according to the plane coordinates of each target point.

Wherein, n underground oil and gas resource target points (x) of the cluster platform wells provided by the geological or oil reservoir department₁，y₁,z₁)、(x₂，y₂,z₂)…(x_i,y_i,z_i)…(x_n,y_n,z_n) Obtaining the plane coordinates (x) of each target point₁,y₁)、(x₂,y₂)…(x_i,y_i)…(x_n,y_n)。

Specifically, when the plane coordinates of the platform center are determined, the plane of a certain underground oil and gas resource target spot is preferentially selected as the platform center, if the preferred platform center does not meet the construction requirements on the ground conditions, or does not meet the unified planning and deployment requirements of oil companies, or the logistics support does not meet the requirements, the plane coordinates of the underground target spot meeting the requirements can be designated as the platform center coordinates, and a certain position can be designated as the platform center coordinates.

In addition, all well heads of the linear cluster platform well are arranged on a straight line, and the well heads are arranged along the straight line where a plurality of well heads are located in the direction.

Step S200: preliminarily arranging the wellheads according to the platform central plane coordinates, the wellhead arrangement direction of the platform, the preset wellhead spacing and the target spot number;

specifically, with the platform center plane coordinates as end points, arranging wellheads with the number equal to the target point number at intervals of the preset wellhead along the wellhead arrangement direction.

It should be noted that the platform center plane coordinate may correspond to any one of two well heads of the plurality of well heads arranged in a straight line.

In addition, the well mouth spacing p of the cluster platform wells is generally designed to be between 3 and 30m, more than 10m, and the p value can be specifically specified or designed according to the field ground conditions of the oil field.

Step S300: dividing the space around the wellhead into a plurality of target point position areas according to the wellhead arrangement direction, the wellhead position coordinates at two ends and a preset offset angle;

specifically, the space around the wellhead is divided into a plurality of target point position areas, so that the position distribution condition of each target point is quantified by using the target point position areas, and the subsequent deployment is facilitated.

Step S400: rearranging the well mouth according to the distribution condition of each target point in each target point position area;

specifically, the wellhead position is adjusted according to the position distribution condition of each target point, so that the wellhead position is accurately positioned.

Step S500: and determining the well mouth corresponding to each target point according to the well mouth after rearrangement and the distribution condition of each target point in the target point position area, thereby realizing the deployment of the linear cluster platform well.

Specifically, after the target point and the well mouth are defined, the target point and the well mouth are required to be in one-to-one correspondence, and the corresponding target point and the well mouth define the basic trend of one well.

By adopting the technical scheme, the well mouth is rearranged according to the distribution condition of each target point in each target point position area; the well mouth corresponding to each target point is determined according to the well mouth after rearrangement and the distribution condition of each target point in the target point position area, the straight well position can be selected as the well mouth position with the minimum influence on the track of the directional well in the rearrangement process, on the basis of realizing the rapid deployment of the cluster well platform, the collision and obstacle avoidance operation is reduced to the maximum extent, the operation efficiency is improved, the operation cost is reduced, and the safe running-in of later-stage well completion and oil production pipe columns is facilitated.

In an alternative embodiment, referring to fig. 6, step S100 may include the following:

step S110: and taking the coordinate of the target point with the minimum sum of the distances to other target points as the coordinate of the platform center plane.

Wherein, the sum of the distances from each target point to other target points is minimum, so that the horizontal displacement of each well on the platform is minimum, and the central coordinate (x) of the platform is selected_o,y_o) The following calculation method is adopted to calculate the time:

wherein n is the number of target targets, and i and j refer to any target targets respectively.

Step S120: and determining the wellhead arrangement direction of the platform based on a least square method according to the plane coordinates of each target point.

Specifically, the following formula is adopted for implementation:

represents the average of the abscissas of the target points,

and expressing the average value of the ordinate of each target point, wherein a and b define the linear arrangement direction of the wellhead of the cluster well platform well, namely the linear direction along y ═ ax + b.

In some cases, in order to unify the deployment direction of each platform in a block, the oilfield site may directly specify the deployment direction of the cluster well platform well, and at this time, the direction may be converted into a vertical well coordinate system, and the direction is recorded as a y ═ ax + b linear direction.

In an alternative embodiment, this step S300 may include the following:

a straight line (i.e. y is ax + b straight line direction, L1 in fig. 7) corresponding to the arrangement direction of the wellheads, two perpendicular lines (L2 and L3) perpendicular to the straight line at the positions of the wellheads at two ends, and four rays (L4-L7) which have preset offset angles with respect to the straight line at the positions of the wellheads at two ends and emit in the direction away from each wellhead, so that the space around the wellheads is divided into 7 target point position areas, i.e. an I area, a II area, a III area, an IV area, a V area, a VI area, and a VII area, wherein an acute angle area defined by two rays L4 and L5 at one end of the wellheads and acute angle areas L6 and L7 defined by two rays at the positions of the wellheads at the other end form a target point position area, i.e. the VII area, each ray forms a target point position area with the nearest perpendicular line, i.e. the I area, the III area, the IV area, and the VI area between, i.e., region II and region V.

Specifically, n is set₁N-1, calculating n well heads of the cluster well platform according to the well head spacing p of the cluster platform well to obtain the distribution of the n well heads of the cluster well platform (x)_o，y_o)、(x_o+n₁p₁，y_o+n₁p₂) Between the points, wherein,

p₁＝p*cos(arctan a)

p₂＝p*sin(arctan a)

at point (x)_o，y_o)、(x_o+n₁p₁，y_o+n₁p₂) A vertical line of the line y ═ ax + b and a line having an angle θ with the line y ═ ax + b were drawn, and a total of 7 lines were obtained.

The expression of 7 straight lines is shown in table 1:

TABLE 1 expression of 7 straight lines

The 7 straight lines can divide the plane space into 7 areas I, II, III, IV, V, VI and VII. Are respectively positioned right in front and right behind (VII, the north bias direction is assumed as the front), left (II), right (V), left front (III), left rear (I), right front (VI) and right rear (IV) of the cluster well platform.

According to the relation, all the underground oil and gas resource target points can be distributed in 7 areas, and as the geological reservoir underground oil and gas resource target points basically exceed 50 meters and are usually more than 100m, for a linear cluster platform well, the number of the underground target points distributed in each area is only 1-2, and the following table shows that:

the above table shows the situation that the distribution of the target points in the underground part of the area is low or even lacks the distribution of the target points in the underground part.

In an alternative embodiment, referring to fig. 8, this step S400 may include the following:

step S410: judging whether a target point exists in an acute angle area adjacent to the platform center plane coordinate;

if yes, go to step S420; otherwise, step S430 is performed.

Step S420: and moving all wellheads to an acute angle area adjacent to the platform center plane coordinate along the linear direction by the preset wellhead distance.

Step S430: the well head is not rearranged.

It should be noted that, if there is a target point in the acute angle region adjacent to the platform center plane coordinate, a well head close to the acute angle region among the plurality of well heads arranged in a straight line should be allocated to the target point in the acute angle region, so as to prevent a straight well from crossing a directional well trajectory corresponding to the target point in the acute angle region.

With particular reference to FIG. 7, n wellheads in the platform are labeled P1, P2, … Pn in that order, according to the spacing of the wellheads, wherein P1 is located in the southerly or westward direction in the platform, and specifically in geodetic coordinates, the P1 wellhead location x and y values are smaller than Pn.

for case ④, the wellhead position with platform center wellhead number P2 or Pn-1 is set to (x)₀，y₀) Position such that wellhead number P1 exclusively drills a subterranean target (x) of the region VII_Ⅶ2,y_Ⅶ2,z_Ⅶ2) Or the underground target point (x) of the special drilling area VII with the number Pn of the wellhead_Ⅶ1,y_Ⅶ1,z_Ⅶ1) (ii) a If P2 is set to (x)₀，y₀) Then P1 to Pn well head coordinates are sequentially (x)₀-p₁，y₀-p₂)、(x₀，y₀)、(x₀+p₁，y₀+p₂)、(x₀+2p₁，y₀+2p₂)…(x₀+(n-2)p₁，y₀+(n-2)p₂) (ii) a With Pn-1 set to (x)₀，y₀) Then P1 to Pn are respectively (x) at the wellhead coordinates₀-(n-2)p₁，y₀-(n-2)p₂)、…(x₀-2p₁，y₀-2p₂)、(x₀-p₁，y₀-p₂)、(x，y₀)、(x₀+p₁，y₀+p₂)。

In a further embodiment, this step S500 may comprise the following:

specifically, the well heads at any end of the linearly arranged well heads are vertical wells, and the rest of the well heads are distributed to the target points in an order-defining manner along the two sides of the straight line L1 and along the arrangement direction of the well heads.

For example, referring to FIG. 9, in the well heads p 1-p 9, p9 corresponds to the platform center and has the coordinate of (x)₀，y₀) And forming a vertical well at the same plane position as the target point T1, and according to the principle, allocating p8 to T2, allocating p7 to T6, allocating p6 to T3, allocating p5 to T7, allocating p4 to T4, allocating p3 to T8, allocating p2 to T5, and allocating p1 to T9.

Specifically, with continued reference to fig. 7, the underground target targets corresponding to the wellhead numbers may be sequentially determined from the direction P1 → Pn, at which point the wellhead numbers are sequentially deployed and designed according to the preferred sequence of the regions i/iv → ii/v → iii/vi; or determining the underground target points corresponding to the wellhead numbers from the direction Pn → P1, wherein the wellhead numbers are sequentially arranged and designed according to the preferred sequence of the areas III/VI → II/V → I/IV;

except for the wellhead sequence numbers occupied by the underground target targets of the region VII, the underground target targets corresponding to the rest wellhead sequence numbers are determined according to the following modes: if the well head serial numbers are determined from the direction P1 → Pn in turn, the well head serial numbers are alternated between I and IV, II and V, III and VI, i.e., (x)_Ⅰ1,y_Ⅰ1)→(x_Ⅳ1,y_Ⅳ1)→(x_Ⅰ2,y_Ⅰ2)→(x_Ⅳ2,y_Ⅳ2)→(x_Ⅱ1,y_Ⅱ1)→(x_Ⅲ1,y_Ⅲ1)→(x_Ⅵ1,y_Ⅵ1)→(x_Ⅲ2,y_Ⅲ2)→(x_Ⅵ2,y_Ⅵ2) The sequence of the target points is P1 → Pn (except the wellhead sequence number occupied by the underground target point of the region VII) to designate the corresponding underground target point, when the target point without underground oil and gas resources in a certain region is met, the target points can be directly continued, and the directional target points of two adjacent wells are prevented from being in a unified region.

For example, referring to FIG. 10, in the well heads p 1-p 9, p8 corresponds to the platform center and has the coordinate of (x)₀，y₀) Forming a straight well in the same plane position as the target point T1, T2 being the target point in the acute angle region adjacent to the platform center plane coordinates, paired with the end well head p9 closest thereto, and assigning the remaining well heads p 1-p 7 except for the end well head p9 and the well head p8 at the platform center plane coordinate position as follows:

p7 was assigned T3, p6 was assigned T6, p5 was assigned T4, p4 was assigned T7, p3 was assigned T5, p2 was assigned T8, and p1 was assigned T9.

Of course, in the example of fig. 9 and 10, the downward direction alternation may be started from the upper side of the straight line L1, and the upward direction alternation may be started from the lower side of the straight line L1, which will not be described again.
