Description
Technical field
The utility model belongs to the radial horizontal drilling technical field, is specifically related to a kind of radially horizontal well transfer.
Background technology
The oil field development of crossing very much of east China at present enters the middle and later periods, and in these oil fields, the oil-water well hole condition in many oil fields worsens.General production declining not only, even some oil-water well is because of output low scrapping too, and still the remaining oil of the oil well in exploitation exploitation difficulty is large, makes oilfield stable production volume increase arduous task.And, in undeveloped petroleum resources still, the resources occupation larger specific gravities such as Microreservoir, Margin reservoir, fault block oil reservoir, ultra-thin oil reservoir.If adopt the conventional drilling method to exploit these oil reservoirs, well yield is low, causes relative cost high, the economic benefit that is difficult to obtain.
In order to overcome the above problems, the radially horizontal well technology has appearred in pipe turning to.Turn to radially horizontal well can apply in Lao Jing and new well in pipe, be particularly useful for old filed volume increase and exploitation small oil field, marginal oil field etc.Compare and not only saved construction cost with the conventional drilling method, enlarged again the oil-gas Layer bare area simultaneously, make the individual well oil and gas production be improved.
the existing radial horizontal well direction converter that turns to the radially horizontal well technology in pipe that adopts, owing to need to completing in sleeve pipe by vertical turning to horizontal direction, the design of the track of steering gear inside turns to for high-pressure hose and conveying has a great impact, existing radial horizontal well direction converter is to adopt long straight tube to connect curve bend, by increasing when radius of curvature that the jet grooves circular arc radially curves reduces high-pressure hose or high pressure flexible tube by steering gear the resistance that is subject to, pyramidal structure is adopted in the curve bend outlet, but less for the space due in sleeve pipe, the frictional resistance that high-pressure hose is subject to while moving in steering gear is still very large, and high-pressure hose is easily blocked in the outlet of the taper curve bend of sudden contraction, be unfavorable for using.
The utility model content
Technical problem to be solved in the utility model is that the frictional resistance between a kind of energy minimizing and flexible pipe, the convenient radially horizontal well transfer that uses are provided.
Technical solution of the present utility model is, a kind of radially horizontal well transfer with following structure is provided, comprise and turn to body by what two parts connected and composed, the described track that is provided with for laying flexible pipe that turns in body, the importer of described track is to vertical with Way out, and described track is provided with several and is used for reducing the rolling member of the friction between flexible pipe and track.
Compared with prior art radially horizontal well transfer of the present utility model has the following advantages.Turn in body due to of the present utility model the track that is provided with for laying flexible pipe, and the importer of track can realize casing inner diameter turning to horizontal well to vertical with Way out.In addition, described track is provided with several rolling members, can will turn to the sliding friction between body and flexible pipe to be converted into rolling friction while moving in flexible pipe is turning to body, has reduced the frictional resistance that turns between body and flexible pipe.Also have, the described Way out of the track of body that turns to does not shrink yet, more convenient use.
As a kind of improvement of the present utility model, described track comprises successively the axial direct pipeline section that connects, inclined tube section, segmental arc and straight length radially.Improve the sleeve pipe inner orbit, reduce the bending of flexible pipe, turn to more smooth and easy.
As another kind of improvement the of the present utility model, the circular arc radian of described segmental arc is 90 °～130 °.Transition is more slow, reduces the impact of liquid to radially horizontal well transfer of the present utility model while turning to.
As of the present utility model a kind of preferred, described inclined tube section and to turn to the angle between the longitudinal direction of body be 10 °～30 °, angle of inclination is too large, easily cause bending excessive, while causing actual use, hydraulic shock power is too large, thereby affects the life and reliability of radially horizontal well transfer of the present utility model.Angle of inclination is too little, and outlet section is mild not and level and smooth, causes resistance to increase.
Preferred as another kind of the present utility model, the length of described axial direct pipeline section is 120～210mm.The length of axial direct pipeline section is oversize, can make the length of transfer of the present utility model long.The length of axial direct pipeline section is too short, turns to impact excessive, not mild.
Also have a kind of preferably as of the present utility model, the length of described inclined tube section is 100～175mm.Facilitate transition, transition is milder.
Also have a kind of preferably as of the present utility model, the diameter of described segmental arc is 120～210mm.Facilitate transition and turn to.
Also have a kind of preferably as of the present utility model, the length of described radially straight length is 10～30mm.Facilitate the use of horizontal well instrument, facilitate drilling well.
Also have a kind of improvement as of the present utility model, described rolling member is roller, corresponding described axial direct pipeline section, inclined tube section, segmental arc and radially straight length be provided with respectively a pair roller.Corresponding each section is equipped with a pair roller, can well reduce the frictional resistance that high-pressure hose is subject at each section.
