Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, this hair of Detailed description of the invention is now compareed
Bright specific embodiment, but protection scope of the present invention be not limited to it is as described below.
Solution cavity is the main Reservoir Body of fracture-pore reservoir, and the flow conductivity of solution cavity is high, pressure propagation speed is fast, leads to solution cavity
Internal pressure balance is fast；As the interface channel between solution cavity, flow conductivity is relatively weak in crack, controls the pressure between solution cavity
Dynamic balance process；It may be connected to by solution cavity between perturbed well and the seam_cavern type of observation well, it is also possible to it is connected to by crack, it is molten
The connectivity in hole is strong, fracture connectivity is weak, leads to inter well connectivity very different；Interference of the well under closing well state is observed to survey
Examination, what bottom pressure of monitoring itself reflected is the strata pressure variation for observing wellblock, i.e. the stratum energy variation of observation wellblock,
Therefore, this case proposes the Energy Analysis for High of fracture-pore reservoir interference test, the power of quantitative evaluation inter well connectivity.
A kind of Energy Analysis for High of fracture-pore reservoir interference test includes the following steps: selection observation well and one flatly
Perturbed well more than mouth or a bite；Slug injection and slug extraction operation are carried out to perturbed well；Pass through the pressure in test observation shaft bottom
Power variation, the power of quantitative evaluation inter well connectivity.
Before disturbed test excitement, the pressure for observing well is in steady state.Reflect the oil well of connection closing well,
The pressure recovery of entire fracture-cavity units has been approached stabilization, the injection or extraction of perturbed well will lead to observation well pressure rise or under
Drop；Rise as shown in Figure 1, generating pressure step after the injection of perturbed well slug, is generated under pressure step after perturbed well slug output
Drop.
Assuming that: the control reserve for observing well is constant, i.e., unit pressure drop quantum of output K is constant.Note of the perturbed well i in test phase
The amount of adopting Δ Np,iPart flows in or out observation well wellblock, with distribution coefficient XiDistribution of the perturbed well note amount of adopting to observation well is described
Ratio, the corresponding interference pressure difference of observation well are Δ Pi。
It is in closing well state before observation well and exciting well test, the interference pressure difference for observing well is that the note of perturbed well is adopted and drawn
The strata pressure variation risen.Observe the energy balance relations of well are as follows: the amount of adopting=elastic expansion amount is infused in wellblock, i.e.,
XiΔNp,i=K Δ Pi (1)
During disturbed test, since the flow differential pressure between observation well and perturbed well drives pressure difference smaller, it is only possible to
Starting is connected to preferable small range oil reservoir flowing, therefore, the unit pressure drop yield K that observation well is shown during disturbed test
(m3/ MPa) i.e. big pressure difference of the elastic rate far below normal production scenarios, the elastic rate that flows on a large scale, K value be not easy really
It is fixed, by distribution coefficient XiWith elastic rate K as a parameter group.
Define the interference strength between well: Xi/ K=Δ Pi/ΔNp,i, physical significance is the stream that perturbed well note adopts unit volume
The pressure change that body generates at observation well end, unit MPa/m3.Interference strength describes between well as a kind of quantitative indices
The power of connectivity, interference strength is higher, and connectivity is stronger.
The pressure of observation well is in downward trend on the whole.Exciting well section injection, as shown in Fig. 2, the pressure of observation well becomes
It is divided into 3 stages:
1) early period is interfered, pressure linear decline.It observes wellblock oil reservoir to flow to the producing well of connection, i.e. observation wellblock oil reservoir
There is leakage, total outflow flow is known as leakage flow.When periphery producing well keeps steady production, the leakage flow of well is observed
Approximation is stablized, and the pressure for observing well linearly declines at any time.
2) during interfering, pressure trend turnover.Perturbed well is injected using slug mode, postpones a period of time after injection
Observation well just responds.In perturbed well higher-pressure region to during observation well low-pressure area flowing supply, missed if increment is less than
Amount, the pressure decrease speed for observing well then reduce；If increment is greater than wastage, rise if observing the pressure of well.
3) later period is interfered, pressure trend turnover.When perturbed well wellblock and observation well wellblock pressure difference are reduced to certain journey
Degree, feeding if when pressure difference is less than starting pressure or inter-well pressure balance between well terminates, and observation well pressure drop is accelerated, the leakage in later period
Flow control pressure drop speed.
If the oil reservoir leakage flow for observing wellblock is qout, the pressure spot that disturbance response starts is (t1,P1), take interference early period
1 pressure spot (t0,P0).In t0~t1Period, wastage qout(t1-t0), the elastic quantum of output for observing well is-K (P1-
P0), wherein K is the unit pressure drop yield for observing well, m3/MPa。
Before perturbed well injection, the material balance relationship of wellblock is observed are as follows: wastage=elastic expansion amount, matter balance equation
Are as follows:
qout(t1-t0)=- K (P1-P0) (2)
Leakage flow indicates are as follows:
Perturbed well injection rate is Δ Np, interference useful effect phase starting point is (t1,P1), end point be (t2,P2), perturbed well
The material balance relationship of wellblock is observed after injection in the disturbance response phase are as follows: wastage-perturbed well part increment=elasticity is swollen
Bulk.
Wastage is qout(t2-t1), increment is part injection rate X Δ Np, X is the interference distribution coefficient of perturbed well,
Elastic expansion amount is-K (P2-P1), constitute matter balance equation:
qout(t2-t1)-X·ΔNp=-K (P2-P1) (4)
(3) are substituted into (4) to obtain:
Interference strength indicates are as follows:
It is indicated, is taken with pressure change slope
Interference strength (MPa/m3) indicate are as follows:
Wherein, m1Observation well pressure to interfere early period changes slope, m2It is oblique for the observation well pressure variation of disturbance response phase
Rate.
The pressure of observation well is in downward trend on the whole.Perturbed well slug extraction, as shown in figure 3, the pressure of observation well
Variation is divided into 3 stages:
1) early period is interfered, pressure linear decline.It observes wellblock oil reservoir to flow to the producing well of connection, i.e. observation wellblock oil reservoir
There is leakage, when periphery producing well keeps steady production, the leakage flow for observing well is also approximate stable, observes the pressure of well at any time
Between linearly decline.
2) during interfering, pressure trend turnover.Perturbed well slug formula output, output observe well after delay a period of time
There is pressure response.It observes well higher-pressure region to increase to perturbed well low-pressure area wastage, increases the pressure decrease speed of observation well.
3) later period is interfered, pressure trend turnover.When pressure difference reduces to a certain extent between perturbed well and the well of observation well
Flowing terminates between Shi Jing, and observation well pressure decline slows down, and the leakage flow in later period controls pressure drop speed.
When the conflicting mode of perturbed well is output, the quantum of output in the interference effect phase is Δ Np.Take 1 for interfering early period
Pressure spot (t0,P0), interference useful effect phase starting point is (t1,P1), end point be (t2,P2), interfere the pressure change of early period
Slope be m1, interfering the slope of the pressure change of validity period is m2。
Before interference occurs, the material balance relationship of well: wastage=elastic expansion amount, matter balance equation is observed are as follows:
qout(t1-t0)=- K (P1-P0) (9)
Leakage flow indicates are as follows:
After interference occurs, the material balance relationship of well: wastage+perturbed well part quantum of output=elastic expansion is observed
Amount, matter balance equation are as follows:
qout(t2-t1)+X·ΔNp=-K (P2-P1) (11)
Comprehensive (10), (12) formula, interference strength are as follows:
Wherein, Δ NpThe injection rate or produced quantity in stage, m are interfered for perturbed well1For interfere early period pressure change it is oblique
Rate, m2For the slope of the pressure change of interference validity period, t1、t2It is the beginning and ending time of interference effect phase.
Observation well well shut-in period is in pressure recovery ascent stage, reflects that the pressure of observation well is low, the pressure of peripheral offset well
Power is high, and peripheral wellblock flows into supply to observation wellblock, and the injection or extraction of perturbed well will lead to the pressure rate of rise of observation well
Variation.
Observation wellblock low pressure has inflow to feed before exciting, it is assumed that make-up flow qin, the pressure of observation well after excitement drives a well
Climbing speed reduces or pressure decline, is still analyzed with the pressure spot of front and back three that disturbance response occurs.If (t0,P0) be
Some pressure spot of disturbance response early period, (t1,P1) it is the pressure spot that interference starts, (t2,P2) pressed for some of disturbance response phase
The conflicting mode in force, perturbed well is the extraction that continuously drives a well, and the pressure change for observing well is shown as shown in Figure 4.
Before interference occurs, the material balance relationship of well: increment=Elastic penetration is observed
qin(t1-t0)=K (P1-P0) (14)
After interference occurs, the material balance relationship of well: perturbed well part output-increment=elastic expansion amount is observed,
Matter balance equation are as follows:
X·qp(t2-t1)-qin(t2-t1)=- K (P2-P1) (16)
It is expressed as slope form:
Wherein, qpThe average flow rate to drive a well for perturbed well.
Comprehensive (15), (17) formula obtain, interference strength are as follows:
Perturbed well drives a well the average flow rate q of phasepWith disturbance response phase t1~t2Between stage tire out yield Δ NpIt indicates, qp=
ΔNp/(t2-t1), then interference strength also referred to as produces the identical form of excitement with slug formula:
Assuming that the conflicting mode of perturbed well is to be continuously injected into, the pressure change for observing well is shown as shown in Figure 5.Using similar side
Formula analytical derivation, interference strength are represented by the identical form with the injection excitement of slug formula:
Therefore, the general formula that interference strength calculates under the conditions of observation well pressure is unstable are as follows:
The disturbance-observer amount of the interference strength of more perturbed wells, different perturbed wells indicates that perturbed well i's is dry with subscript i respectively
Disturb intensity are as follows:
Define perturbed well between opposite interference strength beThe size of opposite interference strength reflects
The connectivity between different wells pair is strong and weak out, provides quantizating index for the inter well connectivity evaluation in fracture-cavity units.
