The embodiment of the invention provides an oil well selection method for performing an energy-increasing throughput test, which comprises the following steps of:
the technical scheme provided by the embodiment of the invention has the beneficial effects that at least:

Next, the steps provided by the embodiments of the present invention will be explained.
And 101, determining a scoring standard according to the influence degree of the parameters influencing the oil well energy-increasing throughput test effect on the energy-increasing throughput test effect.
Optionally, step 101 includes: step 1011 and step 1012.
And 1011, determining parameters influencing the effect of the energy-increasing throughput test.
Parameters affecting the effect of the energizing throughput test are obtained by consulting the data and experimental experience in actual conditions.

Among the above parameters, the permeability, the number of beneficiary wells, the viscosity of crude oil, the saturation of oil, the formation deficit, the thickness of oil layer and the residual recoverable reserve have different values, and the effects on the effect of the throughput test are different.
In an alternative embodiment, when the residual recoverable reserve is in the first value range, the scoring criterion corresponding to the residual recoverable reserve content is a set threshold. And when the thickness of the oil layer is in the second value range, the scoring standard corresponding to the thickness of the oil layer is a set threshold value.

As an example, embodiments of the present invention select residual recoverable reserves of crude oil from an oil well, reservoir thickness, formation deficit, oil saturation, number of wells to benefit, crude oil viscosity, and permeability to determine scoring criteria. The scoring criteria are as follows:
the value range of the residual storable quantity is 3 multiplied by 10 4 Ton-19×10 4 Ton, or greater than 19×10 4 Ton of water; the range of the thickness of the oil layer is 2 meters to 10 meters, or more than 10 meters; the value range of stratum deficit is 0.5-5 square meters, or more than 5 square meters; the value range of stratum deficit is 10% -55%, or is more than 55%; the value range of the number of the beneficiary wells is 1-4, or more than 4; the range of crude oil viscosity is 50-1 millipascal seconds, or less than 1 millipascal seconds; the permeability has a value range of 100×10 -3 -0.6×10 -3 Millidarcy. The remaining recoverable reserves, reservoir thickness, formation deficit, oil saturation, number of recovery wells, crude oil viscosity, and permeability are scored at different locations within the respective value ranges. Setting the set thresholds of the residual recoverable reserves, the reservoir thickness, the formation deficit, the oil saturation, the number of beneficiary wells, the crude oil viscosity and the permeability of the parameters to be the same, namely the same scoring standard: score criteria of 0 score to 10 score.
And 102, scoring the parameters according to scoring criteria to obtain scoring results of each parameter.
As one example, the scoring criteria is set to 0 points-10 points. The scoring criteria corresponding to the parameters and scoring details of the parameters are shown in table 1:
TABLE 1
The meaning of the parameters referred to in table 1 will be described in detail below.
The residual recoverable reserves of an oil well refers to the difference between the recoverable reserves and the accumulated recoverable reserves after the oil field has been developed. The greater the remaining recoverable reserves, the greater the recovery potential of the well and, therefore, the better the performance of the well.
When the residual recoverable reserve of the oil well is greater than or equal to 3X 10 4 The remaining recoverable reserves of the well are good at tonnage. Thus, the remaining recoverable reserves are scored by 3X 10 4 Tons are the limit. When the residual recoverable reserve of the oil well is 3×10 4 Ton-19×10 4 Ton, or greater than 19 x 10 4 The residual recoverable reserves correspond to a scoring scale of 1 to 10 points in tonnage. When the residual recoverable reserves of the oil well are less than 1X 10 4 The remaining recoverable reserves corresponds to a score of 0 points in tons. I.e., the greater the remaining recoverable reserves of the well, the higher the score.
For example, when the remaining recoverable reserves of an oil well is 3X 10 4 The remaining recoverable reserves of the well corresponds to a score of 1 point at tonnage; when the residual recoverable reserve of the oil well is 5×10 4 The remaining recoverable reserves of the well have a score of 2 points at tonnage; when the residual recoverable reserve of the oil well is 7×10 4 The remaining recoverable reserves of the well corresponds to a score of 3 points at tonnage; when the residual recoverable reserve of the oil well is 9×10 4 The remaining recoverable reserves of the well corresponds to a score of 4 points at tonnage; when the residual recoverable reserve of the oil well is 11×10 4 The remaining recoverable reserves of the well corresponds to a score of 5 points at tonnage; when the residual recoverable reserve of the oil well is 13×10 4 The remaining recoverable reserves of the well corresponds to a score of 6 points at tonnage; when the residual recoverable reserve of the oil well is 15×10 4 The remaining recoverable reserves of the well corresponds to a score of 7 points at tonnage; when the residual recoverable reserve of the oil well is 17×10 4 The remaining recoverable reserves of the well corresponds to a score of 9 points at tonnage; when the residual recoverable reserve of the oil well is 19×10 4 The remaining recoverable reserves of the well have a score of 9 points at tonnage; when the residual recoverable reserves of the oil well are greater than 19×10 4 The remaining recoverable reserves of the well corresponds to a score of 10 points at tonnage.
It will be appreciated that where the remaining recoverable reserves are fractional numbers, the corresponding score may be selected accordingly around the score closest to the fractional number.
Reservoir thickness refers to the portion of the reservoir that has industrial oil production capacity. The oil well has a certain oil layer thickness, which indicates that the oil well has a certain oil storage capacity, a certain porosity and oil saturation, and crude oil can be extracted through various technological means on the premise of the conditions. Therefore, the thickness of the oil layer is taken as one of the influencing factors influencing the energy-increasing throughput test of the low permeability oil well. It is understood that the greater the reservoir thickness, the higher the reservoir oil content of the well, and the easier it is to recover crude oil after the energized huff and puff test.
The embodiment of the invention exemplifies an example, when the thickness of the oil layer is 2-10 m, or more than 10 m, the scoring standard corresponding to the thickness of the oil layer is 1-10 minutes. When the thickness of the oil layer is less than 1 meter, the scoring standard corresponding to the thickness of the oil layer is 0 minutes.
For example, when the thickness of the oil layer is 2 meters, the score corresponding to the thickness of the oil layer is 1 minute; when the thickness of the oil layer is 3 meters, the score corresponding to the thickness of the oil layer is 2 minutes; when the thickness of the oil layer is 4 meters, the score corresponding to the thickness of the oil layer is 3 minutes; when the thickness of the oil layer is 5 meters, the score corresponding to the thickness of the oil layer is 4 minutes; when the thickness of the oil layer is 6 meters, the corresponding score of the thickness of the oil layer is 5 minutes; when the thickness of the oil layer is 7 meters, the score corresponding to the thickness of the oil layer is 6 minutes; when the thickness of the oil layer is 8 meters, the score corresponding to the thickness of the oil layer is 7 minutes; when the thickness of the oil layer is 9 meters, the score corresponding to the thickness of the oil layer is 8 minutes; when the thickness of the oil layer is 10 meters, the score corresponding to the thickness of the oil layer is 9 minutes; when the thickness of the oil layer is greater than 10 meters, the score corresponding to the thickness of the oil layer is 10 minutes.
Formation deficit refers to: formation loss tends to cause formation pressure drop, the greater the pressure drop, the more energy that needs to be replenished, and the greater the potential of the well to replenish absorbed energy. The energy-increasing throughput is mainly used for solving the difficult problem that the injection of the low permeability reservoir cannot be carried out. Therefore, the stratum deficit is used as a factor influencing the low permeability oil well to carry out the energy increasing throughput test, and the situation that the oil increasing effect is not obvious after the energy increasing throughput test is carried out on the oil well with small stratum deficit or without deficit is avoided.
The embodiment of the invention provides an example, and when the oil layer deficit is 0.5-5 square meters or more than 5 square meters, the score corresponding to the oil layer deficit is 1-10 points. When the oil layer deficit is less than 0.5 square, the score corresponding to the oil layer deficit is 0 score.
For example, when the oil layer deficit is 0.5-1 square, the score corresponding to the oil layer deficit is 1 score; when the oil layer deficit is 1-1.5 square, the score corresponding to the oil layer deficit is 2 points; when the oil layer deficit is 1.5-2 square, the score corresponding to the oil layer deficit is 3 points; when the oil layer deficit is 2-2.5 square, the score corresponding to the oil layer deficit is 4 points; when the oil layer deficit is 2.5-3 square, the score corresponding to the oil layer deficit is 5 points; when the oil layer deficit is 3-3.5 square, the score corresponding to the oil layer deficit is 6 points; when the oil layer deficit is 3.5-4 square, the score corresponding to the oil layer deficit is 7 points; when the oil layer deficit is 4-4.5 square, the score corresponding to the oil layer deficit is 8 points; when the oil layer deficit is 4.5-5 square, the score corresponding to the oil layer deficit is 9 minutes; when the oil layer deficit is greater than 5 square meters, the score corresponding to the oil layer deficit is 10 points.
The oil saturation refers to the ratio of the oil volume in the effective pore space of the oil layer to the effective pore space of the rock, expressed as a percentage. The larger the oil saturation of the oil well, the larger the oil volume in the effective pore space of the oil layer, and the oil well is relatively easy to produce oil. Oil is also easier to produce when an enhanced throughput test is performed on it.
The embodiment of the invention provides an example, when the oil saturation is 10% -55%, or more than 55%, the scoring standard corresponding to the oil saturation is 1-10 minutes, and when the oil saturation is less than 10%, the scoring standard corresponding to the oil saturation is 0 minute.
Illustratively, when the oil saturation is less than 10%, the oil saturation corresponds to a score of 0; when the oil saturation is 10% -15%, the corresponding score of the oil saturation is 1 score; when the oil saturation is 15% -20%, the score corresponding to the oil saturation is 2 points; when the oil saturation is 20% -25%, the score corresponding to the oil saturation is 3 points; when the oil saturation is 25% -30%, the score corresponding to the oil saturation is 4 points; when the oil saturation is 30% -35%, the corresponding score of the oil saturation is 5 points; when the oil saturation is 35% -40%, the score corresponding to the oil saturation is 6 points; when the oil saturation is 40% -45%, the score corresponding to the oil saturation is 7 points; when the oil saturation is 45% -50%, the score corresponding to the oil saturation is 8 points; when the oil saturation is 50% -55%, the score corresponding to the oil saturation is 9 points; when the oil saturation is greater than 55%, the oil saturation corresponds to a score of 10 points.
The number of benefited wells refers to the number of wells that ultimately can be produced in performing the enhanced throughput test. The greater the number of benefit wells, the greater the efficiency of performing the energized throughput test.
The embodiment of the invention provides an example, when the number of the beneficiary wells is 1-4 or more than 4, the scoring standard corresponding to the number of the beneficiary wells is 1-10, and when the number of the beneficiary wells is 0, the scoring standard corresponding to the number of the beneficiary wells is 0.
For example, when the number of benefit wells is 0, the score corresponding to the benefit well is 0 score; when the number of the beneficiary wells is 1, the score corresponding to the number of the beneficiary wells is 1 score; when the number of the beneficiary wells is 2, the score corresponding to the number of the beneficiary wells is 3 points; when the number of the beneficiary wells is 3, the score corresponding to the number of the beneficiary wells is 5 points; when the number of the beneficiary wells is 4, the score corresponding to the number of the beneficiary wells is 7 points; when the number of benefit wells is greater than 4, the score corresponding to the number of benefit wells is 10 points.
The crude oil viscosity refers to the ratio of shear stress per unit area to the velocity gradient at any point in the crude oil. The higher the viscosity, the greater the viscosity, the more difficult the flow resistance, and the more difficult the crude oil is to be produced. By taking the viscosity of the crude oil as one of the parameters of the low-permeability oil well for the energy-increasing throughput test, the oil well with overlarge viscosity, poor fluidity and high exploitation difficulty is eliminated, and the efficiency of the low-permeability oil well for the energy-increasing throughput test and further oil production is improved.
The embodiment of the invention provides an example, when the viscosity of crude oil is 50 millipascal seconds to 1 millipascal seconds or less than 1 millipascal seconds, the corresponding scoring standard of the viscosity of the crude oil is 1 to 10 minutes, and when the viscosity of the crude oil is more than 50 millipascal seconds, the corresponding scoring standard of the viscosity of the crude oil is 0 minutes.
