[0002] At present, sand-producing oil reservoirs generally adopt early sand control to put them into production. However, there are problems such as blockage caused by the migration of free sand to the artificial sand control well wall, resulting in low production after sand control and poor production retention ability.

[0003] During production, uncemented free sand is transported with the filling sand injected during construction to the wall of the artificial sand-control well, causing blockage. This results in low production and poor retention capacity after sand control, and requires further unblocking and sand control, which increases cost investment.

[0004] In order to improve the production and production retention capacity after sand control, it is necessary to carry out sand removal and liquid production in the sand-producing oil wells in advance, and then take sand control measures after the free sand in the formation is removed. However, it is not clear when to carry out sand control, resulting in poor sand control effect. Summary of the invention

[0075] Figure 2 is a flow chart of a method for determining the duration of sand control provided by an embodiment of the present application. The method is applied to an electronic device, which is a terminal or a server. Figure 2 , the method comprises the following steps.

[0076] 201. The electronic device obtains the production of multiple first oil and gas wells within a first time period after sand control is performed. The multiple first oil and gas wells perform sand control at different times. The multiple first oil and gas wells perform sand control after a second time period after production, and different first oil and gas wells correspond to different second time periods.

[0077] 202. The electronic device determines a target oil and gas well from the multiple first oil and gas wells based on the production of the multiple first oil and gas wells, wherein the daily production of the target oil and gas well within the first time period is greater than a production threshold, and the rate of change of the production within the first time period is less than a rate of change threshold.

[0078] 203. The electronic device detects the liquid produced by the target oil and gas well to obtain the sand content in the liquid produced by the target oil and gas well within the first period of time.

[0079] 204. The electronic device determines the amount of sand and gravel discharged from the target oil and gas well within the second time period based on the sand content and the production of the target oil and gas well within the second time period corresponding to the target oil and gas well.

[0080] 205. The electronic device determines the amount of sand and gravel per unit oil layer thickness based on the amount of sand and gravel discharged and the oil layer thickness of the target oil and gas well.

[0081] 206. The electronic device responds to a time determination instruction for sand prevention measures for any oil and gas well, and determines a target second time duration corresponding to the any oil and gas well based on the liquid production intensity of the any oil and gas well, the amount of sand and gravel per unit oil layer thickness, and the sand content of the liquid produced by the any oil and gas well. The target second time duration is used to indicate the time duration for sand prevention measures for the any oil and gas well after production.

[0082] The embodiment of the present application analyzes the relevant data of the oil and gas wells that have been put into production, selects the oil and gas wells with relatively good production and production maintenance, and uses these oil and gas wells as references to determine the amount of sand and gravel per unit oil layer thickness, so that when the sand control opportunity of any oil and gas well needs to be analyzed later, the amount of sand and gravel per unit oil layer thickness, the sand content of the oil and gas well itself, and the liquid production intensity can be used to analyze the sand control opportunity suitable for the oil and gas well. Based on sufficient data and combined with the data of the oil and gas well itself, the sand control duration determined is more accurate and the sand control effect is better.

[0083] In some embodiments, the liquid produced by the target oil and gas well is detected to obtain the sand content in the liquid produced by the target oil and gas well within the first period of time, including:

[0084] Conduct core displacement experiments on the liquid produced by the target oil and gas well and obtain experimental results;

[0085] The sand content in the liquid produced by the target oil and gas well within the first period of time in the experimental results is extracted.

[0086] In some embodiments, the production threshold is determined based on daily production of a plurality of second oil and gas wells, the second oil and gas wells being oil and gas wells that are subjected to sand control before production.

[0087] In some embodiments, determining the amount of sand and gravel discharged from the target oil and gas well within the second time period based on the sand content and the production of the target oil and gas well within the second time period corresponding to the target oil and gas well includes:

[0088] The product of the sand content and the production of the target oil and gas well in the second time period corresponding to the target oil and gas well is obtained, and the product is used as the amount of sand and gravel discharged by the target oil and gas well in the second time period.

[0089] In some embodiments, the method of determining the amount of sand and gravel per unit oil layer thickness based on the amount of sand and gravel discharged and the oil layer thickness of the target oil and gas well includes:

[0090] The ratio between the amount of sand and gravel discharged and the oil layer thickness of the target oil and gas well is determined, and the ratio is used as the amount of sand and gravel per unit oil layer thickness.

[0091] In some embodiments, the target second duration corresponding to any oil and gas well is determined based on the liquid production intensity of the any oil and gas well, the amount of sand and gravel per unit oil layer thickness, and the sand content of the liquid produced by the any oil and gas well, including:

[0092] Obtaining the product of the liquid production intensity of any oil and gas well and the sand content of the liquid produced by any oil and gas well;

[0093] The ratio of the amount of sand and gravel per unit oil layer thickness to the product is obtained to obtain the target second time duration corresponding to any oil and gas well.

[0094] Figure 3 is a flow chart of a method for determining the duration of sand control provided in an embodiment of the present application, see Figure 3 , the method comprises the following steps.

[0095] 301. The electronic device obtains the production of multiple first oil and gas wells within a first time period after sand control is performed. The multiple first oil and gas wells perform sand control at different times. The multiple first oil and gas wells perform sand control after a second time period after production, and different first oil and gas wells correspond to different second time periods.

[0096] In an embodiment of the present application, when it is necessary to analyze the duration of sand control for oil and gas wells, the relevant data of the oil and gas wells that have been put into production can be used as a basis to determine the rules for sand control of these oil and gas wells based on the relevant data of the oil and gas wells that are found to have relatively good production or production maintenance during the production process. Then, for any oil and gas well, based on the above-mentioned prior data, the timing of sand control can be determined for the oil and gas well to achieve relatively good production and production maintenance.

[0097] The first oil and gas well is an oil and gas well that performs sand control after production. The second time length is the difference between the time when the first oil and gas well performs sand control and the time when production starts. The second time length can be obtained by extracting statistical data of the oil and gas wells or survey data of the oil and gas wells.

[0098] For the first duration, the first duration can be set by relevant technical personnel according to needs. For example, the first duration is half a year, and for another example, the first duration is one year. The embodiment of the present application does not limit this.

[0099] The electronic device obtains the production of the first oil and gas well within a first period of time after sand prevention is performed to measure the production and production maintenance of the first oil and gas well, so as to select the oil and gas wells with better conditions for subsequent processing.

[0100] For each first oil and gas well, the production of the first oil and gas well within the first time period after sand control can include the total production within the first time period and the production of each cycle within the first time period. The total production within the first time period can be used to determine the production of the first oil and gas well after sand control. The production of each cycle within the first time period can be used to determine the change in production of the first oil and gas well after sand control, thereby reflecting its production maintenance.

[0101] The second time lengths corresponding to the multiple first oil and gas wells are different in order to analyze the oil and gas wells with different second time lengths to determine the relationship between the second time length and production or production retention. In this way, we can subsequently analyze what target second time length to set to achieve better production and production retention of the oil and gas wells, that is, to achieve better sand control effect of the oil and gas wells.

[0102] 302. The electronic device determines a target oil and gas well from the multiple first oil and gas wells based on the production of the multiple first oil and gas wells, wherein the daily production of the target oil and gas well within the first time period is greater than a production threshold, and the rate of change of the production within the first time period is less than a rate of change threshold.

[0103] When the electronic device obtains the production of multiple first oil and gas wells, it can select oil and gas wells with relatively good production and production maintenance as target oil and gas wells. When further analysis is performed later, the relevant data of the target oil and gas wells can be directly used.

[0104] In order to ensure that both production and production retention are relatively good, when determining the target oil and gas wells, you can choose based on the two parts of production and production change rate.

[0105] As for the production threshold, in some embodiments, the production threshold may be a statistical value, and the production threshold is determined based on the daily production of multiple second oil and gas wells, and the second oil and gas wells are oil and gas wells that are subjected to sand control before production. After sand control before production, the production is generally higher, and thus, a production threshold is determined based on the daily production of multiple second oil and gas wells. In a specific possible embodiment, the production threshold may be the average of the daily production of multiple second oil and gas wells.

[0106] In other embodiments, the production threshold may be set by relevant technicians based on experience, or the production threshold may be determined by other methods, and the embodiment of the present application does not limit the setting method of the production threshold.

[0107] For the change rate threshold, in some embodiments, the change rate threshold may be a statistical value, and the change rate threshold is determined based on the change rate of the production of the plurality of second oil and gas wells. In a specific possible embodiment, the change rate threshold may be the average of the change rates of the production of the plurality of second oil and gas wells.

[0108] In other embodiments, the change rate threshold may be set by relevant technicians based on experience, or the change rate threshold may be determined by other methods, and the embodiment of the present application does not limit the setting method of the change rate threshold.

[0109] 303. The electronic equipment conducts a core displacement experiment on the liquid produced by the target oil and gas well and obtains the experimental results.

[0110] The core flooding experiment is an experiment that simulates real reservoir conditions. According to the real environmental data of the target oil and gas wells, the environmental setting parameters in the core flooding experiment are updated so that the simulated environment during the experiment is the same as the real environment of the target oil and gas wells. In this way, the relevant data of the liquid of the target oil and gas wells obtained in the experiment can be consistent with the relevant data of the liquid produced by the target oil and gas wells.

[0111] The equipment required for the core displacement experiment can be selected by relevant technical personnel based on the actual environmental data of the target oil and gas well, such as temperature sensors, pressure sensors, circulation pumps, etc.

[0112] The experimental data may include the amount of liquid produced, that is, the output. The experimental data may also include the sand content of the produced liquid. The experimental data may also include other data, which is not limited in the embodiments of the present application.

[0113] 304. The electronic device extracts the sand content in the liquid produced by the target oil and gas well within the first period of time from the experimental results.

[0114] After the electronic device obtains the experimental results, it can directly extract the sand content of the liquid produced by the target oil and gas well during the first period of time. The produced liquid may include pure liquid and sand, and the sand content refers to the ratio of the amount of sand in the produced liquid to the amount of the produced liquid.

[0115] Step 303 and step 304 are processes for detecting the liquid produced by the target oil and gas well to obtain the sand content in the liquid produced by the target oil and gas well within the first time period. The above detection process is implemented through a core displacement experiment. In some embodiments, the electronic device can also determine the sand content through statistical data. For example, the liquid produced by the target oil and gas well is collected and separated to determine the ratio of the amount of sand and gravel in the produced liquid to the amount of produced liquid. This embodiment of the application is not limited to this.

[0116] 305. The electronic device determines the amount of sand and gravel discharged from the target oil and gas well within the second time period based on the sand content and the production of the target oil and gas well within the second time period corresponding to the target oil and gas well.

[0117] After the electronic device obtains the sand content of the liquid produced by the target oil and gas well, it can obtain the production of the target oil and gas well in the second time period, so as to determine the amount of sand and gravel discharged by the target oil and gas well in the second time period. The amount of sand and gravel discharged in the second time period is the amount of sand and gravel discharged after sand control.

[0118] In some embodiments, the electronic device can obtain the product of the sand content and the production of the target oil and gas well in the second time period corresponding to the target oil and gas well, and use the product as the amount of sand and gravel discharged by the target oil and gas well in the second time period.

[0119] 306. The electronic device determines the amount of sand and gravel per unit oil layer thickness based on the amount of sand and gravel discharged and the oil layer thickness of the target oil and gas well.

[0120] After the electronic device learns the amount of sand and gravel discharged, it can obtain the oil layer thickness of the target oil and gas well, and can determine the amount of sand and gravel per unit oil layer thickness based on the two. The oil layer thickness of the target oil and gas well can be obtained by statistics or measurement, which is not limited in the embodiments of the present application. In this way, the factor of oil layer thickness is excluded to analyze the number of days of sand control of the oil and gas well.

[0121] In some embodiments, the electronic device may determine the ratio between the amount of sand and gravel discharged and the oil layer thickness of the target oil and gas well, and use the ratio as the amount of sand and gravel per unit oil layer thickness.

[0122] 307. The electronic device responds to a time determination instruction for sand prevention measures for any oil and gas well, and determines a target second time duration corresponding to the any oil and gas well based on the liquid production intensity of the any oil and gas well, the amount of sand and gravel per unit oil layer thickness, and the sand content of the liquid produced by the any oil and gas well. The target second time duration is used to indicate the time duration for sand prevention measures for the any oil and gas well after production.

[0123] After the electronic device determines the amount of sand and gravel per unit oil layer thickness, it can be used as a basis for subsequent analysis of oil and gas wells that have not yet taken sand prevention measures, combined with the liquid production intensity of the oil and gas well and the sand content of the liquid produced by the oil and gas well, to determine a target second time for the oil and gas well that conforms to its actual situation.

[0124] The production intensity refers to the daily production of an oil well under a unit production pressure difference, and its unit can be cubic meter / (meter*day). The production intensity of the oil and gas well is generally required to be no greater than the critical production intensity. The critical production intensity is a standard for production intensity.

[0125] Of course, after determining the target second time duration, the target second time duration can also be used to prevent sand from forming in the oil and gas wells.

[0126] In some embodiments, the process of determining the target second duration may be:

[0127] The electronic device obtains the product of the liquid production intensity of any oil and gas well and the sand content of the liquid produced by any oil and gas well, and then obtains the ratio of the amount of sand and gravel per unit oil layer thickness to the product to obtain the target second time length corresponding to any oil and gas well.

[0128] For example, suppose A is the amount of sand and gravel per unit oil layer thickness, cubic meter. B is the sand content of the oil and gas well, %. C is the liquid production intensity of the oil and gas well, cubic meter / (meter*day). The target second duration is represented by M. Then the target second duration can be determined as follows:

[0129] M=A / (B*C)

[0130] A specific example is provided below, which is aimed at an oil and gas well to illustrate the method provided by the present application. Assume that the oil and gas well is X6-6 well, wherein various data of the oil and gas well may be: reservoir section 1011.2m-1017.3m, thickness 6.1m, production layer NmⅡ.

[0131] Assume that according to the free sand displacement (that is, the amount of sand and gravel per unit oil layer thickness) during the production process of the previous sand-producing well (target oil and gas well), the amount of sand and gravel per unit oil layer thickness A is 0.2m 3 / m, the critical liquid extraction intensity D is 2.2m 3 / md, the meter liquid extraction intensity (also known as liquid extraction intensity) C in the production process is 1.8m 3 / md, the sand content of the formation fluid (that is, the sand content rate) B is 0.013%. In order to determine the sand control opportunity of the oil and gas well, it can be calculated as follows:

[0132] N = A / (C × B)

[0133] =0.2 / (1.8×0.013%)

[0134] =854.7 days

[0135] According to the calculation results, sand prevention measures can be considered 854.7 days after production starts.

[0136] By adopting the early sand discharge and liquid production, the oil well produces at a level not greater than the critical sand production level, and then taking sand control measures at the right time after the free sand in the formation is discharged, the production retention rate after sand control has increased from the original 68.2% to 85.7%, and the effective period of sand control has been extended by more than 100 days. By steadily controlling the migration speed and discharge intensity of the filling sand, while reducing the probability of sand jamming and sand burial caused by the sudden discharge of the filling sand, it creates conditions for the next step to improve the sand control production retention rate and effective period, and ensure the sand control effect.

[0137] The embodiment of the present application analyzes the relevant data of the oil and gas wells that have been put into production, selects the oil and gas wells with relatively good production and production maintenance, and uses these oil and gas wells as references to determine the amount of sand and gravel per unit oil layer thickness, so that when the sand control opportunity of any oil and gas well needs to be analyzed later, the amount of sand and gravel per unit oil layer thickness, the sand content of the oil and gas well itself, and the liquid production intensity can be used to analyze the sand control opportunity suitable for the oil and gas well. Based on sufficient data and combined with the data of the oil and gas well itself, the sand control duration determined is more accurate and the sand control effect is better.

[0138] All the above optional technical solutions can be combined in any way to form optional embodiments of the present application, and will not be described in detail here.

Based on sufficient data and combined with the data of the oil and gas well itself, the sand control duration determined is more accurate and the sand control effect is better.
