[0036] Figure 1 A flowchart of a target rig determination method provided for an embodiment of the present application, the embodiment of the present application can be applicable to the case of selecting a rig suitable for drilling development in a target area. The method can be performed by a target rig determination device, which can be realized in the form of hardware and / or software, and can be configured in an electronic device. As shown in Figure 1 The method comprises:
[0037] S110, for each rig, determining the average value and the standard deviation of the target parameter in the process of drilling in the target area; wherein the target parameter comprises at least one of the mechanical drilling speed, the non-production time, the moving distance, the moving period and the moving cost.
[0038] Wherein, the target area can be an area that needs to be drilled. Each rig can be a candidate rig that can be used for drilling in the target area.
[0039] In the embodiments of the present application, in the process of selecting a target rig suitable for drilling in the target area, the target parameters of each rig in the target area during drilling can be determined first, so as to further evaluate the performance of each rig in the target area during drilling according to the target parameters. The target parameters can include at least one of the mechanical drilling speed, the non-production time efficiency, the moving distance, the moving cycle and the moving cost. The mechanical drilling speed is the rotating speed of the rig during drilling in the target area, and the higher the mechanical drilling speed, the better the drilling performance of the rig in the target area. The non-production time efficiency is the percentage of the non-production time in the drilling working time. The non-production time includes the working time for handling accidents, the working time for equipment repair, the working time for organizational shutdown, the working time for natural shutdown, the working time for handling complex situations and other time. The smaller the non-production time efficiency, the better the drilling performance of the rig in the target area. The moving distance is the distance from the current location of the rig to the location to be drilled. The shorter the moving distance, the more suitable the rig is for drilling in the target area. The moving cycle is the time required from disassembling the rig to assembling the rig at the location to be drilled. The shorter the moving cycle, the more suitable the rig is for drilling in the target area. The moving cost is defined as the cost required from disassembling the rig to assembling the rig at the location to be drilled. The lower the moving cost, the more suitable the rig is for drilling in the target area.
[0040] S120, determining a preferred rate of the rig according to the average value of the target parameters of the rig, and determining a comprehensive standard deviation of the rig according to the standard deviation of the target parameters of the rig.
[0041] For example, for each rig, the target parameters of the rig during drilling in the target area are determined in each drilling process, the average value of the target parameters determined in each drilling process is calculated, the preferred rate of the rig is determined according to the average value, and the standard deviation of the target parameters of the rig is calculated, and the comprehensive standard rate of the rig is determined according to the standard deviation.
[0042] Specifically, the preferred rate of the rig is determined according to the average value of the target parameters of the rig, which can be specifically determined by taking the performance of the rig corresponding to the comprehensive influence of each target parameter as the preferred rate of the rig according to the correlation between the average value of the target parameters of the rig and the performance of the rig, and the influence degree of each target parameter on the performance of the rig. The comprehensive standard deviation of the rig is obtained by comprehensively considering the standard deviations of each target parameter of the rig according to the correlation between the standard deviation of the target parameters of the rig and the performance of the rig, and the influence degree of each target parameter on the performance of the rig.
[0043] S130, selecting a target rig to be drilled according to the preferred rate and the comprehensive standard deviation of the rig.
[0044] Since the preference rate of the drilling rig is calculated according to the average value of the target parameter of the drilling rig, and the average value of the target parameter reflects the performance of the drilling rig, the preference rate of the drilling rig can also reflect the performance of the drilling rig. Since the comprehensive standard deviation of the drilling rig is calculated according to the standard deviation of the target parameter of the drilling rig, and the standard deviation of the target parameter can reflect the performance of the drilling rig, the comprehensive standard deviation of the drilling rig can also reflect the performance of the drilling rig. The target drilling rig with good performance in drilling in the target area can be selected from the drilling rigs according to the preference rate and the comprehensive standard deviation of the drilling rig, and the target drilling rig is used to drill in the target area, so that the performance is good and the drilling efficiency is improved.
[0045] The technical scheme of the embodiment of the application determines the average value and the standard deviation of the target parameter of each drilling rig in the process of drilling in the target area; the target parameter includes at least one of the mechanical drilling speed, the non-production time, the moving distance, the moving period and the moving cost; the preference rate is determined according to the average value of the target parameter of the drilling rig, and the comprehensive standard deviation is determined according to the standard deviation of the target parameter of the drilling rig; and the target drilling rig to be drilled is selected according to the preference rate and the comprehensive standard deviation. The above scheme can determine the preference rate and the comprehensive standard deviation of each drilling rig according to the target parameter of each drilling rig in the process of drilling in the target area, quantitatively represents the fitness and performance of the drilling rig to the drilling in the target area, accurately selects the target drilling rig suitable for drilling in the target area, and improves the accuracy of the selection of the target drilling rig and the consistency with the drilling in the target area.
[0046] Figure 2 A flowchart of a target drilling rig determination method provided for another embodiment of the application is based on the above-described embodiment and is optimized. The schemes not described in detail in the embodiment of the application are described in the above-described embodiment. As shown in Figure 2 The method of the embodiment of the application specifically includes the following steps:
[0047] S210, for each drilling rig, if the drilling rig has a drilling history in the target area, the target parameter of the drilling rig in each drilling process is obtained.
[0048] S220, the average value of the target parameter in each drilling process is calculated, and the standard deviation of the target parameter of the drilling rig in the drilling process is calculated according to the target parameter in each drilling process and the average value.
[0049] S230, if the drilling rig does not exist in the target area drilling history, the maximum value of the average value of the target parameter corresponding to other drilling rigs is taken as the average value of the target parameter corresponding to the drilling rig; wherein the target parameter includes at least one of the mechanical drilling speed, non-production time, moving cycle and moving cost; if the target parameter is the mechanical drilling speed, the maximum value is the minimum value, and if the target parameter is at least one of the non-production time, the moving cycle and the moving cost, the maximum value is the maximum value.
[0050] S240, the maximum value of the standard deviation of the target parameter corresponding to other drilling rigs is taken as the standard deviation of the target parameter corresponding to the drilling rig.
[0051] For example, suppose the i-th drilling rig drills well m in block B. The mechanical drilling speed of the drilling rig in each well in the area is The average value of the mechanical drilling speed of the i-th drilling rig in block B is:
[0052]
[0053] The standard deviation of the mechanical drilling speed of the i-th drilling rig in block B is:
[0054]
[0055] Similarly, n drilling rigs are obtained. Suppose the average value of the mechanical drilling speed of the n-th drilling rig in block B is The standard deviation of the mechanical drilling speed is The average value of the mechanical drilling speed needs to be de-dimensioned.
[0056] The maximum value of the average value of the mechanical drilling speed is:
[0057]
[0058] The dimensionless average mechanical drilling speed of the i-th drilling rig is:
[0059]
[0060] If the drilling rig j does not drill well in block B, the average mechanical drilling speed and the standard deviation of the j-th drilling rig in block B are as follows:
[0061]
[0062] Suppose the i-th drilling rig drills well m in block B. The non-production time of the drilling rig in each well is The average value of the non-production time of the i-th drilling rig in block B is:
[0063]
[0064] The standard deviation of the non-production time of the i-th drilling rig in block B is:
[0065]
[0066] Similarly, we can derive the average non-productive efficiency of n drilling rigs in block B as follows: The standard deviation of non-production timeliness is Non-production time-efficiency averages need to be standardized.
[0067] The maximum and minimum values of the average non-production failure rate are:
[0068]
[0069] The average non-productive efficiency of the i-th drilling rig is:
[0070]
[0071] If drilling rig j has not drilled in Block B, then the average value and standard deviation of drilling rig j during non-productive periods in Block B are as follows:
[0072]
[0073] Let there be n drilling rigs, and the relocation distances from each rig to the well site be L1, L2, L3, ..., L... n .
[0074] The maximum value of the average moving distance is:
[0075]
[0076] The dimensionless relocation distance of the i-th drilling rig is:
[0077]
[0078] Suppose that the i-th drilling rig is moved m times in block B, with each move having a cycle of T1, T2, T3, ..., T. m (Converted to unit relocation distance), then the average relocation distance for the i-th drilling rig during the relocation cycle is:
[0079]
[0080] The standard deviation of the relocation cycle of the i-th drilling rig in Block B is:
[0081]
[0082] Similarly, the average relocation cycle of n drilling rigs can be obtained as follows: The standard deviation of the moving cycle is The average moving cycle needs to be dimensionless.
[0083] The maximum and minimum of the average moving period are:
[0084]
[0085] The dimensionless average moving period of the ith drilling rig is:
[0086]
[0087] If the drilling rig j has not drilled in the B block, the average moving period and the standard deviation of the drilling rig j in the B block are as follows:
[0088]
[0089] Suppose the ith drilling rig moves m times, and each time the moving cost is M1, M2, M3,..., Mm. m The average moving cost of the ith drilling rig is:
[0090]
[0091] The standard deviation of the moving cost of the ith drilling rig in the B block is:
[0092]
[0093] Similarly, the average moving cost per unit moving distance of the n drilling rigs is: The standard deviation of the moving cost is: The average moving time needs to be de-dimensioned.
[0094] The maximum and minimum of the average moving cost are:
[0095]
[0096] The dimensionless average moving cost of the ith drilling rig is:
[0097]
[0098] If the drilling rig j has not drilled in the B block, the average moving cost and the standard deviation of the drilling rig j in the B block are as follows:
[0099]
[0100] S250, according to the average value of the target parameter of the drilling rig, determining the preferred rate of the drilling rig, and according to the standard deviation of the target parameter of the drilling rig, determining the comprehensive standard deviation of the drilling rig.
[0101] S260, according to the preferred rate and the comprehensive standard deviation of the drilling rig, selecting a target drilling rig to be drilled.
[0102] The embodiment of the present application provides a target rig determination method, if the rig has a drilling history in the target area, target parameters of the rig in each drilling process are acquired; average values of the target parameters in each drilling process are calculated, and standard deviations of the target parameters of the rig in the drilling process are calculated according to the target parameters in each drilling process and the average values. If the rig has no drilling history in the target area, extreme values of average values of target parameters corresponding to other rigs are taken as average values of the target parameters corresponding to the rig; wherein the target parameters include at least one of a mechanical drilling speed, a non-production time, a moving period and a moving cost; if the target parameter is the mechanical drilling speed, the extreme value is the minimum value, and if the target parameter is at least one of the non-production time, the moving period and the moving cost, the extreme value is the maximum value; a maximum value of standard deviations of the target parameters corresponding to other rigs is taken as the standard deviation of the target parameters corresponding to the rig. The above scheme determines the average value and the standard deviation of the target parameters of the drilling according to whether the rig has the experience of drilling in the target area, thereby improving the accuracy of the average value and the standard deviation of the target parameters.
[0103] Figure 3 A flow chart of a target rig determination method provided by another embodiment of the present application is shown in the figure. The embodiment of the present application is optimized based on the above embodiment, and the schemes not described in detail in the embodiment of the present application are described in the above embodiment. As shown in the figure, Figure 3 the method of the embodiment of the present application specifically includes the following steps:
[0104] S310, for each rig, determining average values and standard deviations of target parameters in the process of drilling in the target area of the rig; wherein the target parameters include at least one of a mechanical drilling speed, a non-production time, a moving distance, a moving period and a moving cost.
[0105] S320, if the target parameters are at least three, a polygon coordinate system is established, the center of the polygon is taken as the coordinate origin, and each target parameter is taken as a vertex of the polygon.
[0106] For example, if the target parameters are at least three, a polygon coordinate system can be established, the center of the polygon is taken as the coordinate origin, and each target parameter is taken as a vertex of the polygon. Specifically, taking five target parameters as an example, as shown in the figure, assuming that the weights of the target parameters are equal, a regular pentagon coordinate system can be established, and the coordinate origin is the center of the regular pentagon. If the weights of the target parameters are not equal, a non-regular polygon coordinate system can be established according to the relative size relationship of the weights of the target parameters, and the distance between the target parameter as the vertex and the coordinate origin is positively correlated with the weight of the target parameter. For example, Figure 4 Figure 4 As shown, the numerical advantage direction of determining the average value of the mechanical drilling speed is the direction from the center of the regular pentagon to the vertex, the greater the average value of the mechanical drilling speed of the drilling rig, the more likely to be selected as the drilling rig used for the well to be drilled, so the average value of the mechanical drilling speed index advantage direction is consistent with the numerical direction. The greater the average value of the non-production time efficiency, the average value of the moving distance, the average value of the moving cycle and the average value of the moving cost, the more suitable it is to be selected as the advantage direction of the drilling rig used for the well to be drilled, so the average value of the non-production time efficiency, the average value of the moving distance, the average value of the moving cycle and the average value of the moving cost index advantage direction is opposite to the numerical direction.
[0107] S330, determining the distance between the coordinate origin and the vertex of the polygon according to the average value of the target parameter; wherein the distance between the coordinate origin and the vertex of the mechanical drilling speed is proportional to the average value of the mechanical drilling speed, the distance between the coordinate origin and the vertex of the other target parameter is inversely proportional to the average value of the other target parameter, and the other target parameter includes non-production time efficiency, moving cycle and moving cost.
[0108] For example, assuming that the default advantage direction is from the polygon origin to each vertex, for the target parameter positively correlated with the performance of the drilling rig, the direction in which the value increases in the polygon is consistent with the advantage direction, and for the target parameter negatively correlated with the performance of the drilling rig, the direction in which the value increases in the polygon is opposite to the advantage direction, that is, the greater the average value of the mechanical drilling speed, the greater the distance between the coordinate origin and the vertex of the mechanical drilling speed, and the greater the other target parameters (such as non-production time efficiency, moving cycle and moving cost), the smaller the distance between the coordinate origin and the vertex of the other target parameters. For example, the polygons representing the average values of the target parameters of the i, j, k and g drilling rigs can be obtained as shown in Figure 5 、 6 、7、8, the line segment from the origin to each target parameter vertex of the regular pentagon is the coordinate axis of each target parameter, and the values of each target parameter are marked on each coordinate axis. The polygon formed by connecting the points after marking the values of each target parameter on the coordinate axis is inside. The polygon area formed by the target parameters of the i drilling rig is Si, the polygon area formed by the target parameters of the j drilling rig is Sj, the polygon area formed by the target parameters of the k drilling rig is Sk, and the polygon area formed by the target parameters of the g drilling rig is Sg.
[0109] S340, determining the preferred rate of the drilling rig according to the constructed polygon and the preset polygon; wherein the preset polygon is a polygon formed according to the distance between the coordinate origin and the vertex of the target parameter determined by the maximum value of the average value of the target parameter.
[0110] The preset polygon can be determined according to actual conditions, for example, a polygon formed when each normalized target parameter is 1, or a polygon formed by expanding the polygon by N times, where N is greater than or equal to 1.
[0111] The preferred rate of the drilling rig can be determined according to the size relationship between the constructed polygon and the preset polygon.
[0112] In the embodiment of the present application, the preferred rate of the drilling rig is determined according to the constructed polygon and the preset polygon, and the method comprises the following steps.
[0113] The preferred rate of the drilling rig is determined according to the ratio of the area of the constructed polygon to the area of the preset polygon.
[0114] The average value of the dimensionless mechanical drilling speed of the ith drilling rig The average value of the non-normal aging The average value of the moving period The average value of the moving distance The average value of the moving cost The points are connected to obtain a closed polygon, and the area Si of the closed polygon is calculated, and the area of the preset polygon is S. The preferred rate of the ith drilling rig is defined as F. i ,F i The calculation formula is as follows.
[0115]
[0116] S is the preset area, and S i is the area of the closed polygon of the ith drilling rig, as shown in the following formula. Figure 5 The preferred rates of different drilling rigs F j , F k , and F g are obtained in the same way, as shown in the following formulas. Figure 6 , Figure 7 , Figure 8 When the closed figure is a straight line or a point, the closed area is 0.
[0117]
[0118] It can be found through analysis that the larger the closed polygon area S i is, the closer the indexes are to the value advantage direction. In order to eliminate the influence of different coordinate axis scales on S i , the ratio of the entire regular pentagonal coordinate system is selected, that is, F i is used as the preferred drilling rig index.
[0119] max{F i , F j , F k ...... F gThe corresponding drilling rig should be the one with the inclination selected as the drilling rig of the well to be drilled.
[0120] S350, determine the standard deviation of the target parameters of the drilling rig respectively corresponding to the standard deviation weight value.
[0121] S360, weight the standard deviation of each target parameter of the drilling rig according to the standard deviation weight value to obtain the comprehensive standard deviation of the drilling rig.
[0122] The comprehensive standard deviation C is established, and the calculation formula of C is:
[0123] C=c v σ v +c E σ E +c L σ L +c T σ T +c M σ M ;
[0124] Wherein, c v is the mechanical drilling speed standard deviation weight value, c E is the non-normal time limit standard deviation weight value, c T is the moving cycle standard deviation weight value, c M is the moving cost standard deviation weight value, c L is the moving distance standard deviation weight value, and the moving distance standard deviation σ L is 0 by default. The relative size relationship of the standard deviation weight value corresponding to each target parameter should be consistent throughout the process. When it is considered that each index has the same weight, c v =c E =c T =c M =c L =0.2.
[0125] The comprehensive standard deviation C i of the i-th drilling rig is:
[0126]
[0127] C i is smaller, indicating that the i-th drilling rig is more stable and less uncertain, and should be inclined to be selected as the drilling rig of the well to be drilled.
[0128] S370, determine the comprehensive weight value corresponding to the preferred rate and the comprehensive standard deviation respectively.
[0129] S380, subtract the product of the comprehensive standard deviation and the corresponding comprehensive weight value from the product of the preferred rate and the corresponding comprehensive weight value to obtain the preferred comprehensive index.
[0130] S390, selecting a target rig for drilling the well according to the preferred comprehensive index.
[0131] A rig preferred comprehensive index R is established, and the calculation formula of R is:
[0132] R = R F F - R C C or
[0133] Wherein, R F is the comprehensive weight value of the rig preferred rate, R C is the comprehensive weight value of the comprehensive standard deviation, when the oilfield prefers the rig only considering the rig preferred rate, not considering the rig stability, that is, the comprehensive standard deviation, then R F = 1, R C = 0; when the oilfield prefers the rig only considering the rig stability, that is, the comprehensive standard deviation, not considering the rig preferred rate, then R F = 0, R C = 1; when the oilfield considers the rig preferred rate and the rig stability at the same time, and the rig preferred rate is more important, then R F > R C > 0, and R F + R C = 1; when the oilfield considers the rig preferred rate and the rig stability at the same time, and the rig stability is more important, then R C > R F > 0, and R F + R C = 1.
[0134] The i-th rig preferred comprehensive index is:
[0135] R i = R F F i - R C C i ;
[0136] The rig corresponding to the maximum R i should be selected as the rig for drilling the well.
