Description

Technical Field

[0001] The invention belongs to the technical field of evaluation methods and relates to a performance evaluation method for an underground operation team based on a hierarchical analysis method. Background Art

[0002] At present, the performance evaluation of the underground operation management team is mainly based on the effect of specific process measures and economic indicators, without considering factors such as process type, safety and environmental protection, and well control. In addition, there is no unified standard for evaluation, and most of the evaluation indicators are about single measures. It is particularly important to promote problem rectification and improve the quality and management level of underground operations through comprehensive and reasonable evaluation of underground operation teams.

[0003] Liu Jiansheng, Wu Tianjiang, Tian Yuhong and others published a paper titled "Research and Application of Downhole Operation Management System Based on Market-oriented Team" (IFEDC2016689) at the 2016 "Oil and Gas Field Exploration and Development" conference, which introduced a downhole operation information management system, including five modules: measures operation, maintenance operation, information query, design management and system maintenance. The system is responsible for the entry of grassroots personnel to evaluate the performance of the operation effect, and the construction team is automatically evaluated and ranked according to the calculation formula, but the specific calculation method is not clear. Li Xianyong published a 2016 engineering master's thesis "Research on the Management Plan of Contractors for the A Oil Production Plant Project" at China University of Petroleum (East China), which used the contractor evaluation model and selection method based on G-AHP to determine the appropriate contractor for the project, designed a contractor performance evaluation index system including construction quality satisfaction, construction progress control satisfaction, HSE risk control satisfaction and construction technology satisfaction, and dynamically managed the contractors. It did not distinguish between the types of engineering projects, resulting in low downhole operation quality. Summary of the invention

[0102] Step 2: Calculate the weight of each assessment indicator and determine the assessment model of the underground operation team for each operation;

[0103] Specifically, step 2.1, determine the importance ratio of each assessment indicator of each task and construct a judgment matrix;

[0104] Collect the scores of M assessment indicators of N sample underground operation teams for each operation; compare the scores of M assessment indicators in pairs. When the value is <0.5, the importance ratio of the two indicators is 8 or 9; when the value is 0.5-0.7, the importance ratio of the two indicators is 6 or 7; when the value is 0.7-0.9, the importance ratio of the two indicators is 4 or 5; when the value is 0.9-1, the importance ratio of the two indicators is 2 or 3; when the value is 1, the importance ratio of the two indicators is The ratio is 1; when the value is 1.01-1.1, the current importance ratio of the two indicators is 1 / 2 or 1 / 3; when the value is 1.1-1.4, the current importance ratio of the two indicators is 1 / 4 or 1 / 5; when the value is 1.4-2, the current importance ratio of the two indicators is 1 / 6 or 1 / 7; when the value is >2, the current importance ratio of the two indicators is 1 / 8 or 1 / 9; calculate the arithmetic mean of the current importance ratio of the two indicators of N samples to get the current importance ratio of the two indicators.

[0106] Step 2.2.1, calculate the consistency index CI:

[0107]

[0108] In the formula, n is the number of indicators, λ maxis the maximum eigenvalue of the judgment matrix;

[0109] Step 2.2.2, calculate the consistency ratio CR:

[0110]

[0111] Among them, RI is the random consistency index, and the RI value corresponding to n can be obtained by looking up the table;

[0112] Step 2.2.3: If the RI value is less than 0.1, the consistency is satisfied and go to the next step; otherwise, return to the previous step.

[0113] Step 2.3: Calculate the weights of the assessment indicators and obtain the performance assessment model for the underground operation team.

[0114] Step 2.3.1, normalize the judgment matrix by column to obtain a normalized judgment matrix;

[0115] Step 2.3.2: Sum and average each row of the normalized judgment matrix to obtain the weight of each assessment indicator, that is, to obtain the underground operation team assessment model for each operation.

[0116] Step 3: Score the underground operation team for individual assessment indicators according to each operation assessment standard;

[0117] Step 4: Obtain a comprehensive score for the underground operation team based on the scores of individual assessment indicators and the corresponding underground operation team assessment model; specifically, multiply the score of each assessment indicator by the corresponding assessment indicator weight, and then sum them up to obtain the comprehensive score for the underground operation team.

[0118] Step 5: Evaluate the underground operation team based on the comprehensive score.

[0119] In this embodiment, if the total score is <60 points, it is considered unqualified; if 60 points ≤ total score <70 points, it is considered basically qualified; if 70 points ≤ total score <90 points, it is considered qualified; if the total score is ≥90 points, it is considered excellent.

[0120] Example 4

[0121] Taking a certain measures operation team as an example, its contractor completed 7 wells in a certain quarter, and the wells were opened normally for more than 30 days after completion. The average daily oil increase of 4 wells was greater than the geological design oil increase, the average daily oil increase of 2 wells reached 85% of the geological design oil increase, and the average daily oil increase of 1 well reached 75% of the geological design oil increase.

[0122] The performance evaluation method of underground operation team based on hierarchical analysis method includes the following steps:

[0123] Step 1: Determine 6 management department assessment indicators, including standard management, performance of production safety and production technology managers, performance of departmental duties, safety indicators, construction progress organization, and problem rectification, and 9 team assessment indicators, including production organization, equipment management, personnel management, data management, construction site management, well control management, measure effect, process quality, and problem rectification, for a total of 15 performance assessment indicators for underground operation teams; the assessment standards are the assessment standards for measure operations;

[0124] Step 2: Determine the importance ratio of each pair of assessment indicators of the current measure operation and construct a judgment matrix;

[0125] Table 1: Judgment matrix for performance evaluation of measures

[0126]

[0127]

[0128] Among them, A-standard management, B-performance of production safety and production technology manager, C-performance of department, D-safety index, E-construction progress organization, F-problem rectification, G-production organization, H-equipment management, I-personnel management, J-data management, K-construction site management, L-well control management, M-measure effect, N-process quality, O-problem rectification,

[0129] Let i be the number of rows and j be the number of columns, then the meaning of the element Aij in the judgment matrix is: the importance of the i-th indicator relative to the j-th indicator.

[0130] Calculate the consistency index CI:

[0131]

[0132] In the above formula, n = 15, λ max =15.046, CI=0.0032;

[0133] Calculate the consistency ratio CR:

[0134]

[0135] In the above formula, n = 15, RI = 1.59, CR = 0.002;

[0136] Then CR=0.002<0.1, which satisfies consistency.

[0137] Normalize the judgment matrix by column, such as A11, and calculate it as:

[0138]

[0139] Get the normalized judgment matrix:

[0140] Table 2: Judgment matrix for performance evaluation of measures

[0141]

[0142]

[0143] Each row is summed and averaged to get the weight of each assessment indicator. For example, the weight of assessment indicator A is calculated as:

[0144]

[0145] Finally, the weights of 15 assessment indicators of the measure operation team are obtained, that is, the assessment model of the measure operation team is:

[0146] [0.084, 0.049, 0.198, 0.026, 0.094, 0.049, 0.027, 0.058, 0.026, 0.027, 0.087, 0.094, 0.084, 0.049, 0.049]

[0147] Step 3: Score the underground operation team for individual assessment indicators according to each operation assessment standard;

[0148] Construction progress organization scoring standard: full score for cumulative completion of ≥9 wells in a quarter, 10 points will be deducted for each well reduced, and no points will be awarded for less than 2 wells;

[0149] Scoring standard for measures effect: if the oil well is opened normally for more than 30 days after the completion of the measures, and the average daily oil increase is greater than or equal to the geological design oil increase, each well will get 10 points; if it is ≥80% and <100%, each well will get 8 points; if it is ≥60% and <80%, each well will get 3 points; if it is <60%, no points will be awarded;

[0150] The underground operation management department scores the assessment indicators of the management department to which the team belongs, the underground operation supervision department scores the assessment indicators of production organization, equipment management, personnel management, data management, construction site management, well control management, process quality, etc., and the underground operation unit scores the effectiveness of the measures. The scores of the individual assessment indicators of the team for this measure are: [100, 80, 82, 100, 80, 100, 95, 90, 95, 90, 95, 59, 50, 100].

[0151] Step 4: Multiply the score of each assessment indicator by the corresponding assessment indicator weight, and then sum them up to get the comprehensive score of the underground operation team, which is 86.3 points;

[0152] Step 5. Based on the classification evaluation standards, the team responsible for this measure is evaluated as qualified and can continue to be selected to further strengthen problem rectification.
