Optimization method, equipment and system for complex scattered fault block oil field group use sequence

Abstract

The invention provides an optimization method and system for a complex scattered fault block oil field group use sequence, computer equipment and a computer readable storage medium, and relates to thetechnical field of oil and gas field exploration and development. The method comprises the steps of determining a standard factor set influencing the development effect of each oil-bearing fault block according to actual information corresponding to an oil field; constructing a hierarchical structure of a multi-level and multi-factor risk comprehensive evaluation index system according to the standard factor set; determining weight information of each standard factor index in the standard factor set according to the hierarchical structure of the risk comprehensive evaluation index system; anddetermining production sequence information of the oil field group according to the standard factor set and the weight information. According to the invention, the improved analytic hierarchy processis adopted to optimize the sequential production sequence of different oil reservoirs of the complex oil-bearing fault block group, so that benefit maximization of oil reservoir project management isrealized, and the defects of a common analytic hierarchy process in the prior art are overcome.

Description

technical field [0001] The present invention relates to the technical field of exploration and development of oil and gas fields, in particular to the exploration and development technology of oilfield group reservoirs containing multiple oil-bearing fault blocks, and specifically relates to an optimization method, system and computer equipment for the production sequence of oilfield groups with complex scattered fault blocks and computer readable storage media. Background technique [0002] For complex fault-block oilfield groups, due to differences in structures, reservoir physical properties, oil and gas migration and Formation depth, reservoir energy, crude oil quality, surface conditions, etc. For such oilfield groups, especially overseas projects, how to prioritize the development of high-quality fault blocks, shorten the investment recovery period, and maximize profits has always been the core issue. Therefore, it is very important to choose a method that can effect...

Problems solved by technology

[0004] However, the commonly used AHP also has some deficiencies, which are mainly manifested in: ①The commonly used AHP adopts the "1-9" scale method to establish the judgment matrix. Sometimes distorted when compared to

② The judgment matrix involved in the AHP requires consistency, but it is often not satisfied in the actual operation process. At this time, the judgment matrix needs to be corrected. The common method is to rebuild a judgment matrix, but this method is time-consuming and laborious
