Research On Production Decision Of Oil Reservoir Management

At present most of oil fields in our country entered the mid and late development part, they faced with questions in various aspects, such as technology, economy, politics and so on. How to maintain the stable production, satisfy the state economy development to the petroleum output demand; how to determine the development plan according to the dynamic transformation rule of the oil field; how to obtain the greatest output by the lowest cost, pursue the maximum benefit. These three aspect question is precisely the key question which the oil-field development plan faces and needs to solve, therefore present each big oil field a"production decision"will place the extremely important position.This article synthesis utilization petroleum theories and so on technical economics, operations research, system engineering, through conduct the comparison research to the overseas various petroleum company oil reservoir production decision method, in the oil field existing oil reservoir decision system foundation, the question which in the analysis decision process exists, the basis oil field history data, has established the oil field management decision appraisal system from the development appraisal and the economic evaluation two aspects, and has carried on the oil reservoir management production benefit analysis, mainly includes the oil gas output analysis and the oil gas production cost expense analysis. Establishes the old well output, the measure output and the new well output economical output model, simultaneously uses the optimized principle, established oil field production decision-making two"the optimized model", including the output assignment optimization model, the measure output optimization model and unifies some oil field concrete data to carry on the simulation operation.
