【摘要】：如何从技术和经济的角度选择火山岩气藏最优开发方案是目前急需解决的问题。根据火山岩气藏开发方案优选指标的构建原则,确定了开发方案的7个优选指标。采用改进的层次分析法(AHP),与熵权法和逼近于理想解排序法(TOPSIS)相结合,建立了基于改进的AHP-熵权法和TOPSIS的火山岩气藏开发方案优选模型,并以松辽盆地某区块火山岩气藏8个决策开发方案优选为例验证了模型的有效性。结果表明,利用所建立的优选模型计算8个决策方案距离正理想方案的接近程度分别为0.294 7,0.504 1,0.679 8,0.767 5,0.316 5,0.640 7,0.621 3和0.254 6,根据决策方案距离正理想点最小优选原则,得到最优方案为决策方案8.优选结果可为石油公司做出决策提供辅助参考,具有一定的实际和理论意义。
[Abstract]:How to select the optimal development plan of volcanic gas reservoir from the technical and economic point of view is an urgent problem to be solved at present. According to the construction principle of the optimal selection index of the volcanic gas reservoir development scheme, the 7 optimal selection indexes of the development plan are determined. Based on the improved Analytic hierarchy process (AHP) method and the entropy weight method and the approximate ideal solution sorting method (TopSISs), the optimal selection model of the volcanic gas reservoir development scheme based on the improved AHP- entropy method and TOPSIS is established. The effectiveness of the model is verified by the optimal selection of 8 decision development schemes for volcanic gas reservoirs in a certain block of Songliao Basin. The results show that the approximate degree of the eight decision schemes to the positive ideal scheme calculated by the established optimal selection model is 0.294 70.504 1 079 80.767 5N 0.316 5N 0.640770.621 3 and 0.254 6, respectively, according to the principle of minimum optimal distance between the decision scheme and the positive ideal point. The optimal scheme is the decision scheme 8. The optimal selection results can provide auxiliary reference for oil companies to make decisions, and have certain practical and theoretical significance.
