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间题。根据火山岩气蔗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),与摘权法和遇近于理想期排序法(TOPSIS)相结合,建立了基于改进的AHP-权法和TOPSIS的火山岩气截开发方案优选模型,并以松辽金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个决策方案距高正理想方案的接近程度分别为0.2947,0.5041,0.6798,0.7675,0.3165,0.6407,0.6213和0.2546,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 choose the optimal program for volcanic gas reservoir development economically is an urgent problem to be solved. Ac-cording to the construction principle of the indexes of volcanic gas reservoir development program optimization, 7 optimum indexes of devel-opment program are determined, By using the improved analytical hierarchy process (AHP) and combined with entropy weight method and the technique for order preference by similarity to ideal solution (TOPSIS), an improved AHP-entropy weight & TOPSIS-based model for volcanic gas reservoir development program optimization is established and its validity has been verified by a case study of optimization for 8 volcanic gas reservoir development programs in a block of Songliao basin. The results show that the approximation degrees of each pro-gram are 0.2947, 0.5041, 0.6798, 0.7675, 0.3165, 0.6407, 0.6213 and 0.2546, respectively. Based on the optimal selection principle, it is considered that the optimal solution is the program No.8. The optimization result could provide references for decision making in oilfields, which has some practical and theoretical significance.

火山岩气藏开发方案的优选研究,是一项非常复杂的系统性工作-。随着中国天然气开采工作的进一步开展,火山岩气藏开发得到越来越多的重视,火山岩气藏因其岩石类型多、岩性复杂、岩性岩相变化快、储集层微裂缝发育、物性差、非均质性强等特点,开发难度非常大。
