摘要
本文提出利用地震信息预测油气富集区的理想距离法：规格化处理地震信息并加权，求出理想点；求取被评价点到理想点的空间相对距离；用最优化理论中的单纯形法确定最佳权向量及被评价点的分类标准；预测油气富集区。在齐家南─古龙北地区用该方法预测葡萄花油层的含油气性，预测的工业油流区与探明储量区基本吻合，已知区的回报率达８５．７％，扩大了工业油流区范围，还预测了５个新的工业油流区块。
This paper suggests an ideal distance method to predict oil and gas accumulation region bymeans of seismic information, which is normalized and weighted to find out an ideal point, thespace distance between the points is evaluated and the ideal point is determined then; the singular shape method in the optimyzation theory is used to determine the optimum weightedvector and the classified standard of the point is evaluated to predict oil and gas accumulationregion.The method is used to evaluate the oil and gas abundance of oil and gas in Putaohuaformation in a district south of Qijia and north of Gulong.The results of prediction agreewith the proven area basically with an rate of 85.7%. The area with commercial oil production is extented and 5 new prospective areas are predicted.
