摘要:

通过对大庆油田萨尔图中部开发区北一二排西部上返二类油层聚合物驱前调剖剂用量计算方法、计算公式进行推导,确定了调剖剂用量、经济效益计算模型,并以此为基础对目的区块的调剖深度、经济效益进行计算机模拟计算,并将计算结果与主力油层已经取得的最佳调剖深度经验认识进行对比分析,并考虑到矿场应用的便利性最终确定大庆油田萨中开发区二类油层在175m井距下预交联体膨颗粒调剖剂最佳经济效益调剖深度为60m。

Abstract:

Through practice of lifting up polymer flooding target to underproductive performed in west of row 1 and 2, the developing area of central Sartu, Daqing oilfield, as well as profile modifying agent dosage calculation before polymer flooding and formula deduction, the applied profile modifying agent dosage and its economics calculation model are determined. On the basis of above practice, simulated calculations of the target formation profile modification depth and its economics are performed. After the comparison between the simulated result and the optimal profile modification depth obtained in the key productive formations, it is finally determined that, with a well spacing of 175 meters, and the given profile modifying agent of expandable particle crosslinker, the most effective profile modification depth in underproductive formations is 60 meters.

Key words: profile modification, depth, polymer flooding, under productive formations, Daqing oilfield
