多种测试方法在某聚表剂试验区中的应用分析

Application Analysis of Various Test Methods in a Certain Polymer Surfactant Test Area

大庆油田在萨尔图某试验区开展了二类油层聚合物+表面活性剂驱油试验。该试验区大量注入井吸水剖面测试资料与地质静态资料不相符。针对上述问题,通过多种测试资料解释和分析确定了高渗透层和验证封堵层,并制定了综合调整措施和效果评价测试方法。调整效果评价表明:措施调整后异常吸水层位得到了有效调整,油层动用程度得到了提高。

A test of sub-main layer polymer&surfactants flooding oil was carried out in a certain experimental area of Saertu in Daqing Oilfield.A large number of injection profile test data of the injection well in this experimental area were inconsistent with the static geological data.In order to solve the problem,high permeability formations and verification blocking formations were determined through the interpretation and analysis of various test data,and the comprehensive adjustment measures and effect evaluation test methods were developed.The evaluation of adjustment effect indicates that the abnormal water absorption level has been effectively adjusted after the measures were taken,and the utilization degree of oil reservoir has been improved.
