综合运用油藏工程法,动态分析法、物模、数模等方法,对处于蒸汽吞吐末期的洼38块沙三段油藏进行了蒸汽驱试验的可行性研究。通过该项研究确定蒸汽驱试验的合理开发层系、合理井网井距,并对试验的操作参数进行了优选。根据研究结果实施了6个井组的蒸汽驱试验,并见到了良好的效果。该项研究对同类油藏转换开发方式具有很好借鉴意义。 Comprehensively using reservoir engineering method, dynamic analysis method, physical model, numerical simulation and other methods, the feasibility study of steam flooding test was carried out on the No.38 Shahejie reservoir at the end of steam stimulation. Through this study, the rational development strata of steam flooding test and the well spacing of well were determined, and the operation parameters of the test were optimized. According to the research results, steam flooding test was carried out in 6 wells and good results were observed. This study is of great reference to the transformation and development of similar reservoirs.
