十屋油田低渗透油层测井识别技术

Logging Identification Technology in Low Permeability Reservoir in Shiwu Oilfield

针对十屋油田低渗透油层评价中存在的问题,通过对十屋油田营城3组及沙一段储层岩性、物性及试油情况进行分析,系统建立了各砂层组有效储层下限标准,并提出利用饱和度差值法和孔隙度差值法来识别评价十屋低渗透油气层。提供的计算参数和油气层结论可为油田开发提供参考依据。

For the problems in low permeability oil reservoir evaluation in Shiwu oilfield,The authors analyzed lithology,physical properties,electrical properties,and test oil situation of the reservoirs of the Yingcheng Formation and the first member of the Shahe Formation,established the standards in identifing effective reservoir,and proposed to make use of saturation difference method and porosity difference method to identify the low permeability reservoir in Shiwu oilfield,the good practical application for the oil field development provided an important basis for decision making and reference.
