海上N油田储层参数精细建模方法

Fine modeling method of reservoir parameters in offshore N field

当前油气勘探重心已实现从常规油气藏向非常规油气藏的转变,海上N油田在非常规油气藏中属典型的低孔低渗储层,这类储层受到沉积、成岩多种因素影响,储层非均值性较强,依据传统单一的储层静态测井孔、渗、饱参数,与实际测试结果相比符合率不理想。本文采用区域综合分析方法,对目标区的相关资料进行了统计分析和重解释,解释结果与岩心分析实验标定结果对应较好,结果可信度高。

At present,the focus of oil and gas exploration has realized the transformation from conventional oil and gas reservoirs to unconventional oil and gas reservoirs,and offshore N oilfield is a typical low-porous and lowpermeability reservoir in unconventional oil and gas reservoirs,which is affected by various factors of sedimentation and diagenesis,and the reservoir heterogeneity is strong,and the compliance rate is not ideal compared with the actual test results according to the traditional single reservoir static logging hole,seepage and saturation parameters.In this paper,the regional comprehensive analysis method is used to statistically analyze and reinterpret the relevant data in the target area,and the interpretation results correspond well to the calibration results of core analysis experiments,and the results have high credibility.
