摘要
以苏北盆地低孔低渗储层为研究对象,以提高单层测井解释符合率为目标,结合前人关于储层形成机理、沉积微相的研究成果,运用600多口井的相关数据,通过地质与测井的有效结合,分区块、分层段进行了测井综合评价研究。研究内容包括储层区域分类,有效孔隙度、渗透率、饱和度等解释模型的建立等。研究形成的苏北盆地低孔低渗储层解释方法,使储层参数定量计算结果与岩心分析结果的相对误差达到行业标准。通过122口新井验证,储层单层测井解释符合率在83%以上。
Comprehensive logging evaluation was conducted by blocks and intervals for the low porosity and permeability reservoir in Subei Basin by using related data from over 600 wells and combining geological and logging approaches based on previous research results on reservoir formation mechanism and sedimentary microfacies in order to improve the coincidence rate of individual layer log interpretation. The research contents include regional classification and establishing interpretation models of effective porosity,per-meability and saturation. The interpretation method developed for the low porosity and permeability reservoir in Subei Basin has a relative error between calculated reservoir parameters and core analysis results conforming to the industry standard. It has been verified by 122 newly drilled wells that the coincidence rate of well log interpretation is above 83%.
