鲁克沁三叠系稠油储层含油水性及有效性分析

Oil-water Property and Availability Analysis of Triassic Heavy-oil Reservoir in Lukeqing Area

利用荧光显微镜技术分析手段,通过对稠油储层不同种类的含油特征的研究,从沥青的组成、分布状况及其与围岩的关系等方面着手,结合钻井取心岩心岩矿特征、录测井等资料的分析,总结出稠油储层中孔隙的稠油层、含水层和混合稠油层等的荧光特征及含油有效性的分布规律,并对稠油储层的有效下限进行了分析探讨,为稠油油田制定开发方案提供了坚实的微观依据。该项研究的积极意义在于为荧光显微镜技术的进一步开展提供借鉴。

By using fluorescent microscopic technology, asphalt component, distribution situation and relation between asphalt and surrounding rock are researched based on the study of petroliferous characteristic of various heavy oil reservoirs. And integrated analysis of coring, core characteristic and logging, distribution law of fluorescent characteristic and petroliferous availability in porous heavy oil layer, water bearing stratum and mixed heavy oil layer has been summarized and effective lower limit of heavy oil reservoir is analyzed, which provided a substantial microcosmic base for making development program of heavy oil oilfield. The study is of positive significance for providing reference to fluorescent microscopic technology.
