摘要
大庆外围油田经过27年优选开发，未开发储量和潜力主要为特低渗透、特低丰度和薄互层零散砂岩的岩性油藏。在分析外围油田地质特征的基础上，系统总结了地质-测井-地震多学科综合油藏描述与评价优选技术，包括低阻含钙薄互层油水同层测井解释技术、薄互层零散砂体地震分频分析预测技术、薄层零散砂体地震精细反演预测技术、低渗透储层裂缝描述与预测技术、复杂岩性油藏滚动评价优选技术，提出了综合油藏描述与评价优选技术下一步发展方向。该技术对同类型油田评价开发具有重要的指导意义。
After 27 years＇optimized development in Daqing Oilfield, the undeveloped reserves and potentialities are mainly in ultra-low permeability reservoirs, ultra-low abundance reservoirs and the lithologic reservoirs with thin interbeded stray sandstone. Based on the geological analysis of peripheral oilfield, this paper systematically conclu- ded the multidisciplinary （geology-logging-seismic） reservoir description, evaluation and optimization technology, including the log interpretation technology for low-resistivity calcareous thin interbeded oil-water layer, the predic- tion technology by Spec Decomp analysis for the thin interbeded stray sand-body, the fine seismic inversion predic- tion technology for the thin interbeded stray sand-body, the fracture description and prediction technology for low- permeability reservoir, and the rolling evaluation and optimization technology for complex lithologic reservoir. The next development direction of the integral reservoir description, evaluation and optimization technology was proposed, which is of important guiding significance to the evaluation and development of analogous oilfields.
