松辽盆地及外围油气资源基础地质调查——“十三五”阶段进展与未来工作展望

FOUNDATIONAL GEOLOGICAL SURVEY FOR OIL AND GAS RESOURCES IN SONGLIAO BASIN AND ITS PERIPHERY AREAS:Progress and Prospect

"十三五"期间,松辽盆地及外围油气地质调查以"开辟新区,探索新层系,联合攻关新类型、新领域,支撑百年大庆油田建设"为目标,紧密围绕"松辽盆地陆相页岩油、外围中小盆地、石炭-二叠系与中新元古界深层系"三大领域,取得了一系列发现与进展:一是以基质型页岩油为主攻方向,实施页岩油参数井获工业油流,揭示松辽盆地陆相页岩油巨大资源潜力;二是阜新盆地辽阜地2井获工业油流,实现久攻不克区勘探突破,为传统煤炭资源枯竭型城市转型发展提供资源保障;三是以深层系、非常规为指导思想,实施石炭-二叠系与中新元古界油气资源调查取得新进展.结合新形势、新需求,提出"全盆地、大地质、多资源"综合调查等下阶段工作方向.

The foundational geological survey for oil and gas in Songliao Basin and its periphery area aims at exploration of new areas,new strata,new types and new fields to support the century-long production of Daqing Oilfield.Investigations focus on the shale oil of continental facies,small-middle basins in surroundings and Carboniferous-Permian and Meso-Neoproterozoic formations.Significant progress has been achieved as follows:Industrial oil flow is obtained from parameter wells for matrix type of continental facies oil,revealing great potential resources of continental shale oil in Songliao Basin;The LFD2 well in Fuxin Basin yields industrial oil flow,which breaks through the difficulties of exploration in small-middle basins and will supply alternative resources for the resource-exhausted city;Achievement is made from foundational geological survey on deep formation and unconventional oil-gas in Carboniferous-Permian and Meso-Neoproterozoic strata.A comprehensive survey on the whole basin with all subjects for multiple resources is suggested to meet the new requirement and circumstances.
