摘  要:川科1井是开拓川西坳陷海相勘探新领域具有重要战略意义的科学探索井兼区域探井,从地层、沉积环境、储层特征、烃源条件及盖层与保存条件等方面分析了川西坳陷下三叠统海相沉积成藏地质条件,在此基础上分析其勘探前景,指出坳陷西部边缘隐伏构造带、坳陷东南风化壳发育区以及坳陷东坡龙泉山构造带台内浅滩发育区为有利勘探区域,是下一步勘探的重点目标。As not only a scientific exploring well but also a regional exploration well,Chuanke 1 well is significant to pioneer the new exploration domain in marine in western Sichuan depression.In this paper,the reservoir-forming geological conditions of lower Triassic in the depression are studied in terms of stratigraphy,sedimentary environment,reservoir characteristics,source rock,caprock and preservation.And some exploration prospects are analyzed and obtained,including the buried structure belt in west margin of depression,the crust-developed area in southeastern depression and the shallow shoal-developed belt of Longquanshan structure zone in eastern depression.These three belts will become target for further exploration.
