塔里木盆地麦盖提斜坡西段成藏演化与有利勘探区域:以巴什托普油田为例
Hydrocarbon accumulation and favorable exploration areas in the western Maigaiti slope of Tarim Basin:A case study of Bashituopu oilfield
摘要
Abstract
The strata above and below the Middle Cambrian salt are the current research and exploration hotspots in the Maigaiti slope,Tarim Basin.The fracture characteristics were analyzed on the basis of seismic interpretation.Combined with the study results of structural geology,sedimentology and the thermal evolution history,the accumulation history of Bashituopu oilfield was analyzed.The Caledonian hydrocarbon migration and accumulation mainly occurred below the Cambrian salt at the western Maigaiti slope from north to south.Oil-gas migrated vertical upwards through northwestward strike-slip faults in the north and south sides of Bashituopu oilfield,and accumulated at the Bashituopu anticline forming an ancient oil reservoir in Hercynian Period.The present residual Bashituopu reservoir was formed in the Himalayan Period,besides the oil-gas adjusted from west to east,a small amount of lateral oil-gas filling.Both strike-slip fractures at the north and south sides of Bashituopu oilfield and traps under the Bashituopu main detachment faults are the favorable exploration objectives in the western segment of Maigaiti slope.关键词
