| 摘 要： | 野外调查和钻探工作证实库车坳陷北部提克买克地区地表出露大量的侏罗系克孜勒努尔组油砂,累计厚度达7.5m；钻井油砂累计厚度达9.27m,最大单层厚度3.5m,埋深在40m以浅。油砂主要赋存在中侏罗统克孜勒努尔组岩屑砂岩孔隙和裂隙之中。该油砂矿藏是在喜马拉雅造山运动的作用下,经构造抬升运移至侏罗系储层中,并遭受水洗氧化和生物降解形成,属于抬升运移型成藏模式。经初步资源量估算,研究区油砂油地质资源量为17.88万t。

| Abstract: | Field investigation and drilling confirm that oil sand of Jurassic Kezilenuer formation exposed on Tikemaike area, where is situated in the northern Kuqa depression, are 7.5m thick in total. Drilling data confirm accumulated oil sand of 9.27m, with maximum thickness of 3.5m for single layer. The maximum burial depth for oil sand is 40m. The secondary pores and cracks are developed in reservoir sandstone in Jurassic Kezilenuer formation. Followed by tectonic deformations in Himalayan orogeny, oil reservoirs are uplifted and migrated to Jurassic sandstone. After washing oxidation and biodegradation, the reservoir formed surface oil sand. Oil accumulation model can be summarized as uplifting related migration and accumulation. The preliminary oil sand resources is estimated as 177.88×104t. |
