【摘要】 对塔里木盆地库车坳陷巴什基奇克地区油砂油抽提物成分分析表明该油砂油确实发生了一定程度的氧化与生物降解作用,油砂油的烃源岩的母质成分以侏罗纪时期淡水深湖相,且有机质来源以高等植物为主,有机质成熟度较高,且处于生烃高峰期。由于该地区石油成藏晚,后期构造运动强烈,使原有的油气藏受到破坏,油气溢出到地表形成油砂,具有良好的勘探前景。更多还原

【Abstract】 The analysis of the composition of the oil extraction from oil sand oil in the Bashijiqik area of the Kuqa Depression in the Tarim Basin China shows that the oil sands oil in this area does have a certain degree of oxidation and biodegradation.The parent material of the source rock in oil sand oil is of freshwater depth of lake during the Jurassic period,and the source of organic matter is mainly from higher plants.The mature of organic matter is higher,and is at the peak of hydrocarbon generation.Due to the strong late and late tectonic movement of the oil accumulation in the area,the original oil and gas reservoirs are damaged,the oil and gas spill into the surface of the ground and form oil sand,which has good prospect of exploration.更多还原
