塔中Ⅰ号坡折带勘探获得发现后,普遍认为塔里木盆地奥陶系坡折带具有优越的油气成藏条件,有可能直接控制了油气藏的分布。在这一思想的指导下,以坡折带为目标进行了一系列的研究工作。根据古城和罗西2个坡折带2口井钻获的烃类、包裹体等方面的分析证明了塔东地区坡折带原始油气藏已经遭受了破坏,后期油气充注类型明显不同,而成藏的差异性主要由烃源灶热演化差异、构造与断裂演化特征造成。古城坡折带北段和罗西坡折带西部台地前缘斜坡可能是下一步有利的油气勘探方向。
After the discovery of the Tazhong Ⅰ slope break belt exploration, it is generally accepted that the Ordovician slope break zone in the Tarim Basin has favorable hydrocarbon accumulation conditions and may directly control the distribution of oil and gas reservoirs. Under the guidance of this thought, a series of research work was carried out with the objective of slope break zone. According to the analysis of hydrocarbons and inclusions in the two slopes of the ancient city and Rossi, it is proved that the original reservoirs in the slope break zone of Tarong have been damaged and the types of hydrocarbon charge in the late stage are obviously different The differences of hydrocarbon accumulation are mainly caused by the differences in thermal evolution of hydrocarbon source stoves and the tectonic and fault evolution characteristics. The northern slope of the ancient city slope break and the slope of the western platform of the Lo Xibo break-up belt may be the favorable oil and gas exploration direction in the next step.
