摘要

In order to investigate the inhibiting effect of ceiling shale barrier thickness on hydrocarbon loss effect caused by late tilting movements, the comprehensive analysis of main reservoir forming controlling-factors of reservoirs in Sangonghe Formation in Mobei area is conducted. It is thought that Xishan tip-tilting during the late stage of Neocene has a great secondary reformation effect on reservoirs in Sangonghe Formation of Mobei area in Junggar Basin. Through the overall analysis of prospecting and appraisal wells in this area and the quantitative simulation of local development well field, it is concluded that the ceiling shale barrier thickness required for industrial productivity formed by J₁s₂^1-2 reservoir in this area is 8～14 m, providing favorably technical supports for overall reservoir evaluation and development well pattern deployment in the area.
