摘　　要：方斗山构造带位川东高陡构造区,地腹形态复杂,地层倾角大。由于构造条件复杂,地震解释难度大,造成本区钻探程度极低。本文结合现有的钻井及地震资料分析了方斗山构造带的构造特征及地层特征,绘制了石炭系及黄龙组地层等值线图,描述了其构造演化过程,分析了石柱古隆起对该区油气聚集的影响,最后根据现有分析选择中台子构造为该区域下步有利勘探目标。Fangdoushan tectonic belt situates in east Sichuan Basin where subterranean forms are complicated and the formation dip angle is large. The complex structures and the difficuhy of seismic explain of his area results from low degree of exploration. In this paper,the drilling and seismic data analysis of the structural characteristics and stratum characteristics. The authors draw the Huanglong Formation contour map , describe the structural evolution process, analyze the paleo uplift＇s effect to oil and gas accumulation. At last, the authors choose the the potential exploration targets of the area.
