利用遥感地质解译、土壤微量元素分析、土壤氡气测量以及野外露头观察等手段,在什邡湔氐地区识别出22条隐伏断层。它们按走向可分为北北西向、北东东向和近东西向3组。受关口断层推覆上升的影响,隐伏断层普遍具张扭性,活性较好,含水破碎带发育。从油气水文地球化学和地下水的活动规律来探讨该区断裂和盖层、地下水的配置关系,认为本区油气保存条件总体较差,但在单斜带局部区域寻找水动力圈闭气藏以及在云西—徐家场鼻状背斜上勘探深层气藏仍然有一定的潜力。
Using remote sensing geological interpretation, soil trace element analysis, soil radon measurement and field outcrop observation, 22 hidden faults were identified in the Shifang area. They can be divided according to the direction of North-West, North East and Near East-West 3 groups. Affected by the rise and fall of the gateway faults, the concealed faults are generally torsional, with good activity and water-bearing fractures. Based on the hydrogeochemical and groundwater activity rules, we discuss the disposition of fault, caprock and groundwater in this area. We think that the preservation conditions of oil and gas in this area are generally poor. However, looking for hydrodynamically trapped gas reservoirs in the partial area of the monoclinic, Deep exploration of deep gas reservoirs on the west-Xujiachang nose-like anticline still has some potential.
