Feixianguan 形成的水库更低在四川盆三叠纪是在中国的最深埋葬的碳酸盐水库与发达第二等的腐蚀洞,高数量焦化水库,最大的有效碳酸盐水库厚度。另外, Feixianguan 煤气的水库有 H2S 的最高的数量。研究发现在水库和 H2S 的形成之间有靠近的关系。在酸味液体和碳酸盐之间的相互的行动支持了形成第二等的碳酸盐洞。通过在氢硫化物,极大地增加的孔和渗透的浸透的水的答案的 Feixianguan 碳酸盐水库的样品的腐蚀的实验,孔增加了 2% ,渗透增加了将近二数量度,也,密度成为了光,它证实 H2S 的腐蚀和改革行动焦化。
The reservoir of Feixianguan Formation of the Lower Triassic in the Sichuan Basin is the deepest buried carbonate reservoir in China, with developed secondary corrosion holes, high quantities carbonate reservoir, maximum effective carbonate reservoir thickness. Also Feixianguan gas reservoir has the highest quantities of H2S. Research discovers that there are close relationships between the formation of reservoir and H2S. The mutual actions between acidity fluid and carbonate promoted the forming of secondary carbonate holes. Through the experiment of corrosion of the samples of Feixianguan carbonate reservoir in saturated aqueous solution of hydrogen sulfide, the porosity and permeability increased greatly, porosity increased 2% and permeability increased nearly two quantity degrees, also the density became light, which confirm the corrosion and reform actions of H2S to carbonate.
