The Summary of High Sulfur Fractured Gas Reservoir´s Exploitation Features

Compared with conventional gas reservoir, the complexity and particularity of geologic characteristic and exploitation feature in high sulfur gas reservoir leads to its development technique difficulty, strictly required safety condition and high cost of exploitation. There are some problems in the procedure of exploitation, such as the phenomenon of sulfur deposition in layer and wellbore, the phenomenon of fracture closure, the hyper toxicity of hydrogen sulfur, strong corrosiveness, the formation of hydrate in wellbore, the phenomenon that the component concentration of hydrogen sulfur in produced gas is move upward as well as the abnormality of wellhead pressure after the gas well is shut in. Furthermore, these problems have great effect on regular production of high sulfur fractured gas reservoir.
