Mining method of carbonate rock sulfur-bearing gas reservoir

Abstract

The invention provides a method for exploiting a sulfur-containing gas reservoir of carbonate rocks and relates to the technical field of exploiting of the sulfur-containing gas reservoir. According to the exploiting method, a dynamic distribution curve of sulfur deposition saturability of the sulfur-containing gas reservoir is predicted firstly, and the sulfur-containing gas reservoir is exploited according to the dynamic distribution curve of sulfur deposition saturability. The technical problem that shutdown often happens in the actual exploiting process of the sulfur-containing gas reservoir due to the fact that the sulfur solubility is difficult to calculate and sulfur deposition in the exploiting process cannot be reflected really when the sulfur-containing gas reservoir is exploitedis solved with the exploiting method, and the purpose that smooth exploiting of the sulfur-containing gas reservoir can be effectively guaranteed is achieved.

Description

technical field [0001] The invention relates to the field of mining sulfur-containing gas reservoirs, in particular to a method for mining sulfur-containing gas reservoirs in carbonate rocks. Background technique [0002] With the continuous in-depth exploration and development of sour gas reservoirs, the accompanying problems have also received extensive attention. During the development of sour gas reservoirs, H 2 S corrosion, high toxicity and sulfur deposition are the three major problems that need to be paid attention to. For gas reservoir engineers, the deposition of elemental sulfur is the core problem. The deposition of elemental sulfur (elemental sulfur) in the reservoir, bottom hole or tubing will lead to a decrease in gas well production or even stop production directly. Therefore, accurate prediction of elemental sulfur solubility is one of the problems that must be solved first in the development of sour gas reservoirs. [0003] During the exploitation of sou...
