川南地区气田水防垢方法应用

APPLICATION OF ANTISCALING METHOD OF GAS FIELD WATER IN SOUTH SICHUAN AREA

川南地区是以下二叠统气藏为主的气区，产大量的气田水，气田水结垢是生产中的一大难题。通过对川南气田水水质、结垢成因、结垢趋势的研究，提出采用密闭排水防垢方法。经矿场试验证明，该技术既经济又可降低工人劳动强度，防垢效果也较理想。

South Sichuan gas area with a lot of gas field water takes Lower Permian Series gas reservoir as main body.Gas field water scaling is a difficult problem in production.The antiscaling method of sealed drainage is proposed out by studying the gas field water components, scaling origin and scaling tendency.It is proved by field test that the method is economical, able to reduce labor intensity and to get a good result.
