| 摘 要： | 塔里木盆地柯 克亚古近系凝析气藏为超深(6400m)、超高压(128MPa、压力系数2.0)碳酸盐岩气藏,目前只有柯深102井在生产,该井于2003年8月7日投产,2003年12月28日开始产地层水，分析认为,水来自产层本身，有CaCl2型和Na2SO4,型两种类型。地质分析认为,前一种水是地层压力降低,超高压气藏泥质岩中的残余水被挤出而形成，而后一种是由于局部透镜状水体或边水侵入所致。

| Abstract: | The condensate gas reservoir of Paleogene in Kekeya field, Tarim basin, is a carbonate gas pool with super-depth of 6 400 m, superhigh pressure of 128 MPa and pressure coefficient of 2.0. At the present, only Keshen Well 102 is producing. This well was brought into production on Aug. 7, 2003, and began to yield reservoir water on Dec. 28, 2003. The reservoir water analysis provided CaCl2 and Na2SO4 types of water. This paper presents the former (CaCl2) is formed due to declining of the reservoir pressure and squeezing-out of residual water in shale of the superhigh pressure gas reservoir; the latter (Na2SO4) is due to intrusion of local lenticular water or edge water. |
