| 摘 要： | 基于热力学平衡理论及库车盆地的实际,建立了该区地层水温度、压力条件下方解石溶解、白云石对方解石交代作用的热力学平衡条件,并根据地层水介质特征探讨了该区方解石溶解、白云石交代方解石的具体成岩反应状况,认为该区地层水条件下正进行着方解石溶蚀及白云石对方解石的交代作用,方解石的溶蚀是形成该区深层次生孔隙的根本因素。

| Abstract: | Based on the thermodynamics equilibrium theory and the reality in Kuqua depression,in this paper two diagenetic reactions in strata environment have been conducted,including the calcite dissolution and the replacement of dolomite to calcite.Furthermore,according to characteristics of oilfield water,the current situation of calcite dissolution and replacement of dolomite to calcite have been discussed.Lots of information implies that the two diagenetic reactions are carrying out in oilfield water;the dissolution of calcite cement is essential factor for the deep-buried secondary porosity anomaly in this area. |

| Keywords: | calcite dissolution dolomite replacement oilfield water Kela 2 gas field |
