苏里格低渗储层含水气井产水量计算方法研究

Research on the water-bearing gas well's water yield calculation method of low permeability reservoir in Sulige gasfield

苏里格西区,部分气井进入生产中后期,出现了含水较高的现象,且不能确定单井的产液量,对气井管理造成较大困难。为进一步提高气井综合开发水平,现通过气液两相计量结果,结合试气资料,推导出符合苏里格西区气井产水量的计算公式,并确定其符合系数,最后对该公式进行效果评价。

In western Sulige gasfield,some gas wells began to produce water in the middle-late period of exploitation,and the water yield of wells were unable to determine,which brings great difficulty to the gas well management.In order to improve the comprehensive develop- ment of gas wells, the article uses the data from gas-liquid two-phase flow measurement and gas production test,derives the calculation formula and determines the coefficient of coinci- dence which applies to water yield of gas wells in western Sulige gasfield,and then evaluates the effect of the formula.
