摘　　要：气井单井控制储量是气藏工程中一项重要的内容,而气井产水对单井控制储量具有明显的影响,准确计算产水气井单井控制储量在整个气田开发中有着重要意义。基于产水气井渗流特征,利用产水气藏分流率与日产气量、日产水量的关系,结合气、水两相相对渗透率曲线,得到产水气井单井控制储量计算的理论图版。通过将实际产水直井和水平井生产动态资料与单井控制储量理论图版进行拟合,获得产水直井与产水水平井单井控制储量,且对比发现,利用图版拟合法与物质平衡法、产量不稳定分析法、弹性二相法以及数值模拟法计算单井控制储量结果相对误差较小,表明新方法具有较好的实用性和可靠性,可以推广运用到产水气藏动态储量的计算。Individual gas well controlled reserves are the important contents in gas reservoir engineering, while the water producing gas wells possess obvious influences on the reserves, so the accurate calculation of the reservoirs presents an import significance during the development of the whole gasfield. Based on the seepage characteristics of the gas wells, by means of the relationships between the shunt rate of the gas reservoirs and daily gas and daily water productions, the individual vertical and horizontal water producing well controlled reserves are achieved with the help of the match between the actual production performance data of the above wells and the reserves theoretical chart, and moreover the contrasts show that by means of the following methods such as the chart matching, material balance, production instability analyzing, elastic two-phase and numerical simulating methods, the smaller relative errors of the calculated results of the reserves have achieved, thus the new methods prove much better practicability and reliability, and furthermore can be generalized into the gas reservoirs. calculation of the dynamic reserves of water-producing
