文东油田连续气举优化配气数学模型建立及应用

Establishment and application of mathematic model of gas distribution optimization for continuous gas lift to Wendong oilfield.

针对连续气举在开发过程中出现的注入气利用效率低、综合效益差的问题 ,建立了供气能力有限时的优化配气数学模型 ,给出了解析法求解过程。文东油田现场试验表明 ,应用该技术可以实现连续气举井的合理配气 ,并提高油井产量 ,适合在油田推广应用。

In order to solve the problems of low utilization efficiency of injected gas and poor overall benefit in the process of continuous gas lift, mathematic model of gas distribution optimization at the limited gas supply capacity is built and the solving process of analytical solution method is given out. The field experiment in Wendong oilfield presents that this technique can be used to realize reasonable gas distribution among continuous gas lift wells, and raise the production of oil wells, so it is suitable to the extended application in the oilfield.
