摘要
气藏多层合采,产量劈分是关键。如何利用各层地质参数及生产数据,对正确进行产量劈分以及进行气藏动态研究有重要的意义。常规方法利用气藏精细描述得到的有效厚度、有效渗透率等地质参数来分析,对于气藏压力却未考虑进去。文章在建立层间无串流双层模型的基础上,利用数值模拟的方法,从气藏压力、储层物性方面入手,考虑气藏非均质因素的影响,获得了多层气藏开发单井合采(分采)技术界限和界限方程。实例应用表明,采用该方法与测试符合程度较好,可为多层气藏开发层系划分提供正确的理论工具。
When the gas reservoir adopts commingling production, production compartment is the key. How to make use of geologic parameter and production data is important to carve up production and then to study the dynamics of gas reservoir. Conventional method always makes use of some geologic parameters such as net pay thickness, effective permeability, etc. to analyze, and seldom consider the pressure. Based on the bi--layer model without inter--flow between layers, using numerical simulation, according to thep- ressure and physical property of gas reservoirs, the equation is derived for multiple--zone（selective zone） production of multi--layered gas reservoir. Real case indicates that this new method can be used to production dividing of multi--layered gas reservoirs.
