摘要
目的油气藏一般具有地质构造复杂的特点,在开发初期,由于获取的油气藏的信息量较少,使许多油藏工程方法的应用受到限制,而物质平衡法具有不考虑复杂的地下渗流特征,只需较少的地质资料,流体物性测试资料和有关的生产动态资料和信息,计算方法和程序比较简单的特点。文章对各种驱动方式下的物质平衡方程进行了分解,并利用线性处理方法对所建立的物质平衡方程进行了回归,结果可准确地确定油气藏的储量、油气井的合理产能,并对油气藏进行动态分析及预测,这对编制合理的开发方案,更加高效合理地开发油气藏有着非常重要的理论意义和现实意义。
Oil (gas) reservoir has a characteristic of complex geologic structure. In initial production stage, the application of some reservoir engineering methods is confined for insufficient information. The material balance method need not take complex underground seepage characteristics into account, only need fewer geologic information, fluid physical testing data and some production performance information, and its calculation method and program is simple. So, this paper had built the material balance equation suited for various type of reservoir and carried out linear regression, the calculation result could determine reservoir reserves and oil well productivity veraciously, and carry out dynamic analysis and prediction to reservoir.
