气驱特征曲线在油田开发中的应用

气顶油藏的开发中占有很大的比例，然而利用油藏工程方法研究气顶油藏的开采动态要比油藏开发少得多。本文提出了利用气驱特征曲线方法较好的解决了气顶油藏靠天然能量开发过程中的３个问题。从而提出利用气驱特征曲线方法研究油藏藏开采动态的一种新方法。这３个问题是：（１）气驱特征曲线的建立；（２）利用该方法计算油田储量；（３）分析油藏开采动态并进行预测。

APPLICATION OF GAS DRIVE CHARACTERISTICS CURVE IN OIL FIELD DEVELOPMENT

There are large number of oil fields developed under gas cap drive in operation currently,however, much less studies on the reservoir behavior of such oil fields have been carried. Thispaper suggests a technique of solving three problems in reservoir performance by means ofgas drive characteristic curve, and thus, a new technique is presented. The three problemsare: (1) establishment of a gas drive characteristic curve, (2) estimation of oil reserves,(3) reservoir performance analysis and prediction.
