应用油藏工程方法确定天然水驱砂岩油藏水体

USING RESERVOIR ENGINEERING METHODS TO IDENTIFY SANDSTONE REsERVOIR WATER BODY DRIVEN BY NATURE WATER

本文根据天然水驱油藏特征,以物质平衡方程为基础,重点讨论了利用油田的地质参数和生产历史数据,应用油藏工程方法确定天然水驱砂岩油藏水体大小的方法。并以实际生产数据为例,分别采用了容积法、油藏数值模拟法和油藏工程法计算了红南油田白垩系油藏的水体大小及天然水驱采收率。从对比分析来看,应用油藏工程方法计算水体具有快速、准确和实用等优点。

According to the characters of natural water driving reservoir and the material balance equation, the paper mainly discusses the methods which identify size of the natural water driving sandstone reservoir by using the oil field geological parameters, historical production data and the reservoir engineering methods. The paper also takes the real productions data as an example and calculates the size of water body and natural water recovery rate in the cretaceous reservoir of Hongnan Oil Field by the reservoir numerical simulation and reservoir engineering methods. Through comparison, the reservoir engineering methods to identify the water body have the advantages such as fast speed, accurate, practical and so on.
