摘要

文中油田开发已经有20 多年的历史,含水、采出程度都较高,稳产形势十分严峻,以往定性的剩余油研究已不能满足油田开发的需要,在油田井网密度较大的情况下,加上多年积累的生产资料,为建立定量的地质模型及应用数值模拟定量预测剩余油提供必要的物质基础。以油藏精细描述和定量地质模型为基础,结合油藏生产动态、新钻调整井水淹层解释及油井产液剖面、注水井吸水剖面、压力监测等动态监测资料分析为依据,对文留油田文中地区的生产动态进行综合分析和评价。利用动态分析法定性—半定量地研究剩余油的分布状况,采用油藏数值模拟法全面应用油藏各项静态和生产动态资料,经历史拟合后,模拟得到油藏地下剩余油较精确的定量分布并对将来生产动态给以预测,指导油田的方案部署和剩余油挖潜。

Abstract

Wenzhong oilfield had a development history over 20 years.

It faces production decrease. The traditional method can not meet

the need of development. Quatitative reseach on residual oil is

necessary in this phase ,and well density is high enough to use

numerical simulation. Years of production data also provide

physical foundation it. Therefore , analyze and assess the

production performance of wenzhong oilfield on the bases of

accurate reservoir characterization and quatified geological

model. Moreover , we correct the geology model according to

production ,data from new well ,injection profile ,pressure testing

point out empirically and even quatitatively in some degree the

distribution of residual oil. reservoir numeric simulation pays an

vital role in forecast of residual oil.We can predict the production

performance of oilfield in advance ,and make development plan to

recovery residual oil.
