卫2块气顶底水油藏描述

Characterization of Block Wei 2 Reservoir with Gas-cap and Bottom-water

针对卫城油田卫 2块油藏的特点 ,以建立三维精细地质模型为基础 ,应用 Landmark公司的 VIP4 .0油藏数值模拟软件包 ,对油藏中油气水三相的非混相流动状态进行了数值模拟。模拟结果表明 ,剩余油主要分布在 :1注采系统局部不完善区 ;2未注水的弹性开采区 ;3未受油水井控制的储量损失区。

In consideration of the reservoir characteristics of Block Wei 2 in Weicheng Oilfield, a numerical simulation is made on three phase immiscible flowing of oil, gas and water in reservoir by using Landmark VI P4 0 software package of reservoir simulation on the basis of building a 3D precision geologic model The result of simulation indicates that remaining oil is mainly distributed to:①local imperfection area of injection production system;②flexible producing area without injection;③reserve loss area uncontrolled by oil and water well Based on the remaining oil distribution, improvement programme is implemented with a good result
