摘要： 目前已探明未动用储量评价的实质是新增投资的增量效益评价。常规经济评价方法无法指导各油田已探明未动用储量的开发投资决策,因此,提出了“微利开采”(增量效益评价)评价方法,并将已探明未动用储量在地质评价的基础上分为经济一类、经济二类、“微利开采’”一类、“微利开采”二类、“微利开采”暂无效益储量。还提出了采用先进、实用配套的工艺技术措施降低已探明未动用储量开发投资、成本的方法及经营管理模式,对各油田盘活已探明未动用储量资产具有深远的影响和现实意义。

Abstract: Volatile oil reservoirs are almost found everywhere,but few methods are available to quantitatively and quickly evaluate their regional extents resulted from oil/ gas segregation in bottom hole volatile oil zone for a production well. This article presents a procedure for calculating these regional radiuses based on fluid properties of oil/gas twophase flow and single phase flow regions, which provides necessary parameters for proper evaluation of volatile oil reservoir production.

Key words: 0il and gas reservoir, Two-phase flow, Bottom hole pressure, Saturation pressure, Flow
