| 摘 要： | 以某低渗透油藏为对象,首先在数据挖掘的基础上制定了低渗透油藏注CO_2驱筛选标准.基于模糊综合评价法,建立了适用于低渗透油藏CO_2驱适宜度评价的模糊综合评价模型,并运用该模型对目标油藏注CO_2的适宜度进行了评价.计算结果表明目标油藏注气驱开发适应性较好.评价过程有效地降低了直接进行注气开发的风险,为之后低渗透油藏注气开发提供了技术和经济上的指导.

| Abstract: | Based on the existing screening criteria of gas injection reservoirs in the literature,fuzzy integrated evaluation is employed to develop a new screening criteria model for judgments of gas injections in the low-permeability reservoir.Results show that CO2 injection is suggested for the development of the target reservoir.This process effectively reduces risks of direct gas injections without taking essential evaluations,and also provides guidance to the technical and economic aspects regarding to the development of the low permeability reservoir. |
