基于数据挖掘的低品位油藏经营评价指标分析

The Analysis of Evaluation Index of Low-Grade Reservoir Operation Based on Data Mining

摘要: 本文针对高效经营未开发低品位油藏是我国石油行业即将面临的迫切任务情况，综合使用油藏经营思想、经济评价的分析方法和多种数据挖掘方法，提出了建立未开发低品位不同油藏经营效益评价的指标体系方法。通过大量实例统计研究，确定了低渗透和稠油未开发低品位油藏经营效益评价的指标体系。建立的未开发低品位不同类型油藏经营效益评价的指标体系可为油田企业评价该类油藏的经营效益，进而制定经营这些油藏的最佳方案奠定基础。

Abstract: With the situation which operating efficiently untapped low-grade reservoirs is a urgent mission for our petroleum industry to execute, this paper presents the method to construct index system on benefit evaluation of untapped low-grade reservoir operation by using comprehensively the idea of reservoir operation, the analysis method of economic evaluation and multiple methods of data mining. Through a lot of case studies, the benefit evaluation index systems of untapped low- grade low permeable and heavy oil reservoirs are determined. These index systems may establish the foundation for oilfield enterprises to evaluate the operational benefit of untapped low-grade low permeable and heavy oil reservoirs and to formulate the optimal scheme of operating these reservoirs.
