摘要
对于地层胶结疏松、易出砂的稠油油藏 ,有防砂、排砂两种出砂管理方式。实践中采用的出砂管理模式取决于对两种模式的经济效益评价结果 ,文中提出了一套独立的防砂与排砂采油经济效益评价模型。影响防砂与排砂采油经济效益对比的敏感性因素主要有日初产量之差、作业成本之差、油价变化和油藏开采的递减率。根据影响因素的不同变化 。
To viscous oil reservoir with formation cementation and sanding,there are two sand removal management methods which are sand control and sand remwval.This paper proposes a set of independent economic benefit evaluating model of sand control and sand removal oil producing,presents the main sensible factors of influence economic benefit contrast on sand control and sand removal oil production that are the difference of initial production evevy day and operating cost,oil price chang and decline rate of reservoir production.On the basis of the different change of influence factors,in certain time,there are three cases happen that is good sand control benefit or good sand removal benefit or both benefit is alike.
