摘要
适度出砂是通过优化产量和油井的产能在防砂生产和出砂生产之间确定最优的生产策略。适度出砂对储层物性有很大影响。以渤海胶结疏松的稠油油藏为例,提出了适度出砂提高单井产量的开采方式,并开展了室内实验研究。在调研国内外出砂模拟实验的基础上,利用现有的实验装置,以适度出砂原理为理论基础,与现场实际生产相结合,开展了人造岩芯制作,采用筛析法和直接出地层砂法进行了适度出砂对储层物性影响的室内实验研究。对渤海稠油油藏出砂油井的科学生产和管理具有一定的指导意义。
Through optimizing output and productivity,reasonable sand production exploitation decides optimal production measure between sand prevention and sand production.Reasonable sand production has big influence on physical properties of reservoir.In this paper,Bohai loose heavy oil reservoirs are taken as an example,some exploitation methods which improve the single well production with reasonable sanding are put forward,and corresponding experimental researches carried on.Based on investigation of simulating experiment about sand production at home and abroad,by using existed experiment device,man-made-cores are made,and laboratory research on the influence of proper sand production on formation physical property is conducted by using screen analysis and direct sand production.The researches are based on the proper sand production theory.The result can guide scientific production and administration in Bohai heavy oil reservoirs.
