| 摘 要： | 交联聚合物微球的颗粒粒径和溶胀性能是影响调驱效果的主要因素.为提高交联聚合物微球在高含水、强非均质性油藏深部调驱中的应用效果,通过粒径实验、岩心驱替实验等对交联聚合物微球分散体系的性能进行了评价.结果表明:交联聚合物微球在60℃条件下、用孤岛回注污水溶胀10d后,粒径中值增大了34倍;交联聚合物微球分散体系的单管封堵率大于92%,双管岩心驱油实验提高采收率大于11%,交联聚合物微球分散体系完全能够满足孤岛油田高渗透油藏深部调驱的要求.在GD2-24斜516井组实施了交联聚合物微球分散体系深部调驱现场试验,注水井油压上升了2.9MPa,对应一线油井见效高峰期含水率下降了5.6%,单井平均增产原油5t/d.表明交联聚合物微球深部调驱是改善注水剖面和降低油井含水率的有效方法.

| Abstract: | The dominant factors of deep profile control and displacement are particle size and swelling ability of crosslinked polymer micro-ball. In order to improve the application effect of the deep profile control and displacement of crosslinked polymer micro-ball in high water cut reservoir which is inhomogeneous seriously, the a-daptability of the micro-ball disperse system was evaluated by experiments of particle size analysis and core displacement. The result shows when the micro-balls prepared by Gudao waste ... |
