深层稠油油藏水锥机理及HDCS实验研究
摘要
Abstract
Serious water coning problem and high water cut are seen in the development process of deep conventional heavy oil reservoirs in the Zhuangxie 139 block due to factors such as deep burial depth, highly deviated and extended reach wells and active edge/ bottom water. On the basis of preliminary fine geological study, the mechanism of bottom water coning is studied for heavy oil reservoirs, a conceptual model of horizontal well thermal recovery is build up, and HDCS (horizontal well, dissolver, carbon dioxide and steam) pilot test study is conducted based on laboratory experiment and numerical simulation. The research shows that for the heavy oil reservoirs with bottom water in the Zhuangxie 139 block under conditions of low oil recovery rate and high water cut, HDCS adjustment can effectively control bottom water coning, improve interwell and vertical reserves producing degree and recovery factor.关键词
