摘 要关键词；；； Abstract Bottom water reservoir has a large proportion in our country and its reserves are also abundant . In addition to a large number of natural underground water reservoir, with the oil fields into the secondary recovery, water content gradually increased, more oil fields of the development characteristics continue to tend to the type of bottom water reservoir. To face domestic oil increasing water in general development situation, studying bottom water reservoir deeply becomes very meaningful. Based on the literature data access,This article analysis the bottom water reservoir of the mining process, and the main study the mechanism of bottom water coning. For the bottom water reservoir capacity calculation, the horizontal wells of three-dimensional flow field similar to the decomposition of both internal and external flow field, combined with the equivalent flow resistance method to get the critical yield is calculated. According to bottom water coning mechanism, this article study the bottom water reservoir water control theory. Control theory is a reasonable basis for the production of pressure, a reasonable yield, the extent reasonable shot open. Horizontal wells at the end of the water reservoirs, and underground horizontal well to make certain treatment, including variable density perforating, sealing packer, etc., this method can controlled bottom water coning well. In addition, underground oil-water mining methods used to control the production of pressure in the oil-water interface of an artificial barrier can effectively control the bottom water coning. 朗读 显示对应的拉丁字符的拼音 ? 字典 朗Key words: bottom water reservoir; productivity calculation; horizontal well; control of water coning朗读显示对应的拉丁字符的拼音?字朗朗显示对应的拉丁字符的拼? 字典 第1章 概述 1 1.1 课题研究的目的和意义 1 1.2底水油藏的研究现状 1 1.3 研究的主要内容 2 第2章 底水油藏基础理论研究 3 2.1 底水油藏的概念 3 2.2 底水油藏的驱动规律 4 2.3 底水油藏的锥进机理 4 2.4 水平井在底水油藏中的应用 8 2.5 本章小结 10 第3章 底水油藏产能计算的研究 12 3.1 低渗透油藏压裂水平井产能计算新方法 12 3.2 底水油藏水平井的产能计算 19 第4章 底水油藏控水技术的研究 23 4.1 控制
