X油田中高渗强边水油藏有效控水研究

Study on effective water control of X oilfield middle-high permeability strong edge water reservoir

X断块为一中高渗层状断垒构造油藏,目前断块采取天然能量开发,能量充足。从生产动态看,断块目前主要存在问题是随着含水上升,单井产油量明显下降,最终造成断块递减逐年增大。针对上述问题,本文从单井、单砂体出发,分别对三个主力油组提出了不同的控水稳油对策,最终确保断块有效可持续开发。

X block as a medium of high permeability layer base structure reservoir, to block it natural energy development,energy is enough. From the production performance, fault block at present the main problem is with water cut rise, single well oil production decreasing obviously, resulting in fault block of diminishing increases year by year. According to the above problem, this article embarks from the single well, single sand body, respectively the three main oil group different water control stabilizing oil countermeasure is put forward, and finally to ensure effective sustainable development block.
