吐哈三塘湖油田实施井网加密以来,采收率得到明显提升。截至2012年8月26日,三塘湖油田有23口加密井投入生产,累计产油1.39×104t,为油田完成计划原油产量做出贡献。三塘湖油田牛圈湖西山窑油藏属特低渗、低压、低流度、非均质性砂岩油藏,单井产量低,开发难度大。为有效动用低品位石油储量,科研人员2011年开始在三塘湖油田牛圈湖西山窑油藏开展井网加密研究,编制了《牛圈湖东区井网加密调整方案》,目的是通过井网加密调整,改变原来井距270m的菱形反九点法井网,形成
Turpan-Hami Santang Lake oilfield implementation of well network encryption since the recovery has been significantly improved. As of August 26, 2012, 23 infill wells in Santanghu Oilfield were put into production with a cumulative production volume of 1.39 × 104t, contributing to the completion of the planned crude oil production in the field. Xiantang kiln reservoir of Niuquan lake in Santanghu oil field belongs to the ultra-low permeability, low-pressure, low-flow and heterogeneous sandstone reservoirs. The output of single well is low and the development is difficult. In order to effectively use low-grade oil reserves, researchers began to carry out well network encryption research in Niu Shang Lake Xishan Kiln Reservoir in Santang Lake Oilfield in 2011 and prepared a plan for well network encryption adjustment in Niuhuanhu East Zone, Encryption adjustment, change the original well spacing of 270m rhombus anti-nine well pattern, formed
