摘要
准噶尔盆地腹部彩南油田三工河组油藏经多年高速开发,有相当一批采油井已进入中、高含水期,而这部分井大多都只有单油层生产,无堵隔水、补层等措施可采取。根据油藏原油粘度小、流度大这一特点,在对逐井油水接触关系等方面进行深入研究后,确定了针对不同类型井的提液时机,适当提高单井的产液量,使其含水率基本稳定或下降,产油量明显上升,从而对整个油藏的稳产起了重要作用,同时也可提高这部分井的最终采收率,经济效益十分显著。
Following many-year high rapid development of Sangonghe formation in Cainan field,hinterland of Junggar basin,quite a number of production wells has been entered into the phase of medium-high water cut,and most wells have been yielded in sin gle layer without any measure of water plugging /resisting and supplementary layer recovery.This paper presents lifting timing for different types of wells which may increase fluid-yielding amount or IOR of single well and allow the water cut to be stabi -lized or dropped,while oil production to be increased effectively,based on features of low crude viscosity and high mobility as well as in-depth understanding of oil-water contact for each well.Through stable production of the whole reservoir,such a part of wells has been improved in ultimate recovery factor with very significant economic benefit.
