目前喇北东块一区已进入特高含水期开发阶段,剩余油分散,挖潜难度越来越大。为了进一步改善特高含水期水驱开发效果,我们以注好水、注够水,提高有效注水、强化提液挖潜、增加可采储量为原则,以精细调整、精细挖潜为手段,不断拓宽特高含水期控水挖潜新途径,努力控制产量递减与含水上升速度,不断提高水驱开发效果。本文针对水驱开发中存在的问题,应用精细油藏研究成果,分析水驱井的开采状况,分析剩余油分布状况,积极寻找剩余油富集区。通过对水井采取压裂、细分、测调等措施,改善注水井的注水状况;同时对油井采取补孔、压裂等措施,进行综合调整,有效挖潜剩余油,从而改善特高含水期水驱开发效果。
At present, a zone of the eastern block of La north has entered the stage of development of the special high water cut stage, and the remaining oil is dispersed and the potential for tapping the potential is getting more and more difficult. In order to further improve the development effect of waterflooding during the ultra-high water-cut period, we focus on the principles of fine water injection, enough water injection, effective water injection, enhanced taping potential and increased recoverable reserves, with fine adjustment and careful tapping of potential, High water cut period control water tapping new ways, efforts to control the production decline and rising water rates, and continuously improve the development of waterflooding effect. In this paper, according to the existing problems in the development of waterflooding, applying the research results of fine reservoirs, analyzing the exploitation conditions of water flooding wells, analyzing the distribution of remaining oil and actively looking for the remaining oil enrichment areas. Through the fracturing, subdivision, measurement and other measures to improve the well water injection wells; at the same time the wells to take the hole, fracturing and other measures to make comprehensive adjustments to effectively tap residual oil, thereby improving the ultra-high water-cut period of water Drive development effect.
