    摘要:

    萨北开发区北部过渡带四条带主要发育萨I组、萨Ⅱ组油层,研究区块中水平井B5-8-A53开采目的层SⅡ2 3层,SⅡ2 3层以下为油水同层或水层。目前阶段,水平井B5-8-A53的含水率有很大上升,水平井周围注水井点少,注采关系完善程度低,因此,水平井B5-8-A53周围注水井调整和油井转注问题仍需进一步研究。本文通过多种技术综合研究,加深对油层认识程度,完善油层精细地质建模方法,建立区块精细地质模型,精确描述层内隔层、描述层内非均质性;总结地质模型粗化方法,对精细模型进行粗化;再通过数值模拟研究,对区块含水率和水平井含水率、地质储量进行了拟合,并在剩余油分布研究的基础上,结合建立的地质模型选出打井的井位,并对打井方案进行预测和优化,找出水平井B5-8-A53开采效果最好的单井最佳方案,把单井最佳方案进行组合,优选出最佳的组合方案;为油田特高含水期的水平井B5-8-A53开发提供技术保证。

    Abstract:

    North transition belt of SaBei development area mainly develops the oil layer of SⅠ and SⅡ,horizontal well B5-8-A53 in this research area extracts the layer of SⅡ2 3,and under the layer of SⅡ2 3 is oil-water layer or water layer. At the present stage, water content of the horizontal well B5-8-A53 has risen severely, there are less injection wells around the horizontal well, and the improvement degree of injection-production relation is low, so we need to concern the problem of regulating injection well around B5-8-A53 and transforming injection for oil well. In this article, through a variety of technical synthetic study, we deepen our understanding of the reservior, perfect the method of the fine geologic modeling, establishe the block fine geologic model, descript heterogeneity of inner layer; summaring coarsening method of the geological model, and we need to match water content and geological reserve by reserching numerical simulation, and on the basis of the distribution of remaining oil, we sort out the well location combined with the established geological model and drilling plan is forecasted and optimized, and find out the best effect of single well optimal scheme of the horizontal well B5-8-A53. This can provide technical guarantee for the horizontal well B5-8-A53 in extra high aquifer stage.
