摘要:
复杂断块油藏进入高含水开发阶段后,夹层控制剩余油是重要的挖潜对象。复杂断块油藏夹层分布规律性差,剩余油分布更加复杂。以江苏油田G6断块某厚层砂体为例,综合运用岩心观察、扫描电镜等资料,研究了储层夹层的成因、识别方法、分布特征以及对剩余油分布的控制作用,并提出了相适应的挖潜技术方向。研究表明:G6断块夹层以泥质夹层为主; 基于不同夹层测井响应差异,建立了夹层识别图版,绘制了夹层分布图,确定了G6断块夹层分布特征,揭示了夹层对剩余油分布影响规律:纵向上夹层加剧了剩余油分布的差异性,平面上剩余油多富集于夹层发育位置,其中分布频率在0.15层/m以上井区为重点挖潜对象; 针对夹层控制剩余油,提出了补孔、调剖及间歇性注水三种挖潜措施。本研究对同类油田高含水开发阶段剩余油挖潜有一定参考价值。
Abstract:
After the complex fault-block reservoir is entered into high water-cut stage, remaining oil controlled by interlayer is an important potential tapping target. There is poor distribution of interlayer and more complex remaining oil distribution in the complex fault-block reservoirs. A certain thick sandbody of G6 fault block in Jiangsu Oilfield was taken as a case study. Combined with core observation, scanning electron microscope and other data, it was carried out studies on the formation cause, identification methods, distribution characteristics of reservoir interlayer and its effect on remaining oil distribution. And then it was proposed the corresponding technological direction of tapping potential. Research results show that the interlayer of G6 fault block is mainly muddy intercalation. Based on the difference of logging response among various interlayers, the identification chart and distribution map of interlayers were established. And then it was determined the distribution characteristics of interlayer in G6 fault block, indicating the effect rule of interlayer on remaining oil distribution. In the vertical layer, the difference of remaining oil distribution is aggravated by the interlayer. In the plane, the remaining oil is enriched in the development position of the interlayer, where the well area with the distribution frequency of above 0.15 layer /m should be the key tapping target. For the remaining oil controlled by interlayer, it was proposed three measures of tapping potential including perforation adding, profile control and intermittent water injection. This study has a certain reference value for tapping remaining oil at high water-cut stage of similar oilfields.
