孤东油田稠油单元九区开发20多年,经历了冷采阶段、蒸汽吞吐试采阶段和吞吐+汽驱阶段,矛盾和问题越来越多,剩余油主要集中在主力层边部和非主力油层等难动用区域,分布更加零散,如何挖掘上述剩余油是我们探讨的问题。文章通过精细地质研究、优化水平井井位设计、实施工艺配套等措施,对九区薄层实施水平井挖潜。与直井对比,水平井具有日产油能力高、含水低的特点,取得了较好的效果。
After more than 20 years of development in the nine districts of Gudong Oilfield heavy oil unit, it experienced more and more contradictions and problems in the cold mining stage, the steam huff and puff test stage, the huff and puff stage, and the remaining oil mainly concentrated in the main and non-main Oil and other difficult-to-use areas, the distribution is more fragmented, how to tap the remaining oil is our discussion of the issue. By fine geological research, optimization of horizontal well location design, implementation of technology and other measures, the nine districts of the horizontal wells to tap the potential. Compared with vertical wells, horizontal wells have the characteristics of high daily oil production capacity and low water content, and achieved good results.
