【摘要】：针对桩西地区边底水油藏油井含水上升快、增产措施单一、剩余油挖潜难度大的问题,进行了边底水油藏径向钻孔配套堵水技术研究。文章介绍了径向钻孔技术的原理、优势、选井原则和参数优化原则,通过实验优选和评价了一种酚醛树脂交联冻胶堵剂的配方。实验结果表明,酚醛树脂交联冻胶堵剂具有较强的热稳定性和封堵性能。以桩1-G25井为例,介绍了径向钻孔参数设计、打隔板堵底水参数设计、施工管柱及工艺。现场试验表明,径向钻孔配套堵水技术能有效控制底水锥进,降低油井含水,挖潜井间剩余油,达到降液增油的目的,为下一步治理此类问题的油井提供了一种技术支撑。
[Abstract]:In order to solve the problems of high water cut in edge and bottom water reservoir, single measures to increase production and great difficulty in tapping remaining oil potential, the water plugging technology for radial drilling in edge and bottom water reservoir is studied in this paper. This paper introduces the principle, advantage, well selection principle and parameter optimization principle of radial drilling technology. The formula of a phenolic resin cross-linked gel plugging agent is optimized and evaluated through experiments. The results show that the crosslinked phenolic resin gel plugging agent has strong thermal stability and plugging performance. Taking pile 1-G25 well as an example, this paper introduces the design of radial drilling parameters, the design of bottom water parameters, the construction pipe string and the technology. The field test shows that the radial borehole matching water shutoff technology can effectively control the bottom water coning, reduce the water cut of the well, tap the remaining oil between wells, and achieve the purpose of reducing the fluid and increasing the oil production. It provides a kind of technical support for the next step to control the oil well of this kind of problems.
