摘要：

针对水平井在特殊的透镜状薄层底水油藏实际运用中与油层条件的适应性问题十分突出,国内外研究报道很少等问题。以新疆准噶尔盆地陆梁地区白垩系呼图壁河组低幅度、中高渗、透镜状薄层砂岩底水油藏为研究对象,采用地质、钻井、油藏工程、数值模拟等多种方法,结合水平井实际开采效果,研究认识了透镜状薄层底水油藏水平井长度与井筒压力损失、油层适应性、油层钻遇率和开发效果等多种因素之间的关系,提出了透镜体薄层底水油藏水平井合理长度的技术范围及界限,理论与实际应用相结合,研究结果具有较好的可靠性和可应用性,为类似底水油藏水平井开采研究与应用提供了方法和重要的技术参考依据。

Abstract:

The reasonable length of horizontal wells for lens-like thin-layered bottom-water reservoirs has been a question, and there were limited studies in the literature. Aiming at the study of a specific low amplitude, moderate-high permeability, thin lens-like sandstone reservoir with bottom-water in Hutubi river layer in Luliang oilfield of Xinjiang, by using a variety of methods in geology, drilling, reservoir engineering and numerical simulation, and combined with the effects of horizontal wells during the reservoir development, we demonstrated the relation respectively between various factors of horizontal well length and wellbore pressure loss, reservoir adaptability, and development of oil drilling rate effects of such reservoir. Then, we proposed the range of the reasonable length of horizontal wells considering both theoretically and practically. The results showed good reliability and applicability, providing technical reference for the research and application of horizontal wells in similar bottom-water reservoirs.

Key words: thin-layered, lens-like, moderate-high permeability, sandstone bottom-water reservoir, horizontal well length
