摘要
径向水平井钻井技术在我国现已处在开发应用阶段,通过对近几年来国内各大油田应用径向水平井技术的情况调研和相关资料研究表明,此技术非常适合于开发低渗透油层和薄油层,对提高油田采收率非常有效。但是在应用中存在扩孔困难、油层容易污染等问题,而且施工成本高。为此提出了用无需扩孔的小直径生产管来代替传统的32 mm生产管的新思路,这种技术具有创新性。文中应用有关流体力学知识对其可行性进行了分析,提出了实现此项新技术的几点看法。
Radial horizontal well drilling in China has developed and applied. The survey of the application of radial horizontal well in China shows that this technology is suitable for low and shallow filtration formation, thus it benefits to production. In practical application, it also shows its shortcomings such as. hole expand, pollution to oil formation, and high cost. The paper presents a new thought of nonradial expand tube replacing conventional production tube （32mm）. The hydromechanics is used for analysis and some points are put forward in the paper as well.
