水平井技术是进行低渗透薄储层、储量小的边际油气藏等开发的关键技术,同时,压裂酸化工艺技术也是对不合格水平井进行改造的关键技术。水平井的压裂酸化工艺和直井压裂酸化工艺的工作重点不同,近年来,水平井压裂酸化技术在进行低渗透油气藏方面发挥的作用越来越明显,为提高油气质量做出了一定的贡献,本文对水平井酸化工艺技术进行了重点分析探讨,并对水平井的改造工艺进行了简单的介绍。 Horizontal well technology is the key technology for the development of low-permeability thin reservoirs and marginal reservoirs with small reserves. At the same time, fracturing and acidizing technology is also the key technology to transform unqualified horizontal wells. In horizontal well fracturing and acidizing process and vertical well fracturing and acidizing process work are different in focus, in recent years, the horizontal well fracturing and acidizing technology in the role of low permeability reservoirs play more and more obvious, in order to improve the quality of oil and gas has made a certain , This paper analyzes and discusses the horizontal well acidification process technology, and introduces the reform process of horizontal well briefly.
