水平井技术是一种高效的提高油气采收率的方法,在低渗透油藏、裂缝性油藏、薄油层油藏、断块油藏、稠油油藏、气顶底水油藏以及砾岩油藏中进行水平井开采,可以较大程度地改善开发效果。这项技术在世界各油田得到了广泛应用,已是提高油田开发水平的一项重要措施。我国的水平井技术起步较晚,在实际应用中,同国外相比还有较大差距。通过阐述新疆油区4 种不同油藏水平井开采现状,分析总结出水平井开采技术存在的问题,提出了改进意见和建议,为我国进行水平井开发提供了借鉴。

Production technology with horizontal well is an effective method to improve recovery ratio of reservoirs. Development efficiency can be improved by using the technology in low penetrability reservoirs , fractured reservoirs , thin layer reservoirs ,fault-block reservoirs , thickoil reservoirs , reservoirs with gas cap and bottom water and gravel reservoirs. This technology is used widely all around the world , and it has become an important measures to improve development level of reservoirs. This technology do not come to use until recent years in our country. There is much bigger difference in the actual using of the technology between China and the other countries. The papers explains the using status quo of the technology in Xinjiang Oilfield , and summarizes some problems existed in the using and the solutions methods.
