分支水平井技术研究与应用

Studies and Application of Branch Horizontal Wells Technology

分支水平井技术是一个集油藏工程、钻完井工程、油田化学工程等为一体的集成系统．可实现油气藏的高效立体式开发，增加井筒与油藏的接触面积，降低原油开采成本，显著提高油气产量和最终采收率。长城钻探工程院分支水平井技术经过多年的研究与现场实践已逐步成熟和完善，在各种油气藏应用取得了良好的开发效果．单井产量大幅度提高，钻完井成本显著降低。，分支水平井技术具有广阔的发展前詈，并逐步开始规模化应用。

The branch horizontal wells technology is a integrated system which includes reservoir engineering, drilling and completion engineering, oilfield chemical engineering etc. By the technology, the reservoirs can be developed effectively in three-dimensional mode. The contact area of wellbore in reservoirs is increased. The crude oil exploiting cost is reduced and the oil and gas output and ultimate recovery rate are raised notably. After many years of research and practice, the branch horizontal wells technology of GWDC has been gradually matured and improved. The good exploitation effect and high recovery rate has been appearing when it is applied on various kinks oil and gas reservoirs, while a great deal of investment saved for oil company. The branch horizontal wells technology has broad prospects for development and gradually began large-scale applications.
