国外水平井油井产能预测研究现状

Overseas Research Situation of Flow Potential Predication in Horizontal Well

水平井在油气田开发中的应用越来越受到人们的重视。水平井的优越性如今已成为不争的事实，世界各地在短短几年中竞相钻成数千口水平井就是证明。水平井生产时的产量通常要比直井高2～5倍。本文从单向流、两种情况分析了预测模型的建立及在应用过程中的不足，并介绍了裸眼完井和射孔完井两种不同完井方式的产能预测模型，对进一步深入研究水平井产能的技术研究具有一定的指导意义，为更好的应用水平井技术高效高速开发特殊油气藏，提高油气井产能，提供了技术支持。

The horizontal well＇s is valued more and more in oil--gas field development application by people. The horizontal well＇s superiority has become the fact which now does not struggle, the world com- petes to drill several thousand horizontal wells is in several years proved. The horizontal well produces when the output usually must be higher than 2-~5 times the vertical shaft. This article from the uniflow, two kind of situation analysis forecast model＇s establishment and in the application process＇s insufficiency, and introduced the open hole completion and the perforation well completion two different well completion ways＂produce can the forecast model, produces to further deep research horizontal well can the engineering research have certain guiding sense, for the better application horizontal well technology highly effective high speed development special oil gas pool, enhances the oil gas well to produce energy, has provided the technical support.
