近年来,我国的水平井完井技术进步迅速,各种岩性的油气藏都有水平井钻成,且已由过去单一的固井射孔完井技术发展成为拥有适合多种油藏类型、保护油气层、提高水平井产能及采收率的综合工艺技术。但是,完井技术还存在难点,本文详细介绍了控制底水脊进的技术现状。另外,本文探讨水平井完井技术发展趋势,以期依靠技术提供油层采收率。
In recent years, horizontal well completions in China have progressed rapidly. All types of lithologic reservoirs have horizontal wells drilled and have evolved from single well completion perforation and completion technologies to multi-reservoir wells with various reservoir types, Protection of oil and gas layers, improve horizontal well productivity and recovery rate of integrated technology. However, there are still some difficulties in the completion technology. This article details the current status of technology for controlling the bottom water ridge. In addition, this paper discusses the development trend of horizontal well completion technology, with a view to providing oil recovery by technology.
