苏里格气田为低孔、低渗、低产的三低特征,采用水平井开发模式在合理提高气层利用率,提高天然气产量等方面在该地区收到了良好的效果。水平井入窗技术是水平井地质导向工作当中的重点。在工作基础、科学论断、方式方法、技术措施、实践认知等方面对入窗技术的研究,为水平井开发施工做出了重要的技术保障。 The Sulige gas field is a low-porosity, low-permeability and low-yielding three low features. The horizontal well development model has received good results in the region in terms of reasonable utilization of gas reservoirs and natural gas production. Horizontal well-entry technology is the focus of horizontal well geosteering. The study of window technology in terms of working foundation, scientific judgment, ways and means, technical measures and practical cognition has made important technical support for the development and construction of horizontal wells.
