中文摘要:E海低孔渗气田储量占总储量的93%,提高低渗透、特低渗透气田开采率,已经成为油气田勘探开发的重要课题。水平分支井技术成为提高低渗透、特低渗透气田开采率的重要手段,使用水平分支井技术提高气田开采率在国内外油气田开发已有先例且效果显著。水平分支井技术,是水平井和侧钻井等多种钻井技术的融合,是当今石油开采工业的热门技术,已在海油E海域多个油气田应用,是实现低渗气田高效开发的重要技术手段,因此,深入研究总结水平井分支井钻井技术意义重大。本文针对水平分支井侧钻技术深入分析并结合某气田水平分支井现场实钻情况,总结出水平分支井的在该区块现场应用的关键,为以后水平分支井在低渗油气田的推广和应用提供了借鉴的经验。

Application of Horizontal Branch Wells in gas field of Sea
Abstract:As reservoir with low porosity and permeability occupies 93% of all reserves of the E Sea, enhancing the recovery of low and ultra-low per permeability gas field has become an importance subject in the exploration and development of oil and gas field. Horizontal branch wells technology, which has been deployed and proved to be fruitful in enhancing gas field recovery at home and abroad, plays an significant role in increasing the recovery of low and ultra-low per permeability gas field. As for horizontal branch wells technology, it is a mix of horizontal well and side-tracking and multi-drilling technology and also a heated technology in oil development industry and has been implemented in several fields of the E Sea, and it also makes the effective development of low permeability gas field a reality. As a result , it is of much importance to deeply researching and summarizing this technology. This paper has deeply analyzed the technology and extracted the key points in E Sea fields based on the application in XX field, which can assists in further promotion and application of this technology in low permeability oil and gas fields in E Sea.
