国内外分支井五级完井技术发展趋势
|
摘要
分支井技术具有显著降低钻井成本、适应稠油及边际油田等特殊油藏开采模式、提高新老油田采收率等优点。分支井五级完井技术采用机械支撑方式,建立主、分支井眼连接通道;实现了液力密封;对于分支井眼,后续还可选择性重入。介绍了多分支井的分类体系。调研了国内外多级完井技术发展现状,介绍了斯伦贝谢RapidX系统、哈里伯顿FlexRite系统、贝克休斯Hook系统等国外石油服务公司的海上油田五级分支井技术,比较了各公司的五级多分支井的关键技术优缺点。对国内五级完井技术发展进行了展望。
Multilateral well completion technology significantly reduces drilling costs,enables the special oil reservoir exploitation mode for heavy oil and marginal oil fields and improves oil recovery of old and new oilfields.TAML5 technology,which can realize the complete mechanical support and hydraulic sealing performance at the joint of branch hole and main hole with selective reentry function after completion,applies more and more widely in oil and gas field development.The classification system of multilateral well completion technology was introduced,the development status of multilateral well completion technology at home and abroad was discussed.The TAML5 technology of Schlumberger's RapidX system,Halliburton's FlexRite system,Baker Hughes' Hook system and other foreign oil service companies were introduced in details and the comparing of the advantages and disadvantages of the key technologies of TAML5 was focused.
