摘　　要：受平台槽口少、原油采出程度低等因素的影响,渤海油田引入多级分支井钻完井技术,在保留原井眼生产层位的同时,侧钻分支井眼进行开采,结合该类井1个槽口对应2个生产井眼的特殊井筒构造,深入分析主井眼及分支井眼轮换开采的可操作性,研究形成了包括管柱组合、工序操作等配套的分支井轮采工艺,为渤海油田同类井身结构多井眼的轮换开采提供了参考和借鉴。By platform less notches,low oil recovery degree of factors,the influence of the bohai sea oil field is introduced into multiple branch well drilling and completion technology,while retain the original hole production horizon,sidetracking branch hole mining,combing with the class a slot hole corresponding to the two production special wellbore structure,analyzes the main branch hole and hole mining the operability of rotation,The research has formed the branch well rotation production technology including string combination,process operation and so on,which provides a reference for the similar well structure multi-hole rotation production in Bohai oilfield.
