摘　　要：在开展超短半径多分支井技术实施的可行性论证的基础上,通过精细方案设计及实施超短半径多分支井技术。该技术首次使用中国海油自研工具,在Z油田S井首次取得成功,创新解决合采层间压制问题,单井增产倍比达2.7倍且较稳定,为海上类似油田的开发积累了宝贵的增产技术经验。On the basis of feasibility study on the implementation of ultra short radius multi branch well technology,fine scheme design and implementation of ultra short radius multi branch well technology are carried out.This technology is thefirst to use China National Offshore Oil Corporation's self-developed tools and has achieved success for thefirst time in the S well of Z oilfield.It innovatively solves the problem of interlayer compression in co production,with a single well yield increase ratio of 2.7 times and relatively stable.It has accumulated valuable experience in production increase technology for the development of similar offshore oilfields.
