Typical application of ultra-short radius multi-branch well technology in Z oilfield,South China Sea
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 the first to use China National Offshore Oil Corporation's self-developed tools and has achieved success for the first 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 oil fields.
