The separated layer polymer injectionpipe string consists of well-flushing packer, down-hole flow distributor and bottom ball.
分层注聚管柱主要由可洗井封隔器、配注器及底球组成。
2
More injection flow rate, slim branch injectionpipe and long pipeline resulted in more resistance at the branch injectionpipe.
由于注水量较高、注水支线管径较细、管线较长等原因,导致注水支线阻力偏大;
3
The anchoring or set to the artificial bottom hole of the separate injectionpipe string has solved the creep of the pipe string resulted from the unstable water injection pressure.
