Packer Suspension Liner Cementing Technology in Extended Reach Well in Chenbei Block of the Bohai Sea
-
Abstract
In view of the technical difficulties occurred during liner cementing in extended reach wells in Chenbei Block of of the Bohai Sea, a series of technical measures and requirements have been put forward, and advanced cementing technologies for inclined well have been developed. Taking Well CB32B-1 as an example, the taken measures have created favorable conditions for the successful placing of line, sitting and sealing of wall packers as well as liner cementing. The cementing quality is excellent through acoustic amplitude CBL evaluation. The practice of the cementing has showed that this series of measures are effective on improvement of the cementing quality, which can provide related references for packer suspension liner cementing in such kind of offshore complex well in later days.
