WELLS DEVICE AND METHOD FOR COMBATING SAND INSURANCE DOWN WITH THE APPLICATION OF GRAVEL RESERVE

摘要

The method of completing a well bore in a subterranean formation includes creating a sand filter assembly represented by one or more sand filter links, a column link layout, and a packer layout. The packer layout has at least one packer which is mechanically installed in its working position with at least one alternative flow channel. The sand filter assembly and column stack arrangement also each has transport pipes for transferring gravel suspension and gravel filter filling pipes for feeding gravel suspension. The method also includes launching a sand filter assembly, a connected column link assembly and a packer assembly into a wellbore, and placing a sealing member of the packer assembly in contact with the surrounding wellbore. Thereafter, the method involves injecting a gravel suspension into the wellbore to form a gravel filter, in which a reserve of gravel filter filling material is located above the sand filter assembly. A well completion device has also been created, which provides for laying a gravel reserve.
