The upper part of the cementing sleeve is equipped with a sealing mechanism to ensure the wellbore integrity of the fractured tubular column during fracture pumping.

Tubular column structure.

Casing + return joint seal cylinder + cementing hydraulic sleeve + naked eye packer + ball drop fracture sleeve + naked eye packer + differential pressure sleeve + pressure bearing short joint + floating shoe.

Insertion of seal barrel + back joint seal insert.

The 3.5" tail pipe segmented fracturing column slip set can be divided into 15 segments with ball drop sizes of 1.125"-2.625".

The 4.5" tailpipe fracturing column slip set is available in 20 sections with a ball size of 1.125"-3.75".
