Manufacturing method and mold for integral molding of composite slips

Abstract

The invention relates to a method and a mould for manufacturing one-piece composite material slips, and is used for making the composite material slips; the composite material slips comprises a slips base body (1) and teeth (2); the method for manufacturing the composite material slips comprises the following steps of: S1, assembling, mould pressing and forming the mould, and adjusting the position of a hydraulic push rod; S2, arranging the teeth (2) on the top end of the hydraulic push rod; S3, closing the mould and filling composite material into a mould cavity; S4, heating the mould up to 150-300 DEG C and pressuring the mould up to 30-60KN; S5, starting a hydraulic cylinder, and pushing the teeth (2) into the mould cavity; and S6, demoulding after heat preservation is carried out for 30-60min. The mould comprises an upper mould (101), a lower mould (102) and the hydraulic push rod (104). According to the invention, the teeth are inserted and buried into the slips base body at the different angles, and the teeth and the slips base body are molded into a whole; and the method is few in processing steps, high in production efficiency and capable of realizing rapid large scale production.

Description

technical field [0001] The invention relates to the field of petroleum industry, and more specifically, relates to a manufacturing method and mold for integral molding of composite material slips. Background technique [0002] During the development of oil and gas wells, in the case of oil testing, acidizing, fracturing, oil production plugging, etc., the wellbore must be blocked or divided into multiple well sections for operation. In addition to packers and cement plugs, bridge plugs are the main means of wellbore stratification or segmental isolation, and slips are an important part of bridge plugs. Existing slips are made of metal, which are not easy to drill and grind, and most of them are made by machining, the production process is complicated, and raw materials are wasted. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manufacturing method and mold for integrally forming composite material slips with ...
