Fracturing fluid jet mixer

Abstract

The invention relates to a fracturing fluid jet mixer. In order to overcome the defect that the jet mixer in the conventional fracturing equipment cannot be regulated in real time to supply fracturing fluid needed by fracturing operation in time, a suction tube, a reducing tube, a choke and a diffuser of the fracturing fluid jet mixer are sequentially connected and mounted; the middle part of the reducing tube is a conical tube which is reduced from the front to the rear, and the diffuser is a conical tube which is reduced from the rear to the front; an inserted tube is an elbow, the front end of the inserted tube is mounted on the body of the suction tube, the rear end part of the inserted tube is a blind hole tube which is positioned in the conical hole of the reducing tube, and a gap is reserved between the rear end of the inserted tube and the conical hole of the reducing tube; the wall of the inserted tube is provided with a radial through hole; the front end of the reducing tube is screwed in the rear end of the suction tube, and the rear end of the reducing tube is slidably connected with the chock; and an additive suction tube is fixedly arranged on the wall of the chock or the suction tube, and is communicated with the inner hole. The fracturing fluid jet mixer has the advantages that: the structure is simple, and the chock of the fracturing fluid jet mixer is driven to rotate by a motor, so that the position between the rear end of the inserted tube and the conical hole of the reducing tube can be changed to carry out mixing adjustment.

Description

Technical field [0001] The invention relates to a fracturing fluid mixer in fracturing construction equipment for oil and gas development, in particular to a jet mixer. Background technique [0002] In the process of oil and gas development, in order to improve the recovery factor, it is necessary to stimulate the production of reservoirs, and fracturing construction is one of the main technical means. During the fracturing construction process, it is necessary to mix the specified proportion of sand, water, bonding agent, chemical dry powder, etc. through liquid mixing and liquid mixing equipment, and then pressurize it into the bottom of the well through a pump truck. At present, the fracturing fluid mixing systems used in the field all use a jet mixer or a jet type dry powder adding device to complete the fracturing fluid mixing. The Chinese utility model patent "Jet type dry powder adding device" published on July 14, 2004 (publication number CN2625578Y), the Chinese ut...
