Embodiment Construction

[0021] See attached figure 1 , a multi-channel ejector-suction fracturing fluid mixing device, mainly composed of a connecting flange 1, a joint 2, a sealing ring 3, a nozzle 4, a vacuum pump body 5, a manifold system 6, a flow meter 7, and an automatic valve 8. The main body of the mixing device includes a jet-suction pump and a manifold system 6 connected to the jet-suction pump. The inlet and outlet ends of the jet-suction pump are respectively connected with flanges. The pump outlet line is connected to the mixed solution outlet line. The jet-suction pump includes a joint 2 and a vacuum pump body 5. The vacuum pump body 5 is provided with a number of liquid suction holes 9 communicating with the vacuum cavity 10 of the jet-suction pump. The liquid suction holes 9 are arranged reasonably according to the actual situation; the manifold system 6 includes A plurality of suction lines for conveying liquid additives are respectively installed on the liquid suction holes 9 of th...

Abstract

The invention provides a multichannel injection type fracturing liquid mixing and blending device. The multichannel injection type fracturing liquid mixing and blending device comprises an injection pump and a manifold system connected with the injection pump, wherein the water inlet end of the injection pump is connected with a main pump outlet pipeline; the water outlet end of the injection pump is connected with a mixed liquid outlet pipeline; the injection pump comprises a joint and a vacuum pump body; a plurality of liquid suction holes communicated with the vacuum pump body of the injection pump are formed in the vacuum pump body; the manifold system comprises a plurality of suction pipelines delivering liquid additives; each of the suction pipelines is mounted at each of the liquid suction holes of the vacuum pump body. The different liquid additives are added to the mixed liquid, so that the problems that the additives are mixed unevenly and the original equipment is complicated in structure can be solved; the addition of each additive component of the fracturing liquid can be controlled precisely according to the formula; the multichannel injection type fracturing liquid mixing and blending device is simple in structure, low in cost, and easy to process and manufacture.

Description

technical field [0001] The invention belongs to fracturing fluid mixing equipment, and relates to a parallel injection-suction type dispensing device, in particular to a multi-channel jet-suction type fracturing fluid mixing device. Background technique [0002] Fracturing fluid preparation is a key process in oilfield hydraulic fracturing operations, and it is necessary to ensure that the fracturing fluid is prepared uniformly and effectively under any conditions. At present, metering pumps are mainly used in oilfields to realize the metering and dosing of various components of fracturing fluid, and then uniformly mixed by the stirring system. Metering pumps need to be equipped with a set of power sources (including motors, reducers, etc.) to provide power for dosing. In addition, the mixing system also needs to be equipped with motors, reducers and other devices, which have high cost, many components and complex structure. More importantly, this set of configuration syst...
