Abstract

The invention discloses an accurate fluid distribution device and a fracturing fluid distribution system and relates to the technical field of fracturing fluid distribution. The accurate fluid distribution device comprises a feeding mechanism, a stock bin and a quantitative conveying mechanism, wherein the feeding mechanism is connected with the stock bin; the quantitative conveying mechanism comprises a driving component, a feeding screw rod and an accommodating drum; the driving component is connected with the feeding screw rod so as to drive the feeding screw rod to rotate; the feeding screw rod is arranged in the accommodating drum; a feeding port and a discharging port are formed on the surface of the accommodating drum; the stock bin is connected with the feeding port; and the discharging port is used for connecting a stirring tank of a fracturing blender truck. Compared with the fluid distribution device in the prior art, the accurate fluid distribution device provided by the invention has the advantages that the feeding mechanism connected with the stock bin and the feeding screw rod arranged in the accommodating drum are adopted so that the instant fluid preparation and use on the construction site can be realized, the cost and the space can be saved, and meanwhile, the proportion of the added materials is accurate, the fluid distribution efficiency is high and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of fracturing fluid preparation, in particular to a precise liquid dosing device and a fracturing fluid dosing system. Background technique [0002] Fracturing fluid refers to a heterogeneous and unstable chemical system formed by various additives in a certain ratio. It is a working fluid used in fracturing oil and gas reservoirs. Its main function is to transmit the high pressure formed by ground equipment. into the formation, fractures the formation to form fractures and transports proppant along the fractures. The process of oil layer hydraulic fracturing is to use high-pressure and large-displacement pumps on the ground, and use the principle of liquid pressure transmission to send a liquid with a certain viscosity (usually called fracturing fluid) to the oil layer with a pressure greater than the absorption capacity of the oil layer. Injection, and gradually increase the pressure in the wellbore, so a...
