Problems solved by technology
[0003] At present, due to the high-molecular polymer rubber powder, which has high viscosity and is easily soluble in water, it is easy to produce powder when it contacts with water, and once the powder is formed, it is difficult to be opened, which affects the glue. Viscosity is also a great waste of rubber powder, and the jet injector used on site is only processed and manufactured based on experience, the work efficiency is low, and the injector is prone to clogging and uneven mixing of the mixed liquid during use

A solution-preparing jet device comprises a main body. The upper end of the main body is connected with a work nozzle which is connected with a suction chamber, the suction chamber is connected with a mixing chamber, a feed inlet is formed in the side face of the mixing chamber, and a regulating valve is arranged on the feed inlet; the feed inlet is limited on the main body through a limiting ring, the lower side of the mixing chamber is connected with a diffusion chamber, and the lower end of the diffusion chamber is connected with a jet nozzle which is embedded in the main body. During practical application, an oil string is connected with the main body of the solution-preparing jet device, the main body is downwards placed in a designated position in a well, water enters the work nozzle through a pipeline and enters the suction chamber, and the regulating valve is adjusted in advance to ensure the quantity of colloidal powder entering the feed inlet; the high-molecular polymer colloidal powder is added into the feed inlet, the water and the colloidal powder are fully stirred and mixed in the mixing chamber, and a mixture enters the diffusion chamber and is quickly jet into a pressed-open stratum fracture through the jet nozzle; and accordingly the solution preparing quality and work efficiency are improved, and the underground fracturing effect can be improved.
Description
technical field [0001] The invention relates to a liquid dispensing system in the petroleum and petrochemical field—a liquid dispensing jet. [0002] technical background [0003] At present, due to the high-molecular polymer rubber powder, which has high viscosity and is easily soluble in water, it is easy to produce powder when it contacts with water, and once the powder is formed, it is difficult to be opened, which affects the glue. Viscosity is also a great waste of rubber powder, and the jet injector used on site is only processed and manufactured based on experience, the work efficiency is low, and the injector is prone to clogging and uneven mixing of the mixed liquid during use. Contents of the invention [0004] In order to solve the problems in the background technology, the present invention provides a liquid dispensing system—a liquid dispensing injector, which can add rubber powder, so that the rubber powder is mixed with air first and then enters the water, a...
