Description

Technical Field

[0001] The utility model relates to the technical field of liquid preparation and injection, in particular to a liquid preparation and injection device for gas field fracturing. Background Art

[0002] During fracturing, special fracturing fluids such as fibers and straws and a unique pumping procedure are used to consolidate ordinary proppant particles into agglomerates, thereby forming high-conductivity channels in the proppant filling layer. The conductivity is several orders of magnitude higher than that of conventional fractures, and it can also effectively prevent the proppant from flowing back in the reservoir fracture network, which can effectively increase the gas well production.

[0003] In the process of using the existing liquid preparation and filling device for gas field fracturing, the liquid preparation tank is generally placed directly on the cart, and then the liquid preparation and filling is carried out through the filling gun on the liquid preparation tank. The stability of the liquid preparation tank is poor during the movement, and the liquid preparation gun has no relevant limiting mechanism. The liquid preparation gun is easily damaged if it is placed randomly. Therefore, we have introduced a new liquid preparation and filling device for gas field fracturing. Utility Model Content
