Problems solved by technology

[0002] At present, fracturing and acidizing is mainly limited to carbonate reservoirs—limestone and dolomite, and has two purposes: removing formation damage and improving undamaged reservoirs; different additives need to be added when configuring fracturing fluids, if If the additives cannot be mixed well, the acidification effect of the fracturing fluid will be reduced, so there is a lack of a mechanism for mixing the additives

Abstract

The invention provides a stirring and conveying device for petroleum fracture acidizing, which comprises a uniform mixing cylinder, a uniform mixing driving mechanism and a base, during working, various additives needing to be uniformly mixed are injected into the uniform mixing cylinder through a material inlet, then the uniform mixing driving mechanism is started, the stirring mechanism is further enabled to work, so that the purpose of uniformly mixing the additive in the uniform mixing cylinder is achieved, after uniform mixing is finished, the discharge port of the uniform mixing cylinder is opened, and the uniformly mixed additive is output and used for petroleum fracture acidizing; according to the stirring and conveying mechanism provided by the invention, the working efficiency of uniformly mixing additives is greatly improved, and the condition of fracture acidizing failure in the petroleum fracture acidizing process caused by incomplete uniform mixing is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of petroleum fracturing acidification, in particular to a stirring and conveying device for petroleum fracturing acidification. Background technique [0002] At present, fracturing and acidizing is mainly limited to carbonate reservoirs—limestone and dolomite, and has two purposes: removing formation damage and improving undamaged reservoirs; different additives need to be added when configuring fracturing fluids, if If the additives cannot be well mixed, the acidification effect of the fracturing fluid will be reduced, so there is a lack of a mechanism for mixing the additives. Contents of the invention [0003] The invention provides a stirring and conveying device for petroleum fracturing and acidizing, which is used to realize the mixing of additives and improve the mixing efficiency and the acidifying effect of fracturing fluid. [0004] The invention provides a mixing and conveying device for oil fr...
