Example Embodiment

[0041] The technical solutions of the present invention will be described in conjunction with specific embodiments. Obviously, the described embodiments are merely embodiments of the invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained in the art without creative labor are not made in the pre-creative labor.

[0042] EXAMPVIT figure 1 As shown, including the mixed acid tank 1 and the buffer tank 2, the mixed acid tank 1 includes a tank 11, and the tank body 11 is fixedly connected to a cylindrical partition plate 12, and the separator is fixedly connected to the liquid on both sides of the separator. Bit sensor 13. The partition plate 12 separates the can body 11 into a stirring chamber 111 and the stirring chamber, and the can body 11 is rotatably coupled to the stirring rod 121 and the stirrer 2 122, which extends into the stirring chamber 111 and the stirring cavity, respectively. The tank 11 is connected to th...

Abstract

The invention relates to the field of oil and gas field acid fracturing construction devices, and discloses an acid mixing tank and a buffer tank; the acid mixing tank comprises a tank body, a cylindrical partition plate is fixedly connected in the tank body, and the tank body is divided into a first stirring cavity and a second stirring cavity by the partition plate; and a first stirring rod and a second stirring rod which respectively extend into the first stirring cavity and the second stirring cavity are rotationally connected in the tank body. The device has the following advantages and effects that the first stirring cavity and the second stirring cavity are formed in the tank body, and acid fracturing fluid is mixed, stirred and conveyed in turn through the two stirring cavities, so that the mixing continuity of the acid fracturing fluid is improved, the use amount of an acid storage tank is reduced, and the load of a mixing vehicle is reduced; and by using the mixed pickling system, the automatic control of mixing and stirring of the acid fracturing fluid is realized.

Description

technical field [0001] The invention relates to the field of acidizing and fracturing construction devices for oil and gas fields, in particular to a mixed acid washing system for fracturing vehicles. Background technique [0002] Acid fracturing is the most effective stimulation measure for carbonatite and complex lithology fractured reservoirs. The quality of acidizing fracturing fluid directly determines the quality of improving formation permeability. The main components of acidizing fracturing fluid include hydrochloric acid, hydrofluoric acid, thickener (polyacrylamide), corrosion inhibitor, drainage aid, surfactant, etc. , in the acidizing operation, it is necessary to mix all the materials evenly in advance, and the key technology restricting the acidizing operation is the continuous mixing of acid liquid. At present, the mixing of acidizing fracturing fluids adopts the traditional method, which is mainly to manually calculate and weigh, and then inject the concentr...
