The invention provides an acidified fracturing fluid ready-to-use device, which includes a mixing tank, an additive unit, a thickener unit, and an acid liquid unit are connected in parallel at the inlet end of the mixing tank, and a first centrifugal pump, a first The buffer tank, the second centrifugal pump, the third pneumatic gate, the second buffer tank, the fifth pneumatic gate and the discharge pump; the first pneumatic gate is connected in series between the outlet port of the acid unit and the inlet port of the mixing tank; A second pneumatic gate is connected in parallel between the outlet port and the inlet port of the discharge pump; a fourth pneumatic gate is connected in parallel between the outlet port of the first buffer tank and the inlet port of the discharge pump; four function valves are respectively set in the two buffer tanks. zone, the functional zone is provided with a first agitator and a serpentine baffle. The device realizes the ready-to-use acid solution, and the prepared acid solution has no stratification and agglomeration phenomenon, which improves the quality of the acid solution. At the same time, the device can save the link of acid unloading and liquid preparation in the acidification process, improve the effect of acidification transformation and operation efficiency, and reduce production costs.
Description
technical field [0001] The invention relates to the technical field of fracturing equipment for oil and gas wells, in particular to a ready-to-use device for acidizing fracturing fluid, which is one of the important equipments for fracturing and acidizing construction. The device can not only complete the preparation of acid solution on the acidizing site, but also cooperate with the fracturing pump truck to carry out acidizing reconstruction construction. Background technique [0002] In recent years, acidizing fracturing has become an important means for effective stimulation and stimulation of lower paleo-reservoir in the Ordos Basin, and the quality of acidizing fracturing fluid directly determines the improvement of formation permeability, that is, affects the effect of improving formation stimulation. The equipment used for fracturing fluid preparation is the focus of acidizing renovation. [0003] At present, in the preparation process of acidizing fracturing fluid, ...
