Novel small and micro displacement fracturing vehicle

Abstract

The invention provides a novel small and micro displacement fracturing vehicle, which comprises a chassis vehicle and a sub beam, wherein the sub beam is connected with the chassis vehicle through a pull plate; an engine and a gearbox are arranged on the sub beam through screw bolts; the gearbox is arranged at the output end of the engine; the top, positioned at one side of the gearbox, of the subbeam is provided with a hydraulic system through a screw bolt; a first pump base is welded at the top, positioned at one side of the hydraulic system, of the sub beam; a fracturing pump is arranged on the first pump base; the gearbox and the fracturing pump are connected through a transmission shaft; a metering tank is welded at the top, positioned at one side of the fracturing p ump, of the subbeam; a second pump base is welded at the top, positioned at one side of the metering tank, of the sub beam; a small-size high-pressure injection pump is arranged on the second pump base through a screw bolt. The novel small and micro displacement fracturing vehicle has the advantages that the design is reasonable; the equipment is highly integrated; the functions are various; the equipment buyingand maintenance cost can be effectively reduced.

Description

technical field [0001] The invention is a novel fracturing vehicle with both small and micro displacement, and belongs to the technical field of fracturing and thick oil thinning operation equipment. Background technique [0002] Acid fracturing operation means that the mixed acid solution is injected into the bottom of the well after being pressurized by the plunger pump on the fracturing vehicle, the formation is crushed to form artificial fractures, and the fracture is corroded by the acid solution to improve the permeability of the formation. The plunger pump is suitable for large displacement and short-term operation conditions. Heavy oil thinning operation refers to the continuous long-term high-pressure injection of thin oil, diluent, water and other mixed liquid into the bottom oil layer through the plunger pump. The plunger pump used is suitable for Small displacement, high pressure and long-term working conditions. At present, the acid fracturing and heavy oil dil...

AI Technical Summary

Problems solved by technology

At present, the acid fracturing and heavy oil dilution equipment used in the oil field are restricted by the displacement, pressure and continuous operation time of the configured plunger pump. Only two sets of equipment can complete the corresponding operations. On the one hand, it will directly increase the use and maintenance costs of user equipment, resulting in waste of human and material resources; on the other hand, with the development of oilfield technology, the construction site urgently needs automated and integrated equipment. The development trend of oilfield equipment, for this reason, the present invention provides a new type of small and micro displacement and fracturing vehicle
