Abstract

The invention discloses an acid fracturing thermal washing sledge. A fuel heater, a fuel tank, a diesel engine, a gearbox, a water cabinet, an air compressor system, a shaft coupling, a three-cylinder plunger pump, a lubricating system, a high-pressure system, a circuit system, a low-pressure manifold system, a heater, a centrifugal pump and a hydraulic system are arranged on a sledge frame; the fuel heater is fixed beside the diesel engine; the gearbox is connected with the diesel engine through a screw; the gearbox is connected with the three-cylinder plunger pump through the shaft coupling; the water cabinet is fixed above the shaft coupling; the air compressor system is fixed below the water cabinet; the centrifugal pump is fixed between the water cabinet and the heater. The acid fracturing thermal washing sledge is applied to acid fracturing, scavenging, well cleaning and wax removing under variable working conditions, can adapt to low-temperature severe climate conditions, and has a plurality of functions.

Description

technical field [0001] The invention relates to a novel oil field acidizing and fracturing thermal washing skid. Background technique [0002] The existing acid fracturing, thermal washing and wax removal, and purging functions are all separate single-piece operations, so that there are many equipment stored in the well site, and the equipment cost is high, which is not conducive to the operation and use of the staff. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new oilfield acidizing fracturing thermal washing skid, which integrates the functions of three skids, realizes one machine with multiple functions, is easy to operate, and has a reliable profile. It is the future development of integration trend. [0004] In order to solve the above-mentioned technical problems, the present invention is realized as follows: a kind of acidification fracturing heat washing skid, is provided with fuel heater, fuel tan...
