Paraffin removal vehicle

Abstract

The invention discloses a paraffin removal vehicle, and relates to the technical field of oil field production increasing operation wells. The paraffin removal vehicle comprises a vehicle chassis, a heating device, a first pressurizing device and a manifold system, the heating device and the first pressurizing device are respectively arranged on the chassis; the manifold system comprises a liquid inlet pipe, a liquid outlet pipe and a first connecting pipe, the heating device and the first pressurizing device are connected through the first connecting pipe, the liquid inlet pipe is connected with the heating device, and the liquid outlet pipe is connected with the first pressurizing device. The problem that the high-pressure fluid medium is limited by boiler pressure and cannot meet the high-pressure requirement at least can be relieved.

Description

technical field [0001] The application belongs to the technical field of oil field stimulation operation wells, and in particular relates to a wax removal vehicle. Background technique [0002] When some current hot oil wax removal vehicles are in use, the liquid is generally pressurized to high pressure through a plunger pump, and then transported to the boiler for heating, and finally the high temperature and high pressure liquid is used for well washing and wax removal operations. [0003] However, some current hot oil wax removal vehicles have the following problems: [0004] 1) Limited by the boiler, the maximum working pressure is generally 20Mpa, which is difficult to meet the requirements of some deep wells and high pressure operating conditions; [0005] 2) The operating conditions are single, and only high-pressure hot water can be generated and injected into the well for wax removal and plug removal operations; [0006] 3) The built-in water tank is generally ai...

AI Technical Summary

Problems solved by technology

[0004] 1) Limited by the boiler, the maximum working pressure is generally 20Mpa, which is difficult to meet the requirements of some deep wells and high pressure operating conditions;

[0005] 2) The operating conditions are single, and only high-pressure hot water can be generated and injected into the well for wax removal and plug removal operations;

[0006] 3) The built-in water tank is generally airtight and can only be used to hold a single liquid such as water or crude oil;

[0007] 4) Low-pressure industrial working conditions cannot be realized, and in some deep well operations, the plunger pump's liquid absorption capacity is insufficient, resulting in long-term air suction, which will affect the service life of the plunger pump in the long run;

[0008] 5) After the well cleaning operation is completed, there is residual liquid in the coiled tubing, which has a corrosive effect on the inner wall of the coiled tubing and affects the service life of the coiled tubing;

[0009] 6) When the equipment is operated in some harsh environments, it will cause inconvenient operation and affect the physical and mental health of the operators, etc.
