Anticorrosion, scale-inhibition and paraffin-inhibition device and system

Abstract

The invention provides an anticorrosion, scale-inhibition and paraffin-inhibition device and system. The anticorrosion, scale-inhibition and paraffin-inhibition device sequentially comprises a corrosion-inhibition anticorrosion part, a corrosion-inhibition scale-inhibition part and a scale-inhibition paraffin-inhibition part from top to bottom, and the corrosion-inhibition anticorrosion part, thecorrosion-inhibition scale-inhibition part and the scale-inhibition paraffin-inhibition part can be detachably connected. The corrosion-inhibition anticorrosion part comprises an adapting pipe, and ananode pipe is embedded into the adapting pipe. The corrosion-inhibition scale-inhibition part comprises a supporting pipe, a turbulent flow pipe is axially arranged in the center of the supporting pipe, a through hole is formed in the pipe wall of the turbulent flow pipe, and a corrosion-inhibition scale-inhibition rod is embedded into an annular space between the supporting pipe and the turbulent flow pipe. The scale-inhibition paraffin-inhibition part comprises a screen pipe, and a scale-inhibition paraffin-inhibition block is embedded into the screen pipe. The anticorrosion, scale-inhibition and paraffin-inhibition device and system provided by the invention is an organic combination of the anticorrosion, scale-inhibition and paraffin-inhibition functions, the anticorrosion, scale-inhibition and paraffin-inhibition functions are effectively integrated, the pipe string structure is simplified, mounting and replacing are convenient, the anode pipe, the corrosion-inhibition scale-inhibition rod and the scale-inhibition paraffin-inhibition block can be replaced and replenished along with a well according to use consumption, the cost is reduced, and the labor intensity of workers from the first production line is relieved.

Description

technical field [0001] The invention relates to the field of oil exploitation equipment, and more specifically, to an anti-corrosion, scale, wax and anti-wax device and system. Background technique [0002] Usually, in the process of oil extraction, the oil well production string will be corroded due to the long-term transportation of a large amount of crude oil, and will also be scaled and waxed, which not only seriously hinders the extraction and transportation of crude oil, shortens the service period of the string, but also Increase the number of pump inspections and maintenance costs of the oil well, and increase the labor intensity of the staff. At present, there are many ways to solve the corrosion, scaling and waxing of tubing, such as adding various devices and short connections to the production tubing string to realize the functions of anti-corrosion, anti-scaling and anti-wax respectively, but these devices have single performance and scattered structures , resu...

Problems solved by technology

At present, there are many ways to solve the corrosion, fouling and waxing of tubing, such as adding various devices and short connections to the production tubing string to realize the functions of anti-corrosion, anti-scaling and anti-wax respectively, but these devices have single performance and scattered structures , resulting in difficulty in connecting the tubing strings and difficult operation, resulting in a complex structure of the production tubing string and great potential safety hazards
