Abstract

The invention discloses a signal-controlled underground thermoplastic reinforced composite pipe and a manufacturing process thereof. The signal-controlled underground thermoplastic reinforced composite pipe consists of a thermoplastic reinforced composite pipe, a power supply wire, a signal control wire and a protecting layer; the power supply wire and the signal control wire are arranged on the outer surface of the thermoplastic reinforced composite pipe; the protecting layer wraps the surfaces of the thermoplastic reinforced composite pipe, the power supply wire and the signal control wire; firstly, the power supply wire and the signal control wire are wound on the outer surface of the thermoplastic reinforced composite or axially prefabricated; and then, the protecting layer is molded out of the thermoplastic reinforced composite pipe, the power supply wire and the signal control wire through extruding. The signal-controlled underground thermoplastic reinforced composite pipe realizes monitoring and transmission of underground pressure and temperature signals, can control underground water injection and oil production devices, and has the advantages of simple structure, convenience for use, safety and reliability.

Description

technical field [0001] The invention relates to the technical field of pipe processing for oil and gas fields, in particular to a signal-controllable thermoplastic reinforced composite pipe for downhole and a manufacturing process thereof. Background technique [0002] With the continuous development of the oil and gas industry, the matching thermoplastic reinforced composite pipe industry is also developing rapidly. At present, the use of thermoplastic reinforced composite pipes in downholes is also expanding, mainly for water injection and oil and gas transportation. When collecting downhole temperature and pressure data, the thermoplastic reinforced composite pipe is required to stop working, and the logging device is used to go downhole through the thermoplastic reinforced composite pipe to collect temperature and pressure data, which increases the workload and working time; at the same time, the thermoplastic reinforced composite pipe The reinforced composite pipe and ...
