Title:
PARAFFIN-DEPOSITION-PREVENTING INTELLIGENT PIPELINE SYSTEM FOR OIL FIELD
Document Type and Number:
WIPO Patent Application WO/2023/035461
Kind Code:
A1
Abstract:
A paraffin-deposition-preventing intelligent pipeline system for an oil field, the system comprising a pipe fitting (1), wherein the pipe fitting (1) comprises a connecting pipe (101), and core pipes (102) arranged on two sides of the connecting pipe (101); a pressure sensor (5) and a temperature sensor (6) are provided on the connecting pipe (101); outer sides of the two core pipes (102) are each provided with an outer sleeve (2) in a sleeved manner; the pipe fitting (1) and the outer sleeves (2) are assembled to form a mounting assembly; two sides of the mounting assembly are each provided with a pipe; and the two pipes are in communication with each other by means of the mounting assembly to form a communication pipeline. The state in the communication pipeline can be monitored in real time by means of the provided sensors, so as to control a metal wire and heating layers of the pipes to perform heating, so that the temperature in the pipeline rises to melt paraffin attached to the pipeline. The stability of heat transfer between the pipes is ensured by means of provided copper inserts. Convenient and quick mounting is achieved by means of fastening and pressing the core pipes, the outer sleeves and the pipes. The service life and usage efficiency of the pipes can be effectively prolonged and improved by means of a multilayer design of the pipes.
