Long-transportation electromagnetic induction electric heat tracing and oil gas connecting system

Abstract

The invention belongs to the field of oil fields and particularly relates to a long-transportation electromagnetic induction electric heat tracing and oil gas connecting system. According to the system, holes are formed in an original oil conveying pipeline in a segmented mode, the hole of each section of the oil conveying pipeline comprises a head end hole and a tail end hole, an electric heat tracing belt is input from the head end holes and output from the tail end holes, head and tail connectors are respectively connected with a pressure adjusting controller through a sealing device, and the pressure adjusting controller is connected with a power source; the holes are sealed fully; a temperature sensor is arranged on the oil conveying pipeline and used for sending collected temperature values of the oil conveying pipeline to the pressure adjusting controller; the pressure adjusting controller is used for inputting voltage under an instruction of a service controller to the electric heat tracing belt, collecting voltage, current and power values of the electric heat tracing belt, and transmitting the obtained temperature values and the voltage, current and power values to the service controller through a network; the service controller feeds a pressure adjusting instruction back to the pressure adjusting controller. The system is convenient to operate and long in service life.

Description

technical field [0001] The invention belongs to the field of oil fields, in particular to a long-distance electromagnetic induction electric heat tracing oil and gas collection system. Background technique [0002] In the field of oilfields, generally, the peripheral blocks of oilfields have low production, low permeability, low abundance, poor crude oil physical properties, high freezing point, high wax content, high viscosity, low gas-oil ratio, scattered blocks, poor ground construction environment, far away The old area and the system rely on poor conditions. Therefore, in cold climates, it is impossible to use the traditional method of water supply and heat tracing for station construction in the old area, and only the electric heating oil collection process can be used. Electric heating oil gathering technology has gradually developed into an effective technical measure to realize single-pipe oil gathering in low-yield oilfields in severe cold regions, simplify the pro...
