Problems solved by technology

[0003] Because the water content and flow rate of the water-containing crude oil flowing through the quick-opening-recovering spherical tube change with the well conditions, it is difficult to achieve constant temperature heating of the crude oil in the quick-opening-recovering spherical tube

Abstract

The invention relates to a constant temperature control method for a quick-opening and closing bulb, the method comprising the steps of: acquiring the water content and flow rate of the crude oil flowing into the quick-opening and closing bulb at the current sampling time, as the water content and the flow rate at the current sampling time; The water content and flow rate at the current sampling time are compared with the water content and flow rate at the initial sampling time respectively, and the water content change value and the flow rate change value are obtained; based on the water content change value and the flow rate change value, the current sampling time Temperature compensation value; use the temperature compensation value at the current sampling time to compensate the control temperature at the initial sampling time to obtain the control temperature at the current sampling time; heat the quick-opening and collecting cylinder according to the control temperature at the current sampling time. The present invention compensates the control temperature through real-time acquisition of the water content and flow rate of the crude oil flowing into the quick-opening and closing bulb, so as to realize constant temperature heating of the crude oil in the quick-opening and closing bulb.

Description

technical field [0001] The invention relates to the technical field of oilfield ground equipment, in particular to a constant temperature control method and device for quick opening and closing of a bulb. Background technique [0002] The main function of the quick-opening and collecting ball cylinder is the recovery of wax cleaning balls for oilfield pipeline transportation, and it is usually installed in the pressurization point, carry-over station or combined station of oilfield station. If the temperature in the quick-opening and collecting tube is too low, the wax cleaning ball is not easy to be taken out, resulting in the connection with the pipeline wax, and manual cleaning is laborious and laborious. If the temperature in the quick-opening and closing bulb is too high, the crude oil may decompose into combustible gas, posing a safety hazard. The wall of the quick-opening and closing ball cylinder is heated by the electromagnetic induction heating coil, which can eff...
