Technical Field
The utility model relates to a malleation converter technical field specifically is malleation converter.
Background
In domestic oil exploitation, the proportion of heavy oil is large, and especially for offshore platforms and low-temperature oil layers, when crude oil flows in a shaft, the shaft loses heat quickly, so that the crude oil is solidified and cannot flow (for example, wax generated in oil production and gas production of offshore platforms, and heat loss of seawater below a seabed mud surface and above the mud surface is quick).
At present, the most extensive and best-effect oil extraction technology for exploiting such oil wells at home and abroad is heavy oil thermal recovery. The hollow rod electric heating process technology is adopted to heat crude oil in the oil pipe in the whole process, so that the viscosity of the crude oil is reduced, wax precipitation in the oil pipe is prevented, and the fluidity of the crude oil is improved. Effectively solves various technical problems encountered in the process of extracting the crude oil with high coagulation, high viscosity and high wax content, and achieves the purposes of increasing the yield and the efficiency of the oil well.
The hollow rod electric heating process equipment is generally an oil extraction system aiming at up-down pumping operation, but for a screw pump oil extraction system, because rotation and well head positive pressure explosion protection are needed, no good equipment support exists at present.
For a screw pump oil production system, an offshore platform and a low-temperature oil layer are difficult problems in the production process, and due to the characteristic of fast heat dissipation in sea operation, in order to increase the pump efficiency, thick oil flowing into a shaft needs to be heated so as to reduce the viscosity, prevent wax deposition and facilitate flowing. The common hollow rod electric heating device can only heat the part above the stator of the screw pump, and the part below the pump can not be electrically heated due to factors such as rotation and the like.
