Description
Affiliated technical field
The utility model relates to a kind of oil well heating power paraffin removal unit that is mainly used in oil field development manufacturing machine oil extraction system field, particularly a kind of can solve effectively deeply buried reservoir, layer thin, deeply take out by force adopt, the oil well heating power paraffin removal unit of stratum serious type of oil well shaft wax deposition problem in debt, be adapted to all kinds of oil wells that day production fluid is lower than 30 tons.
Background technology
At present; the wax deposition phenomenon of oil well is restricting the ordinary production of oil well always; known wax removal technology mainly contains mechanical paraffin removal, heating power wax removal and the clear wax control of chemical agent, but traditional clear anti-wax technique has certain limitation in the use, also is unfavorable for the protection of oil reservoir.The annual oil well in oil field accounts for more than 10% because of the well that wax deposition influences production, although the multiple clear wax control measure of integrated application paraffin removing with chemical method, oil well is produced abnormal situation because of the wax deposition influence and still happened occasionally.Original heating power wax removal technology has the following disadvantages: (1) is not suitable for feed flow deficiency, negative pressure suction oil well.(2) easily oil well is damaged, be unfavorable for the protection of oil reservoir, the injury of oil reservoir is irreversible often.(3) easily cause Ka Jing, lie well and operation.Particularly well depth, layer approach, shake out, take out by force deeply adopt, the oil well of stratum types of formations in debt serious, original clear anti-wax technique is difficult to effectively solve its pit shaft wax deposition problem.
Summary of the invention
For overcome existing heating power wax removal technology be not suitable for feed flow deficiency, negative pressure suction oil well and easily cause Ka Jing, lie well and the defective of operation, the utility model provides a kind of oil well heating power paraffin removal unit, this paraffin removal unit can not only solve the down-hole wax deposition problem of feed flow deficiency, negative pressure suction oil well, and can solve well depth, layer approach, shake out, take out by force deeply adopt, the wax deposition problem of the oil well of stratum types of formations in debt serious, prevent Ka Jing, lie well and operation.
The technical scheme that its technical problem that solves the utility model adopts is: movably on the trailer water jacket furnace is being installed, its liquid feeding end advances pump valve by pipeline and external crude oil, and body of heater hot water advances pump valve, and backflow, pressure regulation, amount adjusting valve and gear pump are connected; Its outlet end constitutes by the pipeline connection.According to designing requirement, water jacket furnace is installed by upper of furnace body and is connected end socket, connect boiler clothing (fire tube) from the bottom of body of heater to vertically installing between the end socket, install between boiler clothing (fire tube) and the body of heater and be connected coil pipe liquid cover, its top design is installed chimney, its underpart design has the coal-fired furnace cavity and the coal feed point of heating usefulness, and body of heater one side is furnished with the blast fan connection that promotes burning and constitutes.Adopt tractor to make tractor, join generating equipment generating or external power supply voluntarily, technological process is simple.Heating power paraffin removal unit emphasis solve deeply buried reservoir, layer thin, deeply take out by force adopt, stratum serious feed flow deficiency in debt, the problem of type control and remove of well paraffin such as stratum negative pressure suction.
The heating power paraffin removal unit is a temperature of utilizing heat energy raising liquid stream and deposition surface, thus the wax of melt deposition in pit shaft.Bottom pressure is no more than ground laminar flow pressure in the hot clean-up well process, has avoided oil reservoir is injured.Discharge capacity is compared little with original hot clean-up well discharge capacity, technical reaching can be brought heat energy into the pit shaft dewaxing, can guarantee that again wax stone can be expelled to ground with liquid stream in the manufacturing process.It is a kind of method in the heating power wax removal type, its principle is to utilize heating power paraffin removal unit heat hot carrier (oil or water), slowly injects pit shaft by the oil jacket annular space, and heat transfer medium is when the oil jacket inventionannulus flow, its heat energy transmits in oil pipe in the mode of heat transmission, improves the temperature of tube inner wall.Along with the raising of pit shaft inner fluid temperature, when temperature surpassed the fusing point of wax, wax just began fusing, and is dissolved in the crude oil, was taken out of to ground with liquid stream, thereby reached the purpose of wax removal.
The utility model paraffin removal from oil well is thorough, the oil well average load can reduce by 1.4%, and electric current descends 0.7%, reduces the well of lying, prolong and be excused from a college course the phase, improve rate when recovering the oil, mechanical system efficient improves, and oil well output rises in various degree, compare with conventional wax removal mode, the clear wax control expense of individual well annual mean has significantly decline, can improve oil extraction system efficient and development management level, obvious social benefit.
