Description
Technical field:
The utility model relates to oil exploitation down-hole mechanical field, is specifically related to a kind of oil recovery wax control apparatus for eliminating sludge.
Background technology:
Generally all wax is contained in crude oil, China has many oil fields paraffin content very high, when oil producing operation, crude oil from the process of subsurface to surface because temperature constantly reduces, wax in crude oil can be separated out and be condensed on sucker rod and tube wall after temperature reaches wax precipitation point (generally at about 40 DEG C), oil pumping operation is finally caused to stop, must remove by " well-flushing " wax solidified and could continue oil pumping, Paraffin Removal becomes the important technical links of crude oil production, and oil pick-up tube is easily leaked, need to stop oil producing operation and after experiencing the maintenance of a couple of days, just can restart operation of pumping, have a strong impact on the production efficiency of crude oil.
Utility model content:
The purpose of this utility model is just to provide a kind of oil recovery wax control apparatus for eliminating sludge to solve the problem, and efficient solution can decide oil screen pipe, clear cured scale removal.
In order to solve the problem, the utility model provides a kind of technical scheme: a kind of oil recovery wax control apparatus for eliminating sludge, comprises top connection, tube connector and lower contact; Described top connection is threaded connection at tube connector epimere; Described lower contact is threaded connection at tube connector hypomere; Its innovative point is: also comprise fastening devices, upper bearing (metal), flight, wax control compo pipe, heating rod, lower bearing and lower fastening devices; Fixed device is positioned at below top connection, and fixed device is fixedly connected with tube connector by screw thread; Described upper bearing (metal) is coated in fastening devices; Described wax control compo pipe is under upper fastening devices between fastening devices, and described wax control compo pipe is coated in tube connector, and described wax control compo pipe two sections is provided with several heating rod; Described lower fastening devices is positioned at above lower contact, and described lower fastening devices is fixedly connected with tube connector by screw thread; Described lower bearing is coated in lower fastening devices; Described flight is between upper fastening devices and lower fastening devices, and described flight is fixedly connected in upper bearing (metal) and lower bearing and rotates.
As preferably, fixed device and lower fastening devices are provided with several hole.
As preferably, described tube connector two sections is provided with internal thread.
As preferably, described upper bearing (metal) and lower bearing are deep groove ball bearing.
The beneficial effects of the utility model: the utility model structure is simple, compact and reasonable, fast easy to assembly, connect reliable, the utility model can avoid fuel-displaced screen casing and oil well pump each position fouling and clogging up and down, increases oil well oil pump capacity, improve the recovery ratio in oil field, effectively can be removed wax deposition, the scale problems of outer barrel by the flight on central tube, ensure that the long-term normal of underground equipment runs, the extension device time between overhauls(TBO), save plant maintenance and the cost of overhaul, improve output efficiency.
