Abstract
Disclosed is a pumping well oil tube paraffin knife. The pumping well oil tube paraffin knife comprises a connecting rod, a paraffin-scraping cover and a joint, wherein the paraffin-scraping cover is sleeved on the connecting rod. An external thread of the lower portion of the connecting rod is connected with an internal thread of the joint, an inner diameter of the paraffin-scraping cover is smaller than an outer diameter of the connecting rod, and an inner diameter of the paraffin-scraping cover is smaller than an outer diameter of the joint. The upper portion of the paraffin-scraping cover is provided with an oil outlet groove, the upper portion of the connecting rod is provided with a sucker rod male thread, and the lower portion of the joint is provided with a sucker rod female thread. The pumping well oil tube paraffin knife is arranged between the sucker rods, and can scrape paraffin on the inner wall of the oil tube when the sucker rods move upwards and downwards in the oil tube, and therefore the pumping well oil tube paraffin knife can remove paraffin anytime in a production process, and is low in paraffin removing cost and good in economic benefit.
Description
Technical field:
The utility model relates to the process units that producing well is used, and is a kind of pumpingh well oil pipe paraffin scraper.
Background technology:
Producing well in process of production, when well head flowed, the well temperature descended gradually from the shaft bottom for oil stream, when being lower than wax precipitation point, wax contained in the crude oil will be separated out, and stops up oil flow channel, influences oil well production, need carry out wax removal to oil well and just can make the oil well ordinary production.Existing dewaxing method is more, and a kind of is that the hot water circuit well-flushing flows out the wax dissolving, but the low well of strata pressure is not suitable for the hot water circuit well-flushing, because the low well of strata pressure can not form circulation, hot water can get into the stratum and cause oil layer pollution; Another kind is in oil well, to add the wax removal Ji, and this method cost is high, and overhead cost are high, and are less economical.
Summary of the invention:
The purpose of the utility model is a kind of pumpingh well oil pipe paraffin scraper of design, makes things convenient for paraffin removal from oil well, reduces the paraffin removal from oil well expense.
The purpose of the utility model is achieved in that and comprises connecting rod, paraffin cutting cover, joint; The paraffin cutting cover is sleeved on the connecting rod, and the connecting rod lower external thread is connected with the joint internal thread, and the internal diameter of paraffin cutting cover is less than the external diameter of connecting rod; The internal diameter of paraffin cutting cover is less than the external diameter of joint; Paraffin cutting cover top has out oil groove, and there is the sucker rod male thread connecting rod upper end, and there is the sucker rod box thread joint lower end.
The beneficial effect of the utility model is: the utility model is installed between the sucker rod, with sucker rod in oil pipe during up-downgoing, the wax on the scraping tube inner wall, therefore, the utility model can be in process of production wax removal at any time, the wax removal expense is low, and is good in economic efficiency.
Description of drawings:
Fig. 1 is the assembling drawing of the utility model embodiment.
The specific embodiment:
Below in conjunction with Fig. 1 the utility model embodiment is described.Comprise connecting rod 1, paraffin cutting cover 2, joint 3, paraffin cutting cover 2 is sleeved on the connecting rod 1, and connecting rod 1 lower external thread is connected with joint 3 internal threads; The internal diameter of paraffin cutting cover 2 is less than the external diameter of the large-diameter portion under the top male thread of connecting rod 1, and paraffin cutting cover 2 can not deviate from from connecting rod 1, and the internal diameter of paraffin cutting cover 2 is less than the external diameter of joint 3; Paraffin cutting cover 2 can not deviate from from joint 3, and paraffin cutting overlaps 2 tops and has out oil groove 4, with sucker rod when descending; After paraffin cutting overlaps 2 upper surfaces and connecting rod 1 top large-diameter portion contacts; Oil can be discharged from going out oil groove 4, guarantees flow channels, and there is the sucker rod male thread connecting rod 1 upper end; There is the sucker rod box thread joint 3 lower ends, so that be installed on the sucker rod.
