Abstract
The utility model relates to oil field equipment, in particular to an auxiliary device in a mechanical oil recovery method. The improvements of the nylon paraffin scraping device include that a limit device and a nylon paraffin scraper are arranged on a sucker rod, and the limit device and the nylon paraffin scraper are separated. The nylon paraffin scraping device is characterized in that (1), the technique realizes automatic paraffin removal in oil pumping process by utilizing existing oil pumping unit power and a sucker rod in the mechanical oil recovery process to mount the limit device and the nylon paraffin scraper on the sucker rod through special technologies and machines, (2), a paraffin scraping block can centralize and guide the sucker rod, and eccentric wear of the sucker rod and an oil pipeline can be effectively overcome, (3), by utilizing the technique, the paraffin removal and rod-pipeline deviation can be thoroughly overcome in oil production process, an oil producing well does not need work stoppage due to the paraffin removal, and compared with the prior art, the rod-pipeline eccentric wear rate can be reduced by 95%.
Description
Technical field
The utility model relates to a kind of oil field operation equipment, especially relates to the used auxiliary equipment of a kind of mechanical oil production model.
Background technology
The oil field generally is to adopt mechanical oil production model in oil recovery process at present.Mechanical oil recovery utilizes oil pumper exactly, drives downhole pump by sucker rod, pumps, and down-hole crude oil is drawn into ground sends into oil gathering station by oil pipeline.In this process, because the variation of formation temperature, from the well head to the down-hole 1000 meters or more the depths cause the oil pumper load to increase along with the impurity such as paraffin in the reduction crude oil of temperature bond on oil pick-up tube inwall and the sucker rod, sucker rod is blocked, even causes sucker rod to be broken the formation accident.In order to prevent wax card problem, mainly be at present by regularly every mouthful of well being carried out hot water or steam clean or regularly add chemical agent solving.This method has two shortcomings when implementing: one will employ boiler car or medicine adding vehicle, cost height, complex process; The 2nd, must stop production during operation and carry out, influence is produced.
Simultaneously, because the particularity that the nylon wax scraping apparatus is produced does not also have special production equipment in the market.
Summary of the invention
The purpose of this utility model just provides a kind of novel nylon wax scraping apparatus, has characteristics simple in structure, easy for installation, effective wax removal.
For achieving the above object, the utility model adopts following technical scheme: this nylon wax scraping apparatus, its improvements are: be provided with stop, nylon paraffin scraper on sucker rod, and described stop and nylon paraffin scraper are to be provided with at interval.
Further improvement in the technical proposal is: described nylon paraffin scraper external surface is provided with groove, also is provided with an opening on the described nylon paraffin scraper.
Further improvement in the technical proposal is: the groove that described nylon paraffin scraper external surface is provided with is oblique.
Further improvement in the technical proposal is: the opening that described nylon paraffin scraper is provided with is an angle.
The utility model nylon wax scraping apparatus has following characteristics: 1. this technology is utilized existing oil pumper power and sucker rod in the mechanical oil recovery process, nylon stop and nylon paraffin scraper are installed on the existing sucker rod by special process and machine, have realized wax removal operation automatically in the process of oil pumping.2. scrape wax stone and also play, solved the eccentric wear problem of sucker rod and oil pick-up tube effectively the setting upright and guide effect of sucker rod.3. by this The Application of Technology, thoroughly solved wax removal and rod tube skew problem in the oil recovery manufacturing process, producing well can not stopped work because of the needs wax removal, and the rod and tube partial-wear rate descends 95% than former technology.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Of the present utility model being constructed as follows: on original every sucker rod 1, install several stops 2 at a certain distance.As shown in Figure 1, stop 2 is 5 cylinders that are fixed on the sucker rod 1.The effect of stop 2 mainly is to be limited to activity in certain scope being installed in two nylon paraffin scrapers 3 between the stop 2, makes the nylon paraffin scraper 3 in the whole well bucket distribute more even.Respectively there is a stop sheath 4 (as shown in Figure 5) at the two ends of stop 2, and mid portion dips in glue with nylon yarn and twines, and the effect of stop sheath 4 mainly is the smooth and increase abrasion resistance that guarantees that stop 2 two ends nylon yarns twine.By the stop 2 tensile strength height of making of this bonding way, peel strength 〉=5KN.
The structure of nylon paraffin scraper 3 adapts to the oil well condition condition, is convenient to install change, shown in Fig. 2,3,4.The general shape of nylon paraffin scraper 3 is a cylinder, and there is oblique groove on its surface, the oily wax in can more effective removal oil pipe when sucker rod 1 is pumped in oil well.For the ease of installing, nylon paraffin scraper 3 is provided with an opening, and its opening also is an angle.The advantage of doing like this is, paraffin scraper 3 is set upright after being installed on the sucker rod 1, wait sucker rod 1 time in the well after, under oil pipe surrounded, nylon paraffin scraper 3 just can not come off.And the abrasion resistance of nylon paraffin scraper 3 is good, and the high temperature resistance corrosion resistance is strong.
Fig. 6 is to Figure 9 shows that the special equipment of manufacturing stop 2.This special equipment is to manufacture stop and development and design at installing specially on sucker rod.It can be finished the installation of several stops 2 that are provided with simultaneously and make on a sucker rod 1.Simultaneously, form the desired geometry of design automatically.Fig. 6,7,8 is depicted as the dynamical system of winding machine, and its effect is to drive sucker rod 1 rotation.Figure 9 shows that operating desk, operating desk has five, can make five stops 2 simultaneously.
