Description
The utility model relates to whale in the oilfield exploitation manually or the oil pipe paraffin scraper in the motor machine wax removal instrument.Adopt the coupling mechanism of hurdling between the ring-type tongue type paraffin scraper of this paraffin scraper and the connecting rod, be mainly used in the conventional mechanical wax removal of whale plain tubing and minor diameter tubing, the de-plugging instrument when also can be used as the oil pipe paraffin blockage simultaneously.
In the Production Wells process,,, even can cause paraffin blockage oil pipe accident, therefore need regular wax removal if untimely removing will influence ordinary production in the continuous wax deposition of tube inner wall.In the at present domestic whale mechanical paraffin removal, never be improved as this key tool of paraffin scraper, that adopts so far remains so-called " 8 " font paraffin scraper thereby wax removal weak effect, fall, the card accident is many, manipulate loaded down with trivial details situation and also never change.Its main cause is: on structure, figure of eight paraffin scraper is an asymmetric body, on, following two points of a knife are in the same side, waist deflection opposite side, middle vertical figure of three opening in addition, adopt " nose " coupling mechanism that is fixed on two ends in the paraffin scraper between connecting rod and the paraffin scraper, run into the too much waist of the serious or movable number of times of wax deposition will flexural deformation and diameter shrink and diminish, on processing technology, because paraffin scraper all is a shaped form, need be along the curve shaping of punching continuously, all curved edges all put the first edge on a knife or a pair of scissors, and particularly putting the first edge on a knife or a pair of scissors needs be deployed into certain degree to paraffin scraper from waist " 3 " shape opening part, be rasped to fully by hand, operation is inconvenience quite, also will recover circular at last, makes original circularity suffer to a certain degree destruction.On result of use, in order to prevent when playing paraffin scraper to cause expanded in diameter to be inverted lock of tool drilling, must be adjusted into big end down awl tubular to paraffin scraper before going into the well because of inner wax deposition or stifled wax, can not put upside down use.In addition for preventing that two points of a knife in the same side from hanging tag in tubing coupling place, end must curve inwardly an angle, i.e. so-called " lead angle ".On paraffin cutting mechanism, when descending paraffin scraper, the wax that scrapes off is cylindric, by the paraffin scraper of taper tubular, wax will paste tighter and tighter at the paraffin scraper inwall, is difficult to pass through smoothly, two connections " nose " of adding in the paraffin scraper form obstacle, and wax is therefrom by just more difficult.When playing paraffin scraper, also there is not the wax stone of ejection can more than paraffin scraper, pile up again in the pit shaft, form so-called rod wax.In a word, it is the wax removal weak effect that above-mentioned reason has all caused paraffin scraper and oil pipe seriously to misfit, inner easily wax deposition and paraffin blockage, and it is big to remove resistance, falls the many basic places of card accident.Although in the wax removal operation, stipulated: will check before and after the wax removal, slowly remove, diligent movable, many waxings, meeting card can not dial firmly, play the preceding first wax spray of paraffin scraper, and regularly " attacking wax " (promptly removes paraffin scraper continuously repeatedly on same well, the clear clean method of remaining wax in the oil pipe) wait an operating process of overlapping very complicated, but situation is not improved at all.(with reference to Science Press's version in 1976, Daqing oil field paraffin removal from oil well and wax control are write " oil machinery wax removal " joint of organizing in " paraffin removal from oil well and wax control " book of writing in the universal book series of oil exploration and exploitation).
Along with the development of development technology in oilfield, this wax removal instrument can not adapt to fully and satisfy and guarantee the whale ordinary production, the needs that improve oil well output and raise the management level, " the tongue type paraffin scraper " of the utility model design, novel structure designs ingeniously, is convenient to machine production.Paraffin scraper and connecting rod adopt the coupling mechanism of hurdling.Its purpose is: for the whale mechanical paraffin removal provides a kind of wax removal effective, and processing and easy and simple to handle, safe and reliable, durable in use, stable performance is not only applicable to the paraffin scraper of the conventional wax removal of plain tubing and minor diameter tubing.But also can be used as the instrument of removing the oil pipe paraffin blockage, be desirable multi-functional oil pipe paraffin scraper.Thereby overcome limitation, unreliability and the unicity of traditional figure of eight paraffin scraper.
Technical characterictic of the present utility model is:
1, the structure of type paraffin scraper is to adopt the coupling mechanism of hurdling between paraffin scraper and the connecting rod, thereby makes the paraffin scraper can be along connecting rod upper and lower activity and freely rotating in restricted portion.
2, paraffin scraper ligulate in the form of a ring, respectively there is the ellipse arc point of a knife of a pair of symmetry at two ends, and are 90 ° mutually, and the opening blade is arranged in the curved edge of two ends.Waist four strips, parallel to each other and be mutually 90 ° all be with the connecting rod axle and the symmetry.
3, be fixed on the hurdling of two center band circular holes at paraffin scraper two ends.
4, the connecting rod middle part have two fixedly gate rings with certain distance and between the star activity in cutter.
Accompanying drawing 1 is a tongue type paraffin scraper and the figure that connects of kit.
Accompanying drawing 2 is the vertically whole and transverse waist sectional drawings of tongue type paraffin scraper.
Be described further below in conjunction with accompanying drawing:
As can be seen from Figure 1, the connecting rod top that is lowered to the paraffin scraper (2) in the oil pipe connects wax removal steel wire (1), and the bottom connects plummet (weighted lever) (3).It is the kit of paraffin scraper.
As can be seen from Figure 2, tongue type paraffin scraper (9) and connecting rod (5) are to connect by (6) (11) of hurdling, connecting rod passes from the center hole of hurdling, there are two fixedly gate rings (7) (10) at two in the middle of coupling ring (4) (12) is arranged, and cutter (8) in the star activity is arranged between (7) (10).Paraffin scraper can be movable and freely rotates in restricted portion along connecting rod, cutter (8) can be between (7) (10) upper and lower activity and freely rotating, the while again can be under the drive of gate ring in paraffin scraper upper and lower activity with freely rotate.
Concrete enforcement:
When one, being applied to conventional wax removal, at first select corresponding paraffin scraper for use according to tubing diameter.Its diameter is detected and proofreaies and correct before going into the well, require paraffin scraper two ends diameter identical and make it and the tube inner wall gap suitably coincide mutually.Can in micro-scope, proofread and correct if the gap is improper.Method is: when the gap was big, two ends are hurdled to be expanded outwardly simultaneously, when gap hour, can satisfy the demand the two ends inwardly compression of hurdling simultaneously.Be regardless of upper and lower can the transposing arbitrarily during use.If when the conventional wax removal of the not serious special work of oil well paraffinication uses, can select the paraffin scraper of not being with cutter in the star activity for use.
Paraffin scraper when two, being applied to remove the oil pipe paraffin blockage will be selected the paraffin scraper that has cutter in the star activity for use, and effect can surpass traditional what is called " spiral bit " de-plugging instrument.Its implementation method, all identical as detecting, proofread and correct, remove method with " implementing one ", different is: paraffin scraper can be hampered behind the wax deposition section top down stop descending, at this moment need movable repeatedly on the ground compressed steel silk, make the paraffin scraper connecting rod drive fixedly gate ring and two collisions mutually of hurdling repeatedly, can be descending gradually, the wax that enters in the paraffin scraper is smashed to pieces by cutter in the star activity again, and by paraffin scraper to more than the paraffin scraper.Continuation activity compressed steel silk, paraffin scraper just can pass through the paraffin blockage section, and the wax stone that scrapes off is taken out of outside the oil pipe by oily stream.Because this paraffin scraper can make wax pass through smoothly,, can not cause crown drill yet and fall the card accident so wax removal rises, the long-pending wax in inside is not with wax in the process down, thereby in the de-plugging process, needn't trip out waxing.If last time-out resistance increases, but the limit active edges rise, if the activity effect not quite can continue up to dial, when steel wire pulling force acquired a certain degree, paraffin scraper shrank voluntarily, eliminated resistance, and paraffin scraper is played well head smoothly.
