Abstract
The utility model provides a novel wellhead bias adjustment device for an oil pumping unit, wherein a screw thread flange is arranged above the four-way junction of the wellhead, an adapter is positioning connection with a flange through the screw thread flange; an eccentric body is connected with the adapter in an inserting way, and the eccentric body and the adapter are sealed through an O-shaped seal ring; the eccentric body and the adapter are connected, fastened and positioned through union buckle screw threads; when in use, an oil pumping polished rod penetrates the main pipe of the bias adjustment device, and is arranged in the center of the circle of a rubber gate center pipe by rotating the eccentric body. The eccentric wearing problem of the wellhead can be solved by adjusting the inserting position of the eccentric body and the adapter to adjust the eccentric oil pumping polished rod to be positioned in the center of the circle of a packing box and aim at and be placed in the middle of the wellhead. By fully taking into account the actual production of the oil field, the utility model effectively solves the eccentric wearing problem of the wellhead, prevents the pollution caused by wellhead pressure release and crude oil leakage, improves the working environment, reduces the labor intensity of labors, saves the production cost, and has long service life, convenient dismounting and omnibearing bias adjustment.
Description
Technical field
The utility model relates to a kind of new pumping unit well head deviation correcting device, is specifically related to oil pumper well head off-centre, the oil pumping polish rod of off-centre is adjusted to well head aimed between two parties, solves the well head deviation correcting device of eccentric wear.
Background technology
In the oil exploitation of oil field, the most of mode of artificial lift that adopts of the crude oil in the oil reservoir is exploited.The oil pumper sucker rod pumping of one of artificial lift oil production method is the oil production method of current extensive use both at home and abroad.Because equipment is simple, small investment, convenient management, compliance is strong, and sucker rod pumping has obtained using widely.Domestic sucker rod pumping accounts for artificial lift about 90% of the total well number that recovers the oil.The quality that this shows the sucker rod pumping equipment performance has very important effect in field of petroleum exploitation.
The daily management of sucker rod pumping equipment mainly comprises ground oil pumper and well head.The oil pumper well head is not just, off-centre makes oil pumping polish rod eccentric wear packing, causes the packing frequent breakage to be changed, and the well head oil leaking pollution causes great difficulty to management work, and oil pumping polish rod eccentric wear packing box damages polished rod when serious, and packing can't be changed, and causes oil well to stop production.
Therefore, need a kind of good sealing effect, high pressure resistant, simple in structure, easy to use well head deviation correcting device.
The utility model content
The utility model purpose is to solve the problems of the technologies described above, and a kind of new pumping unit well head deviation correcting device is provided, be a kind of install simple, easy operating, can comprehensive adjustment off-centre the well head deviation correcting device, can fundamentally solve oil pumping polish rod eccentric wear problem.
The technical solution of the utility model is: new pumping unit well head deviation correcting device, screw thread flange are arranged on well head four-way top, become the button pipe nipple and are located by connecting by screw thread and screw thread flange; Eccentric body is plugged on and seals by the O RunddichtringO with becoming the button pipe nipple; Eccentric body is detained pipe nipple by detaining the fastening location of screwed connection the oily ninth of the ten Heavenly Stems with change.
Further comprise the rubber gate, the rubber gate is connected with eccentric body by screw thread, and polished rod is positioned at the center of circle of eccentric body and rubber gate central tube, is connected with the down-hole sucker rod by the polished rod box cupling.
Oil pumping polish rod runs through among the person in charge who is arranged on deviation correcting device during use, makes oil pumping polish rod be positioned at the center of circle of rubber gate central tube by the rotating eccentricity body.So the utility model can be adjusted to the center of circle of packing box with the oil pumping polish rod of off-centre by regulating eccentric body and the plug-in position that becomes the button pipe nipple, eccentric oil pumping polish rod is adjusted to well head is aimed between two parties, solution well head eccentric wear problem.
The beneficial effect of this utility model is: this utility model has taken into full account on-the-spot actual condition, can effectively solve well head eccentric wear problem, prevent that well head from putting the pollution that leaks of pressure, crude oil, improved working environment, reduce working strength of workers, saved cost of production, had long service life, convenient disassembly, advantage that can comprehensive tuningout.
Description of drawings
Fig. 1 is a simple structure schematic diagram of the present utility model.
Fig. 2 is the concrete structural representation of implementing of the utility model.
Among the figure: the 1-eccentric body; 2-oil button in the ninth of the ten Heavenly Stems; The 3-O RunddichtringO; 4-becomes the button pipe nipple; 5-screw thread flange;
6-well head four-way; 7-rubber gate; The 8-polished rod; 9-polished rod box cupling; The 10-sucker rod; 11-eccentric body axle center; 12-eccentric body grafting seal section.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
See accompanying drawing 1,2, the well head deviation correcting device is implemented by forming with the lower part:
Screw thread flange 5 is arranged on well head four-way 6 tops, substitute original four-way flange, becoming button pipe nipple 4 is located by connecting by screw thread and screw thread flange, eccentric body 1 is plugged on becoming the button pipe nipple, by 3 sealings of O RunddichtringO, eccentric body is detained the fastening location of 2 screwed connections with becoming the button pipe nipple by oil the ninth of the ten Heavenly Stems, and rubber gate 7 is connected with eccentric body by screw thread, polished rod 8 is positioned at the center of circle of eccentric body and rubber gate central tube, is connected with down-hole sucker rod 10 by polished rod box cupling 9.
Well head deviation correcting device using method of the present utility model is as follows:
The screw thread flange is substituted original four-way flange, be fixed on well head four-way top with the four-way flange bolt, becoming the button pipe nipple is located by connecting by screw thread and screw thread flange, oil pumping polish rod runs through among the person in charge who is arranged on deviation correcting device, measure oil pumping polish rod and depart from the position and the distance at person in charge center, select the eccentric body of suitable distance of shaft centers size, determine eccentric body and the plug-in position that becomes the button pipe nipple, make oil pumping polish rod adjust to the center of circle of rubber gate packing box, the realization oil pumping polish rod is aimed at well head between two parties, by the O RunddichtringO eccentric body is sealed with becoming the button pipe nipple, eccentric body is detained the fastening location of screwed connection with becoming the button pipe nipple by oil the ninth of the ten Heavenly Stems, and rubber gate and eccentric body screw thread are located by connecting.
Require: polished rod box cupling radius size must be less than the minimum range of eccentric body axle center 11 apart from eccentric body grafting seal section 12 inner surfaces.
After this well head deviation correcting device is installed, can keep polished rod, effectively solve well head eccentric wear problem, guarantee rod-pumped well ordinary production and management all the time in the center of well head rubber gate.
