Description
Technical field
The utility model relates to a kind of tubing pump blowout hookup, belongs to tool in oil well, is particularly useful for flowing well and the oily down-hole pump blowout hookup technical field having overflow.
Background technology
At flowing well and have in the oily down-hole pump work progress of overflow, under many employings double-plunger pipe type spray-proof oil-well pump, pump oil pumping is produced, this oil well pump contains the blowout hookup be made up of spring retaining mechanism, ball-and-seat, fixed ball seat, by the valve of the tight ball-and-seat of spring locking mechanism lock, realize blocking gas channel, avoid borehole fluid to overflow the object of tubing string.In lower pump work progress, leak for avoiding the excessive crowded flat tube post of tubing string inside and outside differential pressure or causing screw thread to sting, generally take the mode of perfusion fluid in oil pipe, in order to reduce tubing string inside and outside differential pressure.When pressure in tubing string is greater than tubing string external pressure, or tubing string is under lower brill inertia impact, and because the coupling mechanism force of locking spring is limited, locking position thrown off by the steel ball that easily results in blockage, and opens gas channel, causes midway to block failure, the lower pump construction safety of impact.
For the construction well that wax deposition is more serious, namely allow to realize the normal lower anti-spraying construction of pump, but in lower pump process, because the high viscosity wax in pit shaft or in tubing string enters the position of ball-and-seat, easy bonding valve ball, causes gas channel normally to open, and affects the normal work of tubing pump.
Utility model content
The purpose of this utility model be the spring retaining mechanism existed in lower pump process to overcome above-mentioned prior art easily lost efficacy, affect under pump construction safety and affect the defect of normal work of tubing pump, a kind of tubing pump blowout hookup is provided.
The technical solution of the utility model is:
A kind of tubing pump blowout hookup, be made up of standing valve assembly, top connection (4), central tube (8), lower contact (12), the valve ball (2) of standing valve assembly is placed in its valve cover (1), its valve ball seat (3) is embedded between valve cover (1) and top connection (4), and valve cover (1), top connection (4), central tube (8), lower contact (12) are threaded successively; Top connection (4) top has the stepped central through hole that diameter is less than lower diameter, installs the push rod blocking valve core assembly of blocking in top connection (4) lower central through hole;
By falling, " T " font push rod blocks spool (5) to described push rod blocking valve core assembly, valve pocket (6) forms, and valve pocket (6) is circulus, is threaded in the central through hole of top connection (4) bottom; It is pallet that " T " font push rod that falls blocks spool (5) upper end, and lower end is fixed by a pin in valve pocket (6), and the height of its push rod is greater than the height of top connection central upper portion through hole;
The reception locking device of " T " font push rod blocking spool (5) is provided with down in described lower contact (12) central through hole;
Described reception locking device comprises reception guide rod (7) and locking shell fragment (9), the cross section of locking shell fragment (9) is circulus, longitudinal section is dumbbell-shaped structure, its outer wall has flow channels (11), locking shell fragment (9) lower end is threaded in the central through hole of lower contact (12), and its upper end center through-hole wall is processed as lock tooth; Receive guide rod (7) upper end with fall " T " font push rod and block spool (5) lower end and be threaded, lower end be plugged on lock shell fragment (9) central through hole in;
Fall between " T " font push rod blocking spool (5) and valve pocket (6) faying face and O-ring seal is installed.
The utility model result of use: the utility model better can solve tubing string blowout prevention in flowing well or overflow down-hole pump work progress, can realize again tubing pump normally pump produce construction requirement, this blowout hookup structure is simple, easy to operate, dependable performance, may be combined with into the anti-jetting oil pump of different size model, meet the needs that different oily down-hole pump is produced.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Below in conjunction with drawings and Examples, the utility model is further described.
Detailed description of the invention
As shown in Figure 1, the utility model is made up of standing valve assembly, top connection 4, central tube 8, lower contact 12, the valve ball 2 of standing valve assembly is placed in its valve cover 1, its valve ball seat 3 is embedded between valve cover 1 and top connection 4, and valve cover 1, top connection 4, central tube 8, lower contact 12 are threaded successively; Top connection 4 has the stepped central through hole that upper diameter is less than lower diameter, installs the push rod blocking valve core assembly of blocking in top connection 4 lower central through hole.
By falling, " T " font push rod blocks spool 5 to described push rod blocking valve core assembly, valve pocket 6 forms, and valve pocket 6 is circulus, is threaded in the central through hole of top connection 4 bottom; It is pallet that " T " font push rod that falls blocks spool 5 upper end, and lower end is fixed by a pin in valve pocket 6, and the height of its push rod is greater than the height of top connection central upper portion through hole; Fall between " T " font push rod blocking spool 5 and valve pocket 6 faying face and O-ring seal is installed.
The reception locking device of " T " font push rod blocking spool 5 is provided with down in described lower contact 12 central through hole.
Described reception locking device comprises reception guide rod 7 and locking shell fragment 9, the cross section of locking shell fragment 9 is circulus, longitudinal section is dumbbell-shaped structure, its outer wall has flow channels 11, locking shell fragment 9 lower end is threaded in the central through hole of lower contact 12, and its upper end center through-hole wall is processed as lock tooth; Receive guide rod 7 upper end with fall " T " font push rod and block spool 5 lower end and be threaded, lower end be plugged on lock shell fragment 9 central through hole in.
Described reception guide rod 7 upper end is provided with the card tooth cooperatively interacted with the lock tooth of locking on shell fragment 9 central through hole inwall.
During for flowing well, overflow well pipe type pump oil pumping construction, the utility model is connected to tubing pump lower end, the standing valve assembly of former tubing pump is substituted by the standing valve assembly of the utility model upper end, utilize the pallet of " T " font push rod blocking spool 5 upper end to be held up by the valve ball 1 of standing valve assembly, make standing valve assembly be in opening; Utilize " T " font push rod blocking upper surface, spool 5 bottom and top connection 4 centre bore lower surface to seal, by falling the sealing of O-ring seal that " T " font push rod blocking spool 5 lower side installs additional and valve pocket 6, central through hole in blocking top connection 4, avoid oil, gas, water and high viscosity wax to enter the pump barrel of tubing pump, realize lower tubular column construction blowout prevention function; Utilizing shear pin will fall " T " font push rod blocking spool 5 is fixed in valve pocket 6, and adjustment shear pin is cut off pressure to set up and opened retaining pressure.
When tubing pump is down to projected depth, forehand pressure in tubing string, cuts off down the fixing pin of " T " font push rod blocking spool 5 and valve pocket 6, " T " font push rod blocking spool 5 that falls is descending, open central bore passage in top connection 4, meanwhile, valve ball 2 falls in valve ball seat 3.The descending process of " T " font push rod blocking spool 5, the reception guide rod 7 that its lower end connects to insert in locking shell fragment 9 that bottom receives locking device and is locked, prevent from down " T " font push rod to block spool 5 to reset or descending, now, in well, liquid central through hole in lower contact 12, the locking flow channels 11 of shell fragment 9, top connection 4 enters pump barrel, realizes tubing pump and normally to pump production object.
