And fishing head is made of guide pin bushing, spring, T shape fishing rod, and spring is installed in the guide pin bushing, and T shape fishing rod is installed in the spring upper end, and guide pin bushing is by back of the body cap and coaxial the installing in standing valve upper end; Inwall at fisher is shaped on the spiral path that clamps described T shape fishing rod.
And, described mechanical locking device is made of a mandrel, locking support ring and locking supported joint, mandrel installs the locking support ring by the coaxial standing valve lower end that is packed in of locking supported joint in the mandrel outer, coaxial, and the outer wall of this locking support ring is an inverted cone; Be shaped on the inverted cone support platform in the inside, upper end of supporting packoff nipple, coaxial being inserted into of mandrel supported in the packoff nipple, and the locking support ring compresses and is installed on the inverted cone support platform.
Advantage of the present utility model and good effect are:
1. the standing valve assembly bottom of this standing valve salvagable oil well pump is a mechanical locking device, standing valve compresses sealing by this mechanical locking device and is installed on the support packoff nipple, it is reliable to connect sealing, the fishing head that install on standing valve top can cooperate with the fisher that the plunger piston assembly lower end installs, and realizes the salvaging to the standing valve assembly.
2. this standing valve salvagable oil well pump scientific structure design is reasonable, having the standing valve assembly removes conveniently, connect the outstanding advantage of reliable sealing, can under the prerequisite of not carrying pump barrel, keep in repair and change standing valve, wander up and down valve, also can carry out operations such as well cleanout and reverse cleanout, wax removal, sand washing, down-hole injection carrier, the interior hollow test of tubing string simultaneously, and manufacturing operation need not to install oil drainer etc., is a kind of oil well pump with high application value.
Description of drawings
Fig. 1 is structural representation of the present utility model (partly cuing open figure).
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of standing valve salvagable oil well pump mainly is made of pump barrel 3, plunger piston assembly, standing valve assembly.Plunger piston assembly is made of plunger 2, upper travelling valve 1 and lower travelling valve 4, and the standing valve assembly comprises a standing valve 12.
The innovation part of this oil well pump is: the standing valve assembly also comprises the mechanical locking device that is packed in the standing valve lower end and is packed in the fishing head of standing valve upper end.Wherein, mechanical locking device is made of a mandrel 16, locking support ring 15 and locking supported joint 14.Mandrel installs the locking support ring by coaxial valve bonnet 13 lower ends that are packed in standing valve of locking supported joint in the mandrel outer, coaxial, and the outer wall of this locking support ring is an inverted cone.Bottom at pump barrel is fixed with support packoff nipple 17 by box cupling 20, is shaped on inverted cone support platform 19 in the inside, upper end of supporting packoff nipple, and coaxial being inserted into of mandrel is supported in the packoff nipple, and the locking support ring compresses and is installed on the inverted cone support platform.The standing valve assembly compresses to be installed in by mechanical locking device and supports the packoff nipple upper end.Be shaped on elastic chuck 18 in the bottom of mandrel.
Fishing head is made of guide pin bushing 10, spring 9, T shape fishing rod 8, and spring is installed in the guide pin bushing, and T shape fishing rod is installed in the spring upper end, and guide pin bushing is by back of the body cap 11 and coaxial the installing in standing valve upper end.At the coaxial fisher 6 that installs in valve bonnet 5 bottoms of the lower travelling valve of the bottom of plunger piston assembly, be shaped on the spiral path 7 that clamps described T shape fishing rod at the inwall of fisher.
Working principle of the present utility model is:
When salvaging standing valve, slowly transfer plunger to bumping pump, make fisher and fishing head change to revolve clockwise and turn 90 degrees, the T shape fishing rod of fishing head is installed in the made spiral chute of fisher inwall, achieves a butt joint.Spring in the fishing head plays buffer function to fisher, avoids damage.When rotating rod string, consider the elastic torsion distortion of sucker rod, the angle of rotating on ground should increase, to guarantee that fisher and fishing head are to connecting.Carry plunger to connecting on the back, the standing valve assembly can propose with the sucker rod roofbolt.But pulling when being lowered to the standing valve assembly, when roofbolt load descended two tons of left and right sides, the standing valve assembly just can be fixed on and support on the packoff nipple, carried sucker rod on slowly again, and fisher and fishing head are thrown off, and regulated over-stroke, can begin to pump.
Go into the well for the first time when using, standing valve has been installed in the pump barrel precalculated position, plunger in lower going-into-well during near the standing valve position (according to the roofbolt length measuring and calculating of pump barrel, sucker rod) slowly transfer, and avoid the roofbolt rotation, transfer put in place after, roofbolt load descends and to be not more than 2 tons and to be advisable.It is suitable that over-stroke will be adjusted, and avoids bumping in the working procedure pump.
