Abstract
The utility model relates to an oil development well head device, in particular to novel abrasionproof device is right to sucker rod. The technical scheme is as follows: including sucker rod joint (1), the body of rod (4) and right body (3), characterized by: the upper end and the lower end of the righting body (3) are respectively connected with the sucker rod joint (1) and the rod body (4), the righting body (3) is spherical, and guide grooves (2) penetrating through the spherical righting body (3) are formed in the two sides of the righting body (3). The utility model has the advantages that: the sucker rod is provided with the spherical device, so that the position of the centralizing and anti-abrasion device can be automatically selected according to the deformation degree of the underground oil pipe and the friction resistance of the inner surface of the oil pipe, and the effects of prolonging the service life of the centralizing body and centralizing the rod body are achieved.
Description
One, technical field:
The utility model relates to a kind of oil exploitation wellhead assembly, particularly a kind of novel sucker rod righting anti-abrasion device.
Two, background technology:
Existing oil pumper shoe, as nylon abrasionproof device, weighted lever, rotation well head, draw anchor and inclined shaft pump tool etc., the problem of its existence is: the descending difficulty of roofbolt often, the premature failure that causes the abrasionproof device, cause the eccentric wear well to be excused from a college course the phase weak point, labour intensity is big, the cost height.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of premature failure and short novel sucker rod righting anti-abrasion device of life cycle that has solved the abrasionproof device is provided.
Its technical scheme is: comprise rod connector (1), the body of rod (4) and centralizer body (3), it is characterized in that: described centralizer body (3) two ends up and down connects with the rod connector (1) and the body of rod (4) respectively, described centralizer body (3) is spherical, and described centralizer body (3) both sides are provided with the guiding gutter (2) that runs through spherical centralizer body (3).
The beneficial effects of the utility model are: at sucker rod spherical device is set, the position of righting anti-abrasion be can select according to the size of the frictional resistance of down-hole oil tube deformation extent and pipe inner surface voluntarily, application life that prolongs centralizer body and the effect of setting upright the body of rod played.
Four, description of drawings:
Accompanying drawing 1 is a sectional view of the present utility model.
Five, the specific embodiment:
In conjunction with the accompanying drawings, the utility model will be further described:
Its technical scheme is: comprise rod connector 1, the body of rod 4 and centralizer body 3, wherein, described centralizer body connects with the rod connector 1 and the body of rod 4 respectively at two ends about in the of 3, the body of rod 4 lower ends connect lower contact 6, described centralizer body 3 is spherical, and described centralizer body 3 both sides are provided with the guiding gutter 2 that runs through spherical centralizer body 3.
Wherein, centralizer body is injection molded for strengthening nylon six, and is embedded with guiding gutter, according to eccentric wear position, well section, eccentric wear degree and the pipe of oil well, the requirement of roofbolt optimal design, can many combination connections be lowered to, also can be lowered to sucker rod or weighted lever cross-join.
The body of rod and centralizer body endoporus have all been done the drag reduction technology and have been handled, friction factor is very little, make that the wearing and tearing that produce between the body of rod and the wiper block are very little in liquid, thereby set upright the body of rod, prevent to produce contact friction between sucker rod and the oil pipe, prolong the effective storage life of centralizer body in oil pipe, improve the oil pumper operation condition.
Test at Shengli Oil Field ST1-1-41 and the aboveground employing the utility model of western ST1-1-76,, brought up to 150 days respectively and 120 days by existing life cycle 58 days.
Claims (1)
1, a kind of novel sucker rod righting anti-abrasion device, comprise rod connector (1), the body of rod (4) and centralizer body (3), it is characterized in that: described centralizer body (3) two ends up and down connects with the rod connector (1) and the body of rod (4) respectively, described centralizer body (3) is spherical, and described centralizer body (3) both sides are provided with the guiding gutter (2) that runs through spherical centralizer body (3).
