Abstract
The utility model relates to a universal guide device for a sucker rod, which is used for production and downhole operation of an oil pumping well. The utility model is composed of an upper joint 1, a guide sphere 2, a spherical cover 3, a stop pin 4 and a lower joint 5. The device has the advantages of novel design simple structure and reliable performance. The utility model can not only prevent a sucker rod shedding, but also satisfy the complex and multivariant operating conditions that well bores of an oil well and an oil pipe are bent and operating requirements. The utility model accomplishes the functions of offset adjustment, guide, abrasion reduction, etc. The utility model prolongs the production period of an oil pumping well.
Description
The utility model relates to a kind of downhole tool that is used for pumping well production and underground work: the pumping rod universal guider.
The sucker rod anti-drop device is one of pumping well downhole tool commonly used.Though conventional sucker rod anti-drop device can reach the anticreep effect in application, but its performance is single, structure is optimized inadequately, can only radially rotate, and can not axially curve, thereby in the pumping well production process, particularly exist under the crooked situation at pit shafts such as inclined shaft, directional well, oil pipe, bending, tuningout, leading role can not be realized, rod string proper functioning under the works fine state can not be guaranteed.Even straight well under the situation of feed flow deficiency, liquid hit phenomenon also often takes place, can produce the bending failure effect to sucker rod.Existing sucker rod anti-drop device does not possess protection or alleviates the function that rod string bears the bending failure effect owing to structural limitation.
The purpose of this utility model is to provide a kind of sucker rod that guarantees can and turn, can play the pumping rod universal guider that the anticreep effect can be made axial bending realization tuningout again, lead, avoids eccentric wear to any direction rotation arbitrarily at work.
The utility model is to realize like this.This device is made up of upper connection, guiding spheroid, spherical cap, retaining pin and lower contact, its structure, assembling feature are as follows: guiding spheroid top places to be attached thereto in the upper connection and by screw thread and connects, the spherical cavity that the bottom places spherical cap and lower contact to connect and compose is indoor, for being threaded, be respectively equipped with the retaining pin of preventing that the retaining button is used in upper connection and guiding spheroid top, spherical cap and the corresponding pin hole of lower contact connection part between spherical cap and the lower contact.The number that the universal guider of this kind is used is decided according to the number of pumping well pit shaft bending point, and with the rod string G.I.H, can make sucker rod placed in the middle in oil pipe, carry out effects such as tuningout, guiding, turning randomly by universal guider, smooth and easy operation when guaranteeing the rod string up-downgoing, in oil pipe, be in best working state, thereby reach the purpose that reduces wear, reduces various infringements, prolongs the oil well production cycle.
The utility model modern design, simple in structure, reliable performance, utilize it not only can play the effect of sucker rod anticreep, also can satisfy well wellbore, tubing bending, operating mode and usage requirement complicated and changeable, realize functions such as tuningout, guiding, anti-attrition, prolong the pumping well manufacture cycle, be suitable for and apply.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model is made up of upper connection 1, guiding spheroid 2, spherical cap 3, retaining pin 4 and lower contact 5.Wherein upper connection 1 is hollow body, and its upper end is the rod collar screw thread, and the lower end is regular screw threads, and is drilled with a lateral pins hole.Lower contact 5 is the filled circles body of rod, and hemispherical groove is made in its upper end, and periphery is threaded, and is drilled with a lateral pins hole, and the middle part is provided with shoulder, lower end band sucker rod screw thread.Guiding spheroid 2 tops are cylindrical body, and the upper end is threaded, and is drilled with a lateral pins hole that matches with upper connection, and the bottom is a spheroid, and the centre is an axle journal.Spherical cap 3 is a cylindrical body, and the top inner headed face is made hemisphere face, and the bottom is provided with internal thread, and is drilled with a lateral pins hole that matches with lower contact.
