Description
Technical field
The present invention relates to a kind of oil exploitation well sand preventing tool, particularly a kind of rotary location tool for single multilayer gravel pack tools.
Background technology
Crude oil flows into the process of pit shaft from stratum, can carry some sand grains and enter pit shaft.For preventing sand production, on the one hand will for oil reservoir and oil well condition, selecting properly well cementation, completion mode, formulate and reasonably exploit measure, raise the management level; On the other hand, corresponding anti-sand method to be adopted according to oil reservoir, oil well and the concrete condition of shaking out.Current anti-sand method, mainly contains the method such as mechanical technology sand control, chemical sand control, sleeve pipe outer inflatable packer sand control, gravel filling sand prevention.
In existing gravel pack methods, the general mode of carrying out individual layer sand control, successively sand control that adopts carries out multiple gravel pack, and field operation needs repeatedly to enter instrument down, duty cycle is long, and operator's labour intensity is large, and sand control treatment speed is slow simultaneously, big energy-consuming, high in cost of production problem.
In single multilayer gravel-packing process, make the pack hole on filling crossover tool and the filling corresponding aperture on sliding sleeve often can not aim at alignment function difficulty in other words comparatively large, and waste time and energy; Even if make the pack hole on filling crossover tool aim at complete with the filling corresponding aperture on sliding sleeve through great efforts, but because pressure is excessive in stowing operation, service aid can move up, thus there will be the problems such as location is inaccurate.
Summary of the invention
The object of the invention is to solve prior art Problems existing and deficiency, the rotary location tool of the application of the invention, can make the pack hole on filling crossover tool better aim at the filling corresponding aperture on sliding sleeve when filling; Even if when stowing pressure is excessive, by the location of rotary location tool of the present invention, also can prevent from service aid moves to service aid pressurization.
Rotary location tool of the present invention, it comprises top connection and lower contact, its special feature is: be provided with interconnective guide peg and central tube between described top connection and described lower contact, described guide peg lower end is provided with outside fix step, the flexible positioning sleeve of described guide peg arranged outside, the arranged outside of described central tube has guide cylinder, described elastic locating sleeve is connected with inside and outside described outside fix step, described elastic locating sleeve is connected up and down with described guide cylinder, described central tube is provided with J type groove, described guide cylinder is provided with elongated slot, described J type groove is connected with cylindrical pin, the other end of described cylindrical pin is flexibly connected with described elongated slot.
In order to improve prior art further, the special feature of rotary location tool of the present invention is also: described guide peg arranged outside has energizing spring, and described energizing spring is between described top connection and described elastic locating sleeve.
In order to improve prior art further, the special feature of rotary location tool of the present invention is also: described elastic locating sleeve is provided with outer lug boss, and the inner side of described outer lug boss is flexibly connected with described outside fix step.
In order to improve prior art further, the special feature of rotary location tool of the present invention is also: described elastic locating sleeve upper end is provided with back-up ring.
In order to improve prior art further, the special feature of rotary location tool of the present invention is also: described central tube is provided with boss, and described boss is flexibly connected with described guide cylinder.
Rotary location tool of the present invention adopts on central tube and is provided with J type groove, and guide cylinder is provided with elongated slot, and cylindrical pin upper end is flexibly connected with elongated slot, and lower end is flexibly connected with J type groove.Because J type groove is length groove, when cylindrical pin moves up and down in elongated slot, make it in J type groove upwards or after moving downward a segment distance, drive guide cylinder to rotate motion relative to central tube.This rotation location can make the pack hole on filling crossover tool and the filling corresponding aperture on sliding sleeve locate very accurately, and deviation does not occur; Even if when stowing pressure is excessive, also can pressurize to service aid, thus prevent from service aid moves.Thus, the present invention has compared with prior art and can carry out multiple bearing in different positions, realizes amphicheirality location, safe and reliable, the advantages such as accurate positioning.
As can be seen here, compared with prior art, the present invention has outstanding substantive distinguishing features and significant technological progress, and its beneficial effect implemented also is apparent.
