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