Description

The invention of ogiosigs to mining, namely, to the development or raising of a pool of wells drilled.

Yavosgny ycipoftcraa for lifting pulyay1 containing pipe and pipe for supplying the working environment.

The circuit of the invention is an increase in the efficiency of pulp removal and the use of the entire pipe section area.

The goal is to achieve that the device is made with the upper to the lower row of channels circumferentially, the lower row channels are tangentially directed, and the upper row radially at an angle of 6О-7О to the plane of the normal section of the pipe.

FIG. 1 shows a general view of the device for raising the pulp; in fig. 2 - section of the drill string tru6 | in fig. 3 - section A-A of FIG. 2; in fig. 4 - section BB of FIG. 2; on fng. 5 general view k & moles quicken upars; in fig. 6 - section of the lower end of the drill pipe string.

A device for lifting pulp socializes chisel. 1 with suction inlet

2, the drill string 3, which is laid on the blister pipes 4 and the leading drill pipes 5, fastened together by means of locking joints 6. jet pump 7, built into the drill string 3, and a hydraulic shock damping chamber 8, integral with the swivel and connected to the drain hose 9. The drill string 3 is passed through the rotor 1O of the drilling rig. The jet pump 7 is a mixing chamber 11 with an end to a regularly located air collector 12, connected by a spiral pipe 13 with a collector 14 of the hot water chamber 6, in turn, with a pipe 16 that is similar to the cooling pipe 15.

Collector 12 communicates with the internal cavity of the mixing chamber 11 with openings 17 and 18 that are evenly spaced around the circle in two directions, with the axis of the holes in the lower sapyca projected in the plan along the chords of the inner circumference at an angle of 30 to the corresponding axis; pa / gtycy image - at the intersection of the cavity, otrankchennuyu great VIP polychromat. flpooKHHH same BopxHGigo axes are ogrescent in terms of radialio On the axis of the vertical axis of camera 11, all of the angles are also inclined SBefjx at an angle to the plane of the normal. one plane 19, the Hypowder Quench Suppressor 8 contains natpy6KH 20 s in the ear canals 2ie communicating with the collector 14. Fpaniye 22 branch pipe 2O fastened to the NTC & Silent driving drill. t} shank 5, and cement 23 through the bearing unit 24 soy. Line with chamber 25 of the upper wall 5 of the wall 26 of which is provided with a suspension 27 with a hole 28 for communicating with the rigging system of the drilling rig. On both sides of the cover there are installed rollers 29 for quality NO0 along the drilling guides To the cover 26s with the opening 30, the screws 31 are attached the cylinder 32 is divided into two halves by a disk 33. A conical divider 34 is bore to the portions of the disk 33. The upper part of the cylinders 32 has an inner cylinder 35, moreover, in the outer wall of the cylinder above the disk 33a in the inner wall of the cylinder 35. The holes 36 are arranged in staggered order relative to each other. At the top of the cylinder on the disk 33, the float 37 is loosely shaped as a wooden disk. Metsdu cylinders 32. and the chamber 38 left an annular gap 39 In the bottom 4Q of the chamber 8 there is a drain connection 41 connected; With a hose of 9 slurry pulp, For operation at a depth of more than 1OO m, the device is equipped with a pipe 42 with rows of inclined angles 6O of holes 43 located tangentially in the two lower rows and radially - in the rest of the pulp lifter operates in the same way. With the surface of the day, the mouth of the stubble is drilled with a chisel 1, which receives rotation from the potxspa 10 rig, through which the drillstring 3 is passed, after the destruction of the separating well from the orientalnik, water flows mixing up with From the compressor 15 through the pipe 16, the collector 14j, the channels 215, the airflow systems 13 and 13, the openings 17 and 18 enter the cavity ™ of measure 11 and enter the cavity. air. Oduh stream, I (| iosgupa with a large speed (about 2OO m / sak) in polosposp :)). Mixing chamber with g., Yari, due to the fact that the air is flowing through the bottom 17 of Heix) rus tangentially and obliquely towards The axes of the chambers inside it form a void wall of a 5-hole hollow column of aerated pulp that penetrates the 18 holes of the 18 BepxHeix and pierces through the radially directed inclined air jets immediately mixed with the pulp. Bone 19 podnimayuschiys up nopodobne. The natural tornado conditions of which are simulated in the mixing chamber 11 The stream of aerated pulp along the string 3 enters the hydraulically hydraulically controlled 8s chamber where the impact of the conical divider 34 changes the direction of the air that through the annular aasof: MILK 38 and holes 36 and ZO, tert sn & rj, YOU go out, pours freely into the sump through the pipe 41 and the waste hose 9, Yoop pumping capacity exceeds the capacity of the drainage pipe, excess pulp penetrates through the annular gap 3.9 and oTBapCTJ-tE 36 in top it is the cavity of the cylinder 32, raises the depths of the shops 37j which n "ekryvavvg holes AOR. As a result, the path is filled with bridging air under the pressure of the colivaur through the nozzle. Upon reaching a depth of 5 m, column 3 rises with a second hanging drill pipe upwards from the pump 7, which maintains its position above the chisel i. In the future, the drill string is increased "due to the bumping pipes installed between bit 1 to the pump 7 and fastening" with the help of the lock joints of 6 meters. The need for the next pump depth occurs when the well reaches the slab 4O-5O m. Above the pump 7, another leading drill pipe is installed, onycTHs it is also depth-& -12.M9 gradually increasing the column down from the kaoos, leading to a depth of 1 sec. By further lowering the isacxjca by increasing the leading drill string up from the mixing column cameras 11 pr There is a limited output of the oil well cell. Therefore, for drilling to a depth of more than 1OO m, a tube 42 is inserted into the inside of the drill string 3, the upper end of which is connected to the collector 12, B through the slit of the column 3, the slurry of the SL and the small specific gravity of the bottom upwards, 42 increases in the deepening of the well. The working medium for the jet pump can also be segmented with water. At the same time, the centrifugal pump can be used as a source of pressure for the serpentine compressor. 62 2 "826 Formula of a genre A device for lifting a pulp containing a pipe and a pipe for a primer of the working medium is characterized in that, since the center of its efficiency in the NOS6 of the pulp and used in the entire area of the pipe sections, it is made from the upper and the sleeping quarters channels along the circumference, with the channels of the lower row directed tandekdialno, and the upper row radially at an angle OO-7O to the plane of the normal pipe sechenk.
