Description

The invention relates to means for delivering isoschionic materials into the well, namely, to deliver materials to the zones of complications.

Commonly used TPJH injection bam of shut-in materials for water to block three-sided and pore formation, install cement bridges, etc. It involves a large number of technical means, a large consumption of plugging and other materials, and it does not always provide the required quality of work due to the effect of drilling mud on the material delivered to a certain interval of the well.

A known container for the delivery of insulating materials into wells, made in the form of water-soluble capsules, polymeric shells, etc. ij.

A disadvantage of the known device was that the delivery of materials in capsules and shells is applicable only in relatively shallow vertical wells. In deep wells (1000 m and 6ojiee) such delivery is unacceptable for reasons of wall roughness, changes in the azimuth and angle Haj; bosom. Capsules and membranes can be broken or constricted in the well in the direction of change of the borehole when descending into the well. In addition, drilling fluids can be treated with various chemical reagents that affect the material of the capsules and shells in different ways, accelerating or slowing its destruction.

Closest to the present invention, there is a container for delivering insulating materials to wells, running down a cable and including a body filled with insulating material and made with removable upper and lower end plugs and a blast chamber in the form of a socket with end plugs 2.

A disadvantage of the known device is that it is not reliable in operation in the case of the use of sutsix isolation armatures due to their condensation under the action of air from an explosion.

The purpose of the invention is to increase the reliability of the delivery of dry materials by preventing them from being over-compacted during unloading.

The goal is achieved by the fact that the shipping container is insulating

materials into the well, run-down on the cable and including the body filled with insulating material and Bboioftnny with removable upper and lower end caps and explosive chamber. In the form of a pipe with end caps, it is equipped with upper one in the lower rods rigidly interconnecting the corresponding end caps of the body and an explosion chamber, the latter being placed inside an insulating material 5 and its plugs are removable, and the controller housing is made in the form of two articulated half-cylinders.

FIG. 1 shows / the container in the transport position, the general view in FIG. 2 - the same, 1 view from above;

The device includes a cylindrical body 1, closed at the ends of the verts} & 2 in the bottom with 3 plugs., Inside the case there is an explosive chamber 4, for example, of a cylindrical shape in the form of a socket. Camera 4 has a top 5 and bottom 6 plugs. The plugs 5 and 6 hold the chamber case with spring locks, 7. The explosion chamber serves to place an electrode of a toner, for example, a type of ED (on nr.l Rum is shown) and, if necessary, a local detonation of explosive charge. From the electric detonator) wire 8 wires, which were pulled through hole 9 in the chamber plug 5 and hole 10 in the housing cover 2. The wires are connected to the conductors of the container transporting cable. The container is equipped with the upper 11 and 12 rods, which are rigidly fixed with the ends of the upper 5 and in the lower 6 plugs of the nozzle of the suction chamber. The outer ends of the rods 11 and 12 are reinforced in the upper 2 and lower 3 caps of the housing. On the inner wall of the housing 1, guides 13 and 14 are strengthened, iuToioa passes through the holes in the coachers. The brackets are at the same time the stops of the shock-absorbing springs 15 and 16, the coils are seated on the rods and fastened in brackets with external ends. The spring locks 7 are also connected to the straps 13 and 14, for example, by means of cables 17.

The upper plug 2 (Fig. 2) is made with opposing peripheral notches 18 in which the hinges 19 that are fastened to the case are placed. The loops are T-shaped and converge with their upper shelves on the container axis. Through the matching holes in the loops, an eye 2 is passed, serving to hang the container on the cable. The container body 1 is made detachable on the side surface, for example, of two half-lindres, connected by hinge connections (loops) 21. When the top 2 and bottom 3 plugs are removed from the ends of the body, its half-cylinders can unfold in loops x 21, and the hinges 18 are able to rotate on the eye 2 O. One of the half-cubic lids of the container body has a hatch with a lid 22 for installing the electric detonator uzo blast chamber and dozgrueki in the container of bulk materials. The container case and caps are expediently made of light-alloy or W1NX light, but sufficiently strong materials. The outer diameter of the container ensures its free transportation through the trunk and the cutting of the semicylinders, which allows its quick emptying. The length of the container can reach 10–15 m (which is limited by its manufacturing technology). The device operates as follows. The interval of the absorption zone in the well is determined, and then the container is started to be filled. The container may be filled with dry cement mixtures, dry cement, or other chemical agents to affect the formation. If necessary, the proposed container can be transported and shuttered cement or clay mixtures. The container is loaded with 2.3 n open body caps removed, the semi-cylinders are opened, and the half-cylinders are brought down to be loaded through the open ends, and after the plugs are seated on them, through the hatch 2, before the container is filled, insert an electric detonator into the explosion chamber 4 and insert with its plugs 5 and 6, between the spring locks 7, the hatch 22 is closed, the container is lowered into the well using a carriage hoist or a special winch on a wireline or other cable. having insulated conductors for blasting a detonator. When the container has reached a predetermined interval, the electric detonator is applied. The top 5 and bottom 6 plugs of the blast chamber move up and down respectively, the rods 11 and 12 fastened in them push the plugs 2 and 3 from the container body. Wherein . spring locks 7 jump off the casing of the chamber 4 and hang on the cords 17. After releasing the casing 1 from the caps of the container flap, they open the door as far as the diameter of the barrel allows. The container is emptied into the absorption zone, accelerated by the effects of explosives. gases and material pushing up and down plugs of the explosion chamber. All parts of the container hang on the cable. The cable is lifted from the treatment container and then it can be equipped for a re-voyage. Depending on the extent of absorption, a different number of flights may be required. Compared to the scaffolds, Cement slurry offered by Eontbyner has a number of technical advantages: a high productivity, since more cement or other cement mixtures can be shut off and used for one increased amount of insulating materials. Abot as n yusredstvenno is effected in an absorption zone; increased reliability of delivery of dry materials and the efficiency of their use. This shortens the time taken to eliminate complications. The economic effect of the invention is achieved by accelerating the work on eliminating the absorption zones, eliminating ground work on mixing cement materials (cement, clay, other chemical reagents), reducing the amount of materials used and, accordingly, the means for transporting them to drilling.
