The invention relates to the oil industry and can be used in installations for the operation of wells, mainly with installations equipped with submersible pumps, for example, for well killing before they repair and drain of God the housing with two diametrically made channels, and the stop element [1]

Known valve does not provide a reliable opening of channels in the body.

The aim of the invention is to provide a reliable opening of the channels, as well as providing the possibility of multiple use of elements of the valve.

This is achieved by the fact that the downhole whipped valve comprising a housing with two diametrically made channels, and the stop element, the latter is in the form of a rod made of ductile metal, the ends of which are mounted in the channels of the body, and cut elastic sleeve tightly mounted on the rod, having a length less than the length of the rod, the ends of which are hermetically mounted in the bore made in the channels of the body.

In specific examples, preferably to produce a rod of copper. For convenience of Assembly of the valve and ensure the tightness of the valve is performed with the diameter of the rod, equal to the diameter of the channels in the housing, and the length of its ends mounted in the channels of the body, should not be less than its diameter. Part of the body, which carried out one of the channels is removable and is bound in the body, for example, using threads.

The drawing shows a well whipped valve.

The valve sustaita installed shut-off element, consisting of a rod 4 and the elastic sleeve 5. In the channels of the body has a bore 6 and 7. Part 8 of the case is made removable and is threaded. When assembling the valve, one end of the rod 4 with the end of the elastic sleeve 5 is mounted respectively in the channel 2 and the bore 6 in the removable part 8 of the housing 1. The removable part 8 of the housing 1 is screwed into the case, while the other end of the rod 4 and the elastic sleeve 5 are respectively the channel 3 and the bore 7, made in diametrically opposite to the channel 2 of the housing. The valve is installed in the well tubing. Through the lubricator in the tube is discharged cargo, for example, the length of the rod. The cargo against the rod 4 with the sleeve 5, prohibit them, the ends of the rod and sleeve out of the channels of the body, freeing them communicating sections, through which is carried out, for example, well killing fluids.

SUBSTANCE: there is a description of pipe string for well completion installed in position neighbouring to zone or zones where hydraulic fracturing (HF) is to be performed and inflow is to be obtained. In preferable version its peculiarity concludes in valves with sliding couplings allowing implementation of at least two configurations; wide opening and opening of channel with filtering material located in it. Valve unit may have three positions where a position of complete closing is added to two above mentioned positions. After run-in-hole operation valves may be set to position of wide opening in any order required for HF. After completion of HF valves may be either closed or set to filtering position in a differentiated way to get inflow from the zone subjected to HF in any required order. There are various methods for valves actuation described. Pipe string may be provided with telescopic forcers providing HF if it is required to do string cementing.

SUBSTANCE: fluid supply device features sensor of plugs (darts, balls, etc.) passing through tool. Actuator shifts tool insert after a preset number of plugs has passed through tool. Insert shift opens catcher in tool bushing. After next plug discharge, catcher connects to the plug in bushing so that fluid pressure applied to the plug installed in tubing string can move the bushing. Shifted bushing opens windows in tool, connecting tool channel to surrounding annular space, thus enabling treatment of formation interval adjoining well shaft to intensify flow. Actuator can use sensor of plugs passing through tool. Spring housed in tool can bend at approach to sensor when a plug passes tool, and sensor counts number of plug passes.

EFFECT: enhanced efficiency of multistage hydraulic fracture in one round trip operation.

SUBSTANCE: group of inventions is related to mining and may be used in a string or equipment for wells completion. The mechanical sliding sleeve (101) includes a guard (105) with openings for interconnection with fluid, the first adapter (103) connected to the sleeve guard and the second adapter (107) connected to the sleeve guard. An insulating bushing (201) is placed in the inner channel formed by the sleeve guard, the first adapter and the second adapter thus forming an opening (113) for interconnection with fluid. The insulating bushing slides along contact surfaces between the first adapter, the second adapter and the sleeve guard in between the open position when fluid comes through openings and the closed position when fluid passage is prevented through openings. The sealing element is coupled functionally to the sleeve guard, the first adapter, the second adapter and the insulating bushing in order to prevent fluid passage through openings when the sleeve is not in the open position and to insulate at least part of contact surfaces from contact with borehole fluids.

EFFECT: improving operational efficiency of the sliding sleeve.

SUBSTANCE: method involves landing of tubing string with packer to a well, packer seating, hydraulic fracture liquid injection by the tubing string with packer to a low-permeable formation, hydraulic fracturing of the low-permeability formation with further fracture fixation by injection of liquid carrier with propping agent via the tubing string, pressure relief in the well. Before tubing string landing to the well, water-bearing interlayer interval of the low-permeable formation is perforated to form perforation holes. Then at the wellhead the tubing string is filled upwards from the bottom with a plug, lower hole rows, packer, upper hole rows and additional packer. Inside the tubing string, a mobile bushing with radial channels is inserted to seal lower hole rows of the tubing string tightly in initial position and connecting the tubing string via upper hole rows and perforation holes to the ware-bearing interlayer. A seat is installed inside the mobile bushing, the mobile bushing and the seat are fixated in initial position against the tubing string by a differential shear element. The tubing string is landed to the well, packer and additional packer are seated in the well so as to shot water-bearing interlayer off tightly at two sides, upper water0bearing interlayer is isolated by injection and flushing of water isolation composition via the tubing string through upper hole rows to the water-bearing interlayer through perforation holes under pressure twice lower than hydraulic fracture pressure of the formation, process break is made for solidification of the water isolation composition, then a ball is dropped to the tubing string from wellhead, and overpressure is formed in the tubing string. First the shear element is destroyed, and under impact of overpressure above the ball, mobile bushing is shifted down along the tubing string to a stop against the tubing string plug, overpressure increase in the tubing string is continued, and the shear element is destroyed again. The seat is brought down to a stop against the plug under impact of overpressure above the ball. Upper hole rows of the tubing string are shut off tightly by the mobile bushing, and lower hole rows are connected to the tubing string by radial channels of the mobile bushing.
