摘要： The device is used in technical operations during well completion. The device acts as a sealing device by using a seal (5). The seal (5) divides the well into an upper cavity (16) and a lower cavity (17). The seal (5) includes a collet (7) that comprises segments (8), a liner (10), springs (11) and a casing (6). The segments (8) are capable of separating upon interaction with the well equipment (drilling column (19)) and are provided with additional seals (9). The casing (6) is situated in the lower portion of the collet (7) and enables the movement of the segments (8) upon the separation thereof. The seal (5) is situated in a threaded (2, 3) housing (1). The housing (1) is secured in a roller bearing (4). The device further includes an adjustment insert (12) that is capable of interacting with the well equipment upon the installation thereof and of moving the same so as to open the channel of a hydraulic connection (13) between the well opening, the upper cavity, the lower cavity and the producing formation. This technical solution makes it possible to carry out any well completion operation, prevent the inflow of formation fluids and increase the yield of the well, well completion being carried out without the generation of overbalance on the formation. 3 dependent claims, 7 figures.

摘要： The device is to be used in the drilling and operating of various wells, and also in the construction and operation of surface pipeline systems. The device comprises a body 1, a stop valve 2, a potential energy accumulator 3 and a holding-lowering mechanism 5. The accumulator 3 is in the form of a spring, and the mechanism 5 is immovably fixed in the body 1 and is equipped with fixing elements 6. The valve 2 comprises a seat 7 and a disc 14 in the form of a drum. The outer surface 17 of the disc 14 has a conical groove 18 for the fixing elements 6. A lubricant-filled cavity 25 for the mechanism 5 is formed between the body 1 and surface 17, filled with a lubricant. On the inside the disc 14 has a through passage for a flow 19 with a surface of conical shape 22, which expands from the inlet 20 to the outlet 21, and with a surface of cylindrical shape 23 at the outlet 21. The disc 14 comprises a replaceable connecting piece 24, installed in the passage 19, on the inlet 20. The seat 7 comprises circulation passages 9 on an annular part 8 and has a boss 10, which is formed by a cylindrical surface 11 and by a spherical surface 12 with a spherical end 13. The technical solution provides maximum normative intensity of flow pass-through, controls closing and opening of the cut-off device, improves reliability of the cut-off device for safe operation and widens its applicability. 2 subclaims, 1 illustration.

摘要： The method pertains to the oil and gas industry and can be used in the development of producing formations. A producing string (6) together with a sealing device (7) are lowered into a well (1) and the well (1) is divided into an upper cavity (8) and a lower cavity (9) with the aid of said sealing device (7) to establish a hydraulic connection between the well opening and the upper cavity and between the lower cavity and the producing formation, respectively. The installation of equipment (10) and a check valve is carried out stepwise. A washer fluid (4) is replaced by a washer fluid (15). The equipment (10) is passed through the sealing device (7) and the hydraulic connection between the well opening, the lower cavity and the producing formation is re-established along the annular channel. The well (1) is deepened using the equipment (10) until an inflow of formation fluids occurs, the differential pressure in the hydraulic system "well opening - producing formation" being adjusted using the check valve and a blowout preventer (3). The equipment (10) is withdrawn from the lower cavity (9) upon completion of deepening, the device (7) is closed during separation of the cavity (9) from the cavity (8) and cutting-off the hydraulic connection between the producing formation and the upper cavity. The technical solution increases the efficiency and quality of technical operations and prevents the undesired inflow of formation fluids. 4 figures.
