ACCESSORIES unpackaged CONCURRENT CHARGE FOR EXPOSURE TO OIL AND GAS gasdynamically and coalmine

摘要

The invention relates to the oil and gas industry. Attachments unpackaged sectioned charge for the gas-dynamic stimulation, comprises a flexible element 1, for example a cable, which are put in series before assembling pallet 2, the sleeve 3 and the lid 4. The lid 4 and tray 2 are in the form of truncated cones and are provided at the base-ring centralizers 5. The cover is rigidly connected to the logging cable 6 or the flexible tubing through the cable lug 7 on which is installed the charge coupler section 8, made in the form of a sleeve 9 of the rope 1 and the hook 10. The threaded bushings 3 outside hav e shaped thickening 11 which reduce the contact surface with the borehole wall. Sleeve 3 made of a resin such as polyurethane. 5-ring centralizers are made of rubber or polyurethane. The technical result - simplification of the design, its processability (using the same design of the pallet and lid) expansion of functionality, namely, allows processing not only vertical but inclined and horizontal wells, and wells diameter 110-127 mm. 1N. 3 ZP f-ly. 3 Fig.
