COMPLEX FOR GEOPHYSICAL AND HYDRODYNAMIC RESEARCH OPERATIONAL HORIZONTAL WELLS

摘要

The invention is made in the form of an assembly lowered along lift pipes 1 connected by sleeves 2, including a geophysical cable 3, a propulsor 4, a fastener attachment device 5 to a geophysical cable, an extension cord 6, an electrical communication device 7 connected to a geophysical device 8. 5 and the upper coupling 9 of the propeller 4 are installed a pipe strain relief 10, containing in its composition a safety element 11 and an emergency removal sleeve 12. At the bottom of the elevator pipes 1 an emergency funnel is installed This extraction 13. The destructible calibrated safety element 11 is structurally designed so that when axial forces are reached, the values of which are 20-25 kN less than the breaking load of the applied geophysical cable 3, it is destroyed. The emergency extraction coupling 12 has a cross-section, the edge diameter of which exceeds the internal section of the emergency extraction funnel 13. The tubular part of the electrical communication device 7 contains a circulation valve 18 to allow the borehole cable 19 to be pumped with a geophysical cable 3. Technical result: expansion of functional cable opportunities by eliminating emergency situations with pipes, instrument and cable and extraction of the elements of the device - geophysical cable , Device and pipes in case of emergency.
