A device for geophysical and hydrodynamic studies of the performance of horizontal wells

摘要

Complex for geophysical and hydrodynamic studies production horizontal wells in an assembly, the lowering of the tubing 1 connected couplings 2 includes logging cable 3, propeller 4, bracket 5 propulsor apparatus for geophysical cable extension 6, the electrical connection device 7 is connected to the geophysical 8 device.;Installed between geophysical instrument 8 and extension pipe 6 of the device the electrical connection comprises a circulation valve 7, 9 for pumping the cable contact tip 10 supported on the logging cable 3 borehole fluid.;Between the fixing device 5 and the upper mover clutch 11 mover 4 installed Pipe tension fuse 12 containing in its composition protecting member 13 and the sleeve 14. The emergency eject bottom of tubing 1 is mounted emergency extraction funnel 15.;The technical result - an increase of reliability of the device when performing geophysical studies and work in horizontal wells with excessive wellhead pressure, as well as extending the functionality of - extracting from the wellbore logging cable, apparatus and pipes in case of emergency. 1 yl.
