METHOD OF HYDRODYNAMIC INVESTIGATIONS OF HORIZONTAL WELLS IN REAL TIME Russian patent published in 2013 - IPC E21B47/00

Abstract RU 2483212 C1

FIELD: oil and gas industry.

SUBSTANCE: method involves excitation of a well, measurement of parameters by means of bottomhole instrument installed inside perforated tubing in horizontal sections of the well with different geophysical characteristics and processing of measurement results. As bottomhole equipment, remote instruments are used, which are connected to each other by means of a geophysical cable; geophysical cable is led out by means of an outlet adapter from the tubing string to the inter-tube space. In vertical part of the well there installed is a borehole pump, and a downhole pump equipment is lowered together with the lowered geophysical cable. At that, the geophysical cable is fixed on the tubing string with belts; the cable is led out to the surface through a process hole made in a tube holder, where it is sealed and connected to a surface recording unit.

EFFECT: possibility of obtaining operational information on properties of productivity of a horizontal shaft in real time during the well operation.
