FIELD: well surveying.
SUBSTANCE: invention belongs to the well surveying. For this purpose the submersible pumping systems, containing an electricity-driven submersible pump in the bore hole, is used. The passing of logging equipment is fulfilled within the inner electrical submersible pump passage up to the position below the inner passage way of the electrical submersible pump at the time of exploitation of such a pump inside the bore hole. According to the second scheme the logging equipment is shifted through the inner lengthwise passage and through the motor shaft of the electrical submersible pump system, located within the bore hole, up to the position beneath the inner lengthwise passage. The borehole fluid is extracted through the flow passage, not being a part of the inner lengthwise passage during the shift of the logging equipment along the inner lengthwise passage. Well logging system includes electrical submersible pump system, having the inner flow passage, going through the electrical submersible pump in order to receive the logging equipment system. The logging equipment system is fulfilled with the possibility of electrical submersible pump passing along the inner flow passage up to the position below the inner passage way of the electrical submersible pump. The electrical submersible pump contains a flow fluid passage, separated from the inner flow passage in such a way, that the inner flow passage do not receives the fluid flow.
EFFECT: enhancement of the well exploitation efficiency by means of well logging procedures beneath the well equipment point from inside the bore hole.
