CABLE FOR GEOPHYSICAL RESEARCH inclined and horizontal section of the well

摘要

The proposed cable to the study of inclined and horizontal wells sites relates to the field of geophysical research and for lowering and lifting geophysical instruments and appliances, their power supply rated voltage up to 600 V and the implementation of information communication between surface equipment and downhole tools at well logging.; The purpose of this utility model is to provide a logging cable for the study of inclined and horizontal sections of wells easy to manufacture and use, which also provides high flow horizontal well sections.; The proposed cable is structurally divided into three sections, which allows you to create the optimum design to perform its functions in each of the cable sections.; The core in the upper and middle part of the cable is formed by twisting the steel wires into a steel cable, on which a shell of a polymeric material. At the bottom of the core is made of fiberglass circuit element having a diameter equal to the diameter of the core and the upper middle portion of the intermediate shell. At the core by twisting imposed one or more insulated conductive wires. In the upper part of the cable with the conductors in the superimposed isolated by coils of steel wire with a diameter equal to the diameter of the insulation of the conductive core insulation. In the middle part of the cable part of the steel wires may be replaced with a lead wire for weighting. At the bottom of the steel wires are replaced by power fiberglass elements similar in diameter to the diameter of the wire insulation. On twisting armor layer applied in the opposite lay direction. Above armor superimposed outer sheath of polymeric material.
