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 cable for the study of inclined and horizontal sections of wells convenient to operate with a constant diameter along the length, which provides high flow horizontal well sections.; To achieve this goal the cable 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 parts is formed by twisting around a central steel insulated wire insulated conductive wires and steel wires isolated. At the bottom of the core is performed twist around the power element fiberglass insulated conductive wires and power fiberglass elements. Superimposed on the core intermediate shell of polymer material.; The intermediate shell on top of the two helix cable superimposed armor of galvanized steel wires in the middle of the first coils of superimposed discharged (number of wires is smaller than at the top). In the middle portion to increase the weight applied lead, filling them a free space between the wires of the first helix. The bottom portion of the wire is replaced by fiberglass strength member close in diameter to the diameter of second helix armor wires. Above armor superimposed outer sheath of polymeric material.
