device for drilling long horizontal wells

摘要

the utility model relates to the oil industry and is designed for drilling oil and gas wells with long horizontal endings.in particular, can be applied in the layout of the bottom бурильной column (кнбк).;purpose of utility model is to develop a device that will increase the techno economic performance of drillingby preventing прихвата бурильной column through an optimum loading on the chisel, i.e.the development of the bottom бурильной columns and enhanced functionalities, which allow drilling long horizontal sections of the borehole.and to eliminate the недохождение drilling tool to design the slaughter.;the technical result is the change of frictional force on the force of friction on slip due to the significantly reduced resistance to movement of the drilling tool.;the aim is achieved in that the device includes a cylindrical body with embedded rollers, part of which is the contact points.located at a certain distance from each other. embedded videos in contact with the walls of the borehole, rotate and move forward to the layout of the bottom бурильной column.rotation of the rollers is fixed through the flow промывочной liquid and the frictional force of the cylindrical casing.node management allows to record the spatial parameters of wells, drilling regime parameters (axial load, the промывочной fluid speed породоразрушающего ying струмента etc.p.).
