Driver of horizontal oil well detecting instruments

A pipeline driver to draw the detecting equipments for the horizontal oil well was designed and man ufactured. This driver can work in the narrow pipes, high temperature and high pressure pipes, and can complete the continuous well logging tasks for the horizontal oil well. It improves the working efficiency, avoids the complicated assistant establishments, decreases the labor strength and reduces the cost of well logging. The static force analysis of the driver is given and its characters of high drawing force, long working distance and strict working security are shown. Simulation experiments of the single-prototype prove that the drawing force of this driver fulfils the requirments of design.
