Trade Lead Description:
LHE 4000 self-floating electronic single shot survey instrument is mainly applied to measure the well which has small inclination in the oilfield. Compared with suspending survey and dropping survey, there is no need to put away the kelly bar and use the winch. Besides, there is no need to adjust the mud circularly before surveying, which simplify the process of the survey, save the time, prevent the drilling accidents effectively, and improve the speed of surveying. The basic principle of work is: The survey instrument is sent to the bottom of the well to survey by the pump pressure. After completing the survey, the survey instrument will float off to the wellhead depending on its own buoyancy.
