SYSTEM FOR MONITORING THE BOTTOM PROFILE OF A BOREHOLE

WIPO Patent Application WO/2022/220706

A3

The invention relates to systems for monitoring borehole bottom angles for use in horizontal directional drilling (HDD) and is applicable in trenchless utility laying operations. Proposed is a system for monitoring the bottom profile of a borehole during enlargement stages in the construction of utilities by horizontal directional drilling, which comprises a computer and software installed thereon for processing data and plotting a borehole bottom profile, which is designed to enable a connection between the computer and a device for monitoring the bottom angles of a borehole. Said borehole bottom angle monitoring device consists of a housing in which are mounted accelerometers, an electronic circuit board with a processor, a device for recording and storing information, and a power source. The technical result is that of making it possible to determine and monitor the angles of the borehole trajectory after each enlargement in order to adjust the run-in geometry of the head of a pipe in the borehole, and to obtain and process live statistical data about the geometry of the borehole and to plot the bottom profile of the borehole.
