Application Research of Borehole Cleaning Evaluation System Based on Cuttings Weighing

Due to complex working conditions and cuttings migration mechanism other factors, bed is easy form in deviated well section extended reach horizontal section, too high cause a series of downhole accidents, such as bit mud bag, wall collapse, stuck drilling holding drilling. The borehole cleaning evaluation system based on weighing can collect the returned real time. combines real-time flow rate, theoretical volume, actual volume data evaluate situation provide guidance for field construction. At same time, optimization analysis module designed system. adopts combination comprehensive logging geological data, combining advantages logging, which realize time maximum extent. In this paper, studied corresponding engineering application examples are given. It has practical value monitoring evaluation, aging reducing non-productive
