Abstract

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