Annotation:
The "Recognition of Well Drilling Operations (RWDO)" software is designed to recognize well drilling operations based on the data from digital sensors of a geological-technological research station, their processing and visualization. RWDO is adapted to work with accumulated data. The RWDO network schedule helps to coordinate operations in real time. The algorithm can recognize more than 20 operations: drilling with a rotary and a downhole motor, drilling in a slide, rigging (cement bridge, shoe), extension of a drilling tool (DT), orientation of the BHA, lowering and lifting of a drilling tool in a cased and open hole, borehole drifting and drilling, build-up during tripping, stationary state of the DT in the well, measurement of curvature parameters from the downhole telemetry system (DHTS), flushing with rotation and without rotation of the DT, reaching the optimal drilling mode, lowering and lifting of the casing string, cementing.
