Research and Application of Cuttings Flow Prediction Model for Horizontal Well

In the process of horizontal well drilling and logging, real-time continuous monitoring returned cuttings is needed to monitor cleanliness hole reduce complex accidents, such as bit mud bag, wall collapse, stuck drilling, leakage, which may affect construction logging operations. However, when metering device fails or acquisition data packet lost, can be incomplete discontinuous, poses a challenge for cleaning monitoring. order solve problem discontinuous caused by instrument failure collection loss weighing in operation, this paper studies compares three flow measurement prediction models abnormal loss. It provides reliable means reducing nonproductive time, evaluating borehole cleaning.
