| 英文摘要 |
| Kick has a significant influence on the oilfield exploration process, many drilling platforms adopt manual onthe-
job detection, which depends heavily on the accumulated experience of on-the-job personnel, resulting in false alarm
rate and high cost. Therefore, it is urgent to improve the efficiency and quality of kick detection. According to the findings,
including the deep learning technology into the drilling process can significantly increase the accuracy of kick detection.
However, because the frequency of kick is low, there are variances between wells and the available training samples are
restricted, the present kick detection algorithm’s applicability is limited. To address the aforementioned issues, this paper
proposes an adaptive long short-term memory (LSTM) kick detection algorithm that uses the sliding window method to
expand the data set, calculates the average increment, and realizes adaptive feature extraction of different well data, thereby
shielding the differences of different wells and improving the algorithm’s universality. The model performs well in off-line
verification and early detection of on-site kick, and it maintains high consistency with the expert’s experience annotation,
which is earlier than the operator’s log. The proposed method reduces the burden of on-the-job people with better efficiency
and quality, which is beneficial to improve the level of kick detection in drilling engineering |
