In this way, due to the deviation between the occurrence time and end time of the drilling accident marked manually and the real occurrence time and end time, the essential cause of the drilling accident cannot be accurately obtained in the later analysis, resulting in oil drilling accidents. The accident warning system cannot accurately predict the occurrence of oil drilling accidents in the subsequent drilling construction process
[0004]
In addition, in the existing early warning system for oil drilling accidents, only a small part of the process uses computers to analyze historical data, while most of the processes are completed by manual operations, which leads to the prediction efficiency and accuracy of the early warning system for oil drilling accidents. are lower

Embodiment Construction
[0028] Below, combined with Figure 1-3 The method for marking the oil drilling accident time of the present invention will be described in detail with specific verification examples.
[0029] like figure 1 As shown, the oil drilling accident time marking method of the present invention comprises the following steps:
[0030] First collect the historical data during the oil drilling construction process, and group the collected historical data according to the corresponding drilling well number JH. When collecting historical data, the collection time interval Δt is a constant value, and preferably, the value of Δt ranges from 1 s to 10 s. Then, according to the order of the collection time t, sort each set of historical data and the corresponding accident-related parameter value P in the collection time t, and record the data sequence number of each piece of data as i, and i=1, 2, 3ΛΛ, wherein, the accident-related parameter value P refers to the value of the relevant param...

The invention relates to the technical field of petroleum drilling, in particular to a method for marking occurrence and deadline of petroleum drilling accidents. In order to improve the prediction efficiency and prediction accuracy of petroleum drilling accidents, the invention provides a a method for marking occurrence and deadline of petroleum drilling accidents. The method comprises the following steps: acquiring historical data of petroleum drilling and grouping and sorting; performing primary smoothing processing on the historical data to obtain primary smooth data, and adding a difference item of two adjacent primary smooth data; extracting starting point data, end point data and accident data of an accident according to the change trend of the primary smooth data; according to thedata length of the accident data, carrying out primary smoothing or secondary smoothing on accident related parameter values, and storing a processing result; and determining final accident data, actual accident occurrence time and actual accident ending time according to the processing result. Actual accident occurrence time and actual accident ending time marked by the marking method are high inprecision, and prediction efficiency and accuracy of petroleum drilling accidents can be improved.
Description
technical field [0001] The invention relates to the technical field of oil drilling, in particular to a method for marking the occurrence and cut-off time of oil drilling accidents. Background technique [0002] Oil drilling is a high-risk and costly system engineering. During the drilling construction process, engineering accidents such as blowout, lost circulation, and drilling tool damage may occur at any time, and once an engineering accident occurs, it will lead to major losses of funds, time, and even life and property. [0003] In order to reduce or avoid the losses caused by engineering accidents in the process of oil drilling, people in the field have designed an early warning system for oil drilling accidents. time to predict. However, in the above historical data, the occurrence time and end time of the oil drilling accident are manually marked by drilling personnel after the drilling accident occurs. In this way, due to the deviation between the occurrence tim...
