Problems solved by technology

[0003] At present, when blowout warning is carried out in the oil field, the judgment of the blowout accident is often completed by the judgment of the on-site drilling experts on the monitoring data. It relies heavily on expert experience, and the effectiveness of blowout accident judgment needs to be further improved, lacking in timeliness, comprehensiveness and transferability

Abstract

The invention relates to an intelligent early warning method and system for blowout, equipment and a storage medium. The method comprises the following steps: acquiring the complete original oil and gas drilling process data; constructing a blowout early warning model based on a neural network; preprocessing the obtained complete original oil and gas drilling process data to obtain a training data set, and training the constructed blowout early warning model based on the neural network by adopting the training data set; testing and verifying the well-trained blowout early warning model in a real scene, and putting the blowout early warning model meeting the field application standard into application of a drilling field, so intelligent early warning of blowout is realized. The method can be widely applied to the fields of offshore oil and gas development and big data application.

Description

technical field [0001] The invention relates to a neural network-based intelligent blowout early warning method, system, equipment and storage medium, belonging to the field of offshore oil and gas development and big data applications. Background technique [0002] Limited by the complex geological environment and drilling technology during deepwater drilling, drilling accidents such as overflow, lost circulation, and blowout may occur. Once a drilling accident occurs, it may cause huge property losses, or cause casualties and bottom pollution. In order to reduce the risk of the drilling process and ensure the safety of drilling and staff as much as possible, researchers continue to explore technologies that can provide early warning of drilling accidents such as blowouts. [0003] At present, when blowout warning is carried out in the oil field, the judgment of the blowout accident is often completed by the judgment of the on-site drilling experts on the monitoring data. ...
