Problems solved by technology

[0005] However, there are still many difficulties in the exploration of engineering early warning at home and abroad: (1) The applicability of the model is insufficient
For example, foreign forecast models based on data from adjacent wells, when there is a large difference in the formation distribution between the drilling well and the adjacent wells, there will be false alarms and other phenomena in the early warning; some early warning models in China mostly use fixed and customized methods, and the applicability of the model is poor ; (2) The defect of the algorithm itself
Customized adjustment algorithms require a large amount of expert experience and data, and these experiences and data often have regional differences and cannot be shared in a timely and complete manner, making full use of information impossible

Abstract

The invention relates to an intelligent safety risk early warning method and system for drilling engineering. The method comprises the steps: obtaining adjacent well abnormal data of a to-be-drilled well through a preset knowledge base, and building an abnormal early warning model of the to-be-drilled well according to the adjacent well abnormal data; acquiring real-time data information of the to-be-drilled well in a drilling process; and performing early warning analysis on the real-time data information based on the abnormity early warning model, and sending an early warning analysis resultto a remote terminal. According to the method, the abnormal early warning model is established, early warning analysis is carried out based on the abnormal early warning model; tracking, forecastingand early warning can be carried out in time, the well site risk can be effectively avoided, the accident occurrence rate is reduced, efficient drilling and intelligent decision making are achieved, unattended operation of the well site is achieved, the intelligent degree is higher, and the working efficiency is obviously improved.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to an intelligent safety risk early warning method and system for drilling engineering. Background technique [0002] Petroleum drilling is a complicated underground project, and there are a lot of fuzzy, random and uncertain factors. Accidents may occur at any time during the drilling construction process, which seriously threatens the safety of drilling. According to the data, the annual drilling construction accident handling The time accounts for 6-8% of the total time, causing a huge waste of funds, but also accompanied by shocking environmental damage. [0003] How to predict the possible drilling abnormalities during the drilling process, and how to give timely alarm to the drilling abnormalities that occur are the difficult problems facing the oilfield enterprises. Traditional engineering early warning methods mainly rely on human factors, including the analysis conclusions...
