Abstract

The invention discloses a well drilling data processing method. The well drilling data processing method comprises the following steps of step 1, acquiring well drilling data of a target well at a current moment and a previous preset duration; step 2, determining whether a risk exists in the target well at the current moment or not according to the well drilling data by using a preset risk identification model, and if yes, executing step 3; and step 3, determining a risk prevention and control scheme of the target well by using a preset risk prevention and control model according to the determined risk type and the well drilling data of the target well at the current moment. According to the method, a big data analysis technology is used for mining and analyzing the data, the risk identification model, the risk prevention and control model and an efficient drilling model are researched and established, real-time analysis of the well drilling data of the target well is achieved throughintegrated application of the models, the well drilling risk can be identified and predicted timely and accurately, the risk is prevented and controlled, and meanwhile, on the basis of risk preventionand control, safe and efficient well drilling is achieved through real-time drilling optimization.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration and development, in particular to a drilling data processing method. Background technique [0002] With the deepening of exploration and development, the difficulty of oil and gas exploration and development is getting higher and higher. At present, the geological conditions faced by oil and gas exploration are becoming more and more complex, the buried depth of reservoirs is increasing, drilling engineering is facing more and more complex risk situations, and drilling problems are becoming more and more serious, which leads to more and more costs for dealing with drilling risks and accidents. higher. Especially in the exploration of exploratory wells, due to the unknown geological conditions, drilling risks frequently occur, and drilling costs remain high. [0003] Achieving safe and efficient drilling is the primary goal of the drilling industry. The identification and control...
