Abstract

The invention discloses an intelligent well drilling expert system. The intelligent well drilling expert system comprises an on-site sensor detection system, a communication system, an intelligent expert system and an operation system. The on-site sensor detection system is connected with the intelligent expert system through the communication system, the intelligent expert system is connected with the operation system, and thus the automatic closed loop well drilling adjusting and controlling system is formed. The on-site sensor detection system acquires data of the whole well drilling process. The acquired data are transmitted to the intelligent expert system through the communication system, so that processing monitoring, forecasting, analyzing, controlling and processing are conducted, and finally the operation system executes an operation instruction sent by the intelligent expert system after analyzing. The intelligent well drilling expert system can achieve real-time performance and the functions of early finding, early forecasting, explanation at any time and automatic control, and not only provides accurate information for well drilling engineering but also has the advantages of reducing well drilling cost, increasing well drilling speed, completely preventing accidents, and finding oil and gas accurately.

Description

technical field [0001] The invention belongs to the technical field of drilling exploration and development, and in particular relates to an intelligent drilling expert system. Background technique [0002] An oil drilling rig is composed of a lifting system, a rotating system, a circulation system, power equipment, auxiliary equipment, and a drilling rig base. It is a large and complex drilling factory that completes oil exploration and development tasks in accordance with drilling engineering and process requirements. The control system and monitoring and testing instruments are the core systems that reflect the technical level of oil drilling rigs. Since the drilling rig is mechanical, hydraulic, pneumatic control, electric control, and geology, chemistry, mathematics, geometry, material mechanics, fluid mechanics, etc. In the process of drilling rig production and matching, there are as many as dozens of manufacturers supporting the same set of drilling rigs. Due to prof...
