Problems solved by technology

[0005] However, whether it is a vertical well, a deviated well, a horizontal well or an extended-reach well, the execution equipment is realized by the electronic control system controlling the drilling rig drawworks, rotary table, top drive, mud pump, and solid control throttling well control equipment. In actual construction, the same wellbore structure, due to the difference in the personal experience of the drillers, and the fact that the various professions and technologies are basically out of touch in practical applications, will lead to the phenomenon that different drillers will operate with different effects occur

Embodiment Construction

[0121] The present invention is described in detail below in conjunction with accompanying drawing:

[0122] Such as figure 1 As shown, the present invention provides an intelligent drilling expert system, which enables the development and progress of drilling technology in the direction of informatization, intelligence, and remote automation. Under the pressure of the low oil price market, drilling risks are controlled, drilling parameters are optimized, drilling costs are reduced, and drilling efficiency is improved. It is an upgrading technology for oil drilling equipment and fills a gap in the industry. It has greatly enhanced the market competitiveness of oil drilling companies, and also contributed to my country's oil exploration and development and energy security.

[0123] Specifically, it includes: a field sensor detection system, an intelligent expert system and an actuator; the output of the field sensor detection system is connected to the input of the intelligent...

Abstract

The invention provides an intelligent drilling expert system. The intelligent drilling expert system comprises a field sensor detection system, an intelligent expert system and an execution mechanism. An automatic closed-loop drilling regulation and control system is formed. Data in a whole drilling process are acquired through a field sensor; then, the acquired data are transmitted into a computer for processing, monitoring, prediction, analysis, explanation, control and the like. Most importantly, through the researched cross-specialty and cross-industry intelligent expert control models for drilling hydraulic control, well wall stability control, friction resistance and torque control, drilling speed and cost control, drilling complexity and accident control and the like, instantaneity, early discovery, early prediction, interpretation while drilling and an automatic control function can be realized, and accurate information is provided for drilling engineering; moreover, the intelligent drilling expert system has the advantages of reducing the drilling cost, increasing the drilling speed, avoiding sudden accidents and discovering oil and gas accurately.

Description

technical field [0001] The invention belongs to the technical field of petroleum 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. [0003] 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 drillin...
