Problems solved by technology

The traditional drilling mode generally only has one or two modes. When the two modes are used at the same time, the status of the two parameters is the same, so there are great limitations in use, and it may seriously deviate from other parameters. The value required by the operating conditions, causing unnecessary damage and low efficiency

Abstract

The invention belongs to the technical field of petroleum drilling machine electric control systems, and particularly relates to a petroleum drilling machine multi-mode automatic drilling control method. The work condition modes of the control method include the single mode or the master-slave mode with one mode as the master mode and the others as the slave mode. The single mode is one of the three drilling modes of constant speed, constant drilling pressure and constant vertical pipe pressure. The master-slave mode is characterized in that one of the three drilling modes of constant speed, constant drilling pressure and constant vertical pipe pressure is selected as the aa master mode, and others are selected as the slave mode. Under the work condition of the master-slave mode, the master-slave relation is distributed automatically, or the master-slave relation can be changed at any time according to the habit and the special requirements, the master mode plays a leading role in the drilling process, and the slave modes play an auxiliary and protection role in the drilling process. By means of the method, the automatic drilling function is wide in use, accurate, safe and reliable and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of electric control systems for oil drilling rigs, and in particular relates to a multi-mode automatic drilling control method for oil drilling rigs. Background technique [0002] Since entering the 21st century, the level of automation, digitalization, intelligence and informatization of oil drilling rigs has developed rapidly. [0003] The automatic drill feeding of the oil drilling rig greatly reduces the labor intensity of the operator and improves the accuracy of drill feeding. The traditional drilling mode generally only has one or two modes. When the two modes are used at the same time, the status of the two parameters is the same, so there are great limitations in use, and it may seriously deviate from other parameters. The values ​​required by the operating conditions cause unnecessary damage and are less efficient. [0004] The multi-mode automatic drill feeding control method of ...
