Example Embodiment

[0013] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and provides detailed implementation methods and processes, but the protection scope of the present invention is not limited to the following implementations example.

[0014] As shown in FIG. 1 , this embodiment includes a signal acquisition and processing module, a process control module, a human-machine interface module and an action logic control module. The signal acquisition and processing module is responsible for information acquisition and processing. It uses sensors to collect distance, pressure and other signals in real time, and obtains digital signals through A / D (analog / digital) conversion, and then obtains the required information through digital filtering. This information is transmitted to the process control module, which converts th...

Abstract

The invention relates to a drill rod straight automatic detection and straightening integral controlling system, belonging to automatic control technical field. The inventive system comprises a signal collecting and processing module, a process control module, a man-machine interface module and an action logic control module, wherein the signal collecting and processing module obtains and processes information and transmits the processed information to the process control module, the process control module converts the information sent from the signal collecting and processing module into process control information to be sent to the action logic control module and the man-machine interface module, the man-machine interface module provides an interaction platform between operator and system, via which operator can adjust the process parameters of the process control module, the action logic control module controls the action of executors and uses the man-machine interface module to real-time display the action state of system or operate system action via the man-machine interface module. The invention serially connects checking and straightening to realize the accurate, reliable and effective automatic control on each sub system.

Description

technical field [0001] The invention relates to a system in the technical field of automatic control, in particular to an integrated control system applied to automatic detection and straightening of drill pipe straightness. Background technique [0002] Oil and gas well drill pipe is an important tool for oil and gas drilling and production. Seamless steel pipes for the petroleum industry - oil well pipes include drill string components (drill pipes, drill collars, etc.) and casings and oil pipes. Drilling pipes and drill collars must be used for drilling operations in oil exploration and development, casings must be used for cementing, and tubing must be used for oil production. In the process of oil and gas drilling, the drill pipe is subject to huge axial pressure and torque, and the drilling depth is required to reach several thousand meters, which puts forward high requirements on the straightness of the drill pipe. The drill pipe is a non-equal-diameter seamless ste...
