Abstract

The invention discloses a control system for top-drive drilling equipment. The control system comprises a remote controller, a driller room controller, a top-drive controller, three first-level buses and three second-level buses, wherein every two controllers are connected with each other by thone corresponding first-level bus and one corresponding second-level bus at the same time, and a loop is formed by connecting the three controllers. Compared with the prior art, the control system can still normally work while part of a circuit has a faltilure, thus reducing the influence of the circuit fault to normal work and improving the production efficiency of the top-drive drilling equipment.

Description

technical field [0001] The present invention relates to oil exploitation technology, in particular to a top drive drilling equipment and its control system. Background technique [0002] Top drive drilling equipment is a kind of drill string that can be directly rotated from the upper part of the derrick space, and sent down along the special guide rail in the derrick to complete the rotary drilling of the drill string, circulation of drilling fluid, single root connection, make-up and breakout and back marking Drilling machinery and equipment for various drilling operations such as drilling holes. [0003] In order to control the top drive drilling equipment to work, such as figure 1 As shown, an electric control room and a hydraulic source are set on the ground, a remote controller is set in the electric control room, a driller’s room controller is set in the driller’s room at the base of the derrick, and a controller is set on the top drive body on the derrick There is ...
