Abstract

The invention provides an intelligent drilling machine control system for a driller. The intelligent drilling machine control system for the driller comprises a well drilling parameter acquisition module, a well drilling rotating speed optimization control system, a well drilling bit pressure optimization control system, a well drilling top drive / rotary table electric drive control system and an automatic bit feeding alternate-current variable-frequency control system. The intelligent drilling machine control system has the beneficial effects that modeling is conducted on drill column movement, and the relevant factors such as the relation of the drill bit speed and friction torque and the rotary inertia of a rotary table are considered, so that downhole stick-slip and other complex vibration phenomena can be effectively inhibited; and in accordance with the requirements of a drilling technology, real-time well drilling data are acquired, the deviation of the given rotating speed and the output rotating speed and the deviation of the given bit pressure and the output bit pressure are subjected to self-optimization compensation, and the deviation is made to tend to zero, so that optimum control over the rotating speed and the bit pressure is conducted, the well drilling cost is lowered, and the well drilling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling, and in particular relates to an intelligent drilling rig control system. Background technique [0002] In recent years, due to the widespread operation of ultra-deep wells, extended-reach wells and horizontal wells, the difficulty of drilling exploration and development has continued to increase, and oil drilling exploration and development accidents have occurred frequently around the world; Oil and gas exploration and development are under tremendous pressure, which has seriously affected the healthy development of the industry and national energy security. Relying on innovative technologies, how to effectively reduce oil and gas exploration costs and improve drilling efficiency has become an industry consensus and a top priority. [0003] Drilling tools are affected by factors such as friction, pressure, and rock texture when cutting rock formations, and there are often phenomena s...
