Control system and the monitoring Displaying Meter
Carry out work in order to command, control each unit cooperative ground, a whole set of rig is equipped with various control device, and have machinery controls, gas control system, electric control, hydraulic control system and electricity, gas, liquid commonly used mix control.Mechanical powered rig generally adopts centralized and unified gas control system.Modern drilling machine also is equipped with various drilling instruments and measurement-while-drilling system, and monitoring shows the working condition of the relevant system equipment in ground, measures downhole parameters, realizes hole trajectory control.
7. rig substructure
Base comprises drillingrig base and machine room base, is used for drilling equipment is installed, and facilitates the movement of drilling equipment.Drillingrig base is used for installing derrick, rotating disk, places pipe setback and necessary rig tool and driller's console, and majority is also wanted setting winch.Drillingrig base should be able to hold necessary wellhead assembly, therefore, enough height, area and rigidity must be arranged.The machine room base is mainly used in installing powerplant module and drive system equipment, therefore, also enough areas and rigidity will be arranged, and centering, smooth working and movement can be installed rapidly conveniently to guarantee calculator room equipment.
8. auxiliary equipment
Complete rig also must have air feed equipment, auxiliary generating plant, blowout preventer equipment, rat holing equipment and auxiliary hoisting equipment, also must be equipped with heat-preserving equipment when the cold zone drilling well.
The pattern of oil-well rig is various, can be divided into: drive pattern, driving type, movement mode.
Be divided into by driving pattern: Diesel Driven, electricity drive, hydraulic-driven.Wherein electricity drives and is divided into again: alternating current driving, dc powered, alternating-current variable frequency power drive.
Be divided into by driving type: chain drive, the transmission of V band, gear drive.
Be divided into by the movement mode: packaged formula, self-propelled, pulling type.
Over more than 40 year, process imitated, that introduce digestion, absorb that the China's oil rig has experienced has now entered take independent development as the main stage.Over nearly 10 years, the China's oil drilling rig technique obtains developing the most fast, and manufacturing capacity is greatly improved.The various rigs that China rig manufactory makes satisfy the needs of petroleum exploration in China development self substantially, successively developed the oil-well rig that is suitable for land, desert and ocean operation, drive technology has developed into machine driving, direct current transmission, AC frequency conversion electric transmission and mechanical, electrical Composite Transmission and has developed simultaneously.China has formed the ability of 200, year manufacturing rig, has become global maximum rig manufacturing nation.The China Petroleum that develops into of China's oil drilling rig technique and manufacturing capacity is implemented low cost strategy, and participation competition in the international market and assurance China's oil are had laid a good foundation safely.
The complete system that modern oil-well rig is comprised of as machine the multiplex (MUX).In the course of the work, according to the needs of drilling technology, each working machine, must be guaranteed by control system in sequence and regular movement for this reason.Sensitivity, accurate, a reliable and secure control system can make rig be in the optimal movement state, and obtain economic benefit preferably.
