This paper outlines a automated drilling system, and articulates the components and mechanisms of its sub system, namely the surface automatic control system, down hole automatic control system and drilling information system.
On the basis of analyzing deep well drilling technology aboard, such as:directional,horizonal,cluster well,underbalance,coiled tubing,coring,well control and automation drilling technology,presents situation of drilling equipment in SPA in this paper. And the main development issues of Sichuan drilling equipment in the period of the 9th five year plan are given esearch and application of drilling equipment of deep well,ultradeep well,underbalance,shallow gas reservoir.
Digitalized drilling system contains four information layer, i.e. surface equipment layer, drilling team operation layer,expert decision layer and oilfield manage layer, and five subsystens, i.e. drill engineering design & manage, drilling database & expert decision, drilling operation monitor & manage, electromechanical equipment & measure device and drilling information network. Many problems of the digitalized drilling system are published about the network, information resource and automatic rag to be researched.
