A Feasibility Analysis on Automated Drilling Technique in the Daqing Oilfield

The automated drilling has such benefits as optimizing drilling course, automatic control, drilling with high-quality high-efficiently, the high quality well bore, controlling well trajectory accurately, high success rate to drill deep well, ultra deep well, prospect well, complicated well, low costs, high efficiency drilling and economy advantage, etc. 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. Combined with the current drilling techniques, several automated drilling proposals are established. On the basis of a feasibility analysis, a conclusion that the automated drilling technique can be implemented in the Daqing Oilfield is drawn, this paper also put forward a suggestion that speed up researching automated drilling system self to improve domestic drilling technologies and shorten the gap with international ones.
