CONTROL AND SIMULATION TECHNIQUE OF THE PROTECTION OF FORMATION FROM DAMAGE

On the protection of formation from damage,the most important measure is to prevent it before the damage occuring,and to decide the ideas of proventing and controlling formation form damage.By making the simulation and emulation researches,we studied the identification and diagnosis of formation damages with the methods of neural network,as well as developed the computer software system IEDPTFD(Identification,Evaluation,Diagnosis,Precaution,and Treatment of Formation Damage) for formation protection.It consists of five subsystems and their knowledge bases,a main control module,a knowledge acquisition module,an explanation module(interpretor) and a man-machine interview module.Indentification,evaluation,diagnosis,precaution and treatment of formation damages is a systematical engineering.A set of mating protection technologies of formation from damage has been established.Application of these technologies has abtained good economical and social benefitial results.
