Abstract:

In well drilling process,it is difficult to establish the intelligent early kick warning model based on sample information
due to the complexity of geological information or the lack of adjacent well data. Through researches on the mechanism
and characteristics of the kick occuring,we suggest an exploratory well drilling intelligent early kick warning method by using
drilling expert knowledge and hierarchical fuzzy expert system and develop corresponding software system. By fuzzifying
parameters of kick occurring and with calculation based on fuzzy inference rule,this model is able to provide fast andaccurate
early kick warning. Field test data reveals thatthe intelligent early kick warning results are good and have a good application
prospect.

Key words: well drilling, fuzzy expert system, hierarchical model, kick, intelligent early warning
