A Comprehensive Multi-Factor Method for Identifying Overflow Fluid Type

Accurate identification of overflow fluid types facilitates timely and effective handling onsite accidents. Research into identifying the type is limited, there are only simple calculation models that do not consider enough effects; additionally, accuracy needs to be improved method perfect. If no drilling data, it impossible identify fluid. Therefore, this paper modifies density model by considering influence temperature, pressure field, two-phase flow model, making result more accurate universal, puts forward a comprehensive for auxiliary based on gas logging interpretation. This uses state equation verify model; after verification using data from than 20 overflowing wells, was found practical had an rate 90%. Thus, study proposed can provide guidance dealing with accidents in field any follow-up research.
