Research on the Water Production Tracking Method of Horizontal Well in Heavy Oil Reservoir with Bottom Water

Abstract At present, the model of heterogeneous fluid production in horizontal wells bottom water reservoirs does not comprehensively consider influence parameters such as flow, length, and position each section, resulting distortion interpretation results. Using Green function Newman product method, this paper derives heavy oil reservoir. The Stehfest numerical inversion algorithm was used to obtain pressure solution well reservoir with wellbore storage effect skin effect. By drawing typical chart test sections, new can be divided into five flow stages: stage, transition radial linear late stable stage. Based on conventional parameters, permeability, storage, effect, further diagnose liquid position, volume section. field application examples verify validity research results broad prospects.
