Application of Non－Stabilized Well Test in Analyzing Geological Model in Water－Drive Pools

： On the basis of analysis and study on the non－stabilized well testing data from more than 320 wells in Baikouquan oilfield， the paper summarized 12 major well－testing geological models and carried out in－depth analysis on the observed stabilized typical well－testing curve characteristics． The well testing analysis results play an important role in reconstructing the contaminated reservoirs， out－laying reservoirs， optimizing water－flooding， reservoir evaluation andperformance analysis and have achieved both significant economic benefit and social effect．
