Log Curve Variation Characteristics and Evaluation of Different Development Phases in Beibei Block of Lamadian Oilfield
摘要
Abstract
Studied are the reservoir characteristics and log curves changes in more than 30 years developments in Beibei block of Lamadian oilfield. Analyzed are the log data from 467 wells of Beibei block, and summarized are the log curves changes laws and courses of acoustic logging, SP logging, natural gamma-ray logging, density logging, resistivity logging and micro-electric logging. In different developing periods, acoustic time curves display 2 trends of down-to-up and down-to-up-to-down. Spontaneous potential curves present up-to-down trends along with baseline drift. Natural gamma-ray and density curves show decline trends. Resistivity curves show 3 trends of up-to-down-to-up, down-to-up and down-to-up-to-down. Micro-electric curves present 2 trends of down-to-up and up-to-down-to-up. These trends reflect corresponding changes of various reservoirs in oilfield developments. The changing trends of poroperm characteristics, degree of reserve recovery, watered status, oil saturation, wettability and displacement efficiency in the oilfield developments imply a good effect of polymer flooding.关键词
