基于钻井液侵入特征的阵列感应测井响应校正
CORRECTION OF THE ARRAY INDUCTION LOGGING RESPONSES BASED ON THE MUD INVASION CHARACTERISTICS
摘要
Abstract
Influenced by the brine drilling liquid invasion,the electrical resistivity logging responses are prone to deviate from the true resistivities of the formations.In order to accurately realize the invasion correction of the responses of the array induction logging,based on the water-oil two-phase flowing theory and litho-electric theory,according to the classifications of the formation porosity-permeability ratio (~/K) scope,with the help of the numerical simulating method,the invasion dynamic evolution process of the brine drilling liquid and its effects on the array induction logging responses were acquired under the different physical properties.The invasion simulation results show that the invaded profile characteristics are mainly influenced by the reservoir property and the invasion time,simultaneously,the invasion time and invasion depth are the key controlling factors on the array induction logging responses.According to dynamic invasion rules and considering the pressure difference,~/K and invasion time and so forth,the correcting method of the time-lapse resistivity simulation was established.The actual corrected results of the array induction logging show that the calculated water saturation values by the resistivity from the correcting method are in consistent with those by the sealed coring well measurement values,so the feasibility and accuracy of this correcting method are verified.关键词
