摘要
Abstract
Q block of Kunbei oilfield with long section of pay zones is featured by low porosity and low permeability reservoirs ,which results in very complex interrelationship of permeability and porosity as well as complicate oil and water layer logging responds .Through multi-discipline study and integrated interpretation ,we analyzed the effects of fresh water mud on array induction and lateralog ,it is found that the former is much more suitable than the later in the case study reservoir .We also studied log facies of different rock types and identified logs sensitive to these various rock types .With weighted accumulation method ,an optimized model of pore structure classification with conventional logs is built .On this basis ,the workflow and related charts are built for hydrocarbon evaluation in the studied block . The method is also useful for similar reservoirs with low porosity and low permeability .关键词
