摘要 涪陵页岩气田已经过10余年的商业开发,其岩石性质特征复杂,随着勘探目标走向深层,储层含气性评价受到制约。基于气田深层上奥陶系五峰-下志留系龙马溪组地质特征,开展含气性关键参数专项实验,建立深层页岩孔隙度、含水饱和度、吸附气等解释模型,并综合现场产能结果形成深层页岩品质及含气性综合评价标准,形成的含气性测井评价方法在涪陵页岩气田及周缘区块得到广泛应用。 The Fuling Shale Gas Field has been under commercial development for over a decade.As exploration targets move deeper,the complexity of rock properties imposes constraints on the evaluation of reservoir gas-bearing characteristics.Based on the geological characteristics of the deep Upper Ordovician Wufeng and Lower Silurian Longmaxi Formation,specialized experiments were conducted to determine key gas-bearing parameters.Interpretation models for deep shale porosity,water saturation,and adsorbed gas were established.Integrating field productivity results,a comprehensive evaluation standard for deep shale quality and gas-bearing characteristics was developed.This gas-bearing logging evaluation method has been widely applied in the Fuling Shale Gas Field and its surrounding areas.
