摘 要:相比于常规储层,页岩气储层具有低孔低渗且含气性复杂的特点,为页岩气储层的测井评价

增加了难度。为了系统性的研究页岩气储层的测井评价方法,以加拿大西加盆地页岩气储层为研究对象,

针对页岩气储层特点,同时考虑到页岩气开发的实际需要,确定页岩气储层系统性的测井评价模型包括储

层物性参数模型、地球化学模型、含气性模型和骨架矿物组分模型等。根据体积模型与数值回归分析分别

建立基于测井资料的页岩气储层评价模型,确定研究区的页岩气储层测井评价体系。通过评价结果与实

测结果的对比来检验模型的实用性与准确性。应用效果表明:页岩气测井评价模型具有良好的准确性,能

够为页岩气开发提供良好的支持。

Abstract:Shale gas reservoir is characterized by low porosity ,low permeability and complex gas ,while

compared with conventional gas reservoirs ,which adds difficulty to the logging evaluation of shale gas

reservoir .In order to study the systematic logging evaluation method of shale gas reservoir ,shale gas reservoir in the west Canadian basin is selected as the study object ,four aspects logging evaluation p arameters of the shale gas reservoir are determined by taking into account the actual development of shale g as and particularity of shale gas reservoirs .Logging evaluation model of geophysical reservoir parameters ,g eochemical ,g as ‐bearing and matrix mineral component are established on the base of the theoretical Volume

model and numerical regression analysis ,finally establish the evaluation system of shale gas reservoir in the west Canadian sediment basin .By the analysis and comparison of the results from the laboratory and logging evaluation model ,the accuracy and practicability of the evaluation model for shale gas reservoir parameters

are verified .The practical application results show that the reservoir logging evaluation model based on the

logging data has good accuracy ,which can provide good support for the development of shale gas . Keywords:shale gas ;reservoir characteristics ;TOC ;adsorbed gas ;free gas ;matrix mineral composition
