异常的井眼条件和特殊的地层性质所引起的异常测井响应往往无法识别,或产生错误的解释.仪器故障引起的异常测井曲线,本文不予讨论.本文将通过几个现场实例对标志储集层条件异常的自然电位和自然伽玛测井响应异 Abnormal logging conditions caused by abnormal borehole conditions and special stratigraphic properties are often unrecognized or incorrectly interpreted. Abnormal logging curves caused by instrument faults are not discussed in this paper. Natural Potential and Natural Gamma Logging Response to Abnormal Reservoir Conditions
