| 摘 要： | 依据可容空间(A)与沉积供给(S)比值的测井响应特征,结合标志层的特点,进行层序界面的类型划分、识别和测井响应特征的研究,并依据测井曲线的叠加样式,进行层序地层测井响应特征的研究研究结果表明,白音查干凹陷腾格尔组层序界面位于测井曲线基值发生明显改变的转折点上,大型河道冲刷面和进积与退积的相互转换面也是层序界面的发育位置最大湖泛面岩性表现为泥岩,在测井曲线上表现为高自然伽马(GR)、低自然电位(SP)、低电阻率(RT)的特点层序地层的测井响应特征中,进积类型测井曲线呈现漏斗型,表现为曲线的幅值由下向上依次增大的特征；退积类型测井曲线呈现钟形,表现为曲线的幅值由下向上依次减少的特征；加积类型测井曲线呈现箱型,表现为曲线的幅值变化不大
