本文介绍双侧向—Rxo测井解释方法及其应用实例。从中可以看出:(1)在一定的条件下,用径向电阻率变化进行定性、定量地划分油、气、水层,是一种有效的方法;(2)深浅侧向对比是进行解释的基础,加上微球形聚焦测井资料,可以更完善地进行解释;微球形聚焦测井因受接触条件的限制,并非在所有的情况下都能正确地反映Rxo数值,必须与双侧向对比,才能可靠地进行解释;(3)文中均用厚层图板进行解释,实际上,层厚不同,解释图板相差悬殊,这一点应引起注意。—编者 This article describes the two-lateral-Rxo log interpretation and its application examples. It can be seen that: (1) It is an effective way to divide the oil, gas and water layers qualitatively and quantitatively under the certain conditions with the variation of radial resistivity; (2) The contrast between depth and depth is explained , Coupled with microsphere-focused logging data, can be more fully explained; microsphere-shaped focus logging due to contact conditions, not all cases can correctly reflect the value of Rxo, must be double-sided Contrast, in order to be able to explain reliably; (3) text are used to explain the thick plank, in fact, different layer thickness, explain the difference between the plank, which should be noted. -editor
