| 摘 要： | 根据白云岩中溶蚀孔、针状孔和晶间孔等主要孔隙的发育特征,可将塔里木盆地下古生界白云岩分为致密型、针孔型和孔洞型.3类白云岩在测井响应上有明显的差异,主要表现在常规测井值及曲线形态上.致密型储集性能最差,具有高电阻率、低中子孔隙度和高密度;针孔型一般具有低电阻率、高中子孔隙度和低密度,曲线形态一般呈"左凸"形;孔洞型比针孔型具有更好的储集性能,具有低自然伽玛值、低电阻率、高中子孔隙度和低密度,曲线形态一般呈"弓"形,而且双侧向电阻率曲线具有一定的幅度差.通过这些特征,建立塔里木盆地白云岩段孔洞识别测井模型.将该模型应用于巴楚和塔中地区的一些钻孔,取得了较好的效果不仅确定针孔型和孔洞型白云岩(储层)在纵向上的发育特征,还揭示了储集空间的发育程度,为进一步勘探开发提供了依据.

| Abstract: | There are vuggy,pinprick and intercrystalline pore in dolomite of the Tarim basin.Dolomite can be classified as compact dolomite,pinprick dolomite and vuggy dolomite by the characteristics of dolomite pore.Three types of dolomite are quite different in logging features,which can be showed in the data and curve shape of logging.Compact dolomite has the worst reservoir capability and distinct logging features:high resistance,low CNL and high density.Vuggy dolomite,low electric resistivity,high CNL,low density,zigzag shape of logging curve and obvious difference of dual-lateral electrical resistivity curve,has better capability and more obvious logging features than pinprick dolomite which has low electric resistivity,high CNL,low density and left or right protruding' shape of logging curve.The logging mode for pore identification of dolomite in the Tarim basin has been based on these characteristics.It is effective when the mode was applied to some wells in the Bachu and Tazhong areas,the reservoir lengthways distribution characteristic and the reservoir space degree of dolomite have been found.It is instructional for further oil exploration in the Tarim basin. |
