轮南地区碳酸盐岩储集层部分波动参数特征

塔里木盆地奥陶系碳酸盐岩储集层是近几年油气勘探证实的最有利的目的层之一。轮南地区奥陶系碳酸盐岩储集层属潜山风化壳类型，它经历了多次构造运动及成岩改造作用，物性在纵向横向上的变化都极其复杂，使得储集层预测非常困难。根据超声波测试、测井、地震及岩性资料，研究了纵波速度、品质因子、频率、振幅等波动参数与储集层的对应关系，发现、总结了它们之间的一些规律，为碳酸盐岩储集层预测提供了依据。

Characteristics of Partial Wave Parameters of Carbonate Reservoir in Lunnan Area

Ordovician carbonate reservoir in Tarim basin is one of the most favorable targets discovered in oil/gas exploration in recent years. It is of buried hill weathering crust type and underwent multiple tectonic events and diagenetic processes, so its petrophysical properties in both directions change irregularly and it is very difficult to conduct reservoir prediction. Based on ultrasonic wave testing, well logging, seismic and lithologic data, this paper studied the corresponding relation between wave parameter(P wave velocity, quality factor, frequency, amplitude) and reservoir, which offered basis for forecasting carbonate reservoir.
