摘　　要：塔中地区下奥陶统碳酸盐岩地层发育岩溶洞穴,充填作用强弱不等,洞穴的有效性受到严重影响。针对此问题,根据既有资料建立了不同类型洞穴储层的交会图版,对洞穴储层进行有效性评价,从而为生产测试提供指导,极大地提高了经济效益。该方法在塔中地区取得了良好的效果。In the middle part of Tarim Basin the Paleokarst caves exist widely in the Lower Ordovician formation. Some of them have been filled with solid matter at different degrees so that the reservoir efficiency is influenced seriously. According to this problem, some cross plots have been constructed for the cave reservoir by the present data. They were used in estimating the validity of the cave reservoir and some suggestions were given for the formation fluid test, which can improve the economic benefit markedly. The method has an excellent effect in Tarim Basin.
