摘要：

辽河西部凹陷曙103块潜山由中元古界长城系高于庄组泥-粉晶白云岩、灰质白云岩和白云质灰岩组成,其主要储集空间为溶蚀孔洞、裂缝及微孔微缝等。根据碳酸盐岩储层的测井曲线特征,选择自然伽马、密度、声波时差及电阻率作为评价指标,对于不同的读数段赋予不同的分值。在对某一储层段进行评价时,先分别得出各项指标的分值,相加后再与储层评价标准对比,即可确定该储层段的类别。经与曙103块潜山各井的开采现状对比表明,该方法得出的储层评价结果是准确的。

Abstract:

Shu-103 block buried hill in west Liaohe Depression consists of Middle Proterozoic dolomicrite,lime dolostone and dolomitic limestone.Its main reservoir spaces include solution cavities and pores,fractures,micro pores and fractures.According to the characteristics of log curve of carbonate reservoir,gamma ray,density,acoustic and resistivity log curve are selected to be evaluating indicators,and endue different log data with different values.The segments of a reservoir is caluclated,then sum up the values of every curve and compare the results with criterion of the reservoir,the reservoir type could be determined.The results of this method is proved to be correct.

Key words: buried hill, carbonate reservoir, property, evaluation, log curve, west Liaohe Depression
