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
