辽河西部凹陷曙 1 0 3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 1 0 3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。
The Shushan 103 buried hill in the western Liaohe depression consists of the Gaoyuzhuang mudstone dolomite, dolomitic dolomite and dolomitic limestone of the Paleoproterozoic Great Wall, with the main reservoir space being dissolved pores, cracks and micropores Micro-slit and so on. According to the logging curve characteristics of carbonate reservoirs, natural gamma, density, acoustic time difference and resistivity are selected as evaluation indexes, and different scores are given to different readings. When evaluating a certain reservoir section, the scores of each index are obtained first, and then compared with the reservoir evaluation standard after adding to determine the category of the reservoir section. The comparison of the mining status with the wells of the 1018 buried hills in Shuzhou shows that the reservoir evaluation results obtained by this method are accurate.
