摘要
为了明确济阳坳陷博兴洼陷沙三下段湖相沉积的岩性特征,利用录井和测井等资料,优选出自然伽马、密度、声波时差、感应电阻率等多个对岩性敏感的测井响应曲线,采用两步岩性识别法建立岩性识别图版。识别结果表明:博兴洼陷沙三下段岩性多样,泥岩最为发育,碳酸盐岩含量次之,在深湖相可见富有机质纹层,认为沙三下中期识别后的灰质泥岩和泥质灰岩是页岩油的有利勘探层位。
In order to clarify the lithologic characteristics of lacustrine sediments in the lower member of the third member of Shahejie Formation in Boxing subsag,Jiyang depression,the lithologic identification charts are established using two-step lithologic identification method according to multiple logging response curves sensitive to lithology,such as natural gamma ray,density,acoustic time difference and induction resistivity.The identification results show that the lithology of the lower member of the third member of Shahejie Formation in Boxing subsag is diverse,mudstone is the most developed,followed by carbonate rock,and there are organic rich laminaes in deep lake facies.It is considered that calcareous mudstone and argillaceous limestone identified in the middle stage of the lower third member of Shahejie formation are favorable exploration horizons for shale oil.
