渤中19-6构造位于渤中凹陷西南部，太古界潜山储层以火成岩、变质岩为主，常见花岗岩、花岗片麻岩等。地质、测井资料均表明岩性复杂，不同岩性的物理化学性质差异较大，给潜山储层有效性评价工作带来了挑战。为准确识别潜山储层岩性，总结了潜山储层主要岩性常规测井与电成像测井响应特征，结合RoqScan井场矿物实时分析技术，建立了一套适用于研究区的岩性识别技术，该技术在本区岩性识别实际工作中取得了良好的应用效果。

BZ19-6 structure is located in the southwest of Bozhong Sag, and its Archean buried-hill reservoir is mainly composed of igneous rock and metamorphic rocks, commonly including ganite and granite gneiss.Geological and logging data show that it is lithologically complex and different lithologies vary greatly in physical and chemical properties, which brings about challenges to the effective evaluation of the buried-hill reservoir.In order to identify the lithologies of the buried-hill reservoir, the response characteristics of the main lithologies in the buried-hill reservoir in conventional logging and electrical imaging logging were summarized in this paper.Then, based on RoqScan real-time wellsite mineral analysis technology, a set of lithology identification technology suitable for this study area was established.And its application to actual lithology identification in this area is satisfactory.
