测井分析家和地质学家通过测井资料的综合解释来认识地层的岩性和含油性。但是,在新探区的探井和新的层系中,单凭测井曲线和测井经验是难于准确判断复杂的地质构造形态和岩性剖面的。因此,井壁取心技术已成为及时准确地判断疑难层的岩性和含油性的重要手段。 Well logging analysts and geologists know the lithology and oiliness of the formation through a comprehensive interpretation of log data. However, it is difficult to accurately judge the complicated geological structure and lithology profile based on well logging and logging alone in the new exploration area and new strata. Therefore, borehole coring technology has become an important means of judging the lithology and oiliness of difficult layers in time.
