The wire-line coring tool of HSQ serial has kept up the technical features of conventional placer drills and derived the advanced structure from steel cable fishing tool for inner barrel. HSQ系列绳索取心钻具,既保持了现用砂钻钻进的工艺特点,又发挥了钢绳打捞内管技术的方便性。
According to core observation and analysis of logging data and coring results of evaluation well, the classification criterion of restraining barrier and interbeds in shallow water delta facies was built up and they were divided into four types. 通过岩心观察,结合评价井的测井资料和取心分析结果,建立了浅水三角洲相隔夹层的划分标准,将其划分成四种类型。
Coring operations in several oilfield show that the software meets the in-situ coring requirement, and its error of coring depth in target zones is less than 4 cm, so reaching up the accurate location and coring in 20 cm thin beds. 通过在多个油田试用,该软件达到现场取心施工的要求,取心目的层深度误差小于4cm,实现20cm薄层的准确定位取心。
The paper presents the operational process of systematic coring, and sums up the experience of coring in the unconsolidated formation from analyzing each technical links in the coring. 文中介绍了系统取心的施工过程,通过详细分析取心的各个技术环节,总结出松散地层取心经验。
