摘　　要：为加快川中北部震旦系气藏整体勘探进度,缩短建井周期,广泛运用PDC钻头+高效螺杆+优质钻井液体系等新工艺和新技术,给快速准确地进行地层划分和对比提出了严峻的挑战。为适应钻井新技术的要求,开展区域地层跟踪分析研究,形成随钻地层划分对比与预测技术,为高效、平稳地推进川中震旦系的油气勘探工作提供科学指导和技术支撑。In order to speed up the overall exploration progress and shorten the well construction period of the Sinian gas reservoirs in the northern Sichuan Basin,It has been widely applicated that new process and technology of PDC bits+efficient screw+quality drilling fluid system,which brings the serious challenges of quickly accurate stratigraphic division and correlation.To meet the requirement of the new technology of drilling,we carry out the regional stratigraphic tracking analysis research,and establish the technologies of stratigraphic division,correlation and prediction in drilling process.to promote the work and provide scientific guidance or technical support.of the Sinian gas exploration in northern Sichuan area.
