Application of High-Resolution Sequence Stratigraphy in the Strata Correlation with Mud Logging While Drilling
摘要
Abstract
It is difficult to achieve fine exploration and development by the field strata classification and correlation with mud logging while drilling due to the influences of development mode adjustment,reservoir type and other as-pects in the eastern wellblock of Shengli Oilfield. High-resolution strata correlation with mud logging while drilling is implemented on the basis of high-resolution sequence stratigraphy theory. The upper sub-member of Sha4 forma-tion is classified into 1 long-term,3 medium-term and 6 short-term datum cycles. A high-resolution isochronous stratigraphic framework for this area is established to obtain the isochronous classification and correlation of strati-graphic sequence.Research indicates that the medium-term datum cycles control the sandbody superimposition pat-tern and lateral distribution,which is beneficial to the field strata classification and correlation with mud logging while logging. The short-term datum cycles control the sandbody type,which is considered as an significant basis for hydrocarbon reservoir prediction. This research could provide certain theoretical and practical references for the stratigraphy analysis and interface identification in Shengli Oilfield.关键词
