Middle-Term Base-Level Cycle Sequence Filling Types and Response of Sedimentation-Sequence: An Example of Member 8 of Lower Shihezi Formation in Northwest Ordos Basin
摘要
Abstract
Based on the data from field outcrops, well logs and drilling cores combined with the theoretical basis of the stratigraphic and sedimentary process-response dynamic principles, one super long-term cycle is identified in the Lower Shihezi Formation in northwest Ordos Basin by applying the theory and technology of the high-resolution sequence stratigraphy on base-level cycle. Member 8 of this formation, one of the main gas-bearing members, is divided into two long-term, four middle-term and several short-term cyclic sequences. To analyze this member in the study area, detailed study is made on its different filling types based on middle-term base-level cycle as one cycle. Then further analysis is conducted on the response of sedimentation-sequence in fluvial-delta depositional system of the period. Consequently, architecture model of sedimentation-sequence in fluvial-delta facies has been established based on middle-term base-level cycle, to profound understanding the spatial-temporal relationship.关键词
