1Sedimentary hydrodynamic study of sand bodies in the upper subsection of the 4th Member of the Paleogene Shahejie Formation in the eastern Dongying Depression, China显示文摘Petroleum is produced from a beach-bar sand reservoir in the upper subsection of the 4th member of the Paleogene Shahejie Formation(Es4s) in the eastern Dongying Depression, penetrated by many wells in the Guangli-Qingnan area and this subsection still has further exploration potential. Using drilling and logging data, we analyzed the sand body types, emphasizing the sedimentary characteristics of the beach-bar sand bodies. Combining these data with the concepts of lacustrine and oceanic hydrodynamics, we explain the formation and distribution of the beach-bar sands in the eastern Dongying Depression. The connectivity between beach-bar sand bodies within each individual hydrodynamic zone is better than that between sand bodies in any two adjacent zones. The tempestite sand bodies developed in this area are characterized by typical storm deposits and are located at the bottoms of the beachbar sand bodies. They grade upward to normal shore and shallow-lacustrine beaches and bars. We also propose a new simple method to estimate the paleo-water depth using the thicknesses of the bar sand bodies in parasequences combined with the principle of hydrodynamic zonation. Based on the distribution of the beach-bar sands in parasequence set 3, we infer that the paleo-wind direction was from the north with an average paleo-wind force of 6 when the major beach-bar sand bodies formed.Jiang Zaixing Liang Shuyi Zhang Yuanfu Zhang Shanwen Qin Lanzhi Wei Xiaojie 2014Petroleum Science2014,11,2:16
2Sedimentation Rate Rhythms:Evidence from Filling of the Tarim Basin,Northwest China显示文摘Variations of sedimentation rate within a basin over geologic time are a time series that can be filtered into several cyclic wave curves. Based on back-stripping and the empirical mode decomposition method, the cores from 14 wells in the Tarim Basin were selected to do filtering analysis. Four cycles or quasi-cycles(33 Ma, 64.4 Ma, 103.6 Ma, and 224 Ma) were obtained. Among these, the 33 Ma period, which was related to the internal earth activity, an external force, or a combination of the two, was the most obvious. The 64.4 Ma period corresponded to the solar system crossing the galaxy plane or the periodic melting of inner-earth material. The 103.6 Ma period was related with plate collisional tectonism around the Tarim Plate. The 224 Ma period was related to one galaxy year and may also be related to the aesthenospherical convection cycle.CHEN Shuping JIN Zhijun WANG Yi ZHOU Ziyong LI Jingchang YANG Weili 2015Acta Geologica Sinica(English Edition)2015,89,4:6
3页岩小层水平井对比及其构造三维可视化表征显示文摘页岩气建产区是以平台+水平井的井工厂模式运营的,利用水平井开展页岩小层对比及其结构与构造建模,在目前还是一项亟待攻关的技术难题。在解析页岩小层结构特征基础上,建立了页岩小层分层模式和水平井测井多井三维可视化对比方法,依靠井-震结合,实现了页岩小层结构与层面构造的三维建模,形成了井工厂模式下页岩气建产区小层结构与层面构造三维可视化表征新技术。成功完成了四川盆地W页岩气田某典型建产区6个页岩小层分层模式的建立、水平井多井可视化对比,以及页岩小层结构与7个小层层面构造模型的建立。在证实该技术实用性及可靠性的同时,还为研究区后期的精细化生产管理提供了构造模型基础。欧成华 杨晓 梁成钢 黄毅 朱海燕 2019西南石油大学学报(自然科学版)2019,41,6:4
4准噶尔盆地腹部SN13井区井震时深关系“异常”分析显示文摘准噶尔盆地腹部目的层侏罗系为砂泥互层,各向异性条件成熟,井震标定时发生时深关系“异常”,一定程度上对地质勘探研究产生不利影响。首次在该区开展了各向异性叠前深度偏移,通过时间域基于微测井静校正精度分析评价,结合深度域井震各向异性叠前深度偏移时深关系分析,认为井震结合各向异性叠前深度偏移可有效提高该区成像精度。实际资料证明该区出现井震时深关系“异常”的合理性,为后续地质勘探研究工作提供了资料分析依据。窦强峰 马国财 杨晓海 刘宜文 2020新疆地质2020,38,4:1
