自攻螺钉的连接.芯孔直径的参比值和用途 - In this paper , the author paticular analysis 11 core holes and established the partition of strutum gyration of key layers in the area , then stratigraphic analyzed the 225 well and identified microfacies of the target area , then established the mode of facies . the author analyzed the evolvement law of different type of channel combined sedimentary environment
本文首先通过对11口取芯井的详细解剖，确立了研究层段的层序地层格架划分方案，进而对研究区225口井进行了精细划分对比，进行了不同类型河道所处环境的微相识别与划分，并建立了研究区的相模式。 - Through the analysis of petrology characteristics and individual well section of sedimentary facies of five core holes , direction of sedimentary source area , the depositional framework and main facies types and its features of penglaizhen formation , baimamiao - songhua area are elaborated on the basis of sedimentary backgroud of region . from this above , in view of the study of the correlation of 3 cross sections of sedimentary facies , it is pointed out that distribution regularities of sedimentary facies and possible places of distribution of sand bodies of iii , iv member of penglaizhen formation are vertically and laterally developed in baimamiao - songhua area . by the analysis and contrast of seven plans of sedimentary facies and nine isopach maps of sandstone , the planar characteristics of distribution of sedimentary facies are summarized , meanwile , macroscopic distribution regularities of sand bodies is studied in iii , iv member , penglaizhen formation of baimamiao - songhua area
通过5口取心井的岩石学特征、单井剖面相分析，结合区域沉积背景，阐述了研究区蓬莱镇组的物源方向、沉积格局、主要沉积相类型及其特征；在此基础上，通过3条连井剖面的沉积相对比研究，揭示了研究区蓬段、蓬段纵向与横向上沉积相的分布规律及砂体的大体分布位置；通过7张沉积相平面图、 9张砂岩等厚图的分析对比，总结了蓬段、蓬段沉积相的平面分布特征，宏观上研究了蓬段、蓬段的砂体展布规律。
