A Study On Sedimentary Characteristics Of The First Paragraph Of Baoquanling Group Formation Of Three-dimensional Area Fangzheng Fault Depression

Fangzheng fault depression is a double fault fault depression. It is petroliferous basins ofthe northeast region that which is complex structures. Paleogene Baoquanling mudstone arewell developed,cumulative thickness.Hydrocarbon source rocks has matured. Baoquanlinggroup is Fangzheng fault depression emphasis horizon.This study to carry out the research work of the five aspects.These are regional geology,stratigraphic classification and correlation, sedimentary facies of the signs and type ofsedimentary facies, sedimentary facies analysis, sedimentary characteristics and hydrocarbondistribution. This study analyzes the characteristics of regional stratigraphic and regionaltectonic evolution of the process, focus on the treasure section of the stratigraphic featuresand structural characteristics in the regional geological research. This study classification andidentification three sequence units, do sequence analysis of a single well and associated well,create a stratigraphic framework in stratigraphic classification and correlation. In terms ofsedimentary facies signs and types, summary and summed up treasure for some sedimentbuild environment to generate the conditions and characteristics, to identify the segment ofthe development of lacustrine facies fan delta faciesbottom of the lake fan facies. Research tocarry out single well facies analysis,and associated well-phase analysis of the peaceful face toclarify the sequence stratigraphic framework, depositional systems and reservoir distributioncharacteristics in sedimentary facies analysis. The study summarizes the distribution ofsedimentary facies relations, predicted Baoquanling group of oil and gas favorable areas, toprovide guidance for further exploration and development of fault depression for thefangzheng area.
