Detailed Layered Sedimentary Facies Study Of Urxun Sag

Based on internal sequence of urxun sag structure,sedimentary structure understanding is still not very difficult factors such as system,in the practical exploration and production need more system to understand the internal structure of the region and the sedimentary structures,this study employs sequence stratigraphy,sedimentology,tectonic stratigraphy,petroleum geology and other multi-disciplinary theories and methods,the integrated application of logging data,logging data and geological data and 3 d seismic interpretation data,the existing research results,divided into on the basis of sequence,the copper bowl urxun sag temple to turn large grinding river group a level 4 sequence stratigraphy of the identification and classification;Establish research as detailed within the sequence comparison framework,studied the distribution of sedimentary facies in the area and favorable zones in the studied area is predicted;Accurately in this paper,the sedimentary system in the study area within the sedimentary facies and favorable zones of reservoir sand body distribution in sequence framework;Discussed stratigraphic sequence,sedimentary facies belt distribution,controlling factors,reveal the internal fault depression basin tectonic setting of the basin filling and response process of lake evolution,so as to establish a prediction for regional distribution of favorable reservoir has the important function of downfaulted lake basin quaternary sequence stratigraphy model;Combined with the practical application,research of exploration and production,reservoir and cover the region development pattern,the study area for the future of the oil and gas exploration,provide reliable theory for non-structural oil-gas reservoir prediction and basis.
