The Study Of Oil Pool Geological Characteristics About Beizhong Sub-depression Area Of Hailaer Basin

The area of Beizhong sub-depression is located in the sourth of Hailaer basin,which is one of the most important gas and oil rich bed in Hailaer basin,Meanwhile,it is also one of the most important regions,which could increase reserves and production in Hailaer basin,In the future development precession of Hailaer basin it would occupy an important position.this study of theoretical guidance is Architectonic Geology, Geology of Petroleum, Deposition Geology, and Well Logging Geology. The studied target is Beizhong sub-depression area. Through the study of detailed structural and tectonic evolution history, we can understand the tectonic framework and evolution.Through the study of inversion and reservoir prediction,according the sedimentary facies we can know the reservoir type,rock properties and spatial distribution characteristics, provide an important basis for research.According to the detailed description of reservoir we can understand oil/gas/water reservoirs and reservoirs style,reservoir distribution.Through the plate of oil/water identification and the effective thickness and standard criteria to explain,we can provide technical support fo the evaluation of old wells and reserves review. So we can drill target selection, optimize well placement, summarize exploration results, and carry out the reserve study and overall evaluation of reservoir.On the basic of the study information about drilling core, well logging, well testing, testing for oil,oil/gas/water analysis, the majors carried out in-depth and detailed study about general geology, structural feature, fluid nature, reservoirnature,oil/gas/water distribution and reservoir style of Beizhong sub-depression reservoir and achieved some new understanding and new development, which would play a very important guiding significance for the development of Beizhong sub-depression area.
