The Fine Structural Interpretation Of Quantou Group In Xinmu Area

According to the geological characteristic of Mu101 well field of Xinmu oilfield,this paper is based on the sequence stratigraphy,seismic data.Combining drilling data with logging data,this paper focus on the fine structure interpretation of the top of Quan III and Quan ? as well as the third layer of Quan ? by using the technical method which is multidisciplinary osmosis and comprehensive integration.According to the situation of Mu101 well field,this paper further implement the pattern of minor fault and micro structure of Quan? and Quan ? by acquiring the seismic data.Through the 3D high resolution fine structure interpretation of Mu101 well field,We could fully understand that the faults of the region of interest are almost nearly south-north strike normal faults and the faults appear as symmetrical graben faults as a result of the complex fault systems.The structural feature of Quantou formation of Mu101 well field is nosing structure.This structure is asymmetrical which the dip of north is bigger and the dip of south is smaller.The west part of the entire structure is higher than other directions and it begin to incline toward to the other three directions.Every seismic horizon has better inheritance.Dividing structural belt and associated structural belt has the same sedimentary features.It lays a foundation for deep fine structure interpretation.On the basis of the conventional 3D seismic,according to the requirements of 3D seismic interpretation,this paper use Discovery software to make fine composite recording calibrate horizon.Use slice technology and 3D visualization technology to determine the combined patterns and space distribution of faults.Well-seismic integration layer correlation technology supports the layer tracking.And it also offer assertive evidence to layer correlation which is using logging data.Expand the space of exploratory development and evaluation of Quan ? and Quan ?.Locate the accumulation of oil&gas.
