Research Of Detailed Seismic Interpretation And Well Adjust Deployment On Ma Nan Area

Ma Nan area is located in Xinglongtai oil field at the southern end of its exploration and development work has been uninterrupted.In 2004 after the exploration and development,the effect is not satisfactory,is still in the exploratory stage.Exploration and development process on the one hand shows that with the exploration and development of the region is getting higher and higher,more and more difficult to find favorable targets,on the other hand also shows that the regional geological awareness remains to be further strengthened.There are many geological models in the Xinglongtai reservoir in the Ma Nan area,and the geologic model of the reservoir is not clear,the reservoir distribution and the depositional status are unknown.At present,the well pattern is easy to develop.The existing reservoir description can not meet the potential of the remaining oil in the late stage of the development of the block,and it is urgent to describe the seismic geology of the reservoir in detail,and to delineate the fault,section and study the structural style,and study and develop the remaining oil for the later stage Deployment of well pattern adjustment to provide seismic technical support.In this paper,the characteristics of residual oil distribution are analyzed,and the relevant basis of seismic geology is provided.The phase reservoir prediction is carried out for the target area.The tectonic interpretation of the application of seismic data is re-collected and processed three-dimensional seismic data.The reservoir prediction is predicted by the three-dimensional seismic fine interpretation and the 3D seismic reservoir prediction.Based on the fine explanation of structure,this paper studies the structural features,the prediction of sand body distribution and the comprehensive geological research,and finds favorable targets and puts forward the well position suggestions.Through this study,a series of achievements and achievements have been made in the stratigraphic division and comparison,reservoir deposition,characteristics of oil and water distribution,and so on.Through the three-dimensional fine structure,the structural features of this area are implemented,and the distribution characteristics of the fault system are clarified.The results of the structural interpretation are in accordance with the law of regional tectonic geology,which can explain the characteristics of the stratum and the characteristics of oil and water production.From the structural interpretation of the results of the map analysis,the area of the second member of the sand structure shows a good inheritance.Through the comprehensive geological study,this area is dominated by tectonic oil and gas reservoirs,butthere are also localized lithologic reservoirs.Although the exploration and development of the work area after nearly 40 years,the exploration location is obvious,but further analysis shows that the local micro-amplitude structure and the local lithologic reservoir is the favorable direction of the next step to adjust the potential.
