| This paper starts from the structure,reservoir,sedimentary and reservoir distribution,static and dynamic comprehensive research on reservoir in wellblock Huang 20,by depicting the overall deeply on the geological characteristics,the geology and the development and refinement of the property to reservoir further,establishing reservoir geological model and the distribution of remaining oil is reliable.And to determine the potential yield of the oil field next,provides the optimal scheme for reservoir development.The study is based on the drilling data,combining with the seismic data,makes a comparative study of the division of the stratum statistics and the comparative study block layer;in the stratigraphic division and comparison on the basis of sequence stratigraphy,the isochronous stratigraphic framework;re interpretation of the fault system using seismic data of high resolution the rate in small layer unit;sedimentary microfacies;combined with the area of large,complex structure,oil and gas layers,the regional character in the background of slope state,grasping the process.By studying the formation and distribution of reservoir and different sedimentary systems,the overall anatomy,macro control,to seize the high layer region of the system layer,fine structural interpretation and reservoir distribution as the main line,the establishment of oil reservoir level body frame;and to block for reservoir description,subdivision,secret agents so,prioritize,focus.Through the above work,the first member of the Shahejie formation is divided into 33layers: the upper,middle and lower sub section,and the 31 member of the Shahejie formation is divided into the following 15 sections: the first section of the Shahejie formation is divided into 19 layers,and the first one is divided into three layers.The structure,sedimentary environment,reservoir,reservoir type and remaining oil distribution were re established,the well area was adjusted,and 6 new wells were deployed. |
