Professinal Reservoir Description Of Nansanwan Oil Field,south Part Of Songlao Basin

Based on wanting to solve the current Nansanwan oilfield development problems, like not clear about the geology, water cut goes up quickly, big difference of permeability from different small layers, the well pattern not suitable for the current development, this article means to make clear of the Reservoir characters of Nansanwan oilfield, then figure out the right way to develop the oilfield properly, study out the oilfield need to the professional study about the reservoir characters, make clear of the Reservoir Geophisics, find the reservoir potential, then enhance the development resluts.Following the international reservoir study methods, based on the national oilfield development experience, combined with Geology, seismic, wireline logging and develoment wells testing information,under the theroy guidness of sedimentory,tectonic geology,and development geology, with the advanced engineering ways, descriped the Putaohua reservoir of Nansanwan oil field.Apply the "sedimentory corresponse, grades controll" methods, finished the small layers correlation and sand group correlation,built up the area's seimic time horizon. Based on comparing the detail conventional core description and well log geophics study, figure out the sedimentory phase as bench and shallow lake.Follow the procedure of core coresponding the logging,then logging mark the seismic data, got minus stucutre and small faults of top Putaohua reservoir with the 3D seismic information.After clearing of the reservoir sendiment phases,minus stucure,the single sand body distribution horizontally,by selecting the right geology model, build up the 3D single sand body model, according to the logging interpretation of oil layers,water zones or dry zones information, combined the zones testing and pressure testing information,make clear of the diffenrent sand develop characters.Knowing the oil sand bodys distribution horizontally.Based on the study results of well knowing of the reservoir,point out the oil richness area,take the right direction of the potential to produce more oil from.
