Fine Reservoir Descriping Research Saertu Ⅲ Group Of North-West Block In Lamadian Oil Field

In order to expand the second exploitation technique on the water flooding,this paperthrough reservoir fine description of Saertu Ⅲ group in North-West block which was wellpattern thickened. Understand the distribution of every variety sand bodies by usingmulti-subjects reservoir research technique to description the remaining oil in thick oil layer.Building up the data base of sedimentary units boundaries in North-West Saertu Ⅲ Groupwhich was thickened by well pattern, provide six sedimentary facies maps and statistics data.In the reservoir property modeling, carrying out the simulation of the sand body and reservoirproperty by determined the variation function of the change process which is according to thesedimentary environment and sedimentary mechanism of every variety sand body, under thecontrol of facies. Checking out three-dimensional geological model accuracy by geologicalreserves of inspection, the number of sand body layers and sand thickness contrast.Accomplishing fine description of the remaining oil reservoir by adjusting model to matchhistory of the block and well.This research provides an important technique basis which knows reservoir conditionfor technical personnel and draws up a development of oilfield. Actual work and the effectshowed that this method has apparent effect in actual application that will be provideddevelopment effect for block development effect.
