Reservioe Logging Evaluation Study On The Fourth Member Of Shahejie Formation In Block S

Liaohe oilfield in recent years,faced with effective exploration areas decrease,high exploration degree and exploration targets of complex exploration situation,expanding areas of exploration in old is imminent.After years of continuous exploration and development,in Area S sandstone rock mass has more than industry did well,new control reserves of 41.11 million tons,2015 new peoved reserves of 11.2382 million tons,the exploration prospect is very broad.In order to expand exploration results,identified on the basis of existing exploration results in old the west slope of the north extension to the exploration and thinking.But the present situation of exploration and lithology,small layer division difficulty understanding unclear,effective reservoir is difficult to divide the single well,distinguish with four relationships and other issues Has preliminarily established in 2015 Area S sandstone rock lithology identification,reservoir classification standard and parameter calculation model and calculation model for reservoir engineering quality,as the research work has laid a solid foundation.Using well logging method,in the joint core description and rock ore experiment,on the basis of making full use of already well drilling data,conduct lithology second interpretation,redrawing of single-well lithology;In addition at the second explanation,on the basis of lithology,comprehensive test,test,and other geological data of the logging,for secondary interpretation of the reservoir,reservoir parameter studies,the division of logging facies and reservoir engineering research quality,provide technical support for the whole exploration.
