The Studying About Recovery Of Shan45 Field In Jingbian Gas Reservoir

Shan45 field located Jingbian gas reservoir is at last stage of stable production,while The degree of recovery in this field is too low.In Shan45 filed,petrophysical is terrible and diagenesis is strong and heterogeneity is awful.We cannot keep the same production rate in each layer caused by the situation mentioned in last word,and finally we cannot figure out the recovery in each layer and the recovery of flat.By this research,we want to figure out the development situation,the static reserves and dynamic reserves and finally to figure out the recovery of this field.So we study the Geological Features of this field first,that is the base of trying to figure out the distribution of reserve and the recovery of this field.After this work,considering many documents about geological,testing well,well logging and production,we try to choose better methods to calculate dynamic reserve and static reserve from many methods recommend by exports.we will study how to develop this filed in a scientific and advanced way further.After this research,we find the potential is unbelievable and the rest of reserve is 150×108m3 which is equals to all production to date.Shan45 field is low-permeability tight carbonate gas reservoir.Now,the well spacing is too close to develop some layer which is difficult to be developed.After Studying,on the one hand we should try to improve reservoir property,on the other hand we can adjust scheme of well pattern thickening.
