Qili Village Oil Field Table District 6 Reservoir Waterflood Effect Assessment

Low permeability reservoirs in our country generally reduce natural elastic energy.Water injection is referred to as maintain formation energy,improve the ultimate recovery of the reservoir is the most common way of mining.In the current and future quite a long period of time,water injection development will still be the main mode of oilfield development.So,for the workers engaged in the development of oil fields, research waterflood oilfield development effect is of great significance.Based on the extension of the oil field production plant in the seven village table 6reservoir district as the research object,The poor reservoir property,and the average permeability is lower than 10*10-3μm2.It is a typical low permeability lithologic reservoirs.Aiming at the existing problem of oilfield development,analyzed the development level and main control factors,Solve the block water cut increase and production development of contradiction is of great significance.Combining previous study of district 6 reservoir geology research,Analysis of the specific characteristics of the reservoir,On the basis of the formation,well pattern,waterflooding mode adaptive analysis,Waterflood oilfield development effect evaluation,Then adjust development plan,Finally,to make reasonable suggestions to improve economic efficiency.
