Abstract: In the light of continuous rising of watercut and decrease of formation pressure in mature heterogeneous sandstone oilfield, injection-production ratio must be adjusted above the reasonable lower limit of formation pressure so that better economic benefit can be obtained.A method for solving minimum formation pressure was given based on theory of oil production technology and production data in Shuanghe oilfield and performed well.It is showed that minimum pressure maintenance may be used as the basis for comprehensive adjustment in later period of oilfield development.
