Development Adjustment Scheme of a Low-Permeability Reservoir in the SN Oilfield

Due to the complexity of low-permeability reservoirs, there is no set established plans adjust development specific and final adjustment plan should be determined through comprehensive consideration many aspects. At present, reservoirs in SN oilfield faces problems. It urgent formulate corresponding improve current situation. In view problems surface oilfield, this paper used previous research results a reservoir for reference, evaluated effect, analyzed remaining oil distribution via numerical simulation, finally designed optimized plan. The show that injection–production ratio pressure were generally maintained, production decreased, water cut increased, recoverable reserves considerable; historical matching quality simulation was good. There more northeast J007 well block north J008 block, potential L2 L3 layers great. mainly concentrated areas with high positions, poor physical properties, imperfect patterns; predicted cumulative Scheme IV 15 years recovery highest, best effect highest economic benefit. This as oilfield. aim production, ultimate factor, benefits provide reference similar oilfields.
