    Abstract:Shi?蒺nan 21 well area in Luliang Oil Field is an oil reservoir with mesopore, low permeability and extra-low permeability, water absorption capacity of its injection wells deteriorate gradually, water injection pressure increases gradually and there is lack of water injection more and more seriously. In order to solve the problem fundamentally, adopted is molecular film water injection technology to improve its water absorption capacity and enhance its water drive recovery. Field test results show that this technology can improve water injection development effect. Aiming at such issues existing in ordinary acidizing and de-plugging process as small processing radius and short useful life of the de-plugging agent, recommended is a strong penetration agent. It is suggested that the strong penetration agent is acidized and optimized technically and applied in combination with molecular film technology to solve water injection problem and improve water flooding recovery further.
