摘要
本文根据仑圩开发区的开发实践,说明了小断块油田同样适宜早期注水保持油层压力的开采方法。根据不同的油藏类型采用不同的注水方式以及不同的注采比,确保油层在某一压力下生产。选择油井合理的流动压力,随时分析注采动态,在注水受效的前提下,适当降低流压放大生产压差,可提高油层的生产能力。充分利用油区有利条件,采取有效措施,使油井较晚见水,对实现较长时期的高产稳产起到了积极的作用。
This paper demonstrates that a small block-faulted oil field can be water flooded to give a high efficiency recording the field practice of Lunxu oil field. Different flooding pattern and different injection production ratio are used for different reservoirs to maintain the reservoir at a reasonable level.Reasonable flowing pressure and production pressure differentials are selected to give a higher production capicity of the production wells after the water flooding effect is observed.Effective measures are taken to delay the water breakthrough in production wells taking the adventage of low oil viscosity and water wet characteristics of the reservoir,so that peak production has been kept at a longer period.
