摘要
低渗透油田储量在油藏总储量中占有相当大的比例,由于其储层物性差、渗流机理复杂,因而单井产量、采收率低,开发难度大。通过文献调研,总结了在现有技术条件下国内外低渗透油田开采方法的增产原理及增产效果,并进行了对比和展望。调研结果表明,国内外低渗透油田并没有局限在注水、酸化、压裂等传统开采方法上,而是在此基础上寻找适合各油田的改进技术,发展方向是高效、无污染的物理、化学及微生物方法。
The reserves of Low-permeability oil field occupies a significant proportion of total reserves.Because of its poor reservoir properties and complex seepage mechanism,its single well production and recovery is low,development is difficult.Through literature review,the principle and increasing effect of exploitation methods for low-permeability oilfield under the existing technology at home and abroad are summarized.The methods are compared and prospected.The results show that the low permeability oilfields at home and abroad don't limit the exploration methods to traditional ones such as water flooding,acidizing and fracturing,but to find improvement.The development direction is efficiently,pollution-freely physical and chemical and microbiological methods.
