摘要
在勘探开发生产过程中,低渗、特低渗储层比中、高渗储层更容易受到伤害,并且,储层受到伤害后要解除伤害也更加困难。所以,要提高储量占我国油气总储量四分之一左右的低渗、特低渗储层的勘探开发效果及效益,搞好低渗、特低渗储层的保护工作就尤为重要。要搞好保护油气层工作的前提,是要对待保护储层的潜在伤害问题进行比较清楚的认识。对全国各油田进行的低渗特低渗储层的潜在伤害评价资料进行了比较全面系统的分析研究,确定出了我国低渗特低渗油田的主要潜在伤害问题,提出了在勘探开发生产过程中减轻这些伤害的对策,以便为勘探开发生产过程中开展低渗特低渗储层的保护工作提供必要的参考依据。
In the production process of exploration and development,it is easier for the reservoirs of low permeability and extremely low permeability to get damaged than for the reservoirs of middle and high permeability.Besides,it is more difficult to remove the injury when the reservoirs are damaged.Since the reserves of the reservoir of low permeability and extremely low permeability account for one quarter of the total oil and gas reserves in our country,to improve the effect and benefits of exploration and development for these reservoir,it is very important to protect the reservoirs of low permeability and extremely low permeability well.Clearly,the prerequisite for doing the oil reservoir protection well is to clearly understand the potential damage problems in the protection of oil layers.Therefore,the more comprehensive and systematic analysis and research are carried out based on the evaluation data about the potential damage in the reservoirs of low permeability and extremely low permeability all over the country.Then main potential damage problems in the oilfields of low permeability and extremely low permeability in our country are determined,together with the presentation of countermeasures about reducing these damages in the production of exploration and development.The purpose of research is to provide some necessary reference basis for the protection of the reservoirs of low permeability and extremely low permeability in the production of exploration and development.
