低渗透油田注水开发工艺技术分析

摘要
石油是我国重要的工业能源,也是作为一种关系到国家经济命脉和国家经济安全的战略性物资,发挥着越来越重要的作用。近年来,中国经济和工业的发展越来越快,各行业对石油供应量越来越多,出现了不同程度的供不应求现象,这在一定程度上促进了中国油田的勘探开发进度。盲目追求原油产量,导致油田单井含水率呈现上升的趋势。油田产油量是开发过程中最重要的指标之一,为了保证油田稳产高产,就有必要优化注水工艺,改进油田的注水开发工艺技术,保证油田注水工作顺利进行。特别是对于一些低渗透性油田,油田注水工作更是重中之重,这样才能够及时补充地层能量,确保完成各项生产指标。本文首先对低渗透油田的特征进行了分析,然后分析讨论了低渗透油田注水的相关工艺技术,旨在指导和改进国内低渗透油田注水开发工艺技术。
Petroleum is an important industrial energy in our country, and is also a strategic material related to the lifeline and security of national economy, and plays an increasingly important role. In recent years, the economy and industry in China are developing faster and faster, and petroleum supply in various industries is increasing. There has been a phenomenon of different degrees of shortage in supply and demand, which has promoted the progress of exploration and development of oilfields in China to a certain extent. Blind pursuit of crude oil production has led to an upward trend of water content in single well. Oil production is one of the most important indicators in the development process of oilfields. In order to ensure stable and high production, it is necessary to optimize water injection process and technology, improve water injection technology and ensure the smooth operation of water injection. Especially for some low permeability oilfields, water injection is the most important work, so that formation energy can be supplemented in time, and ensure the completion of various production indicators. Firstly, this paper analyses the characteristics of low permeability oilfields, and then discusses the related water injection process and technology in low permeability oilfields, aiming at guiding and improving the water injection development process and technology in low permeability oilfields in China.
