对于注水开发的油田,除要有一套先进合理的注水工艺流程和管理技术外,注水水质的好坏也是十分重要的,或者说是关键问题之一。本讲着重谈谈注水水质的有关问题。一、对注水水质的一般要求不同的油田、不同的油层对注水水质有不同的要求。但最主要的要求是注入水不造成地层的堵塞,不使地面、地下管道及设备腐蚀和结垢。总的说来,应考虑以下几个方面: 1、注入水中固体或胶状物质的含量少;
For the development of oilfields, in addition to have a set of advanced and reasonable water injection process and management techniques, the quality of water injection is also very good or bad, or one of the key issues. This talk focuses on the quality of water injection related issues. First, the water quality of the general requirements of different oil fields, different reservoirs on the water quality has different requirements. However, the most important requirement is that injection of water will not cause formation blockage and will not corrode and scale the surface, underground pipes and equipment. In general, the following aspects should be considered: 1, the content of solid or gel injected into the water is small;
