对于水驱开发油田,注好水、注够水、有效注水是保证油田高产稳产的重要保证,由于油田构造特性和储层物性的差异,以及管理方式欠合理和工艺技术水平制约等因素,导致随着油田开发时间的延长,无效注水对综合含水率、采油速度、采出程度都有直接影响,严重影响了油田的高效开发。因此,及时准确的分析无效注水形成的原因,有的放矢的采取合理的治理措施,提高注水开发水平,夯实油田稳产基础,保证油田高效可持续发展。
For the waterflooding development of the oilfield, water injection, water injection, effective water injection is an important guarantee to ensure high and stable production of the oilfield. Due to differences in structural properties and reservoir physical properties of the oilfield, as well as due to inadequate management practices and constraints of technology levels, With the extension of oil field development time, invalid waterflooding has a direct impact on the comprehensive water cut, oil recovery rate and production recovery, which seriously affects the efficient development of the oilfield. Therefore, timely and accurate analysis of the reasons for the formation of invalid water injection, targeted to take reasonable control measures to improve the level of water injection development, solid foundation to stabilize the oil field to ensure efficient and sustainable development of the oil field.
