调整井固井工艺技术研究进展
|
摘要
调整开发井主要用于老油田开发后期重组完善井网和实施层内细分开采,实现稳产和上产。受周围注采系统和生产现状影响,复杂的地层压力系统、多样的地层流体成分等导致调整井固井质量难以保证层间有效封隔。在分析调整井固井面临的各项技术难点以及对固井质量影响基础上,总结目前为保证固井质量所采用的主要技术措施和存在的问题,提出下一步可采取的技术措施与研究方向,为提高调整井固井质量奠定了技术基础。
Adjustment wells are mainly used for improvement of the well pattern through regrouping, and for fine production through subdivision of the pay-zone at the late development stage of the old oil fields so as to achieve stable or higher productivity. With the existing injection-production system and production status, the cement quality of the adjustment wells cannot ensure effective sealing between layers due to the complex formation pressure system and diverse formation fluid compositions. Based on the analysis of various technical difficulties faced by adjustment well cementation and their effects on cementing quality, this paper summarizes the existing problems with the cementing quality and the main technical measures to improve it at present, and put forward the technical measures and research directions to be taken in the next step, which lay a technical foundation for improving the cementing quality of adjustment wells.
