摘要:
东海盆地西湖凹陷为典型的低孔低渗储层,地层压力系数求取困难,导致压稳计算难度高,增加了固井压稳准确计算的难度。同时受油基钻井液作业的影响,加剧了固井高效顶替难度。通过优化浆柱结构设计、开发高效冲洗前置液和聚合物防窜水泥浆体系,优选压稳防窜计算方法,形成了东海大位移井固井工艺配套技术,研究成果在东海进行了4井次的应用试验,固井质量优良,满足油气井后续开发需求。
Abstract:
The Xihu Sag in the East China Sea Basin is a typical reservoir with low porosity and low permeability,and it is challenging to obtain the formation pressure coefficient,making it more difficult to calculate pressure stability and cementing pressure stability accurately. The difficulties of effective cement replacement have also become more challenging as a result of the oil-based drilling fluid operation. For the extended reach wells in the East China Sea,the cementing technology includes optimizing the design of the slurry column structure,efficient flushing of the ahead fluid,anti-gas channeling cement slurry with polymer materials,and calculation method of pressure stability and anti-channeling. Four wells in the East China Sea have used this cementing technology,and the cementing quality is excellent,meeting the requirements of oil and gas wells for subsequent development.
