丛式井组防碰绕障技术中的监督管理

Supervision and Management in Collision Prevention Technology of Cluster Well Group

随着油田勘探开发速度的提升,井网逐渐加密,气井开发区块受地理条件的限制,大多采用丛式井组密集分布开发,丛式井组的防碰绕障井口数逐渐增加,现场定向人员技术措施和能力要求更高,同时给监督管理工作也带来了巨大的挑战。根据近几年监督区块的教训和经验,总结研究出了一套现场应用的防碰绕障技术措施,包括井身结构设计、井组排序及MWD监测仪器软件的应用,在防碰绕障工作中取得了明显的效果。

With the upgrading of oilfield exploration and development speed, the well pattern density is gradually increased, and most of gas well blocks are developed by cluster wells due to the restriction of geographical conditions, which puts forward higher requirements for drilling technology and the ability of technicians, at the same time, also brings great challenges to the supervision and management of drilling engineering. According to the lessons and experiences of the blocks supervised in recent years, a set of on-site collision prevention technical measures are proposed, including the design of wellbore structure, the sorting of well group and the application of MWD monitoring software, and the obvious application effect of the measures has been achieved.
