近几年来,海洋石油开发如火如荼,而大位移丛式井组成为开发井的普遍模式,即在一个井台上钻成十几或者几十口井同时开采,即密集型井组。在施工中从生产准备到完井,平台合理组织协调生产各环节的衔接,充分利用平台丛式井组特点,施行表层及油层交叉作业工艺,提高了钻井效率;采用优质聚合物海水钻井液体系,减少了摩阻,稳定了井壁,保证了电测及起下钻的顺利施工,减少了井下事故的发生,从而达到了安全优质快速钻井的目的。下面以埕北1GB井组为例进行简单分析。
In recent years, the development of offshore oil has been in full swing. However, the large displacement cluster has become the universal model for developing wells. That is, a dozen or dozens of wells are drilled at the same time, that is, intensive well groups. In the process of construction, from production preparation to completion, the platform reasonably organizes and coordinates the linkages in all aspects of production, makes full use of the characteristics of the platform cluster well group, implements the cross-working process of the surface layer and the oil layer, and improves the drilling efficiency; and uses high-quality polymer seawater drilling fluid system , Reducing the friction, stabilizing the shaft wall, ensuring the smooth construction of the electrical measurement and drilling, reducing the occurrence of underground accidents, so as to achieve the purpose of safety and high-speed rapid drilling. The following 1 埕 Kita Kita wells as an example for a simple analysis.
