中国西部及南方海相油气探区资源丰富,前景广阔,是中国石化实现油气资源战略接替的重点展开区域,一些区块地质环境恶劣,构造复杂,储层埋藏深,大大增加了钻井施工的难度。而这些探区所钻深井数量较少,可借鉴的钻井经验少,没有形成规范的钻井作业方法。所以,因钻井事故处理及报废井影响了这些探区的勘探开发进程。 The western and southern marine oil and gas exploration areas are rich in resources and promising. They are the key areas for the strategic success of Sinopec’s oil and gas resources. Some of the blocks have poor geological conditions, complex structures and deep buried reservoirs, greatly increasing the difficulty of drilling construction . However, the number of deep wells drilled in these exploration areas is less, less drilling experience can be learned, and no standardized drilling operation method has been formed. Therefore, due to drilling accident handling and waste wells affect the prospecting process of these exploration areas.
