    摘要:

    无隔水管泥浆回收系统可以实现在开路钻井工况下进行泥浆回收循环再利用,具有安全环保、简化井身结构和降低钻探风险等优点。该技术在国外已发展多年并成功推广工业应用,国内目前尚处于跟踪研究阶段。本文介绍了我国首套400 m级无隔水管泥浆回收系统设计研发过程,并通过海试试验验证系统的各项功能及指标。结果表明,所研设备样机搭载于“海洋地质十号”船,设备装船适配合理,最大海试水深384.7 m,设备各项功能性均符合设计要求,成功实现泥浆液位的识别与自动控制功能,全流程验证无隔水管泥浆回收循环钻井技术可行性。

    Abstract:

    The riserless mud recovery system can realize the recovery and recycling of mud under open drilling conditions, which has the advantages of safety and environmental protection, simplified wellbore structure and drilling risk reduction. This technology has been developed abroad for many years and successfully promoted in the industrial application, however, China is still in the stage of tracking research. This paper introduces the design and development process of first 400m riserless mud recovery system in China, and verifies the functions and indicators of the system through sea trial tests. The results show that the prototype of the developed equipment is equipped on the “Marine Geology-10” ship, the equipment loading is reasonably adapted, the maximum sea test depth is 384.7m, the functions of the equipment meet the design requirements, the identification and automatic control function of mud level are successfully realized, and the feasibility of riserless mud recovery and circulation drilling technology is verified in the whole process.
