Abstract (English): The existing direct push storage logging systems generally lack real-time monitoring capability for downhole tool status. The operation is essentially carried out in a "blind logging" state, making it impossible to accurately identify the location of a failure or the operational status of the tool in the event of sticking or blockage. This poses a risk of logging failure. To address this limitation, a measurement while drilling (MWD) system was integrated with the direct push storage logging tool, leading to the development of a direct push storage logging system with real-time monitoring capability. The system consists of a surface acquisition system, MWD tools, and a direct push storage logging tool. It employs 2PSK continuous drilling fluid pulse modulation and adaptive filtering signal extraction technology to achieve real-time uplink transmission of key parameters, including downhole tool communication status, operating voltage, current, and tension/compression load, etc. Field tests were conducted in four wells in the Tarim Oilfield, with a maximum well depth of 8771 m, a maximum downhole temperature of 178 °C, a maximum bottomhole pressure of 98 MPa, and a maximum operation duration of 66 h. During the logging operations, real-time monitoring of the logging tool status was successfully achieved, enabling accurate identification of tool sticking or blockage conditions. This provided a basis for on-site operational decision-making and significantly improved logging success rates and operational safety in complex wells. To address the current issue of low drilling fluid pulse transmission rates, it is recommended that future research focus on high-speed wireless transmission technology to further enrich the types of real-time monitoring data.

Abstract (Chinese): 现有直推存储式测井系统普遍不具备井下仪器状态实时监测能力, 作业过程处于"盲测"状态, 遇阻遇卡时无法精准判别故障位置与仪器工况, 存在测井失败风险。为此, 将随钻测量 (MWD) 系统与直推存储式测井仪器融合, 研制出具备实时监测功能的直推存储式測井系统。该系统由地面采集系统、MWD 工具及直推存储测井仪组成, 采用 2PSK 连续钻井液波调制方式与自适应滤波信号提取技术, 实现井下仪器通讯状态、工作电压、电流及张压力等关键参数的实时上传。在塔里木油田 4 口井进行了现场试验, 最大井深 8771m, 最高井温 178℃, 最大井底压力 98MPa, 最长作业时间 66h, 测井过程中可实时监测测井仪器的状态, 精准判别了仪器遇阻、遇卡工况, 为现场施工决策提供了依据, 显著提升了复杂井测井成功率与作业安全性。针对当前钻井液脉冲传输速率偏低问题, 建议后续开展高速无线传输技术研究, 进一步丰富实时监测数据类型。 [ABSTRACT FROM AUTHOR]
