中文摘要:中海油服自主研发的Drilog?随钻测井系统由MWD系统、DSM参数仪，以及ACPR电阻率伽马组成，该系统已成功作业上百井次。为提高机械钻速ROP，挂接更多高端成像仪器，中海油服自主研发了HSVP?高速泥浆脉冲遥传系统，包括井下仪器及地面解码系统，经过水循环测试及实钻测试，可实现12 bps实时解码。在油气田勘探开发中，高速泥浆脉冲器可提高井地传输效率，有助于及时调整井眼轨迹，对提高油气田单井产量，提高采收率发挥重要作用。文章介绍了高速泥浆脉冲器在山西页岩气田某井81/2 in井段的使用过程，根据MWD系统上传数据，分析轨迹控制、动态轨迹测量、随钻测井质量等效果。结果显示HSVP?系统的钻进效率高，上传速率快，定向及时准确，证明了系统在钻进过程中测井质量优良，为系统的扩大使用积累了作业经验。

Application of high-speed mud pulse transmission technology in LWD
Abstract:The Drilog? LWD developed by COSL consists of MWD, DSM and ACPR, and have already been put into operation for hundreds of times. In order to improve ROP and incorporation of more high-end imaging instruments, COSL has independently developed the HSVP? high-speed mud pulse telemetry system which includes the downhole instrument and the surface decoding system. Water circulation testing and field trial demonstrate that it can realize real-time decoding at 12bps. In the exploration and development of oil and gas fields, the HSVP? can improve the transmission efficiency from downhole to surface; thus, helping to control the drilling trajectory real time, and contributing to the single well productivity and recovery. This paper introduces the use of the high-speed mud pulse tool over the 81/2in section of a Shanxi shale gas well. According to the data from the MWD system, analysis is made of the results from trajectory control, dynamic trajectory measurement and logging while drilling quality. The results show that the HSVP? system has high drilling efficiency, fast transmission rate and timely and accurate orientation. It has been proven that the logging quality of the system is excellent during the drilling process. The field use of the tool has also accumulated experience for the further use of the system.
