自主研发的Drilog随钻测井系统由随钻测量仪、工程参数测量仪及随钻电阻率伽马一体化测井仪组成;自主研发的Welleader旋转导向钻井系统由涡轮发电机短节、有线柔性短节、以及导向短节组成。2个系统配合用于勘探开发中,对提高钻遇率有重要作用。介绍了2套系统组合在某油田X井8.5英寸井段的使用过程,通过实时数据研究,分析了轨迹控制、动态轨迹测量、导向工具时效、随钻测井质量等应用效果。统计结果显示系统的钻进效率高,测量数据准确,证明了2套系统在定向井作业中的测井质量优良,实时地质导向效果良好。本次高难度作业为2套系统推广积累了应用经验。
The self-developed Drillog logging-while-drilling system consists of a logging while drilling instrument, an engineering parametric measuring instrument and a logging-while-drilling resistivity gamma integrated logging tool. The self-developed Welleader rotary steering drilling system consists of a turbine generator short section, Short section, and the leading short section. Two systems cooperate for exploration and development, to improve the drilling rate has an important role. This paper introduces the process of using two system combinations in the 8.5-inch section of an X-well in an oilfield. Through real-time data research, the application effects of trajectory control, dynamic locus measurement, guide tool aging and logging-while-drilling logging are analyzed. The statistical results show that the system has high drilling efficiency and accurate measurement data, which proves that the logging system of two sets of systems is good in the operation of directional well and the real-time geosteering effect is good. The difficult operation for the promotion of 2 sets of systems has accumulated experience in the application.
