十余年来,随钻数据采集技术的突飞猛进大大改善了钻井数据和地层数据的质量,数据采集范围进一步拓宽,使作业成本大幅度降低,提高了找油找气的效率。这是一种让钻头长慧眼的技术,它边钻边测,不占用钻井时间,能够实时地测量各种钻井参数和地层参数,不仅使地层评价更加真实可靠,让钻头“盯”住目标,沿设计轨迹钻进,而且还以其独有的慧眼,按实际地层情况选择最佳轨迹与目标。早期的随钻测量技术(MWD)只能测取钻压、扭矩、井深、井斜、方位和工具面角等钻井参数,适用范围十分有限。如今,随钻测量井下仪日趋小型化,最小 Over the past decade, the rapid progress of data acquisition technology while drilling has greatly improved the quality of drilling data and formation data, further widened the scope of data collection, significantly reduced operating costs and improved the efficiency of finding oil and looking for gas. This is a technology that allows the drill bit longer eye, it does not take drilling time, can measure a variety of drilling parameters and formation parameters in real time, not only makes the formation evaluation more realistic and reliable, so that the drill bit “stare” live Goals, drilling along the design trajectory, but also with its unique eye, according to the actual formation of the best trajectory and target selection. Early MWD measurements only measured drilling parameters such as WOB, torque, well depth, well inclination, azimuth and tool face angle, and the application range was very limited. Nowadays, downhole gauges are becoming smaller and smaller while drilling
