Downhole Drilling Surveying Tools

  Product Description   Downhole Drilling Surveying Tools     Product Introduction                                        The product is used in the drilling process to measure the inclination, magnetic azimuth, tool face and instrument temperature and other parameters at downhole(measurement point) during drilling process.     This instrument belongs to self-floating fixed-point series products.   Accurate, time-saving, safe and convenient!     Suitable well conditions:   Minimum inner diameter of drill tools>60mm   Downhole temperature<125℃   Downhole pressure<95MPa     Benefits of self-floating operation mode            1)         Time-saving—compared with suspending operation mode, self-floating way doesn’t need mud circulation, which can save at least 30 minutes for each survey.   2)         Safe-- throughout the measurement process, you can always start the pump or lift and rotate the drill string. It won’t affect normal work of pulling the drill string from the hole, thus avoiding the occurrence of sticking accidents.   3)         Simple and convenient—No winch or pulley wheel are needed. One person can complete the whole survey work.       Features of Self-floating Fixed-point Electronic Inclinometers       1)        Self-floating fixed-point electronic inclinometer is a newly and specially developed electronic inclinometer by our company for the accurate measurement undercompositing drilling working conditions.   2)        Innovative—The measurement method is “fixed-point “way. The instrument will start measuring as long as the instrument arrives at the well bottom, which saves time. The fixed-point electronic inclinometer is an ideal replacement of the traditional timing type products.   3)        Accurate—“Fixed-point” measurement method can satisfy the measurement demand under different working conditions. It can complete a precise survey under the vibration of screw drills and guarantee a successful measurement data in just one shot.     Technical Parameters
