When the instrument is lowered to 200m from the bottom of the well, the lowering speed should be reduced. 5.2.7 When the instrument is lifted 150m from the pipe shoe or wellhead, the cable lifting speed should be reduced to lift the instrument out of the wellhead. For production measurement, when the instrument is 50m away from the wellhead, the winch should be turned off and the instrument should be pulled into the blowout preventer by manpower. 5.2.8 The power supply of the wellhead winch shall not be turned off before the instrument is lifted out of the wellhead, and the construction equipment shall not be disassembled in advance. 5.2.9 The measurement method and measurement speed of the downhole instrument shall be carried out according to the measurement speed specified in its operating procedures for lifting measurement, lowering measurement or fixed-point measurement. When multiple instruments are used for measurement, the speed of the instrument with the lowest measurement speed shall be used for measurement, and the provisions of the SY/T5132 general rules shall be met. 5.2.10 The lifting and lowering speed of the downhole instrument shall be carried out in accordance with the provisions of SY/T5634. When entering the tubing trumpet or approaching the bottom of the well, the speed should be less than 600m/h.

5.3 Instrument operation
5.3.1 Operate various instruments and equipment according to their respective operating procedures, and calibrate and calibrate according to the calibration and calibration procedures. 5.3.2 Logging data acquisition process. The operating engineer shall control and maintain the consistency of the real-time logging (paper media, film, magnetic media recording) logging (data) data. The quality of logging data shall be implemented in accordance with the quality of single-item logging and original data specified in SY/T5132. 5.4 Data acquisition
5.4.1 The time for the instrument to remain stationary in the open hole shall not exceed 3 minutes (except for item 1 with requirements for residence time) to prevent the instrument from getting stuck and the cable from being adsorbed: If the instrument encounters obstruction or getting stuck, it shall be handled in accordance with the special situation processing specified in SY/5634. 5.4.2 The casing logging depth shall be calibrated to the same depth as the open hole logging line. The verification method is to compare the natural gamma curve with the casing collar.
5.4.3According to the requirements of the survey and notification form, collect the survey data. Obtain all (data) materials in full and accurately, and collect data in accordance with the provisions of SY/T6413.
5.5 Drawing format
The format and requirements of the drawing shall be in accordance with the basic format specified in SY/T5633, and all data shall be complete and accurate. Except for the handwritten signature, all other items and contents shall be printed by computer. +3 The distance between the "zero mark" of the cable depth and the nearest special magnetic mark is 500m. The distance between the "cable length" cable head and the nearest depth magnetic mark should be less than 25m, with an allowable error of ±0.1m. It should be inspected according to the calibration regulations of the logging cable depth mark in SY/T6251.
