5.3.4 Pull out the film loader plug. If it cannot be pressed back, it means there is no film in the film loader. 5.3.5 Check the bottom of button A. If you see a red ring or red dot, it means there is no film. You should reload the film according to the previous steps. 5.4 Timing, starting and downhole measurement
5.4.1 Connect the various components of the card machine in the order of Figure 6. 5.4.2 When completed, the start time should be selected according to the regional correction speed and well depth. 5.4.2.1 Timing and starting of mechanical timer: Press down the lever and rotate it in the direction of the arrow. You can observe the set time and the movement of the clothes from the observation window 11, and record the time at the same time. 5.4.2.2 Timing and starting of electric timer: There are two time buttons on the surface of the electric timer, one of which is marked with 1, 2, 9 numbers and the other is marked with 10, 20, ..., 90 numbers, which represent minutes. Select the time and press the start button: the LED starts to flash, the timer starts to work, and starts to record the time. 5.4.2.3 Start the motion sensor: After connecting the instrument, turn the knob switch from "off" to "on" and start recording the time. 5.4.2.4 Start the non-magnetic sensor: Connect the instrument according to the sequence in Figure 6, the indicator light flashes, and the time starts to be recorded. 5.4.3 Install the instrument into the protection tube, connect the protection tube and the extension rod or directional rod. 5.4.4 Use a steel wire to send the instrument from the pipe string to the predetermined measurement position or drop it from the pipe to the predetermined measurement position. The drill can be moved for 1 minute before the scheduled time. When using a mechanical timer or an electric timer, the drill tool should be stopped 1 minute before the scheduled time arrives, and photos should be taken after the time is reached: when using a motion sensor, it should be stopped for 1 minute or 2.5 minutes and then photos should be taken; when using a non-magnetic sensor, it should be stopped for 1 minute or 2 minutes and then photos should be taken.
5.4.5 After the instrument takes photos, the drill tool can be moved. Pull out the instrument. 5.5 Film development

5.5.4 Gently wash the film, temperature 20-27℃: develop for 4 minutes; when the temperature increases by 3℃, the developing time is shortened by 30s accordingly: when the temperature decreases by 3℃, the developing time is extended by 30s accordingly.5.5.5 Open the developing tank. Take out the film, rinse with water for 30s, and let it dry for 1.5.5.6 Use the two angle measuring devices in the measuring unit alternately. 5.6 Reading the film
ZB E13 007-90
5.6.1 Reading 0°～10 and 0°～20 films can be done with the help of a film reader (see Figure 10). Put the film reader on the film, the center point of the film reader is aligned with the film, the normal line on the film reader passes through the center of "+", at this time the normal line refers to the compass scale as the position angle, the center circle where the center of "+\" is located represents the well inclination angle, and the thick line on the film represents the surface. Figure 10 Film reader
5.6.2 Reading 0～90 film, the inclination angle is read from the intersection of the horizontal line and the scale. The angle of force is determined by the intersection of the vertical line and the compass scale. A short thick line on the film indicates a surface. The scale of the film reader is used to read the film. 5.6.3 When reading the film, the inclination angle is accurate to 0.25°, and the azimuth angle is accurate to 16°. Maintenance and calibration
6.1 Protective tube: After the instrument is taken out of the mountain, it must be rinsed with clean water and wiped clean with cotton yarn. If the instrument is not used for more than half a year, all threads must be brushed clean, grease must be applied, and a protective cap must be put on. It should be placed in a ventilated place indoors. 6.2 The timer should be maintained and calibrated once a year. 6.3 The battery must be removed after the instrument is used up.
6.4 Angle measuring device: It is strictly forbidden to touch the lens with hands or coarse cloth. The lens should be gently wiped clean with lens paper: Put on the protective cap, 6.5 Camera: The contact plate between the camera and the battery must be kept clean. The bulb must be replaced when it is exposed for more than 100 times. The lamp bowl should be gently wiped clean with lens paper or absorbent cotton, and the protective cap should be put on. 6.6 The protective tube O-ring and quick-correction rod should be inspected and replaced. 6.7 After the instrument is used up, each part should be disassembled, covered with a protective cap, and placed in the instrument box. 6.8 The measuring film and the most photographic solution should be stored at low temperature and away from light.
