20)1- 06 - 01 Implementation
The shock absorber is not deformed:
dThe head is not damaged or deformed:
The rotating cabinet is flexible:
SY/T64982000
The protection is simple and the time circle must be new2.1.7 Inspection of ground equipment:
) Connect the ground system and control pipe correctly as required:b) Connect the 220VA110V transformer, and its output voltage should be 110V10Vc) After power on, the input and output of the instrument terminal are positive.2.1.8 Salvage measures:
The salvage rod is not damaged, deformed, and the surface:
6 Salvage hand springs are flexible:
) Salvage measures are not matched with the salvage head.
2.2 Construction Preparation and inspection before use
Connect to an AC power supply with a voltage of 210-230V and a frequency of 50-60H. 2.2.1
Inspect the 220VA10V set of pressure type. The total output voltage should be 110V10V. Check the probe and connect the specified 2.1.2 heat conduction
Inspect the ground equipment: Heat the equipment according to the provisions of 217. Make sure that the drilling tool is fully charged and the water hole is smooth. 3 Parameter setting and ground assembly
3.1 Zero setting
3.1.1 Determine the number of batteries. When the measurement time is within 4h, 4 C batteries can be selected: When the measurement time exceeds 4h, 8 \C\ batteries need to be selected.
3.1.2 Connection between the battery and the probe #:
a) The tightening torque of the battery cylinder and the probe is 40Nmt6) The tightening force of the battery top bolt is 1.25Nm: tighten the anti-loosening nut.
3.1.3 Connect the probe to the ground equipment
3.1.4 The setting of the probe delay time is based on the flow drop of 250m/m in the vertical well. The other parameters are set correctly according to the actual situation on site
3.2 Ground installation
3.2.1 Clean the instrument, protect the barrel thread, and apply frequency grease. 3.2.2 Install the \0# shape seal
3.2.3 Install the straightening rod.
3.2.4 Before installing the probe into the protective cylinder: At the same time as the reset switch of the technical control pipe Start the ground stopwatch at the same time. After the probe indicator light flashes three times, close the switch cover. 3.2.5 Install the downhole instrument assembly into the protective sleeve and tighten all the connecting threads. 3.2.6 Lift the downhole assembly steadily to the drilling platform. 4. Measurement and data recovery. 4.1 Data measurement. 4.1.1 The instrument is put into the drill pipe. In the case of small well inclination, the instrument falls freely. In the case of large well inclination, it is difficult to lower the instrument to the bottom of the well. The method of intermittently disconnecting the pump with a small displacement can be used for delivery. The sum of the pressure of the hydraulic fluid column and the pressure of the station tool is not more than 1G0MPa. During the lowering of the instrument, in order to prevent the drill from getting stuck, the drill tool needs to be moved up and down. 4.1.2 According to the set selection time, after the instrument is still, record the measurement speed and measurement time of the turning point. 41.3 The interval between measuring points is stored as a column length. At the same time, record the time, column number and obstacle of each point. 4.1.4 It is forbidden to use the turntable to unhook during the drilling process. 4.15 After the measurement is completed, the receiver can be broadcast. 4.1.6 Arrange the ground records of the secondary measurement.
4-2 Data recovery
4.2.1 Connect the probe and ground equipment
4.2.2 Connect the terminal to the interface of the probe and play back and print the measured data through the terminal printer. 4.2.3 The probe data at the same time shall correspond to the ground depth measurement data. 4.2.4 The complete measurement results shall be recorded in the dose record sheet. The format of the dose record sheet shall refer to Appendix B (Standard Appendix) and Appendix C (Standard Appendix).
Recovery and maintenance of the collection base
Please clean and dismantle the downhole instrument,
Check the sound damage of the instrument and the sensitivity of the yellow system. 52
Apply grease to the thread and put on the protective cap
Clean the ground equipment and install it in the protection range. 5.4
The probe must be calibrated every six months. If the data is found to be wrong during measurement and inspection, it should be calibrated in time. 5.5
The instrument protection should be stored in a magnetic environment. 5.6
