Before opening, check the distance from the locator recording point to the perforator hole, the gun loading length and the number of bullets: the results should be consistent with the construction single phase 3.8 When using a gun and perforator, you should first use a rod with the same outer diameter as the perforator to clear the well. Only after confirming that the perforator is unblocked can you lower the perforator.
3.9 Requirements for opening the Christmas tree gate and lowering the cable. 3.9.1 Install the blowout preventer properly: collect the excess cable on the dry roller. After the depth meter is zeroed, you can open the pressure relief valve of the hand pump. At this time, all personnel should leave the cable to prevent the cable from bouncing and injuring people. 3.9.2 Open the wax cleaning gate of the Christmas tree to allow the oil pipe pressure to slowly enter the blowout preventer. There should be no leakage at each connection. And test the pressure of the blowout preventer at the plate mouth
3.9.3 When the pressure in the blowout preventer box reaches equilibrium with the oil indicator, open the wax cleaning gate completely. Then open the fall arrester flap and slowly lower the cable. At the same time, remove mud, sand and other debris on the cable and check the magnetic mark for calibration alarm. 3.9.4 While performing the operation in 3.9.3: the grease pump should be stopped to inject grease into the blowout prevention box. The standard grease pump pressure should be 5MPa higher than the oil pressure.
395 For wells with zero oil pressure, the blowout prevention system test and pressure test should be carried out according to the highest possible pressure resistance.
3,9.6 The cable lowering speed should be uniform, and the dispersion speed should not exceed 4000m/h. Grease should be injected into the cable at any time to lubricate it. 3.9.7
After the blowout preventer is lowered or during the pressure test, if any seepage is found, the gate should be closed immediately and the bed pressure should be released. 39.8 After the blowout preventer is lowered, if the cable does not move downward after the pressure valve is called, the suspension should be increased as necessary.

39.9 When lowering the cable: use ground instruments to monitor whether the movement of the non-instrument is normal. 3.9.10 When the instrument is lowered to the tubing shoe, the measurement should be recorded and interpreted to show whether the curve reflects the tubing shoe and whether its depth is consistent with the notification sheet. After confirmation, the operation can continue. 13.10 Requirements for depth measurement, ignition and cable lifting 3.101 When the cable is lowered to the vicinity of the short casing, the depth measurement can be carried out to find the standard coupling determined by the construction calculation sheet. 3.10.2 The depth record curve must be complete and clear. 3.10.3 Before each blast is fired, three people must check the standard coupling, tachometer reading, lifting (or lowering) number and gun length. After confirmation, the captain of the small-scale shooting team will issue the ignition order: 3.4 Before ignition, the gate of the Christmas tree should be closed. When operating without a packer, the gate of the Christmas tree casing should also be closed to prevent the high oil and gas flow from gushing out and lifting the cable, causing a jam. 3.10.5 After ignition, the magnetic positioning curve of the perforation section should be measured as a basis for checking the perforation position and quality. During ignition, pay close attention to the changes in external pressure and external quantity. If the pressure exceeds the pressure during ignition, the cable should be lifted to the opening under the condition that the hanging weight of the instrument is allowed. Otherwise, the cable cannot be lifted, and corresponding measures should be taken (such as releasing pressure or pressing). The cable can only be lifted when it is confirmed that the cable will not be sprayed out. 3.10.7 The lifting speed of the cable cannot exceed 4000m/H: when lifting to the vicinity of the opening, the speed should be reduced, and the gun body should enter the shield of the pipe before lifting at normal speed.
3.10.8 When lifting the cable, lubricate the cable with grease at any time. The winch must coil the cable neatly and spray lubricating oil. 3.10.9 When the cable is fully lifted to about 11,100m, the winch must slow down and check the readings of each tachometer again: and open the alarm for monitoring. At the same time, the lifting worker drops the anti-drop device flap and listens to the sound inside at the parallel port. The winch should pay attention to the changes in cable tension and obey the instructions of the non-opening and instrument operators, and be ready to stop at any time. 3.10.10 After the lowering instrument and the collected perforator are completely entered into the blowout preventer, immediately close the main door of the oil production tree, and then drain the air and liquid in the blowout preventer through the venting pipeline connected to the production door, disassemble the lowering instrument and perforator, and check the emissivity of the perforator.
3ⅡExcept for the factory to avoid the lowering instrument from pulling the cable manually due to the blowout preventer box top causing the cable to be broken, no one shall stay near the running cable during the entire construction process, and it is even more indecent to cross the cable at will. 3.12 After the completion of the construction, all tools and equipment should be sorted and cleaned, and placed in the specified position. The construction site should be completed. 3.13 The equipment should be maintained according to the regulations, and the wear and tear should be checked and replaced in time. 4 Other technical safety regulations for tubing perforation are the same as those for general perforation.
