  Chinese oil network news at the end of August, the reporter was informed that the western drilling logging company C3515 team lasted 14 days, the successful completion of horizontal well MaHW1283 30 perforation bridge plug joint operation, to create the domestic horizontal well multi-stage perforation new record.

  Well MaHW1283 is located in Mahu 131 well area, depth of 5356 meters, the longest pumping wells 2300 meters, operational pressure up to 60 MPa, the maximum deviation of 95 degrees, there is obvious upward in the horizontal section brings great difficulty to the pumping perforation. At the beginning of the design, the perforation level of the whole well was scheduled to be 23. In the following process, the production capacity was optimized and the production was improved, and the operation was adjusted to 30 levels, so the operation difficulty was increased.

  In order to make the downhole tools pump not automatically slide, the perforation expert group optimized the perforation scheme and monitored the whole process. In the upturned well section, a gun string with a 0.6 liter / second displacement is pushed down, and the cable is tensioned at the same time, thus solving the technical problem of the sliding of the gun string in the upturned well section.

  In the course of operation, due to the long operation time of the single well, the maintenance of the equipment should be carried out on the spot. The operation team starts with standardized management of safety production in the team, and strictly implements the management of post territory. In order to improve the operation time, each position will work overtime, and replace the choke pipe, seals and sealing grease in order to ensure the safety and reliability of the equipment.

  Whenever the end of fracturing, perforation members in accordance with the requirements of 8 individuals, 4 operations start at the same time, the orderly spread bridge plug, perforating gun, firing device, horse leading process, won time for horizontal speed.
