Application of high-pressure cleaning machine in oil well plugging removal
1. High-pressure rotating water jet formation treatment technology can produce three physical effects: low-frequency rotating hydraulic pulse waves, high-frequency oscillating cavitation jet shock waves, and cavitation noise (ultrasonic waves) during underground operations. The treatment effect is far better than that of a single physical effect.
2. Good selectivity, strong adaptability, and easy to combine with other treatment methods.
3. The high-pressure rotating water jet blockage removal process has the characteristics of concentrated energy and large processing depth, and the depth can reach more than 600mm.
4. The jet pressure, treatment section, time and rotation speed can be selected according to the specific blockage type and severity.
5. The high-pressure cleaning machine is simple to operate, low in cost, and has significant effect in removing blockage and increasing production.
Construction equipment and requirements for high-pressure cleaning machines in oil well plugging applications
1. Construction equipment: 1 high-pressure cleaning machine, two 400-type cement trucks, and two 15m³ water tank trucks.
2. The construction well should be equipped with a self-sealing device at the wellhead and a return water pipeline connected to the return pool.
3. The ground manifold must be equipped with high-pressure elbows, high-pressure hoses, tees, etc. that are matched with the 4OO cement truck, and must be cleaned to ensure good connection sealing.
4. Depending on the depth of the oil layer and the degree of blockage, the working pressure of the high-pressure cleaning machine is 150-300bar, and the flow rate is about 400L/min.
5. The working medium needs to be clean water. An appropriate amount of anti-swelling agent, deblocking agent, clay stabilizer and other additives can be added according to the physical properties of the formation and clogging conditions to ensure that the working fluid is compatible with the formation rocks and fluids and ensures the deblocking effect.
Therefore, the use of high-pressure cleaning equipment to support and improve oilfield injection technology and the selection of practical and high-quality water well plugging removal measures are of great significance to stable oilfield production and reducing costs.
A large number of cases have proven that this cleaning technology is very complete, confirming that the high-pressure cleaning machine has very good economic and social benefits, thus ensuring the normal production of oil and water wells.
