Adding new technology to hydraulic oscillators for petrochemical machinery
On September 25th, the independently developed 4-3/4 inch hydraulic oscillator by Petrochemical Machinery was tested and successfully lowered into the well at the wellhead of Shengli Oilfield, and all performance indicators met the on-site construction requirements. This marks the further expansion of the company's hydraulic oscillator into the Shandong market and the enrichment of its product size series.
Hydraulic oscillators are mainly used for directional drilling in horizontal wells, which can effectively improve the friction of drilling tools, reduce sliding pressure, significantly increase drilling speed, save drilling time, extend the mission life of drill bits, and assist in the efficient and safe development of oil and gas resources.
Previously, petrochemical machinery made significant breakthroughs in related core technologies, and developed hydraulic oscillators of various sizes such as 2-7/8, 6-1/2, 6-3/4, and 8 inches, which were successfully applied in work areas such as Sichuan Chongqing and northern Shaanxi, with a focus on solving the pressure problem. The well locations involved conventional oil and gas horizontal wells and Fuling shale gas development wells.
In the Sichuan Chongqing market, petrochemical machinery's 6-3/4 inch hydraulic oscillators have been used in 5 wells on the Jiaoye platform for a total of 1500 hours without faults, and the excellent performance of the tools has been recognized by customers; The 2-7/8-inch hydraulic oscillator was inserted twice during the continuous tubing operation in a well in the Fuling work area, and has been used for a total of 52 hours, becoming a successful symbol of the first domestically produced application of small-sized hydraulic oscillators in the same series in the Fuling work area, breaking the market monopoly of similar hydraulic oscillators abroad; In response to the high friction between the drilling tool and the wellbore at the bottom of a certain well in the Jiangdong block of the Fuling work area, as well as the directional support pressure problem of a long horizontal section, a targeted hydraulic oscillator has been developed to achieve three horizontal sections and one drilling trip, helping to complete the horizontal section construction 5 days ahead of schedule.
In a certain well in the Yanbei block of the Shaanbei work area, a targeted hydraulic oscillator was provided to complete the inclination section operation, which effectively solved the problem of directional support pressure. A single well operation lasted for 135 hours, assisting in drilling until the completion of the third drilling. Compared with the previous drilling, the sliding mechanical drilling speed increased by 44%, and the comprehensive mechanical drilling speed increased by 17%.
Petrochemical machinery hydraulic oscillators have continuously accumulated good reputation and market service experience. In areas such as Sichuan and Chongqing, a dedicated hydraulic oscillator service department has been established to strengthen well research and follow-up services, focusing on solving on-site engineering problems and continuously optimizing and improving hydraulic oscillator products and technologies.
