Oil production plant three hydraulic jet pump drainage gas was successful
October 04, 2024
Oil production plant three grams grams 00 wells after the hydraulic jet pump drainage measures, the outer exhaust gas flame 4 - 5 meters, Nissan 20,000 cubic meters of natural gas, which marks the first oil company in the third oil production plant hydraulic jet pump liquid production process Success.
Well K 006 is located in Upper Wuerhe Formation of the South Permian in the five districts of Karamay Oilfield. After fracturing in September 2005, the well was shut down due to the failure of the fracturing fluid to be discharged and no gas output.
June 8 this year, the plant geology, technology and other departments, for the first time on the 006 wells used hydraulic jet pump liquid discharge gas new technology, on the 24th began to use ground pump injection of fluid for wellbore drainage.
Hydraulic jet pump is based on the principle of jet work, that high-pressure fluid (power fluid) through a small diameter end face, the speed increases, resulting in reduced pressure, resulting in the end face around the formation of "negative pressure" zone, resulting in suction Role, the inhalation of the formation fluid and power fluid through the throat mix, and then spread through the diffuser, and gradually restore the pressure energy, the pressure to complete the mixed liquid delivery or lifting, so that the mixed liquid along the oil casing annular space raised to the ground .
After more than 20 days of drainage, the total amount of fluid in well 006 was exhausted to reach 136 cubic meters. This shows that the wellbore effusion has been improved and the gas well productivity has been restored.
July 14, the plant technicians to take measures to nitrogen gas well discharge wellbore liquid column, to induce gas production.
After three hours of nitrogen gas lift, with a needle valve to open well drainage, discharge a lot of oil, gas and water. The pressure of Well K 006 recovered to the pressure before shut-in, Nissan 20,000 cubic meters of natural gas.
The success of using the jet pump for liquid production and gas recovery in Well K 006 will provide a basis for increasing the gas quantity of the 75 treatment plant of the plant and improving the adaptability of the treatment process so as to deepen the understanding of the reservoir.
