The Second Sidetrack Well in Puguang Gas Field Was Successfully Put Into Production

Recently, the Puguang 103-1 sidetracking well in the Puguang Gas Field was successfully put into production, with a daily gas production of 240,000 cubic meters. This is the second sidetracking well put into production in the gas field.
Wu Xiaolei, deputy director of the gas production plant of the Puguang gas field, introduced that the Puguang 103-1 well had previously been shut down due to severe flooding. This resulted in the reservoirs of the Feixianguan Formation's Fei 3 and Fei 2 members being rich in reserves. "Realization". In order to tap the remaining potential of the reservoir, after conducting feasibility studies, technical personnel decided to deploy and implement the Puguang 103-1 lateral well based on the original well trajectory and supporting facilities of the Puguang 103-1 Well.
Specifically, the technicians formulated the technical method of "nitrogen injection-discharging and spraying-liquid drainage-pressurization-production". Wu Xiaolei said that technicians injected nitrogen into the wellbore and used nitrogen pressure to "push" the liquid in the wellbore underground. At the same time, they used nitrogen and formation energy to bring the liquid out of the wellbore during the blowout, successfully establishing a gas flow channel between the wellbore and the formation. , helping the well to be successfully put into production.
Wu Xiaolei introduced that sidetracking wells have low cost and short production production cycle, which is an effective way to improve the utilization of reserves. The Puguang 203-1 side drilling well, which was successfully put into production previously, has produced a cumulative gas production of 42 million cubic meters.
The successful commissioning of two sidetrack wells has accumulated experience for tapping the potential of water-intruded areas in the Puguang Gas Field. Next, the Puguang Gas Field will dynamically monitor the water invasion and production dynamics of the Puguang 106-2 Well. It plans to deploy the Puguang 106-2 sidetracking well after the well stops blowing out to help the Puguang Gas Field achieve high and stable production.
