Time: 2009.10
Well: Baolang Oilfield Baobei district B1226
Effect: ① Before and after using MGS-W, the changes of pressure and water injection rate
Before | After |
Pressure (Mpa) | Water injection rate (m3/d) | Pressure (Mpa) | Water injection rate (m3/d) |
Pump pressure | Oil pressure | Casing pressure | 23 | Pump pressure | Oil pressure | Casing pressure | 100 |
32 | 31.8 | 31.5 | 32 | 31.8 | 31.5 |
②Before and after using MGS-W, the curve of the changes of pressure and water injection rate
③ When the well is open , the pressure is controlled at 10Mpa, water injection rate is 30 square, then increase water injection, the injection pressure is same as pre-construction, the daily water injection rate increases from23 to 100 square. To the present the water injection rate is still 30 square, showing superior decompression and Injection- augmentation effect than ordinary acidification in the past, further proof that this technology can be implemented through the construction of this well, can indeed achieve the goal of decompression and injection-augmentation effect.
