Acidized fracturing sandstone
- Good results have been achieved in the pressure decline analysis of the acid fracturing well in Tahe Oilfield.
- The pressure decline analysis and evaluating techniques for acid fracturing wells develop quite slowly.
- With the development of acid fracturing technologies, the post-frac diagnostic, evaluation methods and the interpretation models became more important.
- A field test is performed in Well Wen 279 by using a new joint-operational technique of super-overbalance perforating and acid fracturing .
- Vibration blocking removal technologies,acid fracturing technique,steam injection,water injection were generalized successfully in oil recovery process.
