WELL COMPLETION TECHNOLOGY ASSOCIATE WITH OVER-HIGH PRESSURE PERFORATION AND OIL WELL STIMULATION

Well completion technology associate with over-high pressure perforation and oil well stimulation is a new technology developing in abroad. The basic theory and the status of the technology are narrated. The process of the operation is introduced. The over-high pressure perforation technology can associate with acidizing or fracturing, which can be used in carbonate reservoir and low pressure and low permeability pools. The technology can reduce operation fare and improve productivity index. The over-high pressure perforation technology also can associate with sand control technology, which can be used in unconsolidated sandstone reservoir. This technology can reduce pollution and improve sand control effects. From the pressure buildup curve of 16 wells who used over-high pressure, the skin factor of 14 wells is negative.
