极限生产压差 Extreme Producing Pressure Differential
Research demonstrates that the danger of sand production decreases through controlling the time of pressure release. The critical drawdown pressure increases because of the formation of compaction zone in the fracture creation in screen out fracturing.
研究表明,控制开井降压时间可有效降低出砂危险,另外,脱砂压裂造缝压实区的形成可在一定程度上提高临界生产压差。
