摘要
介绍了不动管柱两层及三层压裂工艺原理及优点。该工艺可实现多层压裂及排液一体化,简化了施工,适用于底部有已射开层的选层压裂,确保了井下工具安全可靠;该工艺在CO2压裂井上具有重要意义,可实现一次配液3~5 h完成两层、三层CO2压裂,缩短了施工周期、降低了试油成本。
By introducing technical theory and advantages of two-and three-fracturing layers with fixed string can see that the process achieves integrated operation of multi-fracturing and drainage,simplifies the operation sequences,suits for selected layer fracturing having perforated section at bottom to ensure safe and reliable downhole tools.This process has an important sense in fractured well containing CO_2,can complete two layers,three layers of CO_2 fracture in 3～5 hours by once dosed fluid which Shortens the operation cycle and reduces oil test costs.
