| 摘 要： | 针对火山岩储层压裂改造过程中裂缝形态复杂的问题,采用较为先进的井下微地震水力裂缝监测技术对压裂裂缝进行了2口井的监测。结果表明,火山岩储层压裂过程中裂缝的扩展规律与砂岩油藏有很大不同,裂缝形态复杂,具有水平缝、多裂缝等特征,而且容易造成缝高延伸过度。因此,在压裂设计中要充分考虑,结合应用缝高控制技术,增加裂缝的长度,提高压裂改造的效果。下一步还需要继续开展火山岩地层压裂裂缝的监测,认识裂缝的延伸和产状,为优化压裂设计和井网部提供指导。

| Abstract: | Aiming at the complex shape of fractures in volcanic reservoir during fracturing,downhole microseismic fracture monitoring technique is used to monitor the fractures in two wells.The results show that the expanding law of the fracture in volcanic reservoir is very different from that in sandstone reservoir during hydraulic fracturing.The shape of the fractures is complex with multi-fracture and horizontal fracture,and the height of the fracture expanded excessively. The design of fracturing should be fully ... |
