摘要
水力喷砂射孔与压裂联作是集射孔、压裂一体化的新型增产措施,一趟管柱多段压裂,提高了施工的效率和安全性,减少施工风险,降低了施工成本,是对低渗透油层改造的重要手段。目前,已在长庆油田多个区块展开试验,该技术在江平12-21井的试用中,不仅施工过程进行的很顺利,而且测试、求产后与同层的常规定向井相比增产效果十分显著。此次试验,对水平井的大规模开发具有指导意义,它作为一种新型的工艺,必将成为长庆油田开发中很重要的增产、增注措施之一。
The combined technology of hydraulic jetting oriented perforating and fracturing is a new measure to increase production. Multi-stage fracturing not only can improve the efficiency and safety, but also can reduce the risk and costs, it is a significant method to improve low permeability reservoir. Currently, this technology is tested in many zones in Changqing oilfield. During application of the technology in 12-21 well of Jangping oilfield, the process of construction is going well, while the result of experiment after production is better than that of conventional directional well in the same layer, it is very significant to increase the yield. This experiment is a great significance to large-scale development of horizontal wells. As a new technology, it will become a significant measure to increase production and increase injection.
