纤维压裂技术由于其独特的优势,近几年不断涌现出来。其主要材料纤维,目前没有一套系统的性能检测评价方法,为此结合纤维材料实际应用,笔者开展了实验研究。系统考察了纤维自身物化性能,纤维对压裂液携砂以及支撑剂导流性能的影响,提出了压裂用纤维材料的性能评价方法,同时提出了质量损失率不大于2%,静态沉降速度降低率不小于15%,对导流能力影响率不大于10%等相关性能指标,为纤维材料的优选以及标准修订完善提供参考依据。
Due to its unique advantages, fiber fracturing technology has emerged in recent years. The main material of fiber, there is no set of system performance testing evaluation methods, combined with the practical application of fiber materials, the author conducted an experimental study. The physical and chemical properties of the fiber, the influence of the fiber on the sand carried by the fracturing fluid and the conductivity of the proppant were systematically investigated. The performance evaluation method of the fracturing fiber material was put forward. Meanwhile, the mass loss rate was less than 2% and the static sedimentation velocity Reduce rate of not less than 15%, the impact of diversion capacity of not more than 10% and other related performance indicators for the optimization of fiber materials and standards to provide a reference for improvement.
