The reserves and yield increasing measures in unconventional hydrocarbon reservoirs are mainly achieved by the large displacement, large liquid volume and large sand volume multilevel staged fracture reforming technology of horizontal well. The conven-tional single fracturing unit and its fluid supply and distribution mode cannot satisfy the fracture operation requirement at all. Therefore, in optimizing the matching of multiple frae units, two sand mixing trucks are adopted to carry out online operation at the same time. The data collection and the real-time operation curve are integrated to achieve the centralized control, data collection and remote transmis-sion monitoring of multiple units. Meanwhile, the technology of muhilevel fluid supply and continuous mixing of different fracture sys- tems is improved to achieve the unconventional fracture operation of horizontal well with continuous seamless switching of multiple frac-ture fluid systems. The total completed preparation of fracture fluid is 23 000 m^3 in fracture operation in 15 sections of Well HF1 of Biye. The maximum fluid preparation is 3 705 m^3/d. The actual fluid volume into hole is 22 129 m^3. The maximum displacement is 14. 7 m^3/min. The maximum pressure is 68 MPa. The sand adding volume is 799.6 t. The operating displacement of a single sand mix-ing truck is 5 - 8 m^3/min. All the technological parameters are in agreement with the design requirement of operation.%非常规油气储层增储增产主要是通过大排量、大液量和大砂量的水平井多级分段压裂改造技术来实现的，常规单套压裂机组及供配液方式已远远不能满足其压裂施工工艺要求。为此，在优化多套压裂机组配套时，采用2套混砂车同时在线施工并整合数据采集及实时施工曲线，实现多机组集中控制、数据采集和远传监控，同时完善多级供液和不同压裂液体系的连续混配工艺技术，实现了多种压裂液体系连续无缝切换的非常规水平井压裂施工。在泌页HF1井15段压裂施工中，累计完成压裂液配制23000m^3，最高配液量3705m^3。／d，实际入井液量22129m^3，最高排量14．7m^3／min，最高压力68MPa，加砂量799．6t，单台混砂车施工排量5～8m^3／min，各项技术参数符合施工设计要求。
