Abstract Hydraulic sand-fracturing experiments are conducted at different proppant content and fracturing fluid viscosities on samples obtained from the shale reservoirs in the Guanyinqiao Member. The characteristics of the obtained sand-fracturing curve and proppant distribution are investigated. The test results establish that the fracture morphologies and proppant distribution after sand fracturing have significant differences. Although the proppant is favorable for increasing the fracture width, the fracture width does not increase gradually with the increase in proppant content. For both acoustic emission localization and proppant distribution, the sand fracture effect is best at a proppant content of 10%.

砂压裂支撑剂增产效果试验分析

摘要 对观音桥段页岩储集层样品进行了不同支撑剂含量和压裂液粘度的水力压砂压裂试验。对所得砂-压裂曲线特征及支撑剂分布进行了研究。试验结果表明，加砂压裂后的裂缝形态和支撑剂分布具有显着差异。虽然支撑剂有利于增加裂缝宽度，但裂缝宽度不会随着支撑剂含量的增加而逐渐增加。对于声发射定位和支撑剂分布，砂体破裂效果最好在支撑剂含量为 10% 时。
