| 支撑剂用于压后支撑裂缝，防止人工裂缝完全闭合，改善储层渗流环境，建立储层与井筒间的油气流动通到，对储层改造效果具有至关重要的作用。支撑剂嵌入及破碎是支撑裂缝导流能力下降的主要因素。建立了考虑支撑剂破碎堵塞孔隙吼道的裂缝导流能力计算模型，开展了川南页岩气现场常用70/140目石英砂在龙马溪组露头条件下的支撑剂性能测试，模型计算结果与室内测量结果对比表明计算结果可靠，可为压裂支撑剂优选、支撑剂用量优化、压后支撑裂缝导流能力评价提供技术支撑。 |
| 英文摘要: |
| Proppant is used to proppant fractures after compression, to prevent the complete closure of artificial fractures, to improve the reservoir percolation environment, and to establish the flow of oil and gas between the reservoir and the wellbore.Proppant insertion and fracture are the main factors that decrease the conductivity of proppant fractures.Is established considering proppant crushing blocked pore fracture diverting capacity calculation model of shouted, in the basis of the shale gas field commonly used 70/140 orders under the conditions of quartz sand in the creek, the dragon group outcrop proppant performance tests, the results of laboratory measurement and model calculation results shows that the calculation result is reliable, optimization of fracturing proppant and support agent support fracture diverting capacity evaluation after optimization, the pressure to provide technical support. |
