通过对常规岩心流动仪的技术改造，新组建了一种裂缝岩样应力敏感性及其暂堵评价实验装置，并利用该装置对组合裂缝岩样进行暂堵评价，形成一套裂缝储层保护广谱暂堵型工作液评价新技术，该技术同样可用于深探井广谱型保护油气层钻井完井液研究
Through the technical innovation of the conventional core flow meter, a new experimental device for evaluating the stress sensitivity and temporary plugging of fractured rock samples has been established. With this device, the temporary fracture assessment of the composite fractured rock samples is carried out to form a reservoir of fractured reservoirs Broad-spectrum temporary plugging working fluid evaluation of new technologies, the technology can also be used for deep well exploration broad-spectrum protection of oil and gas well drilling and completion fluid research
