摘要

通常情况下，页岩气井需要使用大量压裂液，但返排效率较低。由于页岩中压裂液的分布特征复杂，需要进一步评价。本文以龙马溪页岩为研究对象，包括基质岩心、天然裂缝岩心和含支撑剂人工裂缝岩心。对上述三种岩心在压裂液不同程度的吸胀和滞留状态下进行了应力敏感性实验。结果表明:当水相保留度为0 ~ 0.78孔体积时

Stress sensitivity of multiscale pore structure of shale gas reservoir under fracturing fluid imbibition

: Generally, huge amounts of fracturing ﬂuid are used in a shale gas well but the ﬂowback efﬁciency is low. Since the distribution characteristics of imbibed fracturing ﬂuid in shale are complex, they need further evaluation. This paper takes the Longmaxi Shale as the research object, including matrix cores, natural fracture cores and cores of artiﬁcial fracture with proppant. Stress sensitivity experiments are carried out on the above three kinds of cores under different degrees of imbibition and retention state of fracturing ﬂuid. The results show that when the degree of aqueous phase retention is 0-0.78 pore volume

期刊介绍： Capillarity publishes high-quality original research articles and current reviews on fundamental scientific principles and innovations of capillarity in physics, chemistry, biology, environmental science and related emerging fields. All advances in theoretical, numerical and experimental approaches to capillarity in capillary tube and interface dominated structure and system area are welcome. The following topics are within (but not limited to) the scope of capillarity: i) Capillary-driven phenomenon in natural/artificial tubes, porous and nanoporous materials ii) Fundamental mechanisms of capillarity aided by theory and experiments iii) Spontaneous imbibition, adsorption, wicking and related applications of capillarity in hydrocarbon production, chemical process and biological sciences iv) Static and dynamic interfacial processes, surfactants, wettability, film and colloids v) New approaches and technologies on capillarity Capillarity is a quarterly open access journal and free to read for all. The journal provides a communicate platform for researchers who are interested in all fields of capillary phenomenon.
