Crack propagation and hydraulic fracturing in different lithologies

We simulated hydraulic fracturing in different lithologic rocks in the horizontal drilling by using the true physical model experiment and large rock specimens, carried out the real-time dynamic monitoring with adding tracer and then did post-fracturing cutting and so on. Based on this monitoring results, we co.pared and assessed the factors affecting expansion in shale, shell limestone, and tight sandstone and the fracture expansion in these rocks. In shale, the reformed reservoir volume is the highest, fracture network is formed in the process of fracturing. In tight sandstone, the fracture surface boundaries are curved, and the fracture surface area acco.nts for 25–50% of the entire specimen. In shell limestone, the co.plexity of the fracture morphology is between shale and tight sandstone, but no fracture network is developed. Brittleness co.trols the fracture surface area. In highly brittle rocks, the fracture surface area is high. Fracture toughness mainly affects the initiation and propagation of cracks. A fracture network is formed only if bedding planes are present and are more weaker than their co.responding matrix. The horizontal in situ deviatoric stress affects the crack propagation direction, and different lithologies have different horizontal in situ deviatoric stress thresholds. Low f luid injection rate facilitates the formation of co.plex cracks, whereas high fluid injection rate favors the development of fractures. Fluid injection weakly co.trols the co.plexity of hydraulic fracturing in low-brittleness rocks, whereas lowvisco.ity fracturing fluids favor the formation of co.plex cracks owing to easy enter microcracks and micro-pore. Displacement has a greater impact on high brittle rocks than low brittle rocks.

Antioxidative Protective Effect of Icariin on the FeSO_4/H_2O_2-damaged Human Sperm Based on co.focal Raman micro-spectrosco.y

引用

Journal of Huazhong University of Science and Technology(Medical Sciences) 2014年第5期34卷 755-760页

Oxidative stress is implicated in male infertility and significantly higher reactive oxygen species are detected in 25% of infertile males. Although different agents of various alternative medicines, including traditional Chinese medicine, have been tried with varying success, evidence remains limited on whether and how much herbs or supplements might help increase the anti-oxidant ability of the sperm. This study examined the anti-oxidative effects of icariin, a flavonoid isolated from Herba Epimedii, on the human sperm. We prepared the FeSO4/H202-damaged human sperms, which were co.cultured with icariin in vitro, and then observed the changes of the sperm by employing Raman mi- cro-spectrosco.y. The results showed that Raman mapping with a 514 nm excitation laser allowed clear differentiation of the nucleus, neck, and, in particular, the mitochondria-rich middle piece of a human sperm cell. The effect oficariin on different organelles of the sperm was quantified by localized spectral Raman signatures obtained within milli-seco.ds, and icariin co.ld keep the ＂Raman fingerprint＂ of the human sperm the same as the co.trol groups, suggesting that icariin co.ld protect the human sperm from being damaged by FeSO4/H202. Icariin may serve as a tonifying and replenishing agent of herbal origin for enhancing reproductive fimctions.
