| 1 | 利用测井曲线评价碎屑岩岩石物理参数——以埃及尼罗河三角洲El-Wastani气田上中新统为例显示文摘利用埃及尼罗河三角洲El-Wastani气田10口气井的测井数据,对该气田主要储集层上中新统Qawasim组和Abu Madi组进行岩石物理分析,利用测井参数交会图进行岩性分析,并评估泥质含量、孔隙度、含水饱和度、含油气孔隙体积等参数。分析各井中子孔隙度-密度交会图、中子孔隙度-无铀伽马交会图和岩性-饱和度交会图发现:下Abu Madi组主要为砂岩,偶夹页岩;Qawasim组主要为页岩,偶夹砂岩。利用参数交会图及无铀伽马测井结果,得到有效产层各参数的临界值分别为:泥质含量50%,孔隙度10%,含水饱和度70%。分别绘制了产层有效厚度、平均孔隙度、泥质含量、含水饱和度等参数的等值线图,综合分析发现,研究区Qawasim组和Abu Madi组碎屑岩为优质储集层,天然气有利聚集区呈北西—南东向展布,中部尤为有利。 | Ezz S El-Din Maher A Mesbah Mohamed A Kassab Ibtehal F Mohamed Burns A Cheadle Mostafa A Teama | 2013 | 石油勘探与开发2013，40，4： | 3 |
| 2 | Protective effect of ascorbic acid in experimental gastric cancer: reduction of oxidative stress显示文摘AIM: Oxidative stress participates in the cell carcinogenesis by inducing DNA mutations. Our aim was to assess whether ascorbic acid, an antioxidant, could have a role in preventing ROS (Reactive Oxygen Species) generation in experimental gastric carcinoma in a rat model.METHODS: Experimental gastric cancer was induced in twelve Wistar male rats (weighting 250-350 g) by profound duodeno-gastric reflux throught split gastrojenunostomy. The rats were allocated to the following groups: Group Ⅰ (n=6)was the control; Group Ⅱ (n=6) which was mantained with daily intake of tape water with Vitamin C (30 mg/Kg). After 6 or 12 months, samples of gastric tumor or non tumor mucosa were taken from the anastomosis of both groups.Oxidative stress was measured by superoxide quantification through lucigenin-amplified chemiluminescence base and by staining with Nitrobluetetrazolium. The histopathologic confirmation of adenocarcinoma was made by eosinhemathoxilin method.RESULTS: The intestinal type of gastric adenocarcinoma was microscopically identified in all animals of group Ⅰwhereas only 3 rats of group Ⅱ showed an adenocarcinoma without macroscopic evidence of them. The cancers were located in the anastomosis in all cases. Basal luminescence from tumor gastric tissue generated 38.4±6.8 count per minute/mg/x106 (mean±SD) and 14.9±4.0 count per minute/mg/×106, respectively, in group Ⅰ and Ⅱ animals (P<0.05). The Nitrobluetetrazolium method showed intense staining in tumor tissues but not in non neoplasic mucosa.CONCLUSION: Experimental gastric tumors seem to produce more reactive oxygen species than non neoplasic gastric tissue. The reduction of oxidative stress and gastric tumor incidence in rats were induced by the intake of ascorbic acid. Therefore, it may have a role in the prevention of gastric carcinoma. | Claudia P.M.S.Oliveira Paulo Kassab Fabio P.Lopasso Heraldo P.Souza Mariano Janiszewski Francisco R.M.Laurindo Kioshi Iriya Antonio A.Laudanna | 2003 | World Journal of Gastroenterology2003，9，3： | 2 |
