| 1 | 静态条件下碳酸盐岩三维孔隙网络的溶蚀改造及其对孔隙结构的影响显示文摘为了确定溶蚀对碳酸盐岩孔隙结构的影响,保持pH值和HCl溶液浓度等参数不变,使用泥质灰岩和颗粒灰岩作为研究样品在不同温度下进行了溶蚀实验、X射线微型CT成像、岩石薄片分析实验。研究确定了碳酸盐岩溶蚀释放的Ca^(2+)浓度与时间的关系;溶蚀前后的孔径分布表明温度和孔径变化之间没有相关性,颗粒灰岩中的孔径变化更显著,说明孔径变化主要受岩石本身的物性(初始孔隙度和渗透率)和不稳定矿物的丰度(与晶体形状、大小和矿物类型有关)控制。2种碳酸盐岩在不同温度下的孔喉半径变化量非常小,为0.003~0.040 mm,增加倍数为1.3~3.5,平均为1.7;孔喉长度变化量为0.05~0.35 mm。孔喉半径、长度和连通性的微小变化对渗透率也有很大影响,渗透率变化量高达1 000×10^(-3)μm^2。 | ANDRIAMIHAJA Spariharijaona PADMANABHAN Eswaran BEN-AWUAH Joel SOKKALINGAM Rajalingam | 2019 | 石油勘探与开发2019,46,2: | 8 |
| 2 | Neuroendocrine carcinoma of the ampulla of Vater:a clinicopathologic evaluation显示文摘BACKGROUND:Only 105 cases of neuroendocrine tumor(NET)of the ampulla of Vater have been described, mostly as single case reports.The incidence of NET is rising.The changes in incidence may result from changes in detection.This study was to determine the relative incidence and clinicopathological characteristics of high- grade neuroendocrine carcinoma(small cell carcinoma and large cell carcinoma)of the ampulla of Vater at a single institution. METHODS:Sections from paraffin blocks of tumors of the ampulla of Vater taken from 45 patients who underwent Whipple's procedure and 6 patients who underwent palliative bypass between September 2003 and January 2007 were subjected to immunohistochemical analysis.The clinical and pathological data from 5 patients diagnosed with NET of the ampulla of Vater were analyzed. RESULTS:The patients were 3 men and 2 women,ranging in age from 39 to 47 years(mean 44 years).Operative procedures included Whipple's procedure in 4 patients and palliative bypass in 1 patient.Histopathological examination revealed large-cell neuroendocrine carcinoma in 2 patients,small cell carcinoma in 2,and carcinoid in 1.Three patients with high-grade neuroendocrine carcinoma who had undergone Whipple's procedure died at postoperatively 7,11,and 13 months.The patient who had undergone palliative triple bypass died 3 months after surgery.CONCLUSIONS:The relative incidence of high-grade neuroendocrine carcinomas of the ampulla of Vater is higher than that generally expected.The tumors behave aggressively and have a dismal prognosis despite aggressive treatment. | Eswaran Selvakumar Shanmugasundaram Rajendran Tirupporur Govindaswamy Balachandar Devy Gounder Kannan Satyanesan Jeswanth Palaniappan Ravichandran Rajagopal Surendran | 2008 | Hepatobiliary & Pancreatic Diseases International2008,7,4: | 7 |
| 3 | 生物扰动对砂岩储集层物性的影响--以马来西亚沙捞越巴拉姆三角洲为例显示文摘以马来西亚沙捞越巴拉姆三角洲为研究对象,进行取样岩心和薄片分析,结合EDX(能量色散X射线)、FESEM(场发射扫描电镜)、压汞测孔隙度和点状渗透率测量等方法评估生物扰动对储集层孔隙度和渗透率的影响。岩心取自巴拉姆三角洲W-1井和W-6井,分析结果显示,W-1井样品主要发育双杯迹潜穴(Diplocraterion),为强烈—剧烈生物扰动,可见沉积物充填,沉积物充填活动将宿主沉积物中的细粒物质(黏土和有机物)混入潜穴充填物和潜穴衬里,降低沉积物的均质性和分选性,导致潜穴中局部区域孔隙度和渗透率降低;W-6井样品主要发育蛇形迹潜穴(Ophiomorpha),为强烈—剧烈生物扰动,黏土和泥质被清除出潜穴充填物和宿主沉积物,聚集于潜穴衬里,潜穴生物的沉积物清除活动导致潜穴内部沉积充填物的分选性变好、孔隙度和渗透率升高。生物扰动对储集层孔隙度和渗透率的影响由潜穴及其充填物和潜穴活动的类型决定。 | Ben-Awuah Joel Padmanabhan Eswaran | 2015 | 石油勘探与开发2015,42,2: | 7 |
| 4 | Long-term outcome of gastric access loop in hepaticojejunostomy显示文摘BACKGROUND:The incidence of hepaticojejunostomy stricture is 4%-10% in experienced centres. Many access loops have been designed and used to facilitate endoscopic intervention for this complication of hepaticojejunostomy. In this study, we investigated the effectiveness and safety of gastric access loop. METHODS:A retrospective analysis was conducted on 13 patients who had undergone hepaticojejunostomy with gastric access loop between June 1999 and September 2003. Eleven patients were followed up for a mean period of 51 months (range 20-81 months). Two patients were lost to follow up. RESULTS:On follow-up, 8 patients had patent jejuno- gastrostomy (end to side anastomosis between Roux loop of jejunum and stomach) and hepaticojejunostomy. Three patients developed stricture of jejunogastrostomy at 41 months, 63 months and 81 months of follow-up. Among these 3 patients, one also had hepaticojejunostomy stricture. In the patient with hepaticojejunostomy stricture, dilatation of jejunogastrostomy stricture was attempted but failed. None of the patients had any evidence of bile gastritis/cholangitis. There was no procedure related morbidity/mortality. CONCLUSIONS:Further studies involving large numbers of patients are required before wide application of gastric access loop in hepaticojejunostomy though it is a safer option than percutaneous transhepatic manipulations or revision surgery. | Eswaran Selvakumar Shanmugasundaram Rajendran Tirupporur G.

| 6 | 马来西亚沙捞越盆地东北部第三系石英表面形态特征--对古沉积环境与储集层质量的指示意义显示文摘基于马来西亚沙捞越(Sarawak)盆地Belait组和Lambir组第三系露头样品,分析其石英表面形态,揭示其颗粒表面结构缺陷(源自风化作用和成岩作用)、古沉积环境以及储集层质量之间的相关关系。研究利用岩石薄片进行矿物识别,并观察粒径和结构;利用扫描电镜对样品的表面形态进行表征,以展现石英颗粒表面结构的变化。Belait组砾岩的扫描电镜图像表明其以自形石英晶体为主,常见机械风化缺陷,例如线性断口、贝壳状断口以及擦痕;而Lambir组砂岩中却常见化学风化特征,例如化学蚀痕、蚀坑、溶解坑以及刻痕。基于岩石学、扫描电镜以及CT扫描图像分析的储集层质量评价结果表明,研究区Belait组为高能海岸沉积,潮控特征明显,Lambir组为浅海—三角洲沉积,浪控特征明显;Belait组和Lambir组的储集层质量较差,但Belait组的孔隙度略高于Lambir组。 | Abdullah Musa Ali Eswaran Padmanabhan | 2014 | 石油勘探与开发2014,41,6: | 4 |
