"组合测井"找漏技术在临盘油田的应用 总被引:5,自引:1,他引:4
随着油田开发的逐步深入,油水井套管的损坏已成为一个比较突出的问题。为解决油水井套管技术状况监测难题,胜利油田临盘采油厂近年来应用井温、井径、超声成像及放射性同位素示踪等多种方法,取得了一定的应用效果。由于套管损坏的必然性和复杂性,仅采用一种方法就能解决套管井中的所有问题既不现实也不可能。文章针对不同的井下状况,采用井径测井、磁测井、井温测井组合,扬长避短,互相补充,取得了井下精确的现场资料,为下一步措施奠定良好的基础。实践表明,文章所介绍的三种不同的组合方式,收到了较为显著的应用效果。 相似文献

由于测井工艺不完善,以找窜为目标的噪声测井始终没有取得良好效果。为此,我们对噪声找窜测井工艺进行了模拟试验。试验表明:要实现噪声找窜,必须保持井内流体相对静止,通过相应工艺在窜槽层位人为造成压差形成窜流。 相似文献

井温在注产剖面解释中的应用实例 总被引:2,自引:2,他引:0
多参数组合测井是提高注入剖面和产出剖面测井资料解释成果可靠性的有效手段。井温测井资料在注入剖面解释中可用于辅助判断吸水层位及吸水级别,验证封隔器和死嘴是否密封;在产出剖面解释中,井温测井资料有助于判断主产层,分清大层段内小层或厚层内各部分产液情况,以及校验套管和水泥环的完整性。通过一些典型实例分析,说明了带井温曲线的组合测井综合分析在注、产剖面解释中的重要性。 相似文献

《Food Control》2018
Spices and herbs can contain toxin-producing bacteria and moulds, which can cause health problems for consumers and contribute to food spoilage and shelf-life reduction. The aims of the present work were (i) to determine the occurence and levels of B. cereus and moulds; (ii) to charactize the incidence and diversity of B. cereus emetic toxin (ces, CER), and diarrhoeal toxin-encoding genes (entFM, nheA, hblC, cytK) and toxigenic potential of Hbl toxin-producing B. cereus strains. Black ground pepper samples showed the most contamination with the highest concentration of B. cereus 2.49 log10 CFU/g. Moreover, cumin contained the most prominent mould concentration level of 3.6 log10 CFU/g. The most common moulds were Aspergillus and Penicillium spp. Compared to packaging type, all products acquired from the local market, except curry for B. cereus, exchibited high concentrations of B. cereus and moulds. Four genes were identified – 96% of B. cereus strains contained entFM, 94% nheA, 56% hblC, 42% cytK. None of the samples contained emetic toxin-encoding genes (ces, CER). Toxigenic potential of Hbl toxin was found in 72% of B. cereus strains. Different temperature, moisture levels and hygiene practices were observed at places of sale in local markets thus facilitating contamination and development of moulds. Moreover, the presence of B. cereus and its ability to produce toxins in spices and herbs, may suggest the need to establish microbiological criteria for mould and spore-forming bacteria in spices and herbs. 相似文献
