低渗透储层分类标准及其综合评价——以敖包塔-葡萄花油田FⅡ油层组为例

敖包塔-葡萄花油田钻遇扶杨油层FⅡ油层组有效孔隙度主要分布在10%~15%之间,平均为12.6%;空气渗透率一般分布在0.1~10×10-3μm2之间,属低孔、特低渗透性储层。通过对选用7项宏观参数与7项微观参数确定储层综合评价参数并建立分类标准,确定出每个评价参数的分级标准,将敖包塔-葡萄花油田FⅡ油层组的储层分为四类,其中Ⅰ类最好,为低渗透储层;Ⅱ类次之,为特低渗透储层;Ⅲ类再次之,为超低渗透储层;Ⅳ类储层最差,为极差储层。依据专家经验及大量反复实验的结果上确定了权重系数,预测了FⅡ油层组的储层有利区带,结果表明敖包塔-葡萄花油田FⅡ油层组以Ⅰ类储层和Ⅱ类储层区为主,其中最有利储层区(Ⅰ类储层区)主要呈条带状分布于研究区北部的葡332~葡54~葡115-51、葡31、葡462、敖10等井区。

大港油田低渗薄互层油藏整体压裂技术研究

针对大港油田油藏评价和产能建设重点区块——官984断块,开展了低渗、薄互层整体压裂改造技术的研究和应用工作。根据该断块油层薄、泥质夹层等特点,在压裂工艺上重点研究应用了支撑剂粒径组合、控制裂缝纵向延伸、压裂油层保护、压裂液快速破胶和裂缝强制闭合五大压裂配套技术。经现场实施,在压裂投产的8口油井中,平均单井产量达到了13．3t／d,整体压裂改造效果明显。     

复合砂体中单一河道的识别方法

自储层精细地质描述技术在大庆油田萨北开发区全面推广应用以来,解决了现阶段油田开发调整中的一些问题,但在北三西葡一组聚驱开采中发现,在大面积分布的河道砂体中,处在河道某些部位的注采井之间原属一类连通,但注入井注入状况不好,油井采出状况也不太好。经进一步研究表明,在这些大面积分布的河道砂体中还存在单一河道砂体边界。针对这种情况,在北三西展开了单一河道砂体的追踪。在研究过程中主要采取两点做法：一是根据砂体切割关系首次对复合砂体进行分类,从而有利于单一河道识别后对复合砂体内部连通关系的认识;二是提出了定量参数与定性参数相结合的单一河道识别方法,从而提高了单一河道识别的可操作性。     

An Ecological Perspective of Listeria monocytogenes Biofilms in Food Processing Facilities

Listeria monocytogenes can enter the food chain at virtually any point. However, food processing environments seem to be of particular importance. From an ecological point of view, food processing facilities are microbial habitats that are constantly disturbed by cleaning and sanitizing procedures. Although L. monocytogenes is considered ubiquitous in nature, it is important to recognize that not all L. monocytogenes strains appear to be equally distributed; the distribution of the organism seems to be related to certain habitats. Currently, no direct evidence exists that L. monocytogenes-associated biofilms have played a role in food contamination or foodborne outbreaks, likely because biofilm isolation and identification are not part of an outbreak investigation, or the definition of biofilm is unclear. Because L. monocytogenes is known to colonize surfaces, we suggest that contamination patterns may be studied in the context of how biofilm formation is influenced by the environment within food processing facilities. In this review, direct and indirect epidemiological and phenotypic evidence of lineage-related biofilm formation capacity to specific ecological niches will be discussed. A critical view on the development of the biofilm concept, focused on the practical implications, strengths, and weaknesses of the current definitions also is discussed. The idea that biofilm formation may be an alternative surrogate for microbial fitness is proposed. Furthermore, current research on the influence of environmental factors on biofilm formation is discussed.
