油井负压冲砂装置研究

针对正常冲砂过程中存在的洗井液漏入油层和沉砂返回油层的问题，设计了一种负压冲砂装置，使用该装置能将原来的冲砂变成抽砂。使井底压力始终小于油层压力，达到在冲砂过程中保护油层的目的。文章对该装置进行了理论分析，给出了基本的计算方法。     

Use of a portable fluorescence imaging device to facilitate cleaning of deli slicers

Cross-contamination is a recognized food safety concern for deli departments, and deli slicers remain a particular concern. This study examines the use of a fluorescence imaging device to detect deli residues on deli slicers. Four cheeses and four processed meats were used for testing. For each commodity, the slicer was scanned at 475, 520, and 675 nm after slicing five times, after washing, and after sanitation. A 405-nm light source was used to excite fluorescence responses. Hyperspectral data were acquired for identified problem areas, and the three wavelengths used for scanning proved adequate to detect all deli residues. Most residues were found in three areas: around the blade and blade guard, on the surface where commodities were pressed during slicing, and on and around the spikes in the arm used to hold commodities. The number of residues detected decreased with cleaning and then sanitation; however, it was impossible to fully clean the slicer without using the imagining device to direct cleaning efforts. It is suggested that a fluorescence imaging device, or something similar, be adopted for routine use in delicatessens.     

全直径岩心分析装置及Archie公式在非均质储层的应用

指出了全直径岩心分析的Archie参数（m、n）对非均质储层含油（气）性评价的重要性。使用新疆测井公司自主开发的全直径岩心多参数分析实验装置，对全直径岩心进行实验方法研究。以DQ油田XX区块的非均质火山岩气层评价为例，由该区块全直径岩样获得了储层的物性和Arctfie参数，应用于该储层含气饱和度估算后，与密闭取心饱和度分析的含气饱和度结果比较，含气饱和度估算误差大致在5％以内，较Archie参数的理论值（m=n=2）估算的含气饱和度的精度高10％左右。考虑到非均质储层在岩性、物性、孔隙结构的特殊性，推荐使用全直径岩心分析方法应用于非均质储层的物性、含油（气）性的评价，并且重视模拟油藏条件的全直径岩心分析的方法研究。     

一种实用的CO2溶解气驱岩心洗油方法

为了提高岩心的洗油效率,开发了一种实用的CO₂溶解气驱岩心洗油方法。该方法在Stewart设计的CO₂溶解气驱方法的基础上,增加了洗油室抽真空、CO₂预清洗、溶剂回收3个步骤。使用自行研制的DGO-1型CO₂溶解气驱洗油装置,实验考察了新方法的洗油效果。6块不同孔隙度、渗透率的岩心的洗油结果表明,经过6~10次CO₂溶解气驱后,岩心荧光级别均小于3级,孔隙度和渗透率趋于稳定,可满足石油天然气行业标准SY/T 5336-2006的要求,且洗油时间(2~3天)较常规脂肪抽提洗油(2~3周或更长)有大幅度减少。该方法洗油原理清楚,洗油装置简单,易于操作,洗油效率高,清洁环保,推荐作为一种实用方法在岩石物理实验室推广使用。
