利用拟声波曲线进行高分辨率地震反演

由于地下情况的复杂性和地震原始资料的分辨率的影响,要得到一个令地质家和地球物理学家满意的结果还是相当困难,特别是井约束反演都要用到声波曲线,当声波曲线由于各方面的影响不能反映储层的真实情况时,反演的结果就会与实际情况相差很大,针对这种情况,提出了拟声波的方法来解决这个问题.介绍了测井约束波阻抗反演技术和拟声波技术的原理及方法.该反演方法是基于初始模型的反演方法,利用拟声波曲线代替声波曲线来建立初始模型,并进行波阻抗反演,可以大大提高反演结果对储层反映的精确度.该方法在实际的应用过程中得到了很好的效果.     

Overview of underground coal gasification operations at Chinchilla,Australia

Underground coal gasification (UCG) is a process which converts deep, un-mineable or difficult to mine coal resources into syngas which can then be converted into valuable end products such as electric power, liquid fuels, synthetic natural gas and chemicals. This paper provides a summary of the UCG operations conducted at the Chinchilla Demonstration Facility in Australia, focusing on gasifiers constructed using directional drilling. A number of the experiences and key lessons learned from operating multiple underground gasifiers over several years at the facility are described. Implications for the implementation in commercial projects using UCG are also discussed. Finally, the potential of UCG as a method for producing syngas from deep coal is discussed and some of the challenges and opportunities are summarized.

强风化灰岩块体落石几何特征的地质学意义

针对强风化片状灰岩块体,采用统计学方法得出强风化片状灰岩块石主要形状为块状、板状和长条状。块状灰岩的几何尺寸频率图具有相对集中性和阶段集中性;不同区域块石总体的长度、宽度和高度频率值具有不同的离散特性;不同区域的块石表现出长度、宽度、高度上的相似性和一致性,并具有一比例系数1.22。块状块石、板状块石和长条状块石长度比较发现,块状块石长度板状块石长度长条状块石长度;块状块石长度尺寸分布较为均匀,基本无间断值,而板状和长条状有明显的间断尺寸。不同区域的不同形状块石频率具有相似的规律,块状块石频率值最高,长条状块石频率值其次,板状块石频率值最低;不同区域不同形状块石在数量上具有一定的相似性,存在一比例系数1.92。强风化岩体块石几何统计特征具有岩体分级中节理参数选取的参考、落石灾害的群发性预测及危险性评价以及落石防治工程参数设计的依据3个地质学意义。     

New functional fibre in milk puddings: Effect on sensory properties and consumers' acceptability

The effect of the addition of a new functional fibre (high-amylose maize starch, HAMS, as a source of resistant starch), recently available in the market, on sensory characteristics and consumers' acceptability of milk puddings was studied. Milk puddings containing modified waxy maize starch and κ-carrageenan were produced with different HAMS concentrations (0, 1, 2, 3 and 4%). Higher HAMS concentration caused changes in the sensory characteristics of milk puddings. Particularly, sensory attributes such as some roughness, rough afterfeel and floury taste appeared. Besides, the addition of HAMS caused an increase in manual and oral thickness and a decrease in creaminess, melting, and sweetness. A HAMS enrichment level of 1.4% in this product was estimated as the maximum concentration that does not significantly modify consumers' overall acceptability. Using survival analysis the proportion of consumers who would buy milk desserts containing 1.4 % HAMS was estimated as 71%. Consumers more interested in consuming functional foods enriched with fibre were more tolerant to the sensory changes caused by the addition of HAMS to the milk puddings.
