特低渗透油气藏成岩储集相的定量评价方法

针对陕北斜坡东部特低渗透储层受沉积作用和成岩作用两大因素控制的特点，利用灰色系统理论对成岩储集相进行了研究。分析了成岩作用综合效应及其相应的视压实率、视肢结率、视微孔率、成岩综合系数等定量指标和岩心分析数据，建立了成岩储集相综合评价参数、指标和分析方法。通过在安塞油田低孔隙度特低渗透长6。油藏储层的实际应用，对目的层段开展了Ⅰ，Ⅱ，Ⅲ和Ⅳ类成岩储集相的定量评价和油气富集描述，有机地集成和综合了多种信息，实现了成岩储集相对沉积学、岩石学和成岩作用等特征的综合表征，并划分出有利成岩储集相区域，为指导油田有利含油区块的筛选和开发决策提供了重要依据。     

聚合反应器制造质量控制要点探讨

聚合反应器是无法检修设备,不允许打开,所以聚合反应器的制造质量必须严格控制,在设备制造过程中,严格按照设计图纸、技术要求及国家现行标准,进行控制设备制造、检验和验收,使制造质量达到规定要求。     

The Challenge of the Market

Identifying markets for new or improved products for minor crops threatened with extinction is one critical component of any strategy intended to enhance prospects for sustainable production and use. Typically, however, activities linked to the sustainability of these commodities avoid addressing questions associated with assessing their commercial potential. After a brief review of this avoidance syndrome, this article presents a sample of practical, low-cost procedures to help evaluate the market prospects and procedures for crops like quinoa, while citing references to other methodological materials covering similar topics.     

Probabilistic analysis of uncertainties in seismic hazard assessment

Sources and current methods of analysis of uncertainty from randomness, fuzziness and ignorance or incomplete knowledge in seismic hazard assessment problem are briefly discussed at beginning; understandings of the authors are then presented in the following order. All three types of uncertainty come from incomplete knowledge. Probabilistic method can be applied to all of them, objective probability for random factors and subjective probability for the other two types of uncertain factors. Discrete subjective probability mass functions for incomplete and fuzzy factors can be obtained from logic-tree and membership functions respectively. Fractile curves may be used to show the scattering of any uncertainty factor, but a unified probabilistic treatment may be applied to any combination of all three types of uncertainty.
