用常规电阻率测井资料确定水淹层的剩余油饱和度

油田综合含水越来越高，利用电阻率测井资料确定地层的剩余油饱和度变得非常困难。针对这一问题，提出了确定地层水民阻率和含油饱和度的方法。（１）利用已知的地怪水分析资料，采用井下自然电位刻度，井间对经和双自然电位一方法来示准地层水混合电阻率，然后利用相邻井相同地层的电阻率对比方法求含水饱和度。（２）利用电阻率的横向探测特性，避开阿尔奇公式中ｍ、ａ选择上的困难，采用横向法计算水淹层目前的含水饱和度。利用以     

Intelligent Control of Consolidation and Solidification Processes

Intelligent processing of materials (IPM) deals with the integration of process models and in situ sensors into an intelligent process controller to achieve desired material properties. IPM-based control systems recently have been developed for both consolidation and solidification processes. This article explores the application of models based on the finite- element method (FEM) to develop process actuation systems, to design process schedules and component shape, and to develop a control model with which to control the process. The results in this article were presented at the AeroMat ’93 Advanced Aerospace Materials/Processes Conference and Exposition, Anaheim, CA, 7–10 June 1993     

二流量试井工艺及资料解释分析方法

描述了二流量试井工艺的实现，从常规分析和双对数曲线拟合两上方面，给出了二流量试井的资料解释分析方法，分析认为二流量试井同样可以计算出正常关井测压力恢复（或压力降落）资料所解释的油藏及流体参数。这种试井方法不但可以减少因正常关井测压对产油量和注水量的影响，而且可以减缓因突然关、开井造成的套管变形或损坏。实践证明，该试井技术方法具有较好的经济效益和应用前景。     

Familiarity and plausibility in conceptual combination: Reply to Gagné and Spalding (2006).

E. J. Wisniewski and G. L. Murphy (see record 2004-22496-015) suggested that the apparent effects of relation frequency in C. L. Gagné and E. J. Shoben's (1997; see record 1997-02349-004) conceptual combination experiments could be explained by differences between the familiarity and plausibility of their stimuli (noun-noun phrases). However, C. L. Gagné and T. L. Spalding (see record 2006-20573-017) argued that Wisniewski and Murphy's measures of plausibility and frequency are both sensitive to relation frequency. They also suggested that the stimuli were mostly novel, such that differences in familiarity could not explain Gagné and Shoben's findings. The current authors focus on the theoretical rationale for the plausibility and familiarity variables, arguing that the original interpretation of their findings is correct.

Integrated distributed intelligent system for process-control system design

In process-control system design, the Computer Aided Design (CAD) techniques have evolved a new generation of design techniques. This also paves the way for implementing Computer Integrated Manufacturing Systems (CIMS). However, the key issue to accomplishing the objectives in CAD is the automation of conceptual design. This paper first introduces the fundamentals of conceptual design for process-control system design. Then, a strategy to solve the problems in conceptual design is proposed. The associated system configuration and software implementation platform for developing intelligent systems for process control system design are presented. Finally, an application case is studied.

试油层产液性质的多参数综合判别方法研究

准确地判断储层的产液性质,是试油选层和试油方案优化的重要依据,目前常用的判别方法是基于电测解释结论的多因素经验判别,有较大的人为性和随意性,致使正判率和符合率相对较低,一方面增加了无效的试油工作量,另一方面,增加了漏试油气层的风险.为解决这一问题系统收集和统计了塔里木油田碎屑岩地层反映产液性的录井、测井资料和试油成果资料,通过综合分析对比,提出了预测储层产液性质的新方法--综合权值法.该方法通过一定的规则给电测解释结论、岩心含水迹象、滴水试验、含油饱和度、孔隙度、原油粘度等与产液性相关的因素赋以权值,从而求得综合权值,进而对储层产液性质进行综合判别.综合权值法明显优于单纯的电测解释,使油气水层解释的平均符合率和平均正判率都提高了20%.利用该方法判断储层产液性质具有操作简单、判别率高等优点,对于更合理地优选试油层位和优化试油方案具有重要的实际应用价值.

鄂尔多斯盆地鄂北地区现场气测录井由于受多种因素影响,解释符合率相对较低。针对这一问题,在探讨影响气测录井显示因素、识别气测异常的基础上,分析了消除影响因素的途径和校正公式,建立了随钻全烃与全脱全烃的关系式,论述了地面和地层含气量计算方法。在初步评价气显示性质条件下,经统计分析得出了应用4参数——峰面积、校正全烃值、全烃计算值和地层含气量加权分值的解释评价标准,为鄂北地区气测录井解释评价和产能的初步预测探索了一种新模式,不但解决了鄂北地区气测解释符合率低的问题,而且对于深入开展气测录井参数与油气解释评价研究具有一定的参考意义。     

基于智能模糊控制策略的有源消声

有源消声是一种有效的低频噪声控制方法，由于空间有源消声过程具有时变性和非线性，传统的自适应算法不能进行很有效的控制。本文采用智能模糊控制策略，建立了基于智能模糊控制策略的有源消声系统，通过实验与传统自适应控制算法的消声效果作对比分析，证明智能模糊控制器不但控制速度快，易于实现，而且消声效果明显优于后者，具有较大的应用推广价值。
