提高储层预测精度技术思路与对策

采用地质、地震、测井人员协同一体化作业，对地下地质目标进行综合预测与评价，可提高储层预测精度，降低预测结果的多解性。主要方法是针对不同的区块，采用不同的方法和对策，首先从单井储层划分对比入手，建立储层沉积模式，同时对地震数据目的层段进行精细解释，建立地层构造模式，用沉积、构造等地质规律来指导和约束反演；利用测井资料对地震资料进行精细标定，建立各井的单井波阻抗模型，建立井数据和地震数据沟通的桥梁；在严格的测井约束、地质模型约束、层位控制下进行储层反演；充分利用地质、地震反演结果、地震参数提取及分析结果、测井、测试和分析化验等资料对储层预测结果进行综合分析与评价。该方法应用于长庆、大庆、准噶尔等实际区块，取得了较好的效果。

Unix tools as visual programming components in a GUI‐builder environment

Development environments based on ActiveX controls and JavaBeans are marketed as ‘visual programming’ platforms; in practice their visual dimension is limited to the design and implementation of an application's graphical user interface (GUI). The availability of sophisticated GUI development environments and visual component development frameworks is now providing viable platforms for implementing visual programming within general‐purpose platforms, i.e. for the specification of non‐GUI program functionality using visual representations. We describe how specially designed reflective components can be used in an industry‐standard visual programming environment to graphically specify sophisticated data transformation pipelines that interact with GUI elements. The components are based on Unix‐style filters repackaged as ActiveX controls. Their visual layout on the development environment canvas is used to specify the connection topology of the resultant pipeline. The process of converting filter‐style programs into visual controls is automated using a domain‐specific language. We demonstrate the approach through the design and the visual implementation of a GUI‐based spell‐checker. Copyright © 2001 John Wiley & Sons, Ltd.

Development of nano indium tin oxide (ITO) grains by alkaline hydrolysis of In(III) and Sn(IV) salts

Indium tin oxide (ITO) nano powders of different compositions (In: Sn = 90: 10, 70: 30 and 50: 50) were prepared by heat treatment (300-450°C) of mixed hydroxides of In(III) and Sn(IV). The hydroxides were obtained by the reaction of aq. NH₃ with mixed aq. solutions of In(NO₃)₃ and SnCl₄. FTIR and TG/DTA studies revealed that powders existed as In(OH)₃H₂O—SnO₃H₂H₂O in the solid state and then they transformed to In₂O₃—SnO₂ via some metastable intermediates after 300°C. Cubic phase of In₂O₃ was identified by XRD for the oxides up to 30% of Sn. Particle size measurements of the solid dispersed in acetone and SEM study for microstructure showed that the oxides were in the nano range (55-75 nm) whereas the size range determined from Debye-Scherrer equation were 11–24 nm.     

注硼中子寿命测井注硼工艺优化设计

注硼中子寿命测井是一项水淹层测井新技术 ,对老油田的产层分析评价、剩余油含量估算等方面发挥了重要的作用。但测井施工时 ,往往由于注硼工艺不当导致硼酸的渗吸量难以准确反映地层可动水的含量 ,从而产生解释上的困难和误区。在渗流与扩散理论相结合的基础上 ,结合华北油田的施工实践 ,介绍了确定注硼管柱、硼酸用量、注硼压力以及硼酸扩散时间的基本原则和实际经验 ,为工艺的优化设计提供了一些方法与思路
