Abstract: 辽河油田锦612复杂断块油藏下第三系沙河街组三段浊积砂砾岩储层厚度变化大,分布不稳定,纵、横向非均质性都很强。在油田开发阶段,地质工作者的任务是对油藏及其参数做出预测,落实储层横向变化特征,搞清油藏的非均质性特征,降低开发井部署风险。常规地面地震方法难以精确地用于落实井旁精细构造和预测岩性、储层横向变化。介绍了VSP(垂直地震剖面法)技术的基本原理、零偏和非零偏两个方面的数据采集与处理。以锦612-22-36和锦612-8-20两口井为例阐述了VSP资料的应用情况及效果。VSP技术大大提高了三维地震资料的分辨率,在地震剖面与地质层位之间架起了一座桥梁,准确地落实了锦612断块北部、西部断层的位置,搞清了储层在北部、西北部方向上的分布特征,为锦612断块油田扩边挖潜提供了重要的依据。

Abstract: The reservoir of Dujiatai in the north of Huanxiling Oilfield is of low porosity, low permeability and high heterogeneity. The characteristics of the reservoir and the microfacies in the study area was analyzed and researched. The characteristics of the microfacies, including underwater channel, underwater interfluve, debouch bar and sheet sand, were analyzed in the area. The microfacies model and the reservoir model of the study area were built up by using fine grid and lots of indicators in three target blocks. The results show that, under the control of the facies model, the reservoir model can show the underground facts better, and the model is fit for the work of developing the remaining oil.
OBJECT-FITTED FDTD METHOD BASED ON MEI-ABC
基于MEI方法的贴体网格FDTD方法

Abstract: The finite difference time domain (FDTD) computational zone was truncated by an artificial boundary, of which the geometric shape was conformal with the boundary of an arbitrary shaped scatterer. The external conformal mesh was generated by the Thompson transformation.On the truncating boundary, the time domain measured equations of invariance (MEI) were applied as a local absorbing boundary condition. So the FDTD computational domain was compressed remarkably. The numerical experiment proved that the requirement of computer storage is reduced while the numerical accuracy is not decreased.
指导油气勘探的新思路——从含油气系统到油气成藏动力学

Abstract: 简要介绍了含油气系统研究的内容与方法并对其进行了客观评价,指出了其局限性.系统介绍了油气成藏动力学概念的产生、内涵和外延以及研究方法,比较了含油气系统和油气成藏动力学两大概念的关系.认为: ①油气成藏动力学是系统论和动力学理论与传统的石油地质学相结合并应用于我国复杂地质情况的必然产物. ②在含油气系统宏观思想指导下进行成藏动力学过程研究是高等石油地质理论发展的必然趋势.
辽河盆地欢喜岭油田欢北杜家台油藏扇三角洲储层地质建模及其应用效果
,宋兴文,张庆龙
天然气地球科学 , 2008,
Abstract: ?辽河盆地欢喜岭油田欢北杜家台油藏具有低孔、低渗、非均质性强的特点,经20多年的开发,措施产量下降,层间矛盾日益突显。沉积微相特征分析表明,扇三角洲前缘亚相是研究区主要的沉积相类型;通过对水下分支河道、水下分支河道间(湾)、河口砂坝和前缘席状砂等沉积微相的岩性、电性和沉积构造特征进行分析,优选出3个有利目标区块,采用小网格模拟出研究区沉积微相模型,并在此基础上建立了储层物性参数模型。开发验证结果表明,相控条件下所建模型更接近地下地质实际,可为老区剩余油挖潜提供依据。

Abstract: 通过棉花生产形势分析,指出粮棉争地是棉花生产徘徊的主要矛盾,并提出了粮棉碰撞系数的概念和指标。对不同熟制地区粮棉碰撞系数的研究认为,发展棉田多熟种植是解决粮棉矛盾的有效途径。从今后棉花生产区域布局讲,认为在主攻新疆棉区棉花生产的前提下,应通过套种稳定黄淮海棉区棉花播种面积,适当消减粮棉矛盾突出棉区的棉花播种面积。

Abstract: As the most basic production unit, eco\|economy systems of farming and grazing households are of significance to the implementation and outcome of national policies. In this paper, eco\|economy systems of farming and grazing households, in Mu Us sandland acrossing Inner Mongolia Autonomous Region and Shaanxi Province,were studied by emergy theory and emergy analysis methods. The emergy input and output structure of different industrial models in Wushen banner, where grazing is dominant, and Yuyang district, where farming is the case, have been compared and analyzed. The total characteristics of pattern and development of typical eco\|economy systems of farming and grazing households are described and compared quantitatively by net emergy output ratio, emergy investment ratio, environmental loading ability, emergy power density, productivity of unit acreage, emergy cost per capita, emergy possession per capita, system production priority, system stability index and sustainability index. We hope our study could help to provide strategies for development and optimization of farming and grazing household industrial models in farming\|dominant zones and grazing\|dominant zones of Mu Us sandland.

Abstract: Aiming at real productivity of frail farming and grazing ecosystems in Mu Us sandland, basing on coupling theory of complex ecosystem, Uxin banner where grazing is dominant and Yuyang district where farming is the main character were selected as research object by means of using emergy theory and analytic methods, it analyses the primary productivity, secondary productivity and the coupling status of the farming and grazing system in those two areas for 27 years. And it comes up with a possible evolvement regulation of the extent of agro-ecosystem coupling. The results show that the industrial development model of Yuyang distric is farming-dominant, but Uxin banner is the grazing-dominant; Yuyang district has the tendency of pig, poultry production, but Uxin banner has the tendency of herbivorous animal production; the primary productivity, secondary productivity, A, B and SCD in those two areas are all increasing, and the SCD has the increase in the shape of "three-stage" in 27 years. In conclusion, this paper brings forward the developmental methods of farming and grazing ecosystems coupling in Mu Us sandland, it is expected to provide credible theory supports and direction to healthy development of the farming and grazing ecosystems.
TWO-STEP S THOMPSON-FDTD METHOD
Thompson-FDTD方法中的两步法

Abstract: This paper combines the differential-Thompson transformation involved in hydromechanics with the finite difference time domain (FDTD) technique to form Thompson-FDTD method. This method is applied for the first time to calculate the electromagnetic scattering properties of arbitrarily shaped dielectric objects. This method has at least two obvious advantages: it can transform arbitrary shaped bodies into regular structures and thus the boundary conditions are matched accurately; it can wilfully dispose the grid distribution and thus better numerical accuracy is achieved. The numerical simulation further confirms its validity.
