崭露头角的裸视3D显示技术

或许大家认为观看3D显示图像仍需配戴特殊眼镜观看。的确．早期显示屏生产厂商所发展的3D显示屏,若想观看3D图像是需配戴红蓝眼镜、偏光眼镜、快门眼镜等,然而如果没有3D眼镜,光靠3D显示屏亦呈现不出立体影像;另外．需戴眼镜的3D显示屏只能做到2视点的3D视角范围．     

印刷技术在无线电频率识别中崭露头角

安塞油田长6_1~(1(2))小层单砂体界面识别及划分方法

安塞油田长61油层总体连片性较好、稳定性较强,但层内单砂体稳定性却相对较差,变化较快,常有尖灭,且泥质夹层发育。因此,亟需建立一套单砂体划分方法,对其结构形态进行细致研究,为改善油藏开发效果提供新的思路。以长61(2)1小层为研究对象,通过野外露头和井下对比,深入剖析单砂体的形成背景及规律,并最终建立了有效的划分方法。     

The tectonic fracture modeling of an ultra-low permeability sandstone reservoir based on an outcrop analogy: A case study in the Wangyao Oilfield of Ordos Basin, China

Due to inherent limits of data acquisition and geophysical data resolution, there are large uncertainties in the characterization of subsurface fractures. However, outcrop analogies can provide qualitative and quantitative information on a large number of fractures, based on which the accuracy of subsurface fracture characterization can be improved. Here we take the tectonic fracture modeling of an ultra-low permeability sandstone reservoir based on an outcrop analogy, a case study of the Chang6t~ Formation of the Upper Triassic Yanchang Group of the Wangyao Oilfield in the Ordos Basin of China. An outcrop at the edge of the basin is a suitable analog for the reservoir, but the prerequisite is that they must have equivalent previous stress fields, similar final structural characteristics, relative timing and an identical depositional environment and diagenesis. The relationship among fracture density, rock type and bed thickness based on the outcrop is one of the most important fracture distribution models, and can be used to interpret fracture density in individual wells quantitatively. Fracture orientation, dip, geometry and scale, also should be described and measured in the outcrop, and can be used together with structure restoration and single well fracture density interpretation to guide fracture intensity prediction on bed surfaces and to constrain the construction of the 3D fracture geometry model of the subsurface reservoir. The application of the above principles shows the outcrop-based tectonic fracture models of the target ultra-low permeability sandstone reservoir are consistent with fractures inferred from microseismic interpretation and tracer tests. This illustrated that the fracture modeling based on the outcrop analogy is reliable and can reduce the uncertainty in stochastic fracture modeling.

洛阳杜康浙江露头

浙江市场上,白酒消费在当地酒水容量中占比不足35％,基本与黄酒、葡萄酒三分天下,且长期被外来品牌伊力特曲、泰山特曲所占据,浙江消费者对其他白酒品牌基本处于免疫状态。     

准噶尔盆地东部克拉美丽山白碱沟石炭系火山岩露头研究

白碱沟位于准噶尔盆地东部的克拉美丽山露头区。其石炭系火山岩剖面发育玄武岩、玄武安山岩、安山岩、流纹岩、火山角砾岩等多种岩石类型。白碱沟西沟石炭系剖面代表了巴塔玛依内山组的下部岩性特征,白碱沟东沟石炭系剖面代表了巴塔玛依内山组的中、上部岩性特征。白碱沟剖面总体上自下而上呈玄武岩-安山岩-流纹岩组合,形成基性火山岩-中性火山岩-酸性火山岩序列。这一火山岩序列特征符合岩浆演化规律,与钻井资料相吻合。

油水界面倾斜原因分析

根据渗流力学的理论计算,分析认为地下现今地层中水的运动不可能导致油水界面的倾斜;同时,又根据岩石物理的有关理论,分析了岩石物性导致油水界面倾斜的原因。分析研究认为,古水流导致岩石物性的差异,岩石物性的差异又导致毛细管压力曲线的不同,继而导致了油水界面沿古水流方向向上倾斜的现象。
