Potential risks of spectrum whitening deconvolution——compared with well-driven deconvolution

引用

Petroleum Science 2009年第2期6卷 146-152页

作者： Li guofa zhou Hui Zhao Chao State Key Laboratory of Petroleum Resource and Prospecting China University of Petroleum Beijing 102249 China Key Laboratory of CNPC Geophysical Exploration China University of Petroleum Beijing 102249 China

Deconvolution is widely used to increase the resolution of seismic data. To compare the resolution ability of conventional spectrum whitening deconvolution to thin layers with that of welldriven deconvolution, a complex sedimentary geological model was designed, and then the simulated seismic data were processed respectively by each of the two methods. The amplitude spectrum of seismic data was almost white after spectrum whitening, but the wavelet resolution was low. The amplitude spectrum after well-driven deconvolution deviated from white spectrum, but the wavelet resolution was high. Further analysis showed that if an actual reflectivity series could not well satisfy the hypothesis of white spectrum, spectrum whitening deconvolution had a potential risk of wavelet distortion, which might lead to a pitfall in high resolution seismic data interpretation. On the other hand, the wavelet after well- driven deconvolution had higher resolution both in the time and frequency domains. It is favorable for high resolution seismic interpretation and reservoir prediction.

基于传统共挤成型技术,提出一种先进的气辅多层共挤精密成型技术。研究表明,气辅共挤成型技术不仅可实现挤出制品尺寸的精确自动控制,而且还起到明显的节能降耗的效果。通过建立的稳态有限元数值算法,对传统共挤成型和气辅共挤成型的成型过程和离模膨胀过程进行了系统的对比分析研究,并探讨了气辅共挤成型消除整体离模膨胀的机制。结果表明,多层共挤成型芯壳层熔体的离模膨胀是由黏弹性熔体的二次流动引起,主要取决于芯壳层熔体二次流动的方向与强度。熔体二次流动的方向与第二法向应力差的正负号有关,而熔体二次流动的强度则与第二法向应力差大小成正比。气辅共挤成型的气辅口模段可通过气垫膜层的壁面完全滑移作用,有效减小或消除芯壳层熔体的第一和第二法向应力差,使其二次流动消失,从而达到消除口模整体离模膨胀的目的。因此,气辅多层共挤精密成型技术能精确地控制共挤成型的复合产品最终外形和尺寸与挤出口模的形状和尺寸完全相同。此外,研究结果还表明气辅共挤成型的挤出压力相对传统共挤成型可降低约30%以上。

如何准确预测和调控微装配界面熔接黏附脱黏剥离特性是聚合物模内微装配成型制备高性能微型机械运动的关键科学与技术问题。针对这一关键科学与技术问题,构建了模内微装配成型微型机械运动副界面熔接黏附脱黏剥离行为的模拟仿真平台和注射温度-材料副界面脱黏剥离断裂韧性参数-界面熔接黏附脱黏剥离特性的关联关系。研究表明,运动副微装配界面的启裂应力、临界应变能释放率和完全脱黏剥离驱动力与二次成型熔体注射温度呈正相关关系,降低二次成型注射温度,可以明显减小界面的启裂应力和临界应变能释放率,抑制微装配界面的熔接黏附,有利于降低微装配界面熔接黏附脱黏剥离的驱动力,提高微装配界面的可运动性能。
