基于沉积时间单元的单砂体研究

以尕斯库勒油田N₁—N₂¹油藏Ⅱ号断层上盘Ⅶ砂组辫状河三角洲前缘亚相为例,探讨了基于小层规模的沉积时间单元划分、单砂体的含义与识别标志及构型模式。研究表明,根据自然伽马半幅点可以将小层细分为储层沉积时间单元、隔层沉积时间单元,并在储层沉积时间单元中识别出区域夹层。区域夹层与隔层沉积时间单元为泥岩沉积,储层沉积时间单元在横向上为砂泥岩间互沉积。在此基础上,提出了单砂体的完整概念,认为单砂体就是在三维空间被周围非渗透性的封隔层所包围的独立砂体。并指出了单砂体受沉积、构造及成岩三大因素控制,明确了在这三大因素控制下单砂体的识别标志,同时总结出了单砂体的基本构型模式。笔者成功地将这套研究方法应用于尕斯库勒油田Ⅶ—5小层,把原来小层级别的两个单砂体划分为沉积时间单元级别的17个单砂体,大大提高了单砂体的研究精度。

机器人通过奇异位形的运动学分析及仿真

研究了一种分析机器人奇异位形的新型控制方法。该方法使用线几何理论分析机器人线性相关的关节轴线矢量,从而识别机器人奇异方向和奇异关节轴,并将线性相关矢量对应的Jacobian矩阵进行列删除;使用反螺旋理论区分工作空间的可行运动和不可行运动,将不可行运动对应的Jacobian矩阵的行进行删除。当机器人失去一个自由度时,相应满秩Jacobian矩阵由66简化为55,使机器人在奇异位形处仍能获得精确解。通过对PUMA机器人仿真研究,结果表明了该方法的有效行。

A multichannel neural signal detecting module:Its design and test in animal experiments

A four-channel neural signal detecting module with an implantable 12-contact cuff electrode was designed for real-time neural signal recording on peripheral and central nerves. The mathematic coupling model between nerve and electronic system was analyzed. Electrode connection configurations were considered. The detecting circuit included an input coupling network, a pre-amplifier, and some filtering and notching stages. Shield guarding and the right-leg-driven circuit were developed for further elimination of common mode interference. By electrode switches, the module could cooperate with a nerve functional electrical stimulation circuit, building a neural channel bridge-connection system. It was tested by recording experiments on rat’s sciatic and spine nerves. The signals in spontaneous and evoked conditions have been captured successfully. In addition, an implantable neural signal detecting CMOS IC has been introduced.
