赵41断块干扰试井资料分析

对晋县凹陷41断块油田采用小直径电子压力计试井新技术，成功地进行了干扰试井。通过对观察井、激动井所得试井资料的详细分析、评价，证实了干扰井组中各井间地层的连通性，为下一步实施注水开发提供了可靠的依据。同时，进行了地层产能的分析，做出了产能预测，认为随着原油流度、产能的降低，整个断块油藏产量将快速递减。因此，提出要对油藏及时补充能量，并采取原油降粘措施等建议。     

盐16井全封闭边界油藏的确定及评价

充分运用试井解释成果，以尽量少的井确定一个油藏的范围及储量面积，加快勘探速度，提高勘探效果，近年来在胜利油田得到了较充分的应用。根据盐16井的电子压力计探边恢复试井资料解释成果，确定了该井沙四段砂砾岩体为全封闭边界油藏，以及具体的形状、储量面积及边界大小，并对此进行了评价，为决策部门提供了准确的勘探依据。通过在盐16井南部钻的一口空井（盐161井），证实了本次试井解释结果的可靠性。     

Classification and Uncertainty Visualization of Dendritic Spines from Optical Microscopy Imaging

Neuronal dendrites and their spines affect the connectivity of neural networks, and play a significant role in many neurological conditions. Neuronal function is observed to be closely correlated with the appearance, disappearance and morphology of the spines. Automatic 3‐D reconstruction of neurons from light microscopy images, followed by the identification, classification and visualization of dendritic spines is therefore essential for studying neuronal physiology and biophysical properties. In this paper, we present a method to reconstruct dendrites using a surface representation of the dendrite. The 1‐D skeleton of the dendritic surface is then extracted by a medial geodesic function that is robust and topologically correct. This is followed by a Bayesian identification and classification of the spines. The dendrite and spines are visualized in a manner that displays the spines' types and the inherent uncertainty in identification and classification. We also describe a user study conducted to validate the accuracy of the classification and the efficacy of the visualization.

首次在南昌凹陷钻探的鄱参1井揭露了上三叠统安源组烃源岩，否定了该区没有晚三叠世沉积的传统认识，预示了南昌凹陷存在上三叠统的勘探新领域。通过对鄱参1井区地质结构的分析和综合研究，提出南昌凹陷是从晚三叠世以来受层滑倾滑构造控制的一个独立层块构造单元，构造较周边简单。上三叠统烃源岩具有多种母质类型和晚期生烃能力，和上覆白垩系共同构成重建型油气保存单元，有进一步勘探的价值，并以位于层块构造中带南部地区油气地质条件最有利。

通过对渤东凹陷烃源岩生烃潜力的系统评价，认为东营组烃源岩有机质丰度达到中等—好烃源岩标准，渤东、渤中凹陷烃源岩类比研究推测沙河街组烃源岩有机质丰度更高；东营组烃源岩Ⅰ、Ⅱ₁、Ⅱ₂和Ⅲ型有机质均有分布，但以Ⅱ₁、Ⅱ₂型为主；与渤中凹陷对比表明，两者在有机质丰度、类型和沉积环境等方面具有很大的相似性，推测两凹陷沙河街组烃源岩具有相同性质。油源对比认为，渤东凹陷油源主要为沙河街组烃源岩，东营组烃源岩贡献很少；盆地模拟结果显示渤东凹陷石油、天然气资源量分别为7.91×108 t和220.2×108 m3，其勘探前景良好。     

崖南凹陷烃源岩生烃及碳同位素动力学应用

针对目前琼东南盆地崖南凹陷天然气系统勘探存在的地球化学问题，采用近几年发展起来的生烃动力学及碳同位素动力学研究方法，以崖城组烃源岩干酪根热解生烃实验获得的气体产率和碳同位素数据为基础，建立了生烃动力学和碳同位素动力学模型，初步圈定崖13-1气田天然气主要来自崖南凹陷斜坡带崖城组含煤地层，烃源岩埋深在4300～6000 m之间，目前正处在主生气阶段；崖城组热解气碳同位素动力学研究表明，崖13-1气田天然气成藏时间较晚，属于“累积”集气成藏，成熟度在1.5%~2.3%之间，显然为烃源岩气窗阶段充注，因此有利于气藏形成与保存。     

Advanced error concealment for 1Seg video communication considering error propagation inside a frame

Transmission of compressed video over error‐prone channels may result in packet losses or errors, which can significantly degrade the image quality. Such degradation becomes even worse in 1Seg video broadcasting, which is widely used in Japan and Brazil for mobile phone TV services recently, where errors are drastically increased and the lost areas are contiguous. Therefore, the errors in the earlier concealed MBs (macro blocks) may propagate to the MBs later to be concealed inside the same frame (spatial domain). The error concealment (EC) is used to recover the lost data by the redundancy in videos. Aiming at spatial error propagation (SEP) reduction, this paper proposes an SEP‐reduction‐based EC (SEPEC). In SEPEC, besides the mismatch distortion in the current MB, the potential propagated mismatch distortion in the following to be concealed MBs is also minimized. Also, two extensions of SEPEC, i.e. SEPEC with refined search and SEPEC with multiple layer match, are discussed. Compared with previous work, the experiments show SEPEC achieves much better performance of video recovery and excellent trade‐off between quality and computation in 1Seg broadcasting. © 2012 Institute of Electrical Engineers of Japan.
