廊固凹陷大兴断层对油气分布的控制研究

廊固凹陷断裂系统复杂，其中大兴断层是中西部的控盆边界断层，它通过对凹陷的构造样式、沉积特征的控制进而影响整个凹陷的油气分布。从区域构造背景和盆地的沉积演化角度，按不同段落断裂展布的方向、产状的陡缓、对沉积的控制作用以及不同层段物质组份的差异，将大兴断层划分为4段：北段、中北段、中南段和南段，各段又可进一步分为上下不同的两段。各段断层的结构、形态、伴生构造、活动时间等都存在较明显差异，通过控制物源而控制沉积相的展布、储层物性和生储盖组合。相应的伴生构造和沉积物发育特征导致构造、构造-岩性组合控制了油气的分布：北段下段、中北段下段近湖一侧是廊固凹陷中西部有利的油气聚集带；中北段上段发育的生物气藏具有一定的勘探前景。     

微构造的地震识别与应用效果

胜利油田的油气勘探具有较大的剩余勘探潜力，且大部分油气蕴藏在微构造油气藏中。微构造油气藏在胜利油田的勘探开发老区均有分布，纵向上从沙四段到东营组均有发育。该类油气藏埋深浅、储层物性好、产量高，具有较高的经济效益。微构造油气藏在国内外研究较少，国内外较注重目的层沉积微构造的研究，且主要是沉积微构造对注采关系的影响。在对复杂断块的精细研究中，以前研究的重点也主要集中在应用钻井资料对断层的成因和对断层封堵性的研究上，而对微构造圈闭的成因、识别及成图，一直没有进行系统的分类研究。文章划分了微构造的类型，研究了微构造的特点，并认为构造作用、沉积作用和后期改造作用是微构造形成的３种主要原因。同时，利用地震资料对微构造圈闭的识别方法和描述技术进行了探索，形成了一套具有针对性的技术系列，取得了显著的效果，这对油气田老区的滚动勘探开发具有重要的意义。

泌阳凹陷北部斜坡复杂断块群油田以断鼻、断块及断层+岩性油气藏为主,垂向含油层系多,平面上叠合连片,油气主要富集在鼻状构造主体部位的断鼻断块内。通过对研究区油气控制因素的分析,指出继承性的鼻状构造控制了油气聚集方向和富集程度,油气藏含油范围和油气藏高度则主要受断层封闭性和封闭程度的控制,油气分布规律受伸展构造所伴生的各种断块群构造型式的控制。

A Study on Turbo—rotor Multi—fault Diagnosis Based on a Neural Network

The multi-fault phenomena are common in the turbo-rotor system of a liquid rocket engine.As it has many excellent qualities,the neural network might be used to solve the problems of multi-fault diagnasis of a turbo-rotor system.First,the feature expression of a common turbo-rotor fault was studied in order to build up the standard fault pattern and satisfy the need of neural network studying and diagnosing.Then.the turbo-rotor fault identification and diagnosis problems were investigated by using a BP(back-propaga-tion)neural network.According to the BP neural network problems,the parallel BP neural network method of multi-fault diagnosis and classification was presented and investigated.The results indicated that the parallel Bp neural network method could solve the turbo-rotor multi-fault diagnosis problems.

Allocentric Versus Egocentric Spatial Memory After Unilateral Temporal Lobectomy in Humans.

Thirty patients who had undergone either a right or left unilateral temporal lobectomy (14 RTL; 16 LTL) and 16 control participants were tested on a computerized human analogue of the Morris Water Maze. The procedure was designed to compare allocentric and egocentric spatial memory. In the allocentric condition, participants searched for a target location on the screen, guided by object cues. Between trials, participants had to walk around the screen, which disrupted egocentric memory representation. In the egocentric condition, participants remained in the same position, but the object cues were shifted between searches to prevent them from using allocentric memory. Only the RTL group was impaired on the allocentric condition, and neither the LTL nor RTL group was impaired on additional tests of spatial working memory or spatial manipulation. The results support the notion that the right anterior temporal lobe stores long-term allocentric spatial memories. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Signal Integrity: Fault Modeling and Testing in High-Speed SoCs

As we approach 100 nm technology the interconnect issues are becoming one of the main concerns in the testing of gigahertz system-on-chips. Voltage distortion (noise) and delay violations (skew) contribute to the signal integrity loss and ultimately functional error, performance degradation and reliability problems. In this paper, we first define a model for integrity faults on the high-speed interconnects. Then, we present a BIST-based test methodology that includes two special cells to detect and measure noise and skew occurring on the interconnects of the gigahertz system-on-chips. Using an inexpensive test architecture the integrity information accumulated by these special cells can be scanned out for final test and reliability analysis.
