冀中坳陷东北部石炭—二叠系储层特征及勘探方向

渤海湾盆地冀中坳陷石炭—二叠系残留分布区即坳陷东北部的文安斜坡、杨村斜坡、大城凸起等地区,受印支—燕山和喜马拉雅期强烈的后期构造运动改造,历经差异升降和拉张断陷两大构造发育阶段,致使东、西部剥蚀带的埋藏史表现为沉降—抬升—沉降、沉降—抬升两种类型。区内沉积体系发育较为齐全,自下而上可以识别出滨海潮坪—沼泽、三角洲和河流等三大沉积体系;其中,三角洲和河流体系发育的分流河道、辫状河道砂岩分布范围广、厚度大,形成了该区最主要的砂体类型。区内砂岩储层在其间断埋藏成岩过程中,受表生淋滤作用和深部淋滤作用的影响,形成了较为发育的次生孔隙,孔隙度一般为15%～25%,大气水的深部淋滤作用又进一步改善了断层发育区的储集性能,并由此形成了该区优质的储层。综合评价认为,西部剥蚀带附近是最有利的勘探区带。

Key technologies of layout design of recycling plants of waste refrigerators

The present situations of waste refrigerators recycling and disposing were analyzed. Three key technologies of layout design of recycling plants of waste refrigerators were presented as follows: 1) establishment of recycling process of waste refrigerators; 2) the general plane layout of recycling plants; 3) the detailed layout of workshops of recycling plants. The focus of the three key technologies is to tackle the problem of the detailed layout of workshops of the recycling plants. By adopting Petri net, the model of logistics system of workshops was established and then optimized, and finally the detailed layout chart of recycling plants was gained. By adopting E-factory, the recycling plants were simulated. The results show that the method mentioned is effective.

Flow stress of high density polyethylene and nylon 66 at high rates of strain

Measurement of the flow stress of high density polyethylene (HDPE) and nylon 66 at strain rates of 10³ s^?1 using a split Hopkinson pressure bar technique is discussed. The flow stress at a strain of 10% has been determined for both polymers at 20°C. The intrinsic errors involved in this technique are briefly reviewed. The results indicate that the flow stress of HDPE and nylon 66 were 50MPa and 150MPa, respectively, at strain rates of about 10³s^?1.     

Using rainbow net simulation to measure fault tolerance in a multiprocessor

The Rainbow net simulation technique is applied to modelling the impact of system load and fault handling on the availability of a fault-tolerant multiprocessor architecture. Rainbow nets are described along with the motivation for creating this modelling technique. A Rainbow net fault-handling model is created for the fault-tolerant multiprocessor architecture and the topology is shown to remain constant in size, independent of the number of processor, memory and I/O elements configured in the system. Simulation is performed with a varying load in terms of the number of active jobs the system must support. Results are given showing how the fault-tolerant capability varies with load. Two new metrics for evaluating fault tolerance are introduced; namely full fault-tolerability and partial fault-tolerability. They are based on simple observations in the model.     

用有限带宽反射波波形分析法进行储层横向预测

以正演地震模拟为基础的有限带宽反射波渡形分析法是一种新的储层横向预测方法。首先利用波形分解确定地震反射层的地质属性,找出能反映岩性变化的反射波波形特征参数;然后,采用多元数据聚类分析和灰色系统理论完成储层横向的预测。文中以预测江苏 J 凹陷 F 构造上阜二段生物灰岩分布及厚度横向变化为例,简述了反射波波形分析的全过程。预测结果已为钻探证实。     

多量程数据采集记录装置的设计

通常的数据采集与记录装置不易实现多量程测量。通过对标度方程进行分析得知,要改变量程只须改变两个参数——标度因子和量程下限。我们设计了一个使用单片机的多量程数据采集和记录装置,能处理多达256种量程。本文叙述了算法分析、硬件和软件的设计以及该装置的性能指标。
