火烧油层技术在庙5块低渗透稠油油藏中的应用

方法在物理模拟的基础上，利用数值模拟及油藏工程方法，对影响火烧油层的技术参数进行了优选研究，并对影响火驱成败的油藏地质参数、注气参数进行了分析。目的寻找适合庙５块低渗透稠油油藏的开采方法。结果提出了庙５块火驱的最佳开采方式、点火参数及注气参数；庙５块火驱生产后，平均单井日产液由０１ｔ上升到５６ｔ，平均单井日产油由０１ｔ上升到３５ｔ，生产２６ｄ后由于压风机供风不足被迫停止火驱注气；从数模结果看：火驱最终采收率可达３９８％。结论火烧油层是一种潜力很大的稠油开采方法，但其物理、化学反应机理复杂，火烧前缘难以控制；庙５块火驱初期虽然见到了一定的生产效果，但没有取得经济效益

CMOS电路中抗Latch-up的保护环结构研究

闩锁是CMOS集成电路中的一种寄生效应,这种PNPN结构一旦被触发,从电源到地会产生大电流,导致整个芯片的失效。针对芯片在实际测试中发现的闩锁问题,介绍了闩锁的测试方法,并且利用软件Tsuprem4和Medici模拟整个失效过程,在对2类保护环(多子环/少子环)作用的分析,以及各种保护结构的模拟基础之上,通过对比触发电压和电流,得到一种最优的抗Latch up版图设计方法,通过进一步的流片、测试,解决了芯片中的闩锁失效问题,验证了这种结构的有效性。     

Reconfiguration Aspects and a Reconfigurable Outer Block Interleaver for 3G Applications

Reconfiguration concept represents reconfigurable functionalities of the radio interface for mobile radio systems. Particularly for the physical layer, some possible reconfigurable architectures can be identified. We focus on outer interleaving for turbo codes, which can improve their performance in flat Rayleigh fading environment. The larger the number of columns in the outer interleaver, the better is the performance, but with the penalty of more complexity and delay. Furthermore, an incorrect choice of the number of columns can increase the bit and frame error rates. Therefore, it would be advantageous to reconfigure the outer interleaver in different operating environments with the optimum number of columns. Using two different data frame lengths, in this contribution simulation results are presented for the four possible outer block interleaver configurations specified for the 3GPP mobile standard in the case of flat Rayleigh fading channel. It is shown that different operating environments require an optimum number of columns in terms of bit error rate and frame error rate performance. Finally, frame fade duration is considered and the effect of the product of the Doppler frequency with the frame duration on the performance for the four different 3GPP outer block interleaver configurations is discussed.
