圈闭要素计算方法及应用效果

断块油田的油气聚集和分布,在很大程度上受各种类型的断层所控制。这种油田具有构造面貌复杂、含油层系多、油水关系复杂、含油丰度差别大等特点,给油气勘探和开发造成了许多困难和不便。目前,有关断块构造圈闭的统计尚无统一标准。以往所用的取值方法是沿用背斜圈闭的要素统计方法,不能适用于复杂的断块构造圈闭。本文以断层圈闭特点为基础,以影响圈闭性能的各种因素间的函数关系为依据,提出了具有较厚盖层和储层地区的断层圈闭要素的计算方法。将此法应用于东濮凹陷,取得了较高精度的含油圈闭面积。

Test Generation for Crosstalk-Induced Faults: Framework and Computational Results

Due to technology scaling and increasing clock frequency, problems due to noise effects lead to an increase in design/debugging efforts and a decrease in circuit performance. This paper addresses the problem of efficiently and accurately generating two-vector tests for crosstalk induced effects, such as pulses, signal speedup and slowdown, in digital combinational circuits. These noise effects can propagate through a circuit and create a logic error in a latch or at a primary output. We have developed a mixed-signal test generator, called XGEN, that incorporates classical static values as well as dynamic signals such as transitions and pulses, and timing information such as signal arrival times, rise/fall times, and gate delay. In this paper we first discuss the general framework of the test generation algorithm followed by computational results. Comparison of results with SPICE simulations confirms the accuracy of this approach.

Workload Distribution in Fault Simulation

Simulation at the gate level is computationally very expensive.Parallel processing is one technique to reduce simulation time.Possessing knowledge of the distribution of computational activity insimulation can aid in parallelizing it efficiently. We present a newcharacterization of the distribution of the computational workload infault simulation. An empirical analysis shows that the workloaddistribution is circuit specific, and is largely independent of thevector set being simulated. An inexpensive method to predict theworkload distribution is also discussed.
