查询词典 gas attack

For 4-pass HAVAL, we describe a practical attack for finding two-block collisions with 2~(36) computations. Using the more complex message modification technique, the complexity can be improved to 2~(30). In addition, we show that collisions for 5-pass HAVAL can be found with about 2~(123) computations, which is the first attack more efficient than the birthday attack.

该方法的推导思路是：假设在某一控制储量条件下，联立求解气藏物质平衡方程式和气井二项式采气方程，计算气井采气曲线并将其与实际的采气曲线相匹配，最后确定储量、产能参数。该方法不需要较长的多次关井复压资料，在气藏受水驱影响较小时，还可计算一口探井或气藏试采早期所反映出的气井控制储量，在气藏生产中得到应用，计算结果较为可靠

The study shows that in various continental downfaulted basins in eastern China,the China East Sea basin of the southeast sea region and the continental shelf—Qiongdongnan basin and Zhujiangkou basin—of the northern South China Sea,CO2 in CO2 reservoirs and CO2-rich oil/gas reservoirs is of typical volcanic mantle-derived type and that its migration and concentration is mainly controlled by mantle-derived volcanism and gas-conducting distribution of deep basement faults connected with the gas source at depth. CO2 is mainly sourced from substantial amount of CO2 associated with mantle-derived volcanism at the deep level of the crust. CO2 in the CO2 reservoirs and CO2-rich oil/gas reservoirs in the Yinggehai basin on the continental shelf of the northern South China Sea is of crust origin and crust-mantle mixing origin and mainly controlled by local,layer-by-layer and zone-by-zone,multiple intrusion of late hydrothermal fluids in mud diapir areas and physico-chemical processes of very thick Pliocene-Miocene marine calcareous sandstone and mudstone.
