The formation and distribution of high H2S gas underground for understanding the behavior of organic geochemistry is stuchied and fluid evolution of forming a more important scientific significance. By analyzing the distribution of eastern Sichuan H2S gas, natural gas in this area that there are two high H2S content areas; Kaijiang-Iiang Pinghai trough east of the plateau phase of the evaporation zone and in the open river-Liang Pinghai trough west of the open platform facies part of the well area. In the Jurassic-early Cretaceous, SO2-4 rich formation water continued along the original solution pores, dissolving suture, and breaks into the ancient reservoir addition, the occurrence of TSR reaction, and produce large amounts of H2S and C02 acid gas . These acidic gases produce in the early calcite cement dissolution, making the original pore expanding role in the transformation of the reservoir there.%在ARM平台上嵌入式Linux下使用多线程的技术,完成了小麦硬度检测系统的设计.系统的硬件系统使用模块化的设计方案,软件使用自定义的协议完成上下位机的通信.使用多线程技术实现了本系统的多任务的并发工作方式.运行结果表明小麦硬度检测系统能实时性好、稳定性高.
