临南洼陷孔店至沙三沉积期构造对沉积的控制作用

盆地中沉积体系的形成演化受构造作用的控制或影响。结合地震资料解释,对临南洼陷构造特征和沉积充填演化特征进行分析,研究从孔店期至沙三期不同构造演化阶段沉积体系及砂体的分布规律,并在此基础上分析构造活动对沉积的控制作用。结果表明,从孔店至沙三期临南洼陷控洼断裂活动为走滑-伸展性质,控制了盆地结构和沉积砂体入盆位置、沉积砂体空间位置、展布范围和发育规模等。孔店期主要发育冲积扇和浅水的扇三角洲、三角洲,至沙三期由于断裂活动增强湖盆扩张发育深湖-半深湖,并在三角洲和扇的前缘发育滑塌浊积扇。三角洲在洼陷北部和南部都有发育,扇三角洲、浊积扇等发育情况北部好于南部。

Investigation on the application of reformed coke oven gas in direct reduction iron production with a mathematical model

To investigate the application of reformed coke oven gas （COG） in producing the direct reduction iron （DRI）, we simulated a countercurrent gas solid moving bed reactor in which the iron ore pellet was reduced by reformed COG. An ordinary differential equation （ODE） was set based on the unreacted shrinking core model considering both mass and energy balances of the reactor. The concentration and temperature profiles of all species within the reactor were obtained by solving the ODE sys tem. The solid conversion and gas utilization were studied by changing gas flow rate, solid flow rate, reactor length, and the ratio of O/CHa to guide the practical application of COG in DRI production. Model results showed that COG was suitable for the DRI production. In order to meet the requirement of the industrial production, the minimum gas flow rate was set as 130,000 Nm3/h, and the maximum production was 90 t/h. The reactor length and the mole ratio x（O）： x（CH4） were depended on the actual industrial situations.     

中东地区R油田Mishrif组储层主控因素及其分布规律

Mishrif组作为伊拉克东南部R油田重要的油气产层之一,储层成因及分布规律认识不清制约着该层系后备油气资源开发利用成效。本文综合岩石薄片、岩心物性、常规及特殊测井数据等资料,分别分析了沉积、成岩要素对Mishrif组储层的控制作用,认为R油田Mishrif组生物礁滩、滩前、滩后、潟湖相皆不同程度发育储层:规模性优质储层发育在生物礁滩环境,强烈溶蚀作用及弱胶结作用是重要成储条件,储集空间以溶孔、粒间溶孔及铸模孔为主;低能相带储层形成于弱胶结作用环境,未被胶结物充填保留的生屑颗粒间溶孔、粒内孔是储层发育的基础。对比不同类型储层岩电响应特征,刻画并描述了Mishrif组优质储层的分布规律:Mishrif组下部(MB段)生物礁滩储层物性优于上部(MA段)同类储层,优质储层位于准层序上部,受大气淡水溶蚀作用改造显著;滩后、潟湖相中等品质储层叠置发育在生物礁滩型储层上部,且由于差异胶结作用的影响使之在横向及垂向上表现出明显的非均质性。     

基于热处理加工工艺以延长模具使用寿命的分析

在模具设计和制造过程中,模具的使用寿命与热处理不当、选材不合适、模具结构不合理、机械加工工艺不合理、模具滑润不好、设计水平差等诸多因素有关。值得注意的是,在引起模具失效的各种因素中,热处理不当远高于其他几个方面。因此,笔者就如何从热处理方面来提高模具寿命谈一下自己的观点。
