复杂断块油藏残余地层格架的建立及油层细分方法

海拉尔盆地是大庆油田勘探开发的重点地区,由于该地区在地史时期内经历过多期强烈构造运动,使该断陷盆地分割性强,地层往往呈残余状态.应用陆相层序地层学原理和地震相、沉积相、岩石相及测井相研究资料,对海拉尔盆地贝尔凹陷南一段内部层序界面进行了识别,并对地层缺失层段进行了确定和恢复.结果表明,南一段沉积过程中经历了3次湖泛作用和1次沉积转换作用,相应地形成了3个稳定泥岩段及1个由进积到退积的沉积转换面.通过基准面旋回变化过程中沉积湖泛面和转换面的追踪对比所建立的南一段残余地层等时地层格架,可以使目的层段内的油层组划分对比具有等时性,所建立的标准剖面可用来有效识别不同成因类型的地层缺失和缺失厚度.

吉林省梨树县石岭镇榆树林村—放牛沟登娄库组剖面沉积演化特征

本剖面地处吉林省四平市梨树县石岭镇境内,区域构造虽属郯庐断裂带北段西支依兰—伊通断裂带,但剖面地层形成年代却早于依兰—伊通断裂带【1】。剖面出露的登娄库组地层厚度共288.60m,其底部与营城组火山碎屑岩成角度不整合接触,上部地层未完全揭露。通过对剖面地层的细致考察同时结合区域地质资料,该剖面登娄库组地层主要沉积了一套粒度较粗的陆源碎屑岩,岩性以砂岩、砾岩为主,总体反映了构造运动强烈、周边地形起伏大、山区剥蚀强烈等特点的沉积环境。受断陷脉动式沉降【2】活动的影响,地层沉积相演化规律为：湖相→扇三角洲相→湖相→扇三角洲相,并在湖相和扇三角洲相研究的基础之上进一步识别出4种沉积亚相和8种沉积微相。

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach
