三塘湖盆地条3井稠油形成条件分析

方法从盆地构造发育史和沉积演化特征入手，运用层序地层学和油气藏动态分析的方法，对条3井稠油的烃源岩、油气运移通道等进行了分析和探讨。目的分析三塘湖盆地条3井稠油的形成条件，为盆地今后的油气勘探指明方向。结果三塘湖盆地条3井稠油来自盆地东部的二叠系烃源岩；区域不整合面和逆冲断裂系统为油气提供了良好的运移通道；早期及同期形成的圈闭是油气聚集的有利场所；晚期较弱的构造活动为油气保存创造了有利条件。结论三塘湖盆地目前勘探的方向，一是衣盆地东部二叠系烃源岩沉积中心与条3井间的运移通道附近；二是在盆地南部与条3井北断层相当的逆冲（掩）断层下盘。     

台西盆地构造单元划分探讨

首次提出台湾中央山脉(褶皱带)以西与东南沿海间广大地区为统一的台西盆地。前新生代本区与中央山脉为统一的中生代盆地;古新世—始新世演化成东西两个断槽(一个在西带.一个位于中央山脉);渐新世以隆起为主,主要沉积区在中央山脉;中新世拗陷区主要在台湾海峡东侧至台湾麓山带;上新世一第四纪为造山期,台湾岛的滨海平原区为前陆盆地,沉积了巨厚的上新统和第四系。由西向东盆地可分为西部断陷带、中部隆起反转带和东部坳陷带,盆地南北地质差异也较大。     

西北侏罗系煤成油研究中的煤田地质学方法

运用煤田地质学方法分析、研究了西北侏罗系盆地的煤沼沉积环境演化类型(以下简称煤沼演化类型),划分出:①没有发育湖相建造;②含煤建造上覆缺失湖相建造;③具有完整湖平面变化旋四层序的三种煤沼演化类型;研究了西北侏罗系含煤盆地,尤其是第二和第三煤沼演化类型的煤显微组分组成和烃源岩的成熟度特征.根据西北侏罗系含煤盆地煤成油田形成和分布规律,依据煤沼演化类型、盆地沉积构造背景、有机岩组成特征等条件,提出了天山及其以北和塔里木周缘和祁连山两侧山前的前陆盆地等同沉积构造活动性较强的盆地是西北侏罗系煤成油勘探的有利区域,发育第一和第二煤沼演化类型的盆地及其伊犁和三塘湖盆地没有找到煤成油田的可能的看法.     

试论中国大陆经向和纬向石油富集“黄金带”特征

从目前勘探现状、盆地成因、产层的主要时代等因素分析,中国大陆含油盆地可划为从依兰-伊通-渤海湾-江汉盆地群构成的经向带,和从准噶尔-二连-松辽盆地群组成的纬向带,二者共拥有中国石油总产量的94%和总储量的99%.因而我们分别称为经向和纬向石油富集“黄金带”.本文从中国板块构造演化、成盆构造背景和成藏条件等因素,分析了经、纬向石油富集带的共性和个性,并与国内二类三种含油气大地构造单元对比,认为纬向油气富集带具有最有利的石油勘探前景,建议列为“九五”期间中国大陆石油勘探的重点地区,其中应特别加强准噶尔盆地,沙漠区的勘探力度,可望找到特大型油田。     

Electrochemistry of isopolytungstate mixtures

Solutions of isopolytungstates are of interest as the precursors for electrodeposited rechargeable tungsten oxides, and also in relation to hydrogen evolution catalysis. Understanding of isopolytungstate electrochemistry is complicated by numerous pH-dependent equilibria. This paper presents some data of dc polarography and UV absorption spectroscopy for solutions always containing several types of coexisting isopolytungstate species, in order to understand the individual electrochemical reactivity of certain isopolyanions.     

Rapid CO2 Evolution Method for Determining Shelf Life of Refrigerated Catfish

The feasibility of a CO₂ evolution method using an IR analyzer to evaluate the shelf life of refrigerated (4deg;C) catfish was investigated. Aerobic plate count (APC), and isoelectric focusing (IEF) of samples were compared with the CO₂ evolution rate (CER) determinations. The increase in CER (25.78 to 195.63 Lg^?1h^?1) for farm raised catfish stored from 0 to 10 days correlated highly with APCs (4.32 to 10.24 log CFU g^?1). The IEF data also confirmed the APC and CER results. Catfish spoilage was evident after 6 days at 4°C. Direct measurement of CER is a rapid and effective method to determine the microbial quality of catfish.     

Review of Constructive evolution: Origins and development of Piaget's thought.

Reviews the book, Constructive evolution: Origins and development of Piaget's thought by Michael Chapman (see record 1988-97990-000). Canadian developmental psychologists have been among the harshest critics, most articulate supporters, and most creative extenders of Piaget's theory. Michael Chapman's book is in this reflective and interpretive tradition. Chapman's primary goal in the book is neither to criticize, support, nor extend Piaget's theory (although he does some of each), but to clarify the meaning of the theory, and to specify its domain of application. Chapman does this by tracing the growth of Piaget's thinking using Piaget's autobiographical papers as a map. The first six chapters comprise Chapman's historical analysis, which begins with Piaget's adolescence, a point in life where Piaget was later to say that cognitive development ends (although he was to retract the claim still later in his career). In the last two chapters of the book, Chapman uses his historical analysis to clarify the philosophical and psychological significance of Piaget's theory. Chapman's book is an excellent integration of Piaget's theory in that it places the theory in the context of the questions that motivated it. But for all the clarity that Chapman's historical analysis brings to Piaget's thought, the analysis opens a number of new questions. What Chapman has done successfully is to provide a view of the nature, limits, and future of Piagetian theory by examining its origins and evolution.

东非海岸盆地下侏罗统沉积特征及其控源作用

下侏罗统烃源岩是东非海岸盆地的主力烃源岩。利用钻井、测井、地震及地球化学分析化验等资料,结合区域构造演化,对东非海岸盆地下侏罗统的沉积特征进行了分析和描述,并结合其烃源岩发育特征,对烃源岩的成因模式及其主控因素进行了刻画和评价。研究结果表明：①东非海岸盆地早侏罗世受区域构造作用影响,形成了狭长而闭塞的海湾沉积环境,发育河流-三角洲-滨浅海-局限海或浅海沉积体系;②下侏罗统发育的局限海相泥岩为盆地内的优质烃源岩,其TOC平均为4.2%,有机质类型以Ⅰ—Ⅱ₁型为主,已达成熟—过成熟演化阶段,泥岩厚度大且分布广,生烃潜力大;主力烃源岩的发育与展布受其独特的海湾沉积环境影响,由北向南盆地主力烃源岩的质量及生烃潜力逐渐变好;③东非海岸盆地发育局限海相沉积型、潟湖相沉积型和三角洲相沉积型3种烃源岩成因模式,其中局限海相沉积型烃源岩是盆地优质烃源岩的主要成因类型,岩性以稳定分布的厚层泥岩为主,夹薄层砂岩,总体评价为好烃源岩;④东非海岸盆地最有利的生烃区带位于鲁伍马盆地和坦桑尼亚盆地深水沉积的中心区域。该研究结果可为东非海岸盆地的油气勘探指明方向。     

东濮凹陷构造特征及古生界有利勘探区带评价

利用地震、钻井等资料,对东濮凹陷进行构造解析,并结合煤系源岩高热演化区的生气强度进行了研究区古生界有利勘探区带预测。研究结果表明：①东濮凹陷具有印支—燕山期挤压分区、古近纪拉张成带、沙四—沙三段沉积期断陷控洼、沙二段沉积期走滑成块的演化特征,从而导致古近系具有多断、多凸、多洼的结构特征。②东濮凹陷在多期构造应力叠合作用下形成“棋盘式”含油气系统,各含油气系统内油气普遍具有“上油下气、早油晚气、连续成藏”的特征,总体上发育4类油气藏,建立了弱改造型盆地“近源聚集、连续成藏、断超控富”的油气富集模式。③东濮凹陷中区构造改造弱,油气富集,南北向挤压断层控制着古生界残余地层的分布,是深层煤层气原生油气藏有利区带;在高热演化区以烃源岩为中心,利用多成藏要素叠合可优选出卫城—文留构造带为有利勘探区。
