层序探油人的求新之旅

层序地层学作为一种新理论和新方法,于上世纪八十年代中后期诞生于国外海相盆地研究中,并且在油气勘探开发中取得了成功。如何把广泛应用于海相的层序地层学理论应用于我国陆相湖盆的勘探开发中?姜在兴教授及其课题组成员经过了十五年的理论研究和实践探索,终于找到了答案。     

鹤岗盆地石头河子组层序地层与聚煤作用

黑龙江省东部的鹤岗盆地是早白垩世开始形成的众多陆相断陷盆地之一,其主要含煤地层为早白垩世石头河子组。在鹤岗盆地西部矿区,主要通过钻探、测井资料及层序地层学理论等方法对石头河子组进行层序地层和古地理的分析。在石头河子组中识别出冲积扇、辫状河、曲流河、湖泊三角洲及湖泊等5个沉积体系及相应的11种沉积相类型,在此基础上将石头河子组划分为一个三级复合层序,并在层序格架下对其古地理及聚煤作用进行了分析,得出矿区厚煤层主要发育在湖侵体系域（TST）和高位体系域（TST）中的结论。最后提出了今后的勘探工作重点应往矿区的东北部转移的建议。

文章以我国东部小型箕状断陷湖盆的典型代表——南襄盆地为例,通过层序地层学研究,在第三系核桃园组地层中识别出4个三级层序。从地震反射结构、沉积结构、沉积序列等方面入手对该湖盆缓坡带的沉积体系特征、沉积模式进行了探讨,进而总结出缓坡带的2种沉积体系,提出与沉积体系相关的5种油气成藏模式。     

太原西山地区石炭-二叠纪沉积环境演化

利用野外露头、剖面、钻孔岩心等对太原西山地区石炭-二叠纪地层沉积相进行分析,识别并总结出台地-泻湖、障壁岛-泻湖-潮坪、浅水三角洲和河流4大沉积体系以及若干沉积相类型.该区晚石炭世本溪组沉积期主要发育台地-泻湖沉积体系;晚石炭世-早二叠世太原组沉积期以障壁岛-泻湖-潮坪的障壁海岸沉积体系为主,其次发育碳酸盐台地相和沼泽相.早二叠世山西组沉积期及以后,整个地区发生区域性海退,以浅水三角洲和河流沉积体系广泛发育为特征.沉积环境的演化经历了早期的陆表海、中期海陆过渡沉积和晚期的三角洲、陆相河流沉积,聚煤作用发生于太原组和山西组沉积期.     

破译集世界级难题之大成领域——海相深层碳酸盐岩天然气成藏机理、勘探技术与普光大气田的发现

陆相油气勘探理论支撑了中国多半个世纪的石油工业,随着陆相油气田勘探开发程度的提高,海相层系已成为我国油气勘探的主要接替领域。全球高达90%的油气储量发现于海相地层,而我国探明率仅10%左右。中国海相地层与世界相比,时代古老、多期改造、地表复杂、埋藏深,尤其南方地区,因而南方海相油气勘探面临的是世界级难题。2007年2月27日,在人民大会堂召开的全国科学技术奖励大会上,由中国石化部署,南方勘探开发分公司实施,同时联合中国石油大学、西南分公司等多家企业、科研院所和大学完成的"海相深层碳酸盐岩天然气成藏机理、勘探技术与普光大气田的发现"被授予国家科学技术进步一等奖,此项技术的产生,带动了四川盆地海相深层天然气储量增长高峰,推动了南方海相乃至中国海相油气勘探的快速发展。从而破解了在中国面临的这一世界性难题。     

鄂尔多斯盆地子长-延长井区山西组沉积相研究

鄂尔多斯盆地子长-延长区块是延长探区重要的勘探地区,对该区山西组地层的专题研究很少,利用地震资料进行的研究更少.利用测井、地震、地质资料相结合的方法,通过对测井相、地震相、地层厚度、地震资料构造成图,结合古地理背景沉积环境综合分析,对鄂尔多斯盆地子长-延长区进行了沉积相研究.研究表明,研究区山西组沉积类型主要为河流三角洲,并识别出三角洲前缘亚相和水下分流河道、水下分流间湾、河口坝等多种沉积微相,对研究区山西组沉积环境进行了分析,研究成果为进一步勘探开发提供依据.

十屋地区近期油气勘探进展与近中期的勘探方向表明,隐蔽油气藏是今后勘探的重要领城.而高精度层序地层学研究是寻找岩性地层油藏的主要途径和权威性工具,是促进油气勘探,突破新领城、寻找新目标、确保油田持续稳定发展的重要途径.本文通过建立全区高精度层序地层格架、查明沉积体系及物源、分析构造演化期次及构造地貌坡折对层序、沉积的控制...     

前陆盆地及其对褶皱冲断带构造作用的沉积响应

前陆盆地是研究盆山耦合最理想的场所,同时也是油气资源勘探的主要目标。阐述了前陆盆地的定义和特点,以及其对褶皱逆冲带的沉积响应,指出了可以通过包括不整合面、粗碎屑（砾岩）沉积体、盆地沉降中心迁移、前隆的隆升和迁移、沉积物碎屑组分变化等标识来识别前陆盆地对褶皱冲断带构造作用的沉积响应。     

油气保存单元研究现状及在陆相盆地中的应用

油气保存单元概念产生于南方海相盆地油气勘探研究中,是以独立地质单元整体封闭性能为研究对象,内容涉及到各要素的空间性、时间性、条件性和有效性.级别划分与综合评价是油气保存单元研究的主要方法之一,结合渤海湾盆地东营凹陷博兴洼陷的实际地质特征,首次将油气保存单元的概念和研究方法引入陆相盆地油气勘探中,并将该洼陷划分为12个二级保存单元.通过模糊综合评价,认为 2个整体封闭性好、5个整体封闭性中等、5个整体封闭性差.将整体封闭性不同的保存单元与油气富集程度对比,发现保存单元封闭质量越好,油气富集程度越高.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
