    • 摘要: 对酒西盆地下白垩统烃源岩的生烃潜力缺乏系统认识,并对其沉积古环境的认识也存在争议.通过对红柳峡地区下沟组烃源岩的孢粉相和元素地球化学的系统分析,研究烃源岩有机质母质来源、生烃潜力及其沉积古环境特征.结果表明红柳峡地区下沟组发育孢粉相A(植物碎屑—无定形组合),B(无定形组合)和C(植物碎屑组合)3类孢粉相,并且以孢粉相C为主;孢粉有机质整体以陆源高等植物来源的植物碎屑为优势成分,有机质类型主要为Ⅲ型,显示较差的生油潜力,其中下段和上段中的部分层位无定形含量较高,有机质为Ⅱ2型,具有一定的生油潜力;下沟组沉积期为半潮湿—潮湿的气候,且具有晚期逐渐变潮湿的趋势,主要为氧化且生产力较低的微咸水—咸水环境,仅下段和上段中的部分层段表现为较深水的贫氧—缺氧沉积环境;红柳峡地区下沟组以近源冲积扇—三角洲和滨浅湖亚相沉积为主,其中早期和晚期沉积期水体稳定,发育部分较好的烃源岩,中期则发育近源氧化的三角洲—滨浅湖亚相沉积和较差的烃源岩.

    • 摘要: 通过卫星影像解译、差分GPS测量和地貌年代学样品采集,对位于酒西盆地内部的阴洼山断裂和新民堡断裂晚第四纪滑动速率进行了研究.阴洼山断裂发育于阴洼山东侧,总体走向315 °,长约25 km;新民堡断裂整体走向300°,长约20 km,二者皆为全新世活动的逆断层.通过野外考察,选择典型断错地貌进行断层陡坎测量,结合所获相应地貌面的年代数据,得到阴洼山断裂和新民堡断裂晚第四纪垂直滑动速率分别为(0.08±0.02) mm/a和(0.11 ±0.02) mm/a.结合断裂倾角及前人研究资料,得到垂直祁连山方向酒西盆地内部断裂的地壳缩短速率约为l mm/a,整个盆地地壳缩短速率约为2.4 mm/a.

    • 摘要: 酒西盆地老君庙构造渐新统白杨河组间泉子段储层具有含水率高、驱油效率低的特点,明确储层孔隙结构特征成为提高油气采收率的关键.综合应用铸体薄片观察、扫描电镜分析、毛管压力测试等方法,对老君庙构造白杨河组间泉子段碎屑岩储层的孔隙结构特征及影响因素进行了研究.结果表明:储层岩性主要为岩屑砂岩和长石岩屑砂岩,具有岩屑含量高、成分成熟度和结构成熟度均低的特征;储集空间以残余粒间孔、粒间溶孔为主;按孔隙结构特征将储层分为4类,其中Ⅰ和Ⅱ类储层物性相对较好,渗透率均大于10 mD,毛管压力曲线有明显平台,偏粗歪度;孔隙结构特征参数中反映孔喉集中程度和粗喉道所占比例的参数与物性有较好的正相关关系;间泉子段L层为碱性成岩环境,粒间有较多的黏土矿物和方解石胶结物,局部胶结作用较弱的井段物性较好,M层酸性成岩环境抑制了胶结作用,使部分原生孔隙得以保存,同时酸性流体的溶蚀作用促进了M层优质储层的形成.研究结果可为油田后期有效开发提供地质依据.

    • 摘要: 甘肃酒西盆地青西凹陷下白垩统下沟组广泛发育的暗色纹层状细粒岩,以其富含铁白云石、钠长石、重晶石、方沸石、黄铁矿和有机质,局部含有微量萤石、透闪石、石盐和呈碎屑状、浸染状产出的微量闪锌矿、黄铜矿、方铅矿等矿物组分吸引着众多沉积地质学家和石油地质学家的高度关注.在以往的研究中,大多数研究者认为此类细粒岩的成因与火山活动有关,将其确定为火山物质蚀变作用的产物.通过地质背景、物质组分、岩石结构构造、包裹体和地球化学特征的研究,提出此类细粒岩属于新型的湖相“白烟型”喷流岩,可识别出6种热水矿物组合、3种主要结构类型和4种常见的原生沉积构造.6种热水矿物组合包括:Ⅰ钠长石—铁白云石(或铁白云石—钠长石)组合,Ⅱ重晶石—钠长石—铁白云石组合,Ⅲ石英—重晶石—钠长石—铁白云石组合,Ⅳ石英—方沸石—钠长石—铁白云石组合,Ⅴ地开石—铁白云石组合,Ⅵ单一铁白云石组合.3种主要结构类型包括:①泥晶—微晶结构,②内碎屑结构,③石盐假晶结构.4种常见的原生沉积构造包括:i纹层状和条带状构造,ii网脉状充填构造,iii旋涡状喷管结构,iv同生变形层理结构.在物质组分和岩石结构分析的基础上,划分出网脉状充填型、水爆型、盆地沉积型和区域扩散型4种喷流岩产状类型,建立了下沟组湖相喷流岩分带性沉积模式,探讨了喷流岩研究意义.%The widely developed laminated,fine-grained sedimentary rocks of the Lower Cretaceous Xiagou Formation in Qingxi sag of Jiuxi Basin,Gansu Province are rich in ankerite,albites,barites,zeolites and pyrites,and are poor in fluorites,tremolites,halites and clastic chalcopyrites,galenas and sphalerite.The hydrothermal minerals and favorable hydrocarbon conditions have been attracting the attention of many sedimentary geologists and petroleum geologists.In previous studies,most geologists believed that these fine-grained sedimentary rocks were associated with the volcanic activity,or were the products of volcanic material alteration.However,through a systematic study on the geological background,compositions,rock textures,rock structures,inclusions and geochemical features,we believed that these fine-grained sedimentary rocks were the lacustrine white-smoke type exhalative rocks.Six kinds of hydrothermal mineral assemblages were identified,including:Ⅰ albites-ankerites (or ankerites-albites),Ⅱ barites-albites-ankerites,Ⅲ Analcime-albite-ankerites,Ⅳ quartz-albite-ankerites,Ⅴ dickite-ankerites and Ⅵ the single ankerite.Three main types of rock textures were identified,including:① the microcrystalline textures,②the intraclastic structure and ③ the halite pseudocrystal textures.Four common types of primary sedimentary structures were divided,including:① the laminated and banded structures,② the network vein filling structures,③ vortical nozzle structures and ④ the syngenetic deformation bedding structures.On the basis of the rock composition,textures and structures,we have identified four occurrence types of exhalative rocks were identified,including the network vein filling type,the water bursting type,the basin deposition and the regional diffusion type.In addition,we establish the sedimentary model of the lacustrine "white smoke type"exhalative rock was established,and explored the significance of this kind of exhalative rock.

    • 摘要: 探讨酒西盆地古近纪沉积与阿尔金左行走滑断裂的关系.通过对酒西盆地西部红柳峡剖面古近系火烧沟组、白杨河组进行系统的沉积学和年代学分析表明:火烧沟组的砾石成分主要以中-低级变质岩和沉积岩为主,到了白杨河组则转变为以岩浆岩为主;古水流方向主体来自西部-西北部;室内砂岩碎屑鉴定结果显示古近系砂岩的碎屑成分全部落入再旋回造山带物源区;碎屑锆石U-Pb年龄测定结果表现出新元古代和中元古代2个主要的年龄峰值.综合对比酒西盆地周缘的物源区,初步认为阿尔金地体为火烧沟组和白杨河组主要的物源供给区.结合前人对阿尔金左行走滑断裂的研究,表明自渐新世以后阿尔金地体才离开酒西盆地,进一步确定阿尔金断裂带最大左行走滑量>450 km.%Sedimentology and geochronology of Paleogene sequences (including the Huoshaogou and Baiyanghe Formations) in the Hongliuxia section of Jiuxi basin are studied so as to explore the relation between the Paleogene sediments with left strike slip Altyn Tagh fault.It shows that the conglomerates in the formations are mainly composed of low-middle grade metamorphic rocks and sedimentary rocks in the Huoshaogou Formation,and of magmatic rocks in the Baiyanghe Formation.Study of these conglomerates reveals that the main paleocurrents are west and northwest direction.The sandstones from the Huoshaogou and Baiyanghe Formations belong to the recycled orogeny environment based on the Q-F-L diagram.Detrital zircons of the four Eocene sandstones obtained two Precambrian characteristic age populations,Neoproterozoic and Mesoproterozoic.Contrasting with periphery provenance sources,it is showed that the provenance of Huoshaogou Formation was mainly from the Altyn Tagh terrane.On the basis of geochronology data,along with the regional stratigraphic and paleocurrent studies,it is considered that the Altyn Tagh terrane is departed from Jiuxi basin after Oligocene,and the maximum left strike slip for Altyn Tagh fault is over 450 km.

    • 摘要: The Qilian Mountains,as a major orogenic belt in the northeastern margin of the Tibetan plateau,is the forefront of the expansion of the plateau to the northeast,where thrusts and folds dominate tectonic deformation.The Baiyang River starts from the inner Qilian Mountains,flowing northward across various structures,and finally into the Jiuxi Basin.This work focused on exhaustive investigations to the terraces on this river to characterize the Late Quaternary tectonic deformation in this region.The results show that (1)these river terraces on the Baiyang River are segmented,of which multiple levels developed at steep terrains and anticlines in the basin.Bounded by the Niutou Mountains,mainly 2-3 and 4-5 levels of terraces formed in the upper and lower reaches,respectively.(2)The longitudinal profiles along the river suggest a vertical motion rate of the Changma fault as(0.32±0.09) mm/a and crustal shortening rate (0.12±0.09) mm/a.There was no vertical activity since the formation of T5 surface(13ka) on the Hanxia-Dahuanggou fault.At the terrace T5(9ka) on the Laojunmiao anticline,fold uplift amounts(6.55±0.5)m and shortening amounts(3.47±0.5) m,yielding uplift and shortening rates (1.23± 0.81) mm/a and (0.67± 0.44) mm/a,respectively.The Baiyang River anticline began to be active about 300ka with uplift and shortening rates(0.21± 0.02) mm/a and (0.14± 0.03) mm/a,respectively since 170ka.(3) In the Qilian Mountains,there were two different deformation characteristics in response to the expansion of the Tibetan plateau.Shear deformation dominates the inner Qilian Mountains,which is manifested as lateral extrusion of blocks.In the northern margin of Qilian Mountains and Jiuxi Basin,the deformation is dominated by compression,expressing crustal shortening and uplift,and the shortening within the basin accounts about half of the total deformation.%祁连山作为青藏高原东北缘的重要造山带,是高原向NE方向扩展的最前缘,逆冲和褶皱作用是青藏高原向N扩展的重要构造变形方式.白杨河发育于祁连山内部,向N汇入前陆区酒西盆地.因此,可以通过白杨河阶地研究祁连山北缘的变形特征.通过对白杨河阶地的详细调查与测量,得到如下认识:1)白杨河阶地具有流域分段性,在地形陡变带及盆地内白杨河背斜区发育多级阶地.以阶地级数来说,以牛头山为界,上游发育2-3级阶地,下游发育4-5级阶地.2)从白杨河阶地纵剖面获得昌马断裂的垂直活动速率为(0.32±0.09) mm/a,地壳缩短速率为(0.12±0.09)mm/a;旱峡-大黄沟断裂T5形成以来(约13ka)没有垂直活动;老君庙背斜区T5阶地(约9ka)褶皱变形隆升量为(6.55±0.5)m,缩短量为(3.47±0.5)m,隆升速率为(1.23±0.81) mm/a,缩短速率为(0.67±0.44) mm/a;白杨河背斜开始活动时期约为300ka BP,其170ka以来的平均隆升速率约(0.21±0.02) mm/a,缩短速率为(0.14±0.03) mm/a;3)北祁连山地区在响应青藏高原向N扩展的过程中表现出2种不同的变形特征:在祁连山内部以剪切变形为主,表现为块体侧向挤出;而在祁连山北缘地形陡变带和酒西盆地内部以挤压变形为主,表现为地壳缩短和隆起,并且盆地内构造缩短变形量占总变形量的50%左右.

    • 摘要: 酒西盆地位于阿尔金左旋走滑断裂和北祁连断裂相交的三角地区,对研究青藏高原北缘新生代早期构造—沉积演化具有重要意义.通过研究酒西盆地红柳峡剖面和火烧沟剖面始新统火烧沟组砂岩碎屑组分类型、形态及石英阴极发光特征,发现大量岩屑、长石和石英颗粒具有明显的变质岩来源特征,认为火烧沟组物源为变质岩.结合酒西盆地地质构造背景及盆地NW向古水流特征,通过系统分析该盆地周缘可提供物源的高点(阿尔金山、祁连山)区域岩性特征,认为酒西盆地火烧沟组物源来自阿尔金山,推测阿尔金左旋走滑断裂的断距应>450 km.
