The reservoirs of the Upper Triassic Xujiahe Formation in Sichuan Basin have the characteristics of low compositional maturity, low contents of cements and medium textural maturity. The general physical properties of the reservoirs are poor, with low porosity and low permeability, and there are only a few reservoirs with medium porosity and low permeability in local areas. Based on the diagenetic mineral association, a diagenetic sequence of cements is established: early calcites (or micrite siderites) →first quartz overgrowth→chlorite coatings→dissolution of feldspars and debris→chlorite linings→ second quartz overgrowth (quartz widen or filled in remain intergranular pores and solution pores)→dissolution→third quartz overgrowth (quartz filled in intergranular and intragranular solution pores)→intergrowth (ferro) calcites→dolomites→ferro (calcites) dolomites→later dissolution→veins of quartz and calcites formation. Mechanical compaction is the main factor in making the reservoirs tight in the basin, followed by the second and third quartz overgrowth. In a long-term closed system, only feld-spars and some lithic fragments are dissolved by diagenetic fluids, while intergranular cements such as quartz and calcit are not dissolved and thus have little influence on the porosity of the Xujiahe Formation. This is the third factor that may have kept the sandstones of Xujiahe Formation tight finally. The hydrocarbon was extensively generated from organic materials after the second quartz overgrowth, and selectively entered favorable reservoirs to form tight sandstone gas reservoirs.

In view of the difficulties in the study of lithofacies paleogeography and the low reliability of the distribution range of sedimentary sand bodies in the prototype basin caused by less deep drilling, complex seismic imaging and low degree of exploration in the southern margin of Junggar Basin, NW China. A new method based on the source to sink idea was used to restore lithofacies paleogeography and predict glutenite distribution. In the restoration, apatite fission track age was used to define range and uplift time of macro-provenance;the range of provenance area and the migration process of lake shoreline were restored based on the quantitative relationship between gravel diameter and transportation distance, tectonic shortening and other geological parameters;drilling cores and field outcrop sedimentary structures were analyzed, and a series of maps of lithofacies paleogeographic evolution and distribution range of glutenite bodies were compiled. It is concluded that from Early Jurassic to Early Cretaceous, in the southern margin of Junggar Basin, the provenance area gradually expanded from south to north, the lake basin expanded, shrunk and expanded, and the paleoclimate changed from humid to drought to humid. The western section always had proximal fan delta deposits from the southern ancient Tianshan provenance developed, and in the middle and eastern sections, the provenance areas evolved from far source to near source, mainly river-delta, braided delta, fan delta and other sediments developed. The boundary between provenance areas of the western and middle sections is speculated to be Hongche fault zone. In an angle open to the northwest with the current basin edge line, the restored ancient lake shoreline controlled the heterogeneity of reservoirs in the delta plain belt and delta front belt on its both sides. The ancient lake shoreline, current stratigraphic denudation line and current basin margin line limit the types and scope of favorable ***

Based on the data of outcrops, seismic sections, thin sections, heavy mineral assemblages and detrital zircon U-Pb dating, the sedimentary characteristics, lake level fluctuation and provenance characteristics of the Middle Jurassic Lianggaoshan Formation(J_(2)l) in eastern Sichuan Basin, SW China, were investigated to reveal the control of tectonic movements of the surrounding orogenic belts on the sedimentary systems. The J_(2)lmainly developed a delta–lake sedimentary system, which contained a complete third-order sequence that was subdivided into four lake level up-down cycles(fourth-order sequence).The lake basins of cycles Ⅰ and Ⅱ were mainly distributed in eastern Sichuan Basin, while the lake basins of cycles Ⅲ and Ⅳ migrated to central Sichuan Basin, resulting in the significant difference in sedimentary characteristics between the north and the south of eastern Sichuan Basin. The provenance analysis shows that there were three types of provenances for J_(2)l. Specifically, the parent rocks of Type Ⅰ were mainly acidic igneous rocks and from the proximal northern margin of the Yangtze Plate;the parent rocks of Type Ⅱ were intermediate-acid igneous rocks and metamorphic rocks and from the central parts of the southern and northern Qinling orogenic belts;the parent rocks of Type Ⅲ were mainly metamorphic rocks followed by intermediate–acid igneous rocks, and from the North Daba Mountain area. It is recognized from the changes of sedimentary system and provenance characteristics that the sedimentary evolution of J_(2)lin eastern Sichuan Basin was controlled by the tectonic compression of the Qinling orogenic belt. In the early stage, the lake basin was restricted to the east of the study area, and Type Ⅰ provenance was dominant. With the intensifying north-south compression of the Qinling orogenic belt, the lake basin expanded rapidly and migrated northward, and the supply of Type Ⅱ provenance increased. In the middle and late stages, the uplift of the North D

埃迪卡拉纪-寒武纪重要地质历史转折时期全球多陆块广泛沉积硅质岩.塔里木盆地西北缘下寒武统玉尔吐斯组底部所发育的薄层状硅质岩,以富含残余颗粒、磷质结核和重晶石结核而显得非常特殊和罕见,明显有别于国内外报道的常规硅质岩.为了揭示该套硅质岩的成因及沉积模式,通过剖面测量(库勒剖面)、薄片鉴定、SEM观察、能谱探针、主微量元素特征、氧硅同位素分布等岩石学-地球化学分析方法,认为玉尔吐斯组硅质岩垂向上共分5小段,其主要矿物是石英、白云石,自生矿物主要有重晶石、方沸石、黄铁矿等,不同硅质岩段微观结构显示出十分明显的组构变化,包含残余颗粒结构、残余晶粒结构、隐晶质结构和微晶结构.所测剖面硅质岩沉积于靠近大陆/古隆起的高盐度浅海陆架(高Al2O3/(Al2O3+Fe2O3)比值,高MgO/Al2O3比值),其陆源碎屑主要来自大陆地壳或基底花岗岩的风化产物,并且受到SiO2的稀释作用影响(Th/Ti与Al/Ti关系).氧化还原敏感元素(如Ba、V、Ni、Cu、Zn、U等)不同程度的富集及氧化还原指标(V/Cr介于0.81~8.34)特征表明硅质岩段沉积早期处于氧化环境,水体能量较强,显微镜下见圆度较好的内碎屑颗粒、微生物席碎片;中晚期经历了水体循环不畅的有氧/缺氧分层环境(Ce/Ce*负异常),显微镜下微生物球粒、粪球粒、浮游藻(粘结)团块发育,有机质含量较高(TOC可达2%以上).稀土元素特征(低∑REE、中等Ce负异常、显著的Y正异常和Eu正异常)以及δ^30Si和δ^18O值分布范围暗示硅质岩地球化学特征主要继承自热液流体和海水,受陆源碎屑影响较弱.自近台内裂陷中心上升的富含多金属的富硅热液以及陆源碎屑提供大量营养,为微生物大繁盛和硅质的富集成矿奠定物质基础.水体中硅的溶解度降低(温度降低、pH降低和水体盐度升高)促使硅质胶体颗粒化学沉淀,而微生物(特别是嗜热微生物)的新陈代谢活动往往加速了这一过程.

基于5条野外露头剖面、162块薄片、12块扫描电镜(SEM)样品及52套孔渗物性数据等资料,分析塔里木盆地阿克苏地区下寒武统肖尔布拉克组台缘微生物礁的结构特点及储集层主控因素。台缘由小型微生物礁群组成,单一礁体可分为前礁相、礁前相、礁脊相、礁后相,镜下可见礁岩具有不同的显微结构。微生物礁发育微生物结构储集空间和非生物结构储集空间,前者包括窗格孔、格架孔、铸模孔及超大溶孔,后者包括微裂缝和缝合线。孔渗数据统计结果表明:于提希剖面微生物礁孔隙度基本小于5%,渗透率一般小于1.0×10^(-3) μm^2,主要为特低孔特低渗储集层,而苏盖特布拉克剖面孔隙度多为3%~10%,渗透率为(0.1~50.0)×10^(-3) μm^2,整体跨度较大,且礁内物性非均质性较强,主要为低—中孔、低—中渗储集层。说明不同微生物礁的物性特征具有较大的差异,同一微生物礁内亦具有明显的储集非均质性。古地貌特征控制微生物礁的发育,沉积作用控制相带的展布及原生孔隙的发育,而溶蚀作用受控于古地貌特征和沉积作用,最终决定微生物礁储集层孔隙的演化。

库车坳陷白垩系巴什基奇克组大面积厚层状砂体为塔里木油田重要的产气层段,厚层状砂岩的沉积环境研究一直存在争议。在厚层状砂岩中,普遍发育有褐色泥质砾石和少量粉细砂质砾石,明确与厚层砂岩相伴生的砂泥质砾石成因机制与沉积环境,可从全新角度来探讨大面积厚层状砂岩的沉积环境。通过野外露头与多口钻井的岩心观察,分析泥质砾石组成矿物成分及含量,将泥质砾石、粉细砂质砾石按照成分、形态及赋存状态(产状)进行了种类划分。依据砂泥质砾石成分判断其主要来自于厚层砂岩附近褐色粉砂质泥岩,进而采用"将今论古"的方法,发现在现代塔里木河(季节性曲流河)、赣江浅水三角洲上平原—下平原环境中,发育有泥质砾石沉积,并结合前人成果,综合类比分析后认为厚层砂岩中的砂泥质砾石具有同样的成因机制与发育环境。研究表明巴什基奇克组中的泥质砾石、砂质砾石为季节性河流及/或季节性河流浅水三角洲上平原—下平原(受间歇湖水影响区)环境下的产物,即属于处于陆上、间歇有湖水影响的沉积环境下的产物,并非长时期处于"水下"的三角洲前缘—滨浅湖环境下的产物。砂泥质砾石的成因机制为:河道堤岸沙泥质垮塌、原地堆积而成;堤岸沙泥质垮塌后短距离搬运而成。受此启示,认为巴什基奇克组厚层砂岩主要发育于季节性河流以及季节性河流浅水三角洲上平原—下平原的沉积环境。

基于野外露头观察和室内薄片鉴定工作,详细描述了塔里木盆地阿克苏地区下寒武统肖尔布拉克组微生物碳酸盐岩的展布特征,建立了层序地层格架,分析了肖尔布拉克期碳酸盐台地的演化过程。研究认为,肖尔布拉克组可分为两个三级层序:下部层序SQ1整体为一套波状微生物席,处于中-内缓坡沉积环境,对应缓坡型台地发育阶段;上部层序SQ2的海侵期是缓坡型台地向弱镶边台地的转变阶段,斜坡以风暴沉积为主,微生物岩不发育,而高地则以大型进积微生物礁建隆为主,主要通过丛状表附菌的自身骨架生长和微生物粘结方式成隆。高位期是弱镶边台地发育阶段,台缘和台内相分异明显。台缘区早期发育房室状表附菌层,晚期发育小型进积微生物礁群,由微生物粘结成礁,而台内区为低能微生物滩,缺乏高位早期建造,晚期以层纹石建造、泡沫绵层石和叠层石建造为主,其形成与粘性微生物席有关。

针对准噶尔盆地南缘深层钻井少、地震成像复杂、勘探程度低而导致的原型盆地岩相古地理研究困难、沉积砂体展布范围可信度低的问题,基于源-汇思想,使用新方法开展岩相古地理恢复与砂砾岩体分布预测研究,应用磷灰石裂变径迹年龄确定宏观物源区范围与隆升时间;依据砾石径与搬运距离定量关系、构造缩短量等地质参数,恢复物源区范围、湖岸线迁移过程;开展钻井岩心与野外露头沉积构造等分析,编制岩相古地理演化与砂砾岩体分布范围系列图件。早侏罗世—早白垩世,准噶尔盆地南缘物源区范围由南向北逐步扩大,湖盆经历扩张—萎缩—扩张、古气候经历潮湿—干旱—潮湿的演化过程。西段一直发育来自南部古天山物源的近源扇三角洲沉积,中段与东段物源区具有由远源到近源的演化特征,主要发育河流—三角洲、辫状河三角洲、扇三角洲等沉积;西段与中段物源区的分界线推测为红车断裂带。恢复出的古湖岸线与现今盆地边缘线呈向西北敞开的夹角,控制了其两侧三角洲平原相带与前缘相带储集体的非均质性,湖岸线与现今地层剥蚀线、盆地边缘线限定了有利储集体的类型与范围。该认识可为准噶尔盆地南缘深层下组合油气勘探提供地质参数依据。
