Besides , the sedimentary facies of upper ganchaigou and lower ganchaigou formation were also mapped in supersequences which are the main target strata for exploration . the high resolution sequence stratigraphic framework showed the genetic relationship between the distributions of sedimentary facies and their tectonic settings . the near - source sedimentary systems such as subaqueous alluvial fan and lake - floor fan are often deposed in rise - hemicycles in the steep slope background in the north , the coarse lithology of fan - delta prograded from north to south in fall - hemicycles , and the braided stream facies are formed in the rise - hemicycles in gentle slope background in the south , braided stream facies prograded from sorth to north in the fall - hemicycles , but the lacustrine facies and salt lake facies developed in the middle part of the area 详细的沉积相研究发现,红狮地区第三系发育有冲积扇、水下冲积扇、河流、三角洲、扇三角洲、湖泊和湖底扇7种主要沉积相类型,并对作为区内主要勘探目的层系的下干柴沟组和上干柴沟组进行了以超层序为单位的沉积相平面编图,以较高的时间分辨率揭示了区内沉积相带的平面展布及其在不同构造背景中的分布规律,比如在北部的凹陷陡坡背景下,上升半旋回低水位期通常发育有水下扇、湖底扇等陡岸近源特征的沉积体系,下降半旋回高水位期,扇三角洲相粗碎屑岩由北向南进积;在南部的凹陷缓坡背景下,上升半旋回主要发育辫状河流相,下降半旋回辫状河三角洲相由南向北进积;而中部红柳泉一狮子沟一带则为湖泊相沉积和盐类沉积。
The lake basin range was widen and the deep lake subfacies developed in the researched area during chang7 stage . the lake basin range contracted when it got to chang6 stage . consequently , the fan deltas , braided deltas , deltas , saucer lake and local deep lake facies developed in the area 长8期主要发育三角洲、扇三角洲及辫状河三角洲,而且以前缘亚相为主;进入长7期,湖盆范围扩大,研究区以深湖相为主;至长6期湖盆范围收缩,研究区发育扇三角洲、辫状河三角洲、三角洲、浅湖和局部的深湖沉积。
The sedimentary facies of the jurassic penglaizhen formation in the studied area can be described as follows : from the edge of the basin , the source of deposition , to the center of the sedimentation are alluvial fan facies fluvial facies fan delta facies delta facies lake facies and lake floor fan facies in turn 研究区侏罗世蓬莱镇期沉积盆地的沉积相类型分布,从盆缘近物源区至盆地沉降-沉积中心区依次为冲积扇、河流相、扇三角洲相、河控三角洲相、湖泊相和湖底扇相等沉积体系。
The border facies did not appear at the south edge of tiaohu seg . in the basin , the braided river facies and braided delta facies were only found at the foot of chahaquan palaeohigh in the west - south edge of the basin , the meandering delta was found from mazhong structural belt to fangfangliang horseback , and the other area were found covered by the shallow and fairly deep lake facies 条湖凹陷南缘芦草沟组未见边缘相沉积;岔哈泉古隆起处见少量辫状河相及辫状河三角洲相沉积;方方梁凸起东部至马中构造带发育曲流河三角洲相;其余地区则均为滨浅?半深湖相沉积。
Based on available data , the study on regional structure , sedimentary reservoir and source rock characteristics shows that the basins in south china sea had experienced sedimentary evolution in faulting period and depression period , deposited thick cenozoic formation , upwardly developed alluvial fan facies , river - lake facies coastal swamp facies coastal facies , neritic facies and bathyal deposit system , regionally had 3 source rocks of eocene , oligocene and miocene , 3 reservoirs of pre - cenozoic basement buried bill , oligocene sandstone and miocene reef , with pliocene and pleistocene neritic facies and bathyal shale as regional caprock 摘要以现有资料为基础,通过对区域构造、沉积储层、烃源岩特征等基础石油地质条件研究,认为南海海域各盆地经历了断陷期和坳陷期沉积演化,沉积了巨厚的新生代地层,自下而上发育了冲积扇相、河湖相、滨岸沼泽相、滨海相、浅海相、半深海相沉积体系,区域上存在始新统、渐新统和中新统3套烃源岩,前新生代基岩潜山、渐新统砂岩、中新统生物礁3套储层,区域盖层为上新统和更新统浅海半深海相泥岩。
Sedimentary facies consist of fan delta , delta , nearshore submarine fan , sublacustrine fan , littoral - shallow lake beach and bar , as well as littoral - shallow lake , and semideep - deep lake facies and subfacies , of which the preferred sedimentary facies include delta , fan delta front , sublacustrine fan , midfan and outer fan of the nearshore submarine fan , and beach - bar facies developed in the littoral - shallow lake 综合考虑物源特徵、沉积环境、沉积体系平面展布以及生、储、盖组合关系,认为有利的沉积相带主要是三角洲、扇三角洲前缘、湖底扇、近岸水下扇的中扇和外扇以及滨浅湖中发育的滩坝和砂坝。
On the east terrace - fault slope of the depression , the sedimentary mode of fan - shaped delta - slump turbid fan - deep lake facies are developed . on the long axial direction of fula depression , the southeastern groove was filled with a large scale delta which was the main sources , the other little delta limited by the 3 syndepositional fault was distributed down the slope edge of the northern sub - depression . this stage developed a favorable oil sources , reservoir and regional seal which formed the good matching relations of generation , reservoir and seal in the time - space zone Abugarbra组的sc和sd层序发育在边界断层和同沉积断层活动剧烈、湖盆扩张期,凹陷中心发育半深湖-深湖相沉积,在凹陷陡坡发育近岸水下扇,断阶缓坡带发育扇三角洲?滑塌浊积扇?深湖相组合,长轴凹槽和北部次凹的北部缓坡带发育三角洲体系,此层位是有利生油层和岩性圈闭发育层段。
