背凹區
英文
impressed area-
The study area is composed of sandstone & conglomerate reservoir of alluvial fan & fan delta, which belong to sha3 lower member and sha4 upper member of lower tertiary of yong " an town oilfield in dongying depression. the target stataum develops in the hanging wall of the synsedimentary fault in the scarp zone of dongying depression. the frequently intense movements result in the variation of sandstone and conglomerate reservoir and the evolution of the time and space of sha3 lower member and sha4 upper member in yong " an town oilfield
研究區是東營凹陷永安鎮油田沙三下段、沙四上段的沖積扇和扇三角洲砂礫巖體，目的層發育在東營凹陷陡坡帶同生斷層的下降盤，因斷層多期強烈活動，導致永安鎮油田沙三下段、沙四上段的砂礫巖體成因類型多，時空演化變化大，在扇根一帶小層對比難度大，給油田開發帶來很大的難題，在這種背景下進行流動單元研究難度更大。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
詳細的沉積相研究發現，紅獅地區第三系發育有沖積扇、水下沖積扇、河流、三角洲、扇三角洲、湖泊和湖底扇7種主要沉積相類型，並對作為區內主要勘探目的層系的下乾柴溝組和上乾柴溝組進行了以超層序為單位的沉積相平面編圖，以較高的時間解析度揭示了區內沉積相帶的平面展布及其在不同構造背景中的分佈規律，比如在北部的凹陷陡坡背景下，上升半旋迴低水位期通常發育有水下扇、湖底扇等陡岸近源特徵的沉積體系，下降半旋迴高水位期，扇三角洲相粗碎屑巖由北向南進積;在南部的凹陷緩坡背景下，上升半旋迴主要發育辮狀河流相，下降半旋迴辮狀河三角洲相由南向北進積;而中部紅柳泉一獅子溝一帶則為湖泊相沉積和鹽類沉積。7. it is indicated the prospects for exploration are beidagang bueried - hill - drape - lik fold oil accumulation belt, baidong structure belt and chengbei fault step oil accumulation belt, which directs the explorations of neogene in qikou depression
7 、指出了有利的勘探區帶是北大港潛山?披覆背斜油氣聚集帶、白東構造帶和埕北斷階式油氣聚集帶，為歧口凹陷上第三系的勘探明確了實施方向。5. by summarizing the distribution regularity of existing oil & gas fields, it is found that all kinds of oil & gas reservoirs are distributed around the qikou depression like rings, which are divided into inner ring oil - bearing belt, infer ring oil - bearing belt and outer ring. the inner ring is central of oil - bearing region in qikou depression, which is controlled by haihe faults and qidong faults. the inter ring is in regions which are prospect for oil and regions with paleogeographic background of low - gradient slogze. the outer ring is regions. which are outside the oil - bearing region and inside the oil & gas migration region, with paleogeographic background of buried - hill and faults controlling the basin, ect
5 、通過對已知油氣藏分佈規律的總結，發現各類油氣藏圍繞歧口凹陷生油中心呈環帶狀分佈，分為內環、中環、外環三個含油帶。內環為海河斷裂和歧東斷裂控制的歧口凹陷生油中心區，中環為有利生油區范圍內和緩坡古背景上的地區，外環為生油區范圍以外、油氣側向運移范圍以內的以古潛山為背景或控盆斷裂帶等區域。This paper studies cretaceous volcanics distribution, rock types, tectonic setting and reservoir characteristics in the western depression of liaohe fault depression through statistics of compound logging data, core observation, thin section identification, cathodeluiminescence, scanning electron microscope, x - ray diffraction analysis, image analysis, rock chemical analysis, isotope age testing, and inclusions temperature testing
摘要通過全區綜合錄井資料的統計、大量的巖心觀察，並利用薄片鑒定、陰極發光、掃描電鏡、 x衍射分析、圖像分析、巖石化學分析、同位素年齡測定、包裹體溫度測定等10餘種方法，對遼河斷陷西部凹陷白堊紀火山巖分佈、巖石類型、巖石系列、形成的構造背景及儲層特徵進行了研究。Controlled by the structural sedimentary setting, a set of strata from palaeozoic to quaternary has been deposited in beir depression
在區域性構造沉積背景控制下，貝爾凹陷沉積了古生界至第四系的一系列地層。分享友人
