  3. The variations in trace element contents and ratios may hold up a mirror to the lake - level fluctuations and climatic changes, which, in turn, have exerted a direct and important effect on the sequence stratigraphic development. collectively, the reservoir rocks from the yanchang formation consist dominantly of the delta front subfacies subaqueous distributary channel and channel - mouth bar microfacies and delta plain subfacies subaerial distributary channel microfacies fine - grained feldspar sandstones and siltstones. the reservoir rocks have been subjected to three stages of diagenetic and porosity evolution : ( 1 ) the porosity reduction by the mechanical compaction and chemical pressure solution during the early diagenetic stage ; ( 2 ) the porosity increase by the dissolution during the a substage of the late diagenetic stage, and ( 3 ) the porosity reduction by the cementation and filling during the b substage of the late diagenetic stage

  4. Because during the sedimentation of the flood plain - estuary fades, the conditions of sea level rising, tidal regime, sediment supply and accommodation space were suitable for the development of a tidal ridge system, the sand lenses associated with this facies may represent tidal ridge formation in the incised valley

    在河漫灘河口灣相沉積期問,由於海平面上升、潮流體系、沉積物供給和可容空間條件適合一個潮流沙脊體系的發育,其中的砂質透鏡體可能代表了下切河谷內發育的潮流沙脊。

  6. Relationship between the formation of groundwater and the evolution of regional hydrologic cycle in north china plain

    華北平原地下水形成與區域水文循環演化的關系
  7. The depositional character of zhuxiang formation in the basin reads as follows : a series of nne alluvial fan were formed along the fault. the half - deep lake to deep lake faces appeared by west side of the fault, towards the west the saucer lake faces, shore deposit and flood plain face appeared in proper order. the depositional center of lower cretaceous was formed in eastern part of the basin, and the depositional depth was pinch - out and thinning out from the east to the west

    盆地內下白堊統朱巷組沉積特徵表現為:沿郯廬斷裂帶呈北北東向廣泛發育了沖積扇體系,從近斷裂帶西側出現的半深湖-深湖相,向西依次為濱淺湖相到泛濫平原相的規律性分佈,沉積厚度由東向西尖滅、超覆,構成了明顯的東斷西超的盆地構造格局,表明下白堊統的沉積中心依然位於盆地東部。
  8. Sequence stratigraphy can contribute directly to the exploration of subtle traps. it is effective to increase the precision of stratigraphic correlation, therefor to enhance the reliability of subtle traps prediction, stratigraphic correlation approaches using in this paper based on principle of stratigraphic base - level cycles developed by t. a. cross, which are well tested in shallow marine and coastal plain strata. utilizing core, drilling, logging, seismic data and other information, the paper focus on recognizing the stratigraphic cycles formed by multi - order base - level cycles, establishing the stratigraphic correlation framework, researching on the distribution of reservoir and the prediction of the prospecting targets of the fourth section of shahejie formation in qi - shu area, liaohe basin

    本文以t . a . cross成因地層研究小組提出的以地層基準面旋迴原理為理論基礎進行成因地層分析和儲層預測的高解析度層序地層學為指導,利用鉆井、地震、巖心等多種分析資料,對遼河盆地西斜坡中部齊?曙地區沙四段地層進行了層序地層綜合研究,建立了研究區高解析度等時地層格架,在等時格架內對本區沙四段進行了沉積體系特徵及其展布規律的研究,在綜合分析成藏要素的基礎上對沙四段有利目標區進行了預測。
