Under the guidance of theories of sedimentology, petroleum geology and sequence stratigraphy, and through the comprehensive analysis of outcropsrock, cores, well logs and testing outcomes of rock gas, this paper studies the depositional systems of neopaleozoic and the character of aeration zone in tabamiao area of ordos basin. the result indicates that the object layers are divided into two depositional systems, the barrier seacoast depositional systems are recognized on upper carboniferous taiyuan phase with tidal flat, lagoon and barrier bar sedimentary deposit
本文根據沉積學、石油地質學和層序地層學理論，綜合利用地表露頭、鉆井巖芯、測井曲線資料和試氣成果資料，對鄂爾多斯盆地塔巴廟區塊晚古生代沉積體系及含氣層特徵進行了研究。結果表明，研究區內目的層段可以劃分為2個沉積體系： （ 1 ）上石炭統太原期為有障壁海岸沉積體系，發育潮坪?瀉湖?障壁砂壩沉積。From sedimentology symbol such as rock assembled, sediment gradus, sandstone grading analysis, protogene sedimentary structure, ichnofossile and logging facies etc and palaeoenvironment background, it is confirmed that shen84 - an12block s34 segment is braid river delta system, not fan delta system ( abrupt slope ). then it can be more partition as braid river delta plain sedimentary assembled, delta front sedimentary assembled and prodelta sedimentary assembled on core and log assembled. and delta plain sedimentary assembled can be identified four microfacies : braided distributary channel, crevasse splay, overbank deposits and interdistributary bay
沉積微相研究是儲層非均質性研究的基礎，研究區有豐富的巖芯資料和測井資料，通過巖石組合、沉積韻律，砂巖粒度分析、沉積構造、古生物遺跡和測井相等沉積學標志，結合古環境背景，確定沈84 ?安12塊s _ 3 ~ 4段為辮狀河三角洲體系，而不是前人所認為的扇三角洲（陡坡型）體系，在巖芯和測井組合上可進一步劃分為辮狀河三角洲平原沉積組合、三角洲前緣沉積組合和前三角洲沉積組合，其中三角洲平原沉積組合又可識別出辮狀分流河道、決口扇、分流河道邊部和分流間灣四種微相類型；三角洲前緣沉積組合識別出水下分流河道、水下分流河道邊部和分流河口壩三種微相。Sediment and soil were removed to expose the bedrock and enable the dams to be erected on solid rock. the cofferdams were retained, and the seaward one served as a protective structure. the seawardside of the cofferdam for the east dam was placed with more than 7, 000 dolosses, each weighting 25 tonnes to stop the pounding ocean waves
堤壩建成后，圍堰仍然保留，用作主壩的護堤，西壩的護堤，向海的一面更安放了七千多塊每塊各重25噸的防波石，阻擋來自南中國海及太平洋海浪的沖擊。In this thesis, first, reasons and factors for the stability of loose rock dams were summarized according to the field surveys and certain expert ' s experiences. then, researches on block stability problems were reviewed, and according to the relationship between grain size and incipient velocity, it is found that the block weight is in direct proportion to 6 - 9 power of incipient velocity, and 50 % increase of the velocity will result in about 40 times change of the block weight. after that, experiments were conducted in a flume, focusing on the relationship between incipient velocity and some main factors including block weight, water depth over the dam, cross - section size, block material and river bed material
本文首先根據散拋石壩損毀情況的現場調查資料，結合有關專家多年的整治經驗，總結出壩體的損毀原因及影響因素；對現有塊體穩定性的研究成果進行回顧和總結，並針對散拋石壩的直接損毀現象，結合山區河流的水流、地形特點，利用塊體粒徑與起動流速的關系，提出塊體穩定重量與起動流速高次方成正比的概念，流速50的增長可能導致塊體穩定重量接近40倍的變化；通過二維變坡水槽試驗，研究了壩體穩定的主要影響因素，包括塊體重量、壩頂水深、斷面尺寸、塊體材料（塊石和卵石兩種） 、護底等，結果表明對于山區河流，試圖僅僅通過增加壩體單個塊體重量或斷面尺寸來提高壩體穩定性效果甚微；最後，根據西部地區的自然、經濟、交通等條件，提出可以採用柔性混凝土鉸鏈體等一類整體性較好的護面層作為散拋石壩的防沖毀措施，以期取得良好的工程效果。( 2 ) the most favorable region of gas formation lays inside of the shizhu synclinore and in the west of fangdou mountain block. the secondary favorable region is from zichuya region to longjuba region. the adverse region lays qiyue mountain structure including west of it and fangdou mountain structure
