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。And the delta genetic unit includes distributary channel, distributary bay, small lake of delta plain, swamp, distributary estuary bar, frontal delta mud and sandy density flow and so on. the fluvial system is composed of channel, channel side and flooding basin
其成因相包括分流河道、決口扇及決口河道、分流間灣、三角洲平原小型湖、沼澤、分流河口壩、前三角洲泥及砂質重力流等;該區河流體系由河道、河道邊部及泛濫盆地等沉積組合構成。Study achievement appears as following aspects : ( 1 ) yellow river estuary gate river flow and tide flow mixed area is not keep standing deposition status, on special income water and sediment conditions, boundary conditions and oceanic power conditions, this area may on the scour status ; ( 2 ) observed from estuary sediment deposition distributing process : delta and sea offing area sediment deposition vary trend is similar, each part sediment deposition scale varies as wave shape ; ( 3 ) on estuary gate, affect the sediment deposition factors, primary factors are tide prop, the gate widens gradually, estuary gate have branches, brine induced flocculation. this paper study the estuary gate widen, estuary gate have branches to affect the river channel deposition in quantity ; ( 4 ) based on field measured data, for the first time, deduce the estuary sediment deposition and distributing regress formula which can estimate estuary different areas sediment deposition volume ; ( 5 ) this subject demonstrate the estuary delta coastline dynamic balance conception, build the relationship between the estuary income sediment with deposition land area, draw the following important conclusion : when estuary years - averaged income sediment keeps at 345 million tons, the delta coastline may on the dynamic balance status. ( 6 ) this subject firstly brings up estuary sediment optimized control conception, and has the primary study on the macroscopically optimized control conception method
研究認為: ( 1 )黃河河口口門逕流潮汐區域並非持續保持淤積狀態,在特定的來水來沙、邊界條件和海洋動力條件下,該區域可以處于沖刷狀態; ( 2 )從河口泥沙沉積分配的過程來看:三角洲與濱海區泥沙的沉積變化趨勢是基本一致的,各部位的泥沙沉積比例變化基本呈波動狀態,且三角洲與濱海區泥沙的沉積比例與來沙量密切相關,基本成正比關系; ( 3 )在口門處,影響泥沙沉淤的因素主要集中在潮汐頂托、口門逐漸加寬、河口門分汊、鹽水造成絮凝等,本報告主要對口門加寬,口門西妥理工大學工程碩士專業學位論文分漢對河道淤積的影響進行了定量分析: (一扣根據實測資料首次建立了河贖流路泥沙沉積分配的回歸計算式,據此可以預估計算河口不同區域泥沙的沉淤量; 、 5 )本項研究首次論證了河口三角洲岸線動態平衡的概念,並建立了黃河河口來沙量與造陸面積的相關關系,得出了當河口多年平均來沙量維持在3 . 45億t時其河口三角洲岸線則可能處于動態平衡狀態的重要結論; 『 6 )本項研究首次提出了河口泥沙優化調控的概念,並對其宏觀優化調控模式進行了初步探討。And there are three parfacies - - delta plain, delta front and prodelta and eleven microfacies which are distributary channel, channel bar, marginal bank ( point bar ) and so on. the text also discuss the sedimentary characteristic and cross section structure of every microfacies
識別出三角洲平原、三角洲前緣和前三角洲3個亞相及分流河道河床、心灘、邊灘等11個微相類型,並對各微相類型的沉積特徵和剖面結構進行了討論。分享友人
