overbank
解釋
大坡度轉彎-
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。 -
With the research object of overbank soft clay near the yiluo river, by means of pack drain to accelerate the consolidation of the soft ground and analysis of fourteen selected representative observation section, in the same time with the help of such testing apparatus as settlement plates, deflection inclinometer, piezometer, telescoping tube, my study not only evaluate the effect of pack drain ' s quickening up the consolidation of soft ground impersonalily and scientifically but also sum up the settlement disciplination of overbank soft clay after more than one years ? observation of settlement and stability continuously
本文以伊洛河河灘相軟土為研究對象，利用沉降板、測斜管、孔隙水壓力計、分層沉降標等多種測試儀器，選取14個有代表性的觀測斷面，進行了一年多的沉降與穩定觀測。通過對觀測數據的分析，進而對袋裝砂井加速河灘相軟土固結效果進行了客觀、科學的評價，同時推算了沉降系數m _ s和固結度參數，並對河灘相軟土的沉降規律進行了分析。 -
Those within existing stream channels are much less stable than overbank deposits.
現在河槽內沉積物的穩定性比河漫灘上沉積物差的多。 -
The region and the earth surface across this road are mainly water above ground and run - off and the ground water is mostly made up of groundwater and perched water ; the river bed is more obvious ; the overbank is covered by medium sand and gravel ect
路線所經地帶地面主要為地表水和徑流，地下水主要以潛水和上層滯水為主，河床較明顯，河灘覆蓋中砂、礫石等。地勢低洼地帶地表常年積水，影響路基穩定。 -
Delta front sedimentary assembled can be identified three microfacies : underwater distributary channel, underwater overbank deposits and distributary mouth bar. reservoir heterogeneity can divide macro heterogeneity and micro heterogeneity according to reservoir scale. macro heterogeneity research based on sedimentology and studied on sandstone longitudinal and landscape orientation distributing mode, it ' s inner structure character
儲層非均質性根據儲層描述尺度大小，可區分為宏觀非均質性和微觀非均質性，宏觀非均質性研究是以沉積學為基礎，研究砂體縱橫向分佈模式，砂體內部的結構特徵。
