sublacustrine fan meaning in English
湖底扇
Examples
- Sedimentary characteristics of sublacustrine fan of the interval 6 of yanchang formation of upper triassic in southwestern ordos basin
鄂尔多斯盆地西南部上三叠统长6油层组湖底扇特征 - The sublacustrine fan , as an important deposit in actic region of northern chexi sub - sag , is characterized with both source and reservoir in it and favorable hydrocarbon accumulation conditions
摘要湖底扇是车西洼陷北部陡坡带的一种重要的沉积类型，具有自生、自储的特点，成藏条件优越。 - Member - one of nenjiang group is divided into sa 0 sand - group . the same points of medimentary microfacies types and distribution by developed in many sand groups lies in that they dominate with river delta and shore - shallow lake in west and dominate with deep lake - semi - deep lake and contain gravity flow . the change of sediment scope of each sand - group makes deep lake - semi - deep lake and sublacustrine fan sediment of ga 0 and pu 2 sand - groups not being developed during the lest sediment area , but the deep lake - semi - deep lake and sublacustrine fan sediment during the largest sediment scope of sa 0 is well developed
多数砂组发育的沉积微相类型和分布的共同之处在于，西侧多以河流三角洲和滨浅湖沉积为主，东部以深湖?半深湖为主其中夹有重力流，但由于各砂组沉积范围的变化，造成沉积区最小时期的高0 、葡2砂组深湖?半深湖及湖底扇沉积不发育，而沉积范围最大时期的萨0砂组深湖?半深湖及湖底扇沉积极其发育。 - The most favorable reservoirs of study formatioms in study area are delta river mouth bar sand body and sublacustrine fan sand body . the sublacustrine fan sand body region developed in each sand group and the river mouth bar sand body region developed in gao 5 sand - group are the most favorable regions of developing lithologic traps
研究区研究层段的最有利储层是三角洲河口坝砂体和湖底扇砂体，各砂组发育的湖底扇砂体区和高5砂组发育的河口坝砂体发育区是形成岩性圈闭最有利的场所。 - By viewing the cores in cored wells of the research district , combining with the depositional characters of every sand formation and its relevant marks of log facies , the differentiation and sorting of sedimentary microfacies of sublacustrine fan are described systematically ; the planar and vertical changing rules of sedimentary microfacies are studied on this base ; finally the three - dimensional mode of the sublacustrine fan is established , which provides a certain reference action for similar research work
摘要通过对研究区内取芯井的岩芯观察，结合各砂层组的沉积特征及其相应的测井相标志，系统的描述了湖底扇沉积微相的划分及分类，在此基础上研究沉积微相平面及垂向上变化规律，最终建立了湖底扇的立体模型，为以后的类似的研究工作提供了一定的参考作用。
