中文拼音 [bàkǒuhú]
壩口湖
英文
bar lake-
The yanchang formation is divided, for the first time, into six third - order sequences, each with an average time duration of about 4. 5 ma. the single sequence is composed of deltaic and lacustrine sandstones, siltstones and mudstones. the subaerial and subaqueous distributary channel and channel - mouth bar sandstone reservoirs are well developed mainly in the lowstand and highland systems tracts
論文在富縣探區首次應用陸相層序地層學的觀點和方法,把延長組劃分為6個三級層序,平均時限4 . 5ma ,各層序由三角洲與湖泊相砂、泥巖沉積組成,主要在低位體系域和高位體系域發育水下(上)分流河道和河口砂壩砂巖儲層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。Depending on the above studies, the following conclusions can be obtained : 1 ) chang - 6 oil reservoir set of panguliang is a set of continental clastic sediment composed of lacustrine and deltaic system in which estuarine bar is not well developed
研究結果認為:靖安油田盤古梁油藏長6油層組屬于以水下分流河道為主的具有強烈的進積作用,以水下分流河道為骨架砂體,河口砂壩不很發育的河控型湖泊?三角洲體沉積,主要發育三角洲前緣相。According to observing the core and well logging facies analysis, yanchang 4 + 5 sector to yangchang 3 mainly developed underwater distributary channel, river mouth bars, underwater natural levee, underwater crevasse splay, interdistributary bay, far bars, etc. and some shallow lake subfacies
根據巖芯觀察以及測井相分析,認為長4 + 5 ?長3期以水下分流河道、河口砂壩、水下天然堤、水下決口扇、分流間灣和遠砂壩等沉積微相以及部分淺湖亞相沉積為主。They are skeletal sand bodies in system of delta and places of most reservoir distribution. the diagenetic processes that govern reservoir properties include the extent of compaction, cementation and dissolution of grains. we recognize that at the early diagenesis phase, mechanical and chemical compaction is very strong, which reduced the original porosity
河口砂壩多位於分流河道或次一級分流河道河口部位,向湖盆中心呈放射狀分佈,因而河口砂壩砂體多構成朵狀砂體,覆蓋面積大、連片好,砂體厚度大,是本區已知油藏主要分佈區。Yanchang 4 + 5 sector to yanchang 3 sector lithofacies palaeogeography pattern was stable, because the constitution background was steady, and the source direction had no change, and supply was abundant. in those sectors the basin development was in lake retreat, and in the period of extinction gradually, and formatted construction delta deposit, but in yanchang 33 period the sedimentary speed were greater than construction speed, showing that overriding river mouth bars were abundant
長4 + 5 ?長3期湖盆發展處于湖退、萎縮逐漸消亡時期,由於構造背景穩定,物源來源方向沒有變化,物源供給充分,所以巖相古地理格局基本一致,形成建設性三角洲沉積,但長3 ~ 3期沉積速率大於構造沉降速率,表現為疊置河口砂壩極其發育。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
研究區研究層段的最有利儲層是三角洲河口壩砂體和湖底扇砂體,各砂組發育的湖底扇砂體區和高5砂組發育的河口壩砂體發育區是形成巖性圈閉最有利的場所。And the fluvial genetic unit includes point bar, the bottom of channel, bursted fan, bursted channel, natural bank, over - bank deposits, small lake of flooding plain and swamp and so on
成因相包括點壩、河道底部沉積、決口扇及決口河道、天然堤及越岸沉積、泛濫平原小型湖及沼澤等。分享友人
