The south part was slope and deep floor of the lake, and the north part was a broad shallow - water platform of the latchstring shore. in the north part, chang - 6 and chang - 7 oil - bearing beds of yanchang formation were typical shallow - water platform delta with an incomplete progradational sequence, in which the delta plain facies were well developed and the river - mouth bars were not developed
受沉積基底地形的嚴格控制,發育于淺水臺地背景上的延長組長7 ?長6油層組表現出典型的淺水三角洲沉積特徵,具有發育的三角洲平原沉積,而前緣河口壩不發育,剖面上難以形成完整的進積序列。 -
Water shutoff agent dsz - a is composed of inorganic particle. its specialities are low cost, easily flow, high strength and long valid period. the agent suits non - selective water shutoff in sand formation. dsz - a not only can plug high water - bearing formation, but also can plug case leakage. dsz - a has been applied on site and gotten good effect. it is a agent which has wide prospect
井下護泵除砂裝置主要用於產液氣量高,出砂能力大,利用常規裝置、常規方法很難治理的井.它的設計是建立在丟手封隔器卡封的基礎上,將液體攜砂能力由地層進入泵管轉變為先過濾(雙層激光割縫篩管部分) ,再在除砂器內靜態沉澱、由單流閥排入井底等一系列除砂護泵優點.本文著重介紹了井下護泵除砂裝置的工作原理與應用情況 -
Chang - 6 oil - bearing beds, one of the most important oil - bearing beds in yanchang formation, is a set of progradational deposits, which is formed by rivers pouring into the shallow - water platform of the lake after the greatest transgression in chang - 7 stage
作為陜北延長組主力油層之一的長6油層組,是在長7最大湖進之後形成的淺水三角洲背景下,山河流注入充填而成的一套水退型沉積。 -
Of the various kinds of prospecting work, the hydrogeologic work should be mainly carried out in following aspects : division of hydrogeological units, the determination of artesian water - bearing system and the identification of prospecting target horizon ; the analysis on hydrodynamic regime, the analysis on hydrogeochemical environments, the paleo - hydrogeologic analysis and the delineation of redox front and favourable area for uranium ore - formation
其中水文地質工作著重從以下幾個方面來進行:水文地質單元劃分;承壓含水系統和目的層的確定;水動力條件分析;水文地球化學環境分析;古水文地質分析;氧化還原帶和成礦有利地段的圈定。 -
Based on abundant statistic data and photographs of seeping - type uranium deposits at the southern margin of ili basin, detailed description is given of the oxidation - migration of organic matter during seeping of oxygen - bearing water, secondary alteration of minerals, and concentration of uranium and associated elements on geochemical reduction barriers as well as formation of secondary seeping uranium deposits
摘要採用伊犁盆地南緣滲入鈾礦床中的大量統計數據、圖片等資料,論述了在層間滲入型鈾礦床中,有機質在含氧滲流水作用下,發生氧化遷移,巖石中的礦物次生蝕變,並在地球化學還原障上產生鈾及伴生元素的富集,形成後生滲入鈾礦床的過程。 -
The paper has presented a physical oil production technology by artificial earthquake, that is, vibration waves are caused in the oil - bearing formation, resulting in a series of vibration effects, there - fore, oil productivity or water injectivity is increased
摘要人工地震採油是通過地面可調頻振源進行一定頻率的振動,產生振動波,在油層發生一系列的波動效應,達到增產增注目的的一項物理法採油技術。
