連續出砂 的英文怎麼說
中文拼音 [liánxùchūshā]
連續出砂
英文
continued sand production-
As the increase of domestic high - rise buildings, more and more deep foundation trench supporting constructions have come into existence. among the general geographical condition of the urban district in qingdao, most of regions, which mainly consist of strong de composed rocks, are in quite good condition. except for the sandy soil and oozy soil along sea sides. but the development of rock cracks and breaking zones and unstable lamprophyre still exist, so blasting is needed during constructions of foundation trench. blasting have bad influence on the stability of slopes. moreover. the slope - liding has happened for several times, so the engineering project of foundation trench attracts more attention of people
隨著國內高層建築的發展，深基坑支護工程越來越多，綜合青島市區的地質狀況，除海邊有砂性土及淤泥軟土外，大部分地域巖土條件相對較好，多以強風化巖為主，但巖石裂隙發育，間或有斷裂帶和穩定性極差的煌斑巖穿插其中，基坑施工時需要爆破施工，對邊坡的穩定造成了不利影響，加之連續出現的幾次滑坡失穩事件，基坑支護工程越來越引起了各方面的重視。This thesis investigated and researched on non - loaded crack, especially those caused by thermal - shrink, and analyzed the thermal - shrink stress of beam, slab and continuous - wall, found that according data of civil and overseas offered thermal - shrink calculating formula without considering effect of factors, such as the cement quantity, using of aruhuesiru, aggregate size and quantity of sand, which made the result data smaller. in addition, there are not enough construct measure in code
本文對非荷載裂縫，特別是溫度?收縮裂縫進行了調查研究，並對兩端或四周約束的梁、板和底部約束的地下連續墻進行了收縮應力分析，發現國內外有關文獻給出的收縮計算公式沒有考慮泵送商品混凝土的水泥用量、外加劑使用、骨料粒徑和砂用量等因素的影響，計算出的混凝土收縮量往往偏小；另外， 《規范》中針對溫度?收縮裂縫的構造措施不足。Since the hardened - slurry is a new kind of construction material, the paper undertook some experiments to find a proper way to optimize its performance. the author think that sand but not mortar can improve the fluidity of the hardened - slurry, and the water glass being divided into two partitions can also better the hardened - slurry. in the last partition, the air - agitating method compared with other construction methods is thought to be the proper one in the diaphragm construction, and the optimal agitating - tine is one hour or so
由於固化灰漿是一種新型的地下連續防滲墻墻體材料，為了更好的掌握它，論文對提高固化灰漿的施工性能進行了試驗研究，得出砂以干摻的方式而水玻璃以兩次加入法是使固化灰漿施工性能提高的一種途徑；然後通過模型試驗模擬四種施工方法，比較各種方法的成墻效果，認為氣拌原位攪拌法為較好之法；而氣拌時間對固化灰漿的性能影響試驗則給出了最適宜的攪拌時間是控制在一個小時之內。Based on the geometric features of reservoir, structure and the spatial variation of bore - seepage, this paper carries out the following six aspects : accurate division of exploitation units ; description of continuity of genetic unit ; division of internal structure unit of sand - body ; investigation of flow unit of reservoir ; research of outside - delimited reservoir ; geologic modeling
旨在對其做一個階段性的小結，從儲集層砂體幾何形態、內部結構以及孔、滲空間變化特徵出發，概述了精細地質研究的內容為細化開發單元、成因單元砂體的連續性和連通性描述、砂體內部建築結構單元的劃分、流動單元的研究、表外儲層研究、地質建模等。The case calculation indicates that the radial flow model can reflect the behavior of cold production and sand inflow, be consistent with real situations quantitatively, and prove its reliable property
此外，實例計算還表明，連續出砂確實是出砂冷采提高產量的重要機理之一。The traditional way of sandstone correlation based on the geometrical similarity of well - logs which emphasizes " based on the cycle and correlating from larger to smaller " has shown its theoretical limits when explaining the correlating and the scale, geometry, continuity, connectivity of sandstones and the law of the reservoir property. it has been an urgent and difficult subject to find new theory and methods to solve the reservoir correlation and property prediction. it ' s a new way to correlate strata and found framework of reservoir through the process - response analysis in the base - level cycles
儲層骨架模型是建立儲層地質模型的前提和關鍵，建立在測井曲線相似性基礎上的傳統「旋迴控制，分級對比」原則在進行高含水期精細對比時表現出地層學理論依據不足，在解釋小層段的砂體對比方面，在解釋不同層位砂體規模、形態、砂體連續性、連通性和儲層物性的變化規律方面缺乏有力的理論支撐。The study also shows that continuous sand inflow is indeed one of the most key mechanisms by chop for ior, such as forming highly flowing channels, removing skin effect and improving fluid flowing performance in have oil reservoir
地層連續出砂使得井筒附近形成高滲流通道，解除了表皮污染，改善了油藏中流體的流動特性。分享友人
