其次，分析了覆蓋件成形的特點和要求，同時詳細介紹了影響覆蓋件成形的因素如沖壓方向、工藝補充面和壓料面、凸凹模圓角、拉延筋、壓邊力、坯料尺寸和工藝切口等，並用數值模擬軟體對多個典型的汽車覆蓋件汽車后側圍板、后燈座以及轎車后備箱蓋的沖壓成形情況進行模擬，用模擬結果優化拉延工藝方案，比較了內覆蓋件和外覆蓋件在成形特點和要求的一些異同點，以及常見的起皺、拉裂和回彈、成形不足等缺陷的產生機理和相應對策，重點介紹工藝補充面和壓料面的設計及優化方法，因為拉延是沖壓工藝的關鍵工序，而工藝補充面和壓料面的設計是拉延工序的關鍵，對消除缺陷至關重要。In this paper, the requirements of oil - bearing rock, reservoir and caprock, which formed the neogene reservoir in qikou depression are analyzed. the geological actions and process which are imperative and indispensable to form the reservoir in neogene, are systematicly studied
本文對歧口凹陷上第三系油氣藏形成的生儲蓋層條件進行分析，系統研究了形成上第三系油氣藏所必不可少又相互關聯的地質作用和過程，明確了其富集分佈規律，指明了勘探方向。With an area of 5300 km2, dongpu depression is located in the southwest of lin - qing depression, bohaiwan basin, bounded with lu - xi uplift by lan - liao fault in the east, with nei - huang uplift by chang - yuan fault in the west, with lan - kao heave by the north feng - qiu fault in the south, with xin country depression by ma - ling fault in the north, while spreading along nne defection, taking on the forms of being wide in the south, and narrow in the north. it is a rift fault depression basin with the characteristics of striking, with the basement being the paleozoic and mesozoic, and the capping beds being the cenozoic
東濮凹陷位於渤海灣盆地臨清坳陷西南端，東側以蘭聊斷裂為界與魯西隆起為鄰，西側以長垣斷裂為界與內黃隆起相接，南以封丘北斷層為界與與蘭考凸起相鄰，北以馬陵斷層為界與與莘縣凹陷相望，是以古?中生界為基底，以新生界為蓋層，古近紀形成的拉分走滑?裂谷型箕狀斷陷盆地。From the dongying formation ( ed ) to neogene, the shahejie formation was located in the late diagenetic stage a1 ~ a2 ; the oil and gas pools formed in a wide scale. at present the lower e2s3, with overmatured source rocks and low porosity reservoir rocks, gets into the late diagenetic stage b - c in the northern qibei sag where is not favorable for petroleum accumulation, but the others of the shahejie formation are locate still in the late diagenetic stage a1 - a2 and propitious to form oil and gas pools based on the diagenetic numerical modeling under the condition of overpressure, we build a multiple unit cubic equation model for porosity prediction, as the result of the application of qibei sag, the prediction error is less than 2 %, and the precision excess that of foreign same model
歧北凹陷的模擬結果表明，在沙河街組沉積末沙河街組三段就進入晚成巖階段a _ 1期，油氣藏開始形成；在東營組沉積時期晚第三紀，沙河街組大部分地層處于晚成巖階段a _ 1 a _ 2期，生、儲、蓋層發育，是其主要成藏期；現今在歧北凹陷北部沙三段下部進入晚成巖階段b c期，儲層物性較差、不利於成藏，其他層段仍處于晚成巖階段a _ 1 a _ 2期，有利於油氣藏的形成。Referring to the formation process of qd, it is accepted that there formed a groove around the dot during the formation process due to mass - transfer. when the dots were capped by a compound with larger band gap, there will appear a potential maximum due to larger confinement. the maximum will prevent the carriers from entering the dot, and the origin of the kink point is resulted from the prevention
根據s - k模式量子點的形成過程，我們認為在點的形成過程中由於質量遷移會在點的周圍形成一個凹槽，加上覆蓋層后，由於大的量子限域效應該處將形成一個勢能極大值，該勢能極大值將阻礙載流子從勢壘層向量子點的注入，該過程是導致上述拐點出現的原因。An open, generally shallow concave container for holding or serving food
碟，盤一種無遮蓋的、通常是淺的凹形容器，用來盛或上飯菜The conditions of source rocks, reservoir rocks, and cap rocks are favorable in the southern segment of western sag of liaohe oilfield, where several favorable reservoir - cap rock associations come into being
摘要遼河西部凹陷南段烴源巖、儲集巖和蓋層條件十分優越，形成多套有利的儲蓋組合。Based on the research into sedimentary microfacies, source rocks and associations of source rock, reservoir rock and caprock, the paper discusses the formation mechanism of thick oil in detail and summarizes the transportation and accumulation regular of oil - gas in study area
