By using ncep / ncar reanalysis data of height and wind, the inter - monthly lpac map, the climate lapc map, inter - annual anomaly map and mean variance map of monthly wind field of 850 and 500hpa and monthly height field of 850, 500, 150, 30hpa are calculated in a globe - belt area, which situates between 30 s and 75 n, from december 1957 to december 1997, according them we analysis the rule of the season transfer and anomaly of nh mean circulation. the results show that the climate map of lapc can describe the seasonal transfer process of large scale circulation better. the advance process of summer circulation establish is form south to north at the middle and lower level of the troposphere, that is reflected primly in the inter - monthly wind and pressure map of lapc ; at lower lever of stratosphere, the establish process is simulate to that of troposphere, and reflect of process of that the south asia high toward plateau ; at middle stratosphere the summer circulation establish begins at middle and high latitude initially, and then transmits to low latitude gradually, while the seasonal variability in mid - stratosphere is stronger than it in troposphere and low - stratosphere
利用ncep ncar再分析高度場和風場資料，計算了30 s 75 n球帶區域1957年12月至1997年12月逐月850 、 500hpa風場及850 、 500 、 150 、 30hpa高度場月際局地型相似系數圖、多年平均圖（即氣候lpac圖） 、年際異常圖及均方差圖，在此基礎上，分析了北半球平均環流季節轉換及其異常的規律。分析表明，氣候局地型相似系數圖較好地給出了大尺度環流季節轉換發生的過程：在對流層中、下部，風、壓場月際局地型相似系數圖清楚地反映了夏季型環流建立由南向北的推進過程；低平流層夏季型環流的建立與對流層接近，其中，南亞高壓上高原過程有明顯反映：中平流層，夏季型環流的建立明顯表現為從中、高緯度開始，逐步向低緯傳播的特徵，且變化較對流層和低平流層明顯。 -
Abstract : yanchang series is a typical low permeability reservoir, and its favourable sandstone reservoir is delta facies. heavy compaction, cementation and heterogeneity exist in it. according to the analysis of the main control factors of forming the secondary pore, it is held that the secondary pore in longdong area is controlled by both favorable facies belt and abnormal formation pressure. it is also held that the formation of the abnormal formation pressure is due to the dewatering of the clay mineral during diagenesis because the dewatering time is identical with the decarboxylation time of organism. organic acid and co2 are driven to adjacent favorable reservoirs under the abnormal formation pressure, and a lot of secondary pore is produced in the runners. from the present exploration result, it is useful to predicting the development of secondary pore to study the distribution of abnormal formation pressure
文摘:陜甘寧盆地三疊系延長統是國內外典型的低滲特低滲油田，儲集層主要為三角洲砂體，壓實作用和膠結作用強烈，儲層非均質性非常嚴重，因此預測次生孔隙發育帶是尋找油氣聚集帶的關鍵.通過對陜甘寧盆地隴東地區延長統次生孔隙形成的主控因素分析，認為陜甘寧盆地延長統次生孔隙的形成除了受沉積有利相帶控制外，還與地層異常壓力的作用密切相關.研究認為隴東地區異常壓力的形成機理主要由於成巖過程中粘土礦物脫水作用.粘土礦物大量脫水時間正好與有機質脫羧期相一致，從而在異常壓力作用下將生油巖中的大量有機酸及co2帶到與之相鄰的儲集層中，並沿著有利儲集相帶運移，在酸性水經過的地方形成大量的次生孔隙，為後期油氣運聚提供有利通道及宿住空間，從現今的勘探結果來看，通過研究地層異常壓力縱橫向分佈特徵，並結合有利相帶研究預測次生孔隙育良帶是行之有效的方法 -

Abstract : the forced state in key parts and their lifetime, the volume of high pressure chamber and ratio of pressure, the length of high pressure stroke and pressure stability, the relations between the deformation of high pressure chamber and temperature field and pressure field for three kinds of apparatus of making synthetic diamond under high pressure and high temperature were compared in this paper. the differences of these main apparatus were analyzed according to the degree of difficulty and ease in the technique, the choice of applicability and the cost and yield of them. it was emphasized that studying and developing the large sized belt - type press should be the way to make high quality saw diamond and change the state of making middle and low quality diamond in the diamond industry of our country, catching up with the international advanced level as well
