  1. As an advanced materials preparation technology, spray - deposition has shown remarkable superiority in producing large - sized alloys and metal matrix composites. however, the spray deposeted preforms usually contain a certain quantity of porosity. besides, the oxide films on the surface of the particles lead to week metallurgic conjunction between the particles. in order to obtain an ideal structure and performance, the porous preforms need further densifying and plastical forming. in this paper, a new technology named wedge pressing was used to densify spray - deposeted 5a06 aluminium alloy, in which the large deformation can be obtained through the sum - up of local deformation and multi - step small deformation. this method can also solved the problems in traditional processing and greatly decreased the producing cost. what ’ s more, the reserch on the wedge pressing desification rules about the large - sized spray deposeted preforms was significant it was vital not only to the further densification of the prefoums but also to the further research on plastical deforming the research was also benefit to the industrialization an the application of the spray deposeted porous materials

  7. 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,因此預測次生發育帶是尋找油氣聚集帶的關鍵.過對陜甘寧盆地隴東地區延長統次生形成的主控因素分析,認為陜甘寧盆地延長統次生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,為後期油氣運聚提供有利及宿住空間,從現今的勘探結果來看,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育良帶是行之有效的方法
