  1. 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
