次生孔隙
Examples
- 2 . reservoir study shows there have been primary and secondary reserving pores developed in the volcanic rock reservoirs of this area , the secondary pore being dominant
储层研究表明，本区火山岩储层主要发育原生和次生两种储集空间，以次生储集空间为主。 - The diageneses which are destructive to the reservoirs are mainly the filling of minerals in secondary pores , the fissures and the dissolved caverns
对储层起到破坏作用的主要是充填作用，表现为次生溶蚀孔隙、裂缝、溶洞中充填自生矿物，它们的包裹体测温数据证明充填作用发生在埋藏时期。 - The preserved average porosity is 10 . 1 % at present . the main reservoir space of chang 4 + 52 ~ chang 62 sandstone in the area is secondary pores , especially the secondary intergranular pores
研究区储层砂体的储集空间以次生孔隙为主，并以次生粒间孔隙占优势，次为填隙物内溶孔、粒内溶孔。 - 4 ) the main reservoir of studying region is low pority , low peremeability litharenite and feldspar litharenite with the character of the low component maiturity and middle textural maturity . mostly the reservoir space is secondary pore
研究区储层主要为低孔低渗的岩屑砂岩和长石岩屑砂岩，成分成熟度低，结构成熟度中等。 - 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:陕甘宁盆地三叠系延长统是国内外典型的低渗特低渗油田，储集层主要为三角洲砂体，压实作用和胶结作用强烈，储层非均质性非常严重，因此预测次生孔隙发育带是寻找油气聚集带的关键.通过对陕甘宁盆地陇东地区延长统次生孔隙形成的主控因素分析，认为陕甘宁盆地延长统次生孔隙的形成除了受沉积有利相带控制外，还与地层异常压力的作用密切相关.研究认为陇东地区异常压力的形成机理主要由于成岩过程中粘土矿物脱水作用.粘土矿物大量脱水时间正好与有机质脱羧期相一致，从而在异常压力作用下将生油岩中的大量有机酸及co2带到与之相邻的储集层中，并沿着有利储集相带运移，在酸性水经过的地方形成大量的次生孔隙，为后期油气运聚提供有利通道及宿住空间，从现今的勘探结果来看，通过研究地层异常压力纵横向分布特征，并结合有利相带研究预测次生孔隙育良带是行之有效的方法
