查询词典 digenesis

The result indicates that all the reservoirs have the characteristics that the mineral maturity is low but the structure maturity is high; the porosity types are primal grain porosity and dissolution porosity est., The physical property is middle pore and low permeability , middle pore and very low permeability; Sedimentary environment, petrology composition and radius, composition and amount, and the digenesis are all the factors that influence the reservoirs.

结果表明：延长组储层具有成分成熟度低而结构成熟度高的特点；孔隙类型主要为粒间孔，溶蚀孔，晶间孔和微裂隙等；属于中孔，低渗型和中孔，特低渗型储层。影响储层物性的主要因素是沉积环境和沉积相，碎屑颗粒成分及粒度，填隙物成分及含量，成岩作用等。该研究对制定油田开发方案和提高油气采收率具有重要意义。

Cathodoluminescence and δ〓O、δ〓C values of the sparites of geopetal structures within fossil brachiopods indicate that the sparcalcites were formed in equilibrium with various stages of postdepositional digenesis or catagenesis with each stage's δ〓O of interstitial water different.

3碳酸盐岩早期成岩胶结物或孔洞充填中的亮晶方解石是除腕足化石外获取碳酸盐岩原始氧、碳同位素组成的又一种常用样品。但本论文研究发现，龙门山地区碳酸盐岩的成岩后生改造具有多期多次现象，不同改造期次的流体之间存在明显的δ〓O差异，但无明显的δ〓C差别。
