黄骅坳陷中北区深部储层物性影响因素分析

通过对黄骅坳陷中北区的研究认为， 影响该地区深部储层物性的因素主要有沉积环境和沉积相、成岩作用和深部地层异常超压的形成与分布等， 其中成岩作用中的胶结作用（ 主要为硅质胶结和铁白云石胶结） 是致使深层孔隙度降低的主要原因， 酸性水的溶解作用是产生大量次生孔隙的重要因素， 深部异常压力带的存在是次生孔隙得以保存的重要条件

FACTORS OF AFFECTING THE RESERVOIR PHYSICAL PROPERTIES OF DEEP STRATA IN THE HUANGHUA DEPRESSION

Through the study on the Huanghua depression the authors conclude that the main factors which affect the deep reservoir physical properties in the area include sedimentary environment and facies, diagenesis and the generation and distribution of the abnormal pressure systems in the deep beds. The cementations(especially siliceous cementation and ferrodolomite cementation)are the main cause of the low porosity in the deep strata. The dissolution of acid water is the important factor for creating second porosity and the abnormal pressure zones in deep beds are the important conditions for preserving second porosity.
