Based on the origins, the pressure seals include diagenetic seals, structural seals, capillary seals and filling seals.

成岩作用、构造作用、毛细管力作用、差异渗透作用和充填作用等是压力封闭层形成的主要机制。

Based on the analysis of core and thin slice,it is concluded that the forming of Ma 51 dolomite reservoir is dominated by hypergene karstification,burial dissolution and mineral filling.

岩心与薄片分析表明,该研究区的表生岩溶作用、埋藏溶解作用和矿物充填作用对马五1亚段白云岩储集层形成的影响较大。
