白云岩是碳酸盐岩油气藏的重要储集层类型,确定优质白云岩储集层发育的主控因素及相应的地质背景对于指导白云岩油气勘探具有重要的现实意义。实践证明,原岩类型和白云石化作用机制是控制白云岩基质孔隙发育程度的主要因素;后期各类岩溶作用的改造对于优质白云岩储集层的形成尤为关键。白云岩成岩作用研究表明,在深埋条件下,白云岩既可发育大量晶间孔,又易形成溶蚀孔洞,孔洞形成后保存情况良好,有效储集空间的发育不明显受白云岩埋藏深度的制约,深埋的白云岩仍可具备优越的储集物性而成为优质储集层。由高能相带沉积物转变形成的埋藏成因白云岩、热液成因白云岩以及构造活动和水-岩作用活跃地区...

Dolomite is an important type of carbonate reservoirs. The understanding on the master control factors of high-quality dolomite reservoirs and the corresponding geological settings is of great significance to dolomite hydrocarbon exploration. Theories and case studies prove that the initial rock and the mechanism of dolomitization are key influential factors on the matrix physical properties of the dolomite. Karstification is the most critical process in the development of high-quality dolomite reservoir. Recent diagenesis study indicates that a great amount of intercrystal and corrosion pores...
