| 摘 要： | 塔里木盆地寒武系—奥陶系白云岩具有时代老、埋藏深、成岩作用复杂的特点。白云岩储层储集空间主要为孔隙和裂缝两大类,其中孔隙类型可进一步划分为晶间孔、晶间溶孔、晶内溶孔、铸模孔、溶蚀孔洞等;裂缝类型可进一步划分为缝合线、风化裂缝和构造裂缝。根据储集空间类型特征,白云岩储层可以划分为孔隙型、孔洞型、缝洞型和裂缝型4种。孔隙型储层和缝洞型储层物性较好。根据成因白云岩储层可以划分为准同生白云岩储层、埋藏型白云岩储层、构造-热液型白云岩储层和风化壳岩溶型白云岩储层,其中后两者及其复合类型常形成优质储层。 |

| Abstract: | The Cambrian-Ordovician dolomite in Tarim basin is characterized by old age,deep burial and complex diagenesis.The space of the dolomite reservoir is mainly composed of pores and cracks.The pores can be further divided into such types as intercrystal pores,intercrystal dissolved pores,intracrystal pores,moldic pores and dissolved holes,while the cracks can be further divided into satures,weathering fractures and structural fractures.According to the characteristics of reservoir space,dolomite reservoirs can... |
