| 中文摘要: |
| 位于三塘湖盆地中部的马郎凹陷是油气重点区带之一,面积1500km2,区内二叠系芦草沟组为主要勘探目的层。对芦草沟组储层特征综合研究表明,区内储层岩石类型复杂,以碳酸盐岩、凝灰岩为主,次为火山岩;储层空间类型多样,以基质溶孔(包括晶间溶孔、晶内溶孔及缝内溶孔)和裂缝为主,以小孔细喉和小孔微细喉为主,具低孔低渗的特征。进而总结影响储层性质的主要因素为埋藏溶蚀作用、白云岩化作用、储层岩石学方面和构造作用。 |

| Malang Depresss covering an area of 1500 km2 is located at the middle of the Santanghu Basin.It is the key target for oil gas reservoir of the Permian Lucaogou formation.The reservoir is characterized by many rock types in oreder of carbonate rock and tuff,then volcanics;interspace of the reservoir by a variety of types,such as matrix dissolution pore(including intercrystal,intracrystal and slit dissolution pore) and slit,minipore thin-throat and minipore mirco-throat,as well as low porosity and permeability.Then the paper sums up the dominant factors affecting the reservoir characteristics.Among them,burial erosion diagenesis,dolomitization,reservoir lithology and tectonism are the most important |
