摘要:

鄂尔多斯盆地苏里格气田储层岩性致密,成为制约天然气勘探开发的主要因素,因此,开展储层孔隙结构特征研究对于该区天然气生产具有重要意义。通过薄片鉴定、扫描电镜、铸体薄片、压汞等分析测试方法对苏里格气田东二区二叠系山西组一段和石盒子组八段储层的微观孔隙结构特征进行了深入分析。结果表明:苏里格气田东二区山1段、盒8段储层为低孔、低渗储层,且非均质性很强;储层孔隙类型主要为岩屑溶孔和晶间孔;储层孔喉半径普遍较小,孔喉分选较差,孔隙喉道分布不均匀,孔喉连通性差。据储层物性和孔隙结构参数将研究区储层分为4种类型,但研究区以Ⅲ类储层和Ⅱ类储层为主。研究认为沉积作用和成岩作用是鄂尔多斯盆地苏里格气田东二区砂岩低孔\,低渗的主要控制因素。

Abstract:

Compact sandstone reservoirs of Sulige gas field in Ordos basin is becoming the main limitative factor for exploration and exploitation of natural gas. It is significant for output of natural gas in this area to understand the characteristics of pore structure of reservoirs. The micro-pore structure of reservoirs in the first member of Shanxi Formation (Shan1) and eighth member of Shihexizi Formation (He8) in Permian are conducted by means of slice identification,observation of SEM,casting slice and mercury injection in the east Ⅱ block of Sulige gas field. Results show that: ① Shan1 and He8 reservoir is characterized as low-porosity,low-permeability and strong-heterogeneity;② pore types of reservoirs are solution pores of debris and intracrystalline pore;③ small pore-throat radius,poor sorting,poor heterogeneity and poor connectivity. According to physical properties of reservoirs and parameters of pore structure,reservoirs can be divided into four types,and dominated type Ⅲ andⅡ. So,we consider that sedimentation and diagenesis are main controlling factors for low porosity and low permeability of sandstone reservoirs in the east Ⅱ block of Sulige gas field,Ordos basin.

Key words: Ordos basin, Sulige Gas Field, Reservoir, Pore structure, Heterogeneity
