中文摘要	截至2017年,鄂尔多斯盆地苏里格地区有利勘探面积为5.510~4km~2,天然气总资源量近6.010~(12) m~3,已探明(含基本探明)储量为4.7710~(12) m~3,已建成产能为23010~8 m~3/a的天然气生产规模,是中国陆上发现的储量最大的天然气田。多年研究表明:①苏里格气田产层主要为上古生界二叠系石盒子组8段和山西组1段,为典型的致密砂岩气藏;②石炭系本溪组、二叠系太原组和山西组广泛发育的煤系地层为气藏提供了充足的气源;③发育敞流型湖盆三角洲沉积模式,平缓底形、多源供砂、强水动力、多期叠加控制着大面积储集砂体的分布;④储层为河流三角洲相砂岩,物性较差、非均质性强,平均孔隙度为4%~12%,平均渗透率为0.01~1 mD;⑤气藏具有广覆式生烃、弥漫式充注、近距离运聚、大面积成藏等特征;⑥气藏压力系数为0.62~0.90,属低压气藏,单井产量低;⑦沙漠区全数字地震技术、黄土塬非纵地震技术、测井精细评价技术、致密砂岩储层改造技术、水平井开发技术是苏里格气田勘探开发的关键技术。
英文摘要	By the end of 2017,the Sulige area in Ordos Basin has the favorable exploration area of 5.510~4 km~2,the total reserve of natural gas of nearly 6.010~(12) m~3 and the proven reserve(including basic proven reserve)of 4.7710~(12) m~3,where the annual production of natural gas reaches 23010~8 m~3,and the Sulige gas field is the largest onshore natural gas field in China.The pay zone of the Sulige gas field mainly is Member 8 of Shihezi Formation and Member 1 of Shanxi Formation of Permian which belong to the typical tight sandstone gas reservoir.The coal measure strata in Carboniferous Benxi Formation,Permian Taiyuan Formation and Shanxi Formation provide abundant gas sources for the Sulige gas reservoirs.An open-flow sedimentary model of lacustrine delta is developed, the gentle bottom,sand supply from multi-source,strong hydrodynamic force and multi-period superposition control the distribution of large-area reservoir sand body.Lithology of the reservoir is the sandstone of the fluvial-delta facies,the physical property is poor and the heterogeneity is strong,the average porosity ranges from4%to 12% and the average permeability varies from 0.01 to 1 mD.The gas reservoir is characterized by wide hydrocarbon generation,pervasive hydrocarbon charging,short-range migration and massive accumulation.The pressure coefficient of the gas reservoir ranges from0.62 to 0.90,indicating the low-pressure gas reservoir,and the single-well production is low.Full digital seismic technique in the desert area,non-longitudinal seismic technique in the loess plateau,accurate logging evaluation technique,tight sand reservoir stimulation technology and horizontal well development technology are key technologies for exploration and development of Sulige gas field.
