通过对鄂尔多斯盆地南部麻黄山西地区侏罗系延安组构造、沉积、储层等石油地质特征进行分析，总结出了该地区油气富集成藏规律。根据该区研究成果进行探井部署，在侏罗系延安组油层组取得了重大油气发现，试油获高产工业油流，实现了该区块的油气突破目标。

Through the geological characteristics analysis of structures, sediment and reservoirs in Jurassic Yan’an Formation of
Mahuangshan region in south Ordos Basin, this paper sums up the laws of hydrocarbon accumulation in the region. The important
findings of oil and gas have been obtained in Yan’an oil measures of Jurassic Yan’an Formation according to the research results.
The industrial flowstream of high production has been got through well test, which realizes the goal of oil and gas findings
