摘　　要：查干诺尔凹陷是海拉尔盆地西南部的一个二级负向构造单元。查干诺尔凹陷的主要烃源岩是南屯组和大磨拐河组的泥岩。凹陷内广泛分布铜钵庙组、南屯组和大磨拐河组3套储集层。伊敏组泥岩是区域性盖层,大磨拐河组和南屯组泥岩是局部盖层。断块、断鼻和地层超覆等油藏类型较为发育。东部断阶带的中南段、西部斜坡与中央凹陷过渡带的中南段是有利勘探区带。Chagannuoer Depression is a negative secondary building unit, located in the southwest of Halar Basin. The main source rock of Chagannuoer Depression is the mudstone of Nantun Formation and Damoguaihe Formation. Three reservoirs of Tongbomiao Formation, Nantun Formation and Damoguaihe Formation are widely distributed in this Depression. Mudstone of Yimin Formation is regional cap rock, and that of Damoguaihe Formation and Nantun Formation is local cap rock. Fault block, fault nose and stratigraphie overlap are well developed in this area. Favorable exploration area includes the central-south interval in the eastern fault terrace belt, the western slope and the centralsouth interval in intermediate zone of median depression.
