辽河西部凹陷齐62井区岩性油气藏储集层特征及识别技术
|
摘要
齐62井区位于辽河西部凹陷西斜坡的齐家—欢喜岭下台阶坡洼过渡带,经过多年勘探,目前已发现了太古宇、中生界、新生界多套含油气层系,但对研究区的储集层特征及识别技术认识不清。应用层序地层学原理,建立了研究区高分辨率层序地层格架,将新生界沙三段划分为3个三级层序,并在各个层序中识别出了低位体系域(LST)、水进体系域(TST)和高位体系域(HST)。同时,以等时地层格架为基础,小时窗范围内采用分频技术、三维测井约束反演技术和地震属性分析技术识别和预测储集层,优选出3个有利岩性圈闭油气藏,部署了齐231井、齐232井、齐233井3口探井,均获良好油气显示。图7参10
The Qi62 well area lies in the transitional slope-depression belt of the Qijia-Huanxiling down-step,in the western slope of west Liaohe Sag.Over several years of exploration,multiple sets of hydrocarbon reservoirs in the Archaeozoic,Mesozoic and Cenozoic have been found,but the characteristics of the reservoirs and identification techniques are unknown.Based on the principle of sequence stratigraphy,high-resolution stratigraphic frames are constructed in this area.The Member 3 of Cenozoic Shahejie Formation is divided into three third-order sequences,each with LST,TST,HST identified.Simultaneously,on the basis of an isochronous stratigraphic framework,the frequencydivision technique in small time interval,the three-dimensional log constraint inversion,the seismic attribute identification,and the forecasting reservoir technique are used to choose three good lithologic trap reservoirs and arrange three wells Qi 231,Qi 232,Qi 233.All these wells show oil and gas.
