海拉尔盆地苏德尔特油田布达特潜山油藏储集层特征

摘要
布达特潜山储层是海拉尔盆地苏德尓特油田的主力油层。针对布达特储层岩性复杂,物性较差,储层类型复杂等特点。根据岩心描述资料、岩石薄片资料和裂缝测井资料对布达特潜山储层岩性、物性、电性特征进行了研究。确定储层主要类型有孔隙型、裂缝、孔洞及溶孔型属于双孔隙介质储层。并结合地震属性方位角各向异性预测将布达特储层纵向分为风化破碎带,裂缝、溶孔、溶洞发育带和致密带。平面上受构造位置和断裂位置共同控制,断裂带附近和高部位更容易形成好的裂缝储层。
Budate buried hill reservoir is the main oil layer of Sudeerte oilfield in Hailar Basin.In view of complex lithology,poor physical property and complicated reservoir type etc.of Budate reservoir,according to core description data,thin section data and fracture logging data,the reservoir lithology,physical properties and electrical characteristics of Budate buried hill are studied.Determine the main reservoir types include porous reservoir,cracks,holes and dissolved pore reservoir,which is the double-porosity medium reservoir.Combined with azimuthal anisotropy of seismic attributes,predict Budate reservoir in vertical can be divided into weathering broken belt,cracks,dissolved pore and caves development belt,and dense zone.In plane,because of the control action of structure and fracture position,near fracture belt and high position are easier to form a good fractured reservoir.
