摘要: 鄂尔多斯盆地东缘雷家碛地区盒8段广泛发育辫状河砂体,为典型的致密砂岩气储层。为解决因地震资料品质约束造成的气层预测困难问题,开展了实验室岩心分析测试等方面的研究。结果表明:①雷家碛地区盒8段以岩屑砂岩和长石岩屑砂岩为主,储集空间类型包括残余粒间孔、粒间溶孔、粒内溶孔等,面孔率低,孔喉分选差,孔隙结构复杂,为典型致密砂岩储层;②压实作用、压溶作用和胶结作用均为破坏性成岩作用,而溶蚀作用和构造破裂作用均有效改善了岩石的储集性;③各成岩作用对岩石的改造可引起岩石物理参数变化,依据在三维地震数据体中提取的"甜点"属性与叠前反演得到的泊松比属性,在平面上划分出建设性成岩作用所形成的有利区,可有效预测天然气富集区。根据上述方法部署的LX-41井,其钻探结果与预测结论较为一致。研究成果对类似区域的"甜点"预测具有一定的借鉴意义。
