2、受埋藏深度、流體l生質(zhì)、儲(chǔ)層特征、地層溫度和壓力等多因素的影響,同時(shí)也受開發(fā)工藝水平的影響。因此采用多種方法綜合確定了物性下限。通過求取研究區(qū)不同深度的物性下限,結(jié)合儲(chǔ)層性質(zhì)、埋深、溫度和壓力等探討影響物性下限的主控因素。儲(chǔ)層性質(zhì)、埋藏深度和地層溫度是深層致密砂巖有效儲(chǔ)層發(fā)育程度的主控因素。次生孔隙會(huì)增大有效儲(chǔ)層孑L隙度下限,物性下限隨著埋深的增加而減小,隨地層溫度的增加有效儲(chǔ)層物性下限降低。地層壓力對(duì):有效儲(chǔ)層發(fā)育影響較大,深部超壓使有效儲(chǔ)層物性下限降低。流體性質(zhì)對(duì)儲(chǔ)層有效性影響相對(duì)較小。關(guān)鍵詞:西部凹陷;深層
