雷家地区古近系沙四段湖相白云岩成因
|
摘要
辽河西部凹陷雷家地区古近系沙四段中广泛发育湖相白云岩,是油气勘探的主要目的层段。白云岩主要形成于滨浅湖环境中,垂向上与泥岩、油页岩及生物灰岩共生。通过对雷家地区沙四段白云岩沉积学理论上的成因分析,认为白云岩主要属于成岩埋藏白云岩和准同生白云岩,且古气候条件和海侵作用为湖相白云岩的形成创造了条件。
The lacustrine dolostone develops extensively and is the main purpose strata for the oil and gas exploration in Paleogene Sha 4 Member in Leijia area of western Liaohe sag. The dolostone are formed in shallow lake and are assoiated with mudstone,oil shale and bioclastic limestone vertically. Through the study of dolomite genesis on theory,the two models of dolomization have been set up,i. e. the burial diagenetic dolomization and the penecontemporaneous dolomization. The palaeoclimate and transgression have exerted an important effect on the formation of the lacustrine dolostone.
