惠民凹陷东部火成岩披覆油藏特征及构造描述
|
摘要
火成岩披覆油藏是一种特殊的油藏类型。惠民凹陷东部地区处于济阳坳陷中部的临邑-滨县火成岩发育带上,在馆陶组-沙河街组地层中发育了多种成因类型的火成岩体,其中与蘑菇状、丘状地震相火成岩相伴生的披覆油藏广泛发育。文章阐述了火成岩披覆油藏的成因、特征,研究了其成藏规律及分布特点,并应用一系列地球物理方法对其进行了描述,实施后取得了良好的钻探效果。
Igneous drape reservoir is a special type of reservoir. Eastern area of Huimin sag is located on the Linyi-Binxian igneous zone in the mid-part of Jiyang depression. Igneous rocks of various genesis had developed in Guantao-Shahejie formation, among which, extensively developed was drape reservoirs associated with igneous rocks of mushroom and mound seismic facies. This paper discusses the genesis and characteristics of igneous drape reservoirs, and studies reservoir forming and distribution features. A series of geophysical methods are used in description of such reservoirs, and good exploration result has been achieved.
