摘要

红杉油田位于西三角洲深水特许经营区内,是埃及尼罗河三角洲深水斜坡河道的代表。主要含烃地层为晚上新世埃尔瓦斯塔尼组。El Wastani组红杉水道被认为是红杉油田的主要储层。利用计算机软件程序(如交互式岩石物理(I.P.))完成了5口井的测井数据分析。利用软件进行岩石物性评价,对El Wastani组红杉通道进行岩石物性分析,确定有效孔隙度、页岩体积和储层流体饱和度,是本研究的主要目的,目的是更好地确定红杉油田储层质量。研究发现,El Wastani组红杉通道具有较高的储层容量,可容纳大量的油气流体。结果表明,有效孔隙度在19% ~ 29%之间,页岩含量在10% ~ 28%之间,含水饱和度在15% ~ 40%之间。研究表明,相效应是控制储层物性分布的主要因素。

Sequoia reservoir evaluation through conventional petrophysical analysis in Eastern Mediterranean, Nile Delta, Egypt
ABSTRACT The Sequoia Field, in West Delta Deep Marine concession, represents deep marine slope channels in Nile Delta of Egypt. The main hydrocarbon bearing formation is the Late Pliocene El Wastani Formation. Sequoia Channel of the El Wastani Formation are considered as the main reservoirs of Sequoia Field. Well log data analysis, of five wells were accomplished using computer software programs (e.g. Interactive petrophysics (I.P.) Software was used in petrophysical evaluation for Petrophysical analysis, in terms of determining the effective porosity, shale volume, and reservoir fluid saturation of Sequoia Channel of El Wastani Formation, is the primary aim of this study in order to achieve better determination of the reservoir quality in Sequoia Field. We found that Sequoia Channel of El Wastani Formation is having high storage capacity properties permit them of bearing a good amount of hydrocarbon fluids in the Sequoia Field. It was found that effective porosity ranges between 19% and 29%, shale content ranges between 10% and 28%, the water saturation ranges between 15% and 40%. It is clear that the facies effect is the main factor that is controlling the distribution of the petrophysical properties.
