齐家地区潜山内幕隔层及其对油气分布的影响
|
摘要
一般认为,太古宇潜山油藏岩性为混合花岗岩,油藏类型为块状油藏。从辽河坳陷齐家地区太古宇潜山的勘探开发实践出发,通过岩心观察和薄片分析鉴定潜山的主要岩性,识别出隔层和储层,综合运用测井、地震资料对隔层在平面与纵向上的分布进行研究。分析认为,齐家地区太古宇潜山隔层为煌斑岩,其在平面上分布稳定,影响着潜山油藏的油气分布,使潜山油藏分隔为多个油气藏。这种潜山隔层的识别与预测方法,为潜山油藏类型的确定提供了依据,为勘探开发工作提出了新的思路。
The Archaeozoic rocks of buried hill is mixed with granite and the reservoir type is massive oil reservoir. Starting from the exploration and development practice in Qijia Region of Liaohe Depression,this paper first identifies the major rocks of buried hill through core observation and slice analysis, and recognized the interlayer and reservoir. And then, it studies the interlayer distribution in the plane and the vertical by comprehensively using the logging, seismic data. The result shows that the Archaeozoic buried hill interlayer in the Qijia Region is lamprophyre. The lamprophyre distributes stably in the plane and influences on the distribution of oil and gas in the buried hill reservoir, which is divided into two relatively independent reservoirs. This method of recognizing and predicting the buried hill interlayer can provide a basis for determining the buried hill reservoir type and proposes a new thinking for the exploration and development.
