下二门油田东部地区核三段I、II油组岩石学特征
|
Abstract:
在充分吸收前人研究成果的基础上,综合运用地质、测井、录井、分析化验及生产动态等资料,以地质学理论和精细油藏描述技术为指导,基于“重视基础”的原则,采用宏观与微观相结合、定性与定量相结合的综合研究方法,开展下二门核三段岩石学特征研究,从而得出下二门油田核三段岩石学特征是:结构成熟度低,成份成熟度低,即分选差,石英、长石含量低,岩屑含量高且不稳定组分占多数。通过沉积岩石学和相标志加重矿物的分布特征分析这一创新点,得出了I、II油组时期,下二门油田存在来自西北方向的侯庄地区和东部山区两个方向的物源,其中以来自西北方向侯庄地区的物源为主,东部山区物源为辅。为研究区的沉积体系研究提供了基础,同时为下二门东油田的油气勘探提供了有效依据。
This article mainly introduces the petrological characteristics of the third member of Hetaoyuan in the eastern part of Xiaermen Oilfield. On the basis of fully absorbing predecessor research re-sults, comprehensive use of geology, logging, logging, analysis and testing, production performance and other data, guided by geological theory and fine reservoir description technical ideas, based on emphasis on the foundation, close to production. Based on the principle of “Integral Anatomy”, the comprehensive research methods of combining static description and dynamic simulation, macro and micro, qualitative and quantitative are adopted to carry out the study of petrological characteristics of the third member of the Lower Ermen core, and the lower Ermen is obtained. The general petrological characteristics of the third member of the Hepu Member of the oilfield are: low structural maturity, low component maturity, that is, poor sorting, low quartz and feldspar content, high debris content and most unstable components. Through the analysis of sedimentary petrology and the distribution characteristics of facies marker weighting minerals, it is concluded that in the period of oil formation I and II, there are two sources from the Northwest Houzhuang area and the eastern mountainous area in Xiaermen oilfield, in which the source from the Northwest Houzhuang area is the main source and the Eastern mountainous area is the auxiliary source. It also provides a basis for the study of the sedimentary system in the study area, and at the same time provides an effective basis for the oil and gas exploration in the Xiaermendong Oilfield.
