辽河滩海海南—月东缓坡带地层岩性油气藏预测
摘要
岩性地层油气藏是当前国内油气勘探最现实、最有潜力、最具普遍性的领域。辽河滩海海南-月东缓坡带地层岩性油气藏发育,勘探程度低,是辽河油田目前重要的勘探接替领域。因此针对该区开展地层岩性油气藏勘探技术和成藏规律研究,对尽快取得滩海地区的勘探突破具有重要的现实意义。
本文针对缓坡带无井的现状,充分利用构造主体的钻井资料,结合地震反射特征建立起了缓坡带的层序地层格架。在层序框架下通过沉积相、地震相分析技术,对研究区的构造、沉积演化特征进行了系统研究。在层序、构造、沉积研究的基础上,结合波阻抗反演和属性分析等手段预测储层的发育和分布,形成了缓坡带少井区地层岩性油气藏识别和评价方法,总结了区内的成藏条件、成藏规律,建立了缓坡带地层岩性油气成藏模式,预测了岩性地层油气藏的有利发育层位和地区。
通过本论文研究,识别出地层岩性圈闭9个,叠合面积31.4km2,预测圈闭资源量3774万吨,为滩海地区的勘探突破提供了有力支撑。
The stratigraphic-lithologic reservoirs has become the most realistic, potential and widespread fields of hydrocarbon exploration in China. The stratigraphic-lithologic reservoirs develop with a low exploration extent in Hainan-Yuedong gently slope belt of the beach area of Liaohe basin, which is the most important backup fields of hydrocarbon exploration in Liaohe oil field. Therefore, the study on the exploration techniques and accumulation rule of the stratigraphic-lithologic reservoirs is very important to early make progress in petroleum exploration practice of the beach area.
In view of the lack of the well in the gently slope belt, the well data of the main structure are all considered in the process of research. With the seismic response characters, the isochronous stratigraphic framework is built. Through the analysis of the sedimentary facies and seismic facies, this paper studied the structure and deposition evolution characteristics in an isochronous stratigraphic framework. Based on comprehensive study of the sequence, structure and deposition, by using impedance inversion and the seismic attribute identification, the reservoir and its distribution is predicted and the identification and evaluation of the stratigraphic-lithologic reservoirs in the gently slope belt whit a few exploration wells are formed. The reservoir-formning condition and accumulation rule are summarized. The model of hydroarbonate accumulation of the stratigraphic-lithologic reservoirs in the gently slope belt is built. The favorable stratum and area of the stratigraphic-lithologic reservoirs is pointed out.
On the generalization of this paper,9 stratigraphic-lithologic traps and oil-bearing area of 31.4km2 are discovered.3774 million tons of oil geologic reserves is predicted and Haiyue lwell is arranged。It gives a powerful support to enhance the exploration effective in the beach area.
