大情字井油田葡萄花油层沉积微相
|
摘要
本文根据大情字井姚家组钻井取心、测井、地震等资料,以沉积学、测井学、构造地质学、石油地质学等理论为指导,对该组进行小层划分,开展姚家组沉积微相研究,总结该区各层段微相的平面展布特征,对有利储集砂体进行评价。通过对目前已发现的乾157等区块研究资料的解剖与分析,确定藏葡萄花油层的可能存在的油藏类型,得出油气聚集规律,预测有利区带。
在系统观察与描述岩心的基础上,结合下层段青山口组青三段(三角洲前缘)及周围地区的沉积环境确定大情字井姚一段确定岩心地质相为流河沉积。应用等厚法,等高程法将葡萄花油层分为3个砂组,6个小层,建立葡萄花油层的地层格架。
通过葡萄花油层岩电对比,重点进行岩心地质相、测井相分析及相模式建立,确定单井沉积微相,分析沉积微相平面展布特征。微相类型为边滩沉积,底部滞留沉积,天然堤沉积,河漫滩沉积,决口扇沉积,及泥质淤积。通过开发密井区相带和重矿物含量可明确物源方向为西南方相,物源为西南保康水系。
对不同沉积微相砂体岩性、物性及渗流特性的对应分析,明确沉积微相对储层储集性能的影响,预测有利储集相带及有利的储集体。
通过对目前已发现的乾157等区块研究资料的解剖与分析,确定该油藏葡萄花油层的成藏模式类型,寻找不同沉积微相与油气分布的关系,确定有利油气富集的相带及有利油气分布的控制因素,结合葡萄花层段试油、试采资料确定有利油气富集的区,预测乾157、乾148、黑43、黑53、黑124、黑115等6个区块为可能油气富集区块。
In this paper, based on the data of core-drilling wells, logging, seism of Yaojia Formation in Daqingzi, and sedimentology, logging, structural geology, petroleum geology, as guides, the group is divided into small layers, the sedimentary microfacies of Yaojia formation is carried out, the platform distribution characteristics of sedimentary microfacies of each formation is summarized, and the favorable reservoir sand body is evaluated.
Through the research and analysis on Qian157 block and the others founded by now, the potential oil and gas reservoir types of Putaohua formation are determined, the oil and gas accumulation rules are made out, and the favorable block is predicted.
On the base of core data, synthesizing logging data as consult and combining with the lower substratum qn3 (delta front) and the sedimentary environment of surrounding area, the core geologic facies of y1 segment in Daqingzi is fluvial facies. By using the method of isopach and isobath, Putaohua reservoir is divided into three sand groups and six small layers and the stratigraphic framework is set up.
Through the contrast of electric proper and rocks, the establishment of core geological facies, logging facies analysis and facies model, the determination of sedimentary microfacies of wells and the analysis on platform distribution characteristics of sedimentary microfacies are emphasized. The microfacies types are sediment bar, bottom remains, natural levee, floodplain, crevasse splay and argillaceous sediment. Through exploiting the phase belts in dense wells block and heavy minerals content, the source direction determined is southwest and the sedimentary source is the Baokang river system in southwest.
The analysis on sand body lithology, physical properties and flow characteristics of different sedimentary microfacies can determine the effect that sedimentary microfacies on relative reservoir properties and predict favorable reservoir facies zone and reservoir.
Through the research and analysis on Qian157 block and the others founded by now, the accumulation models types of Putaohua and the connection between different microfacies and distribution of the oil and gas are determined, as well as the control factors of the favorable oil and gas accumulation block. With the testing and production test data of Putaohua, the favorable oil and gas accumulation zone are determined, and six potential accumulation blocks, Qian157, Qian148, Hei43, Hei53, Hei124, Hei115, are predicted.
