塔河油田南部奥陶系一间房组层序地层、储层预测及质量评价研究
|
摘要
依据层序地层学理论,通过露头、钻井、测井及地震资料的综合研究,将一间房组划分为一个三级层序;高水位体系域晚期至少划分出5个高频层序,并刻划了三级层序及高频层序单元滩相展布。在此基础上进行了储层预测,并有如下结论:纵向上储层发育受三级层序及高频层序控制;平面上储层主要发育于台内坡折带以北的滩体中心。最后通过储层孔渗变化与控制因素的匹配分析,探索建立储层质量控制模式。即通过储层质量与高频层序、滩体部位及构造部位关系的研究,得出第Ⅴ高频层序储层质量优于第Ⅲ高频层序;滩体中心储层质量优于滩体边缘;塔河油田西南部、南部储层质量优于塔河油田东部。
According to sequence stratigraphy,on the basis of integrated study on outcrop,well drilling,well logging and seismic data,one third-order sequence has been recognized in the Yijianfang Formation.In the upper of the high system tract,at least 5 high frequency sequences have been recognized.And beach facies distribution is depicted both in third-order sequence and in high frequency sequence.Then based on the foregoing research,the reservoir in this area has been predicted and conclusions have been made as follows:Vertically,the development of reservoir is controlled by sequence and high-frequency.Flatly,the reservoir develops on the center of the beach which lies in the north of break of slope in the platform.Then by researching the relationship between reservoir qualities and controlling factor,controlling mode of reservoir quality has been set up.At last,by researching the relations between reservoir quality and high-frequency,beach position and tectonic,it can be seen that the fifth high-frequency's reservoir quality is superior to the third,beach center quality is superior to the edge,southwest and south of Tahe oilfield's quality is superior to the east.
