辽河凹陷热河台油田火山岩储层评价

热河台油田具有多套含油层系,其中火山岩也是热河台油田的重要储层之一。过去由于研究手段和方法上的限制,对于这套储层在平面上的展布规律缺乏深入认识,给火山岩的勘探开发工作带来了一定的难度,为了搞清这一问题,充分利用了钻井、录井、测井、地震、岩心薄片和分析化验资料,并进行了高分辨率测井约束地震反演,通过综合分析和新技术的应用,对热河台火山岩储层的纵、横向的展布特征有了比较明确的认识。确定了喷发中心的位置,有利的储集相带主要发育在粗面岩中,受构造裂缝控制,分布在火山岩斜坡相部位,可作为火山岩油气藏勘探的主攻方向。

ReHeTai oil field has many oil-bearing strata, among them the volcanics is one of the important reservoir. In the past we didn＇t have thorough understanding on this reservior＇s flat distribution law because of the restrict on the research means and methods. So it has some difficulty for the study of vocanics exploration and development. For making clear this problem, we make full use of the drilling, logging, seismic, core wafer and analysis date and carry on the high resolution logging constrained seismic inversion . And we have more explicit view on the ReHe Tai volcanics reservoir＇s vertical and horizontal distribution law by using the comprehensive analysis and new technique. We also make sure the eruption center position. Profitable reservoir facies tract which mainly exited in trachyte and distributed among the volcanics slope facies because controlled by the structure fracture can be the principal program of vocanics reservoir exploration.
