吐哈盆地中侏罗统储集层岩石物理相研究──以葡北-胜北-连木沁地区为例

吐哈盆地中侏罗统储集层成因机理十分复杂,为了更精确地预测有效储集层的分布及其内部储集性能的差异,应用了岩石物理相的概念,在吐哈盆地葡北－胜北－连木沁地区开展了储集层质量评价的研究工作。该项研究是建立在储集层沉积相和成岩储集相研究的基础之上,通过二者有机的结合和延展,来研究储集层岩石物理相的时空展布,同时依据储集层物性参数特点和储集层类型配置关系,划分出了六类岩石物理相类型。该分类结果将对油田的勘探开发起到指导作用。

Study on Petrophysical Facies of Middle Jurassic Reservoir in Turpan-Hami Basin-An example from Pubei-Shengbei-Lianmuqin Area

The Middle Jurassic reservoir in Turpan-Hami basin is characterized by complexity in itsgenetic mechanism. By employing the concept of petrophysical factes, the evaluation of reservoir quality inPubei --Shengbei -- Lianmuqin area of the basin is made in order to more accurately predict effective thick-ness distribution and its storage capacity. This study is based on the research of sedimentary factes and diagenetic factes of the reservoir followed by organic superimPOsed and extension between them, and givesthe time-space distributions. And on the basis of the characteristics of reservoir petrophysical parametersand configuration relationship of reservoir types, six kinds of petrophysical factes are classified. It is indicated that the classification will be as guide for petroleum exploration and development in Turban-Hamibasin.
