摘　　要：本文认为沉积相对储层物性的分布起了特别重要的控制作用,研究表明储层物性分布具有方向性,沉积时高能带与低能带的差异导致这种方向性分布的根本原因。研究区长4+52孔隙度、渗透率方向性沿分流河道高能带呈高值条带状分布。Sedimentary played very important control function in reservoir physical property distribution, studies have suggested , reservoir physical property distribution have directionality . The basic reason for this kind of directionality distribution is the difference between high energy and low energy in semidentment , Chang 4＋5 2 porosity , penetrance directionality distribute a high mark banding along distributary channel high energy area in this study area.
