以塔河油田AT9井区三叠系阿四段河道砂油藏为例，通过对隔层的精细描述认为，该油藏中主要发育2套平行于层面的隔层，隔层延伸长度大于水平段长度，若采用常规水平井难以有效控制储量。针对该类储层特点，选取台阶状水平井开发对策，最大限度提高了隔层上下油层储量动用程度，取得较好地应用效果。

With the channel sand reservoir of the 4th member of Triassic akekule formation in Tahe oil field as an exam-ple,through fine description between interlayers,there are 2 interlayers,which are parallelled to the layers,and the exten-sion length of interlayers is greater than the length of horizontal section.Using the traditional horizontal well is difficult to effectively control reserves.Stepped horizontal well development strategy,which can extremely increase reservoirs used degree,were selected in view of this kind of reservoir,and good application results were obtained.
