利用水平井技术开发低幅度边水油藏

Opening Low Range of Water Boundary Oil Storage To Use Horizontal Well Technologies

古云集沙一下为低幅度边水油藏,油藏高度小,含油条带窄,采用直井开发,油层采收率低。利用水平井开发,可充分发挥水平井有效控制生产压差、防止水体突进的优势。水平井沿油藏顶部钻探,投产后,日产油达80t,实现了高效开发,水平井开发的成功,为类似低幅度边水油藏的开发开劈了新的途径。

Ancient sand gathered about the low rate edge water reservoir, reservoir height is small, narrow strip oil using a vertical well development, it is inefficiency. The development of the use of hori- zontal wells, horizontal wells can give full play to the effective control of the production of pressure to pre- vent water penetration into the advantage, reservoir at the top level of drilling, on stream, oil production up to 80t/d, the realization of a highly efficient development, the success of the development of horizontal wells, while a similar low rate of development of the water reservoir opened a new way.
