摘要
水平井开发作为提高单井产量的一种新途径，近年来在华庆油田试验并大规模应用，Y284井区已成为长庆油田20×10^4t级水平井开发示范区之一。通过利用矿场统计和油藏数值模拟方法在水平井轨迹优化、井网完善、储层改造布缝方式以及超前注水政策优化等方面取得了一定的经验认识，为该类油藏的后续水平井开发提供了借鉴作用。
The development with horizontal well （s）, as a new way of improving single well production rate, has been tested in and applied in a large scale to the Qing-hua oilfield in recent years. The well Y284 district in Changqing Oilfield has become one of the 20 ×10^4t level horizontal-well development demonstration areas. By means of numerical simulation of reservoir and field statistics, the horizontal-well trajectory optimization, well pattern, patterns of induced fracture distribution in reservoir and waterflooding-in-advance policy optimization achieved some experience and understanding. It provides some references for the follow-up of this kind of reservoir development with horizontal well（s）.
