摘　　要：永安镇油田永 12断块属边底水活跃的层状断块“屋脊”油藏 ,目前已进入高含水、高可采储量采出程度、高剩余可采储量采油速度开发阶段。其数值模拟结果和新井及侧钻井生产动态均表明 ,油藏构造各部位仍有剩余油分布。为进一步提高采收率 ,开展了水平井整体挖潜方案优化研究 ,借助数值模拟技术对水平井距油层顶距离、井段长度、液量保持水平、轨迹等进行了优化设计 。Yong 12 block of Yonganzhen oilfield is a layered fault block ridge reservoir which has active edge water and bottom water, at present it has entered development stage of high water-cut, high production degree of recoverable reserves, high oil recovery rate of remaining recoverable reserves. Numerical simulation and production performance of new wells and side-tracked wells indicate that certain remaining oil still distributes at all positions in reservoir structure. In order to improve recovery efficiency further, optimizing overall plan of horizontal wells for tapping the potential is studied. With the aid of numerical simulation technology, we optimized the design of distance from horizontal well to reservoir top, horizontal well bore length, liquid maintaining level and track, then defined the optimum program.
