摘要
针对目前胜利油区海上埕岛油田产液量低、采油速度低和预测的平台安全使用期末采出程度低等问题,在建立地质及动态模型的基础上,应用油藏工程、数值模拟和经济分析等方法,提出了该油田馆陶组油藏开发调整技术政策。研究结果表明,局部细分2套层系可减缓层间干扰;在四点法面积井网的基础上,因地制宜加密井网可提高平面储量动用程度;当地层压力恢复到11.5MPa时,适时提液可减缓油田综合递减,提高采油速度;预测平台安全使用期末的采出程度比按目前产液量水平生产可提高2.3%～7.6%。
Because of low liquid producing capacity, low rate of oil production , and low recovery percent of reserves in the safety life of platform in offshore Chengdao Oilfield of Shengli petroliferous province, development technique policy of the oilfield is adjusted using the methods of reservoir engineering,numerical simulation,economic analysis,etc. on the basis of geologic and dynamic models. The results show that local two series of strata divided may slow down the interlayer interference. On the basis of four - spot areal well pattern, infill well pattern with local conditions will improve the degree of producing reserves on the plane. When the formation pressure is to be restored to 11.5 MPa, increasing liquid production in good time will slow down the composite decline and increase the oil production rate of the oilfield. The recovery percent of reserves will increase 2.3% to 7.6% in the safety life of platform than that on current liquid production level.
