【摘要】 介绍某油田变形观测的监测和数据处理方法,分析油田变形的原因,并根据多期变形观测数据,对频繁发生井管破损的采油区逐渐地进行采油与注水比的调整,使地层压力的过大变化得到有效控制,从而找到油田地面变形及井管破损的原因,为防治井管破损、保证油田稳产提供可靠依据。更多还原

【Abstract】 The reason of ground deformation of oil field is found by establishing 3D deformation nonitoring network of oil field, and making the monitoring at regular intervals, and data processing and deformation analysis for the network. According to repeatedly deformational observing data, an grandually proper adjusting ratio between oil extraction and water flooding in the place well pipe damage occurred frequently, and effectively control greater changes in the pressure of the earth surface, it proivdes reliable basis for preventing well pipe damage and guarantee steady production in the oil field.更多还原
