摘要
随着油田的不断开发,储层含水逐年上升,层间矛盾日益突出,常规找水工艺如井温找水、封隔器找水等工艺精确度不够,在大斜度井、水平井存在仪器下入困难,测试数据不连续等诸多缺点。采用连续油管底带高温存储式聚能声波及微温差组合测试仪进行测试找水,可准确找到漏点及含水段,判断来水方向,为下一步堵水施工提供可靠的依据,达到控水稳油的目的。
With the continuous development of oilfield,the reservoir water cut increases year by year,the contradiction between the layers is prominent greatly,which results in that the precision of conventional tracing water processes such as temperature,packers to find water is not enough,and many shortcomings are occurred like being difficulties of the instrument down in high angle or horizontal Wells and discontinuity of the test data. Using the combination tester of high temperature storage type shaped acoustic waves at bottom of the coiled tubing with small temperature difference to trace water,can find leak source and section of water cut accurately to determine water direction,which provides the reliable basis for the next step of water plugging operation to achieve the goal of stabilizing oil production by water control.
