| 摘 要： | 现有排水采气技术虽然能够有效地将井筒中的地层水采至地面,但也给地面的气液分离带来了困难,不仅需要建设大量的地面气液分离设备,而且对所分离出的地层水的处理也需要投入大量的资金,影响着气田的高效开发。为此,在对分离器的分离效率进行探讨的基础上,对井下气液分离及同井回注技术在胜利油田气井的应用效果、技术优势和存在的问题进行了讨论。现场生产表明:井下气液分离及同井回注技术是在井下经过螺旋气液分离器将出水气井的产出液进行分离,然后将分离出的水在井下回注到另一水层或枯竭气层中,该技术可以减少大量的地面设施、减少环境污染,具有较好的经济效益和社会效益,也为胜利油田现已探明的34个浅层气田的高效开采提供了有效的技术支撑。

| Abstract: | The existing gas-producing and drainage technology can take water out of well hole efficiently.However,it demands considerable ground equipments and lots of money to run so that this will seriously affect the profit in gas reservoir exploitation.Based on a discussion on the efficiency of the separator,the application effects of the downhole volute separator in gas wells of the Shengli Oilfield is studied in this paper.The production results demonstrate that the technology of downhole separation and reinject... |
