| 摘 要： | 涠洲12-1油田位于南海西部海域,富含SO42-的注入水(海水)与含有Ba2+、Sr2+的地层水不配伍,导致该油田中块油井结垢现象严重。所结垢为硫酸钡锶垢,硫酸钡含量约占70%,硫酸锶含量约占30%。分析了成垢机理,并对可能的7种防垢方案进行了对比分析,认为注入井调剖与油井注防垢剂组合方案是涠洲12-1油田中块油井防垢的最佳方案。 |
| 关 键 词： | 涠洲12-1油田 硫酸钡锶垢 成垢机理 组合防垢 |

| Abstract: | Weizhou 12-1 oilfield is located in the western of the South China Sea.The serious scaling has occurred in the oil wells in the middle block of the oilfield,due to the incompatibility between injected sea water with rich SO~(2-)_4 and formation water with rich Ba~(2+),and Sr~(2+).The scale is the barium strontium sulfate scale,containing 70% barium sulfate and 30% strontium sulfate.Through analyzing the mechanism of scale formation and(evaluating) 7 probable anti-scaling methods,it is deemed that the combined method of profile controlling in injectors plus anti-scaling agent in producers is the best anti-scaling plan for the oil wells in middle block of Weizhou 12-1 oilfield. |
| Keywords: | Weizhou 12-1 oilfield barium strontium sulfate scale mechanism of scale formation combined anti-scaling |
