针对国内目前井下取样器不抗硫化氢、所取样品不保压等问题,研制出新型高抗硫保压井下取样器,该种取样器选材选用钛合金和全氟醚胶圈,解决了抗硫化氢腐蚀问题;采用氮气室背压保压技术,确保在取样、转样、运输过程中的样品压力始终大于取样点压力,实现了全程保压,保证所取样品相态不发生变化.在普光气田P202-1井成功取得2支可代表地层真实流体特性的井下PVT气体样品.

It has two main characteristics:the selection of titanium alloy and desflurane?apron?solves?the?problem?of?resistance?to?hydrogen?sulfide?corrosion;?nitrogen?chamber?holding?pressure?technique?is?taken?to?ensure the sample pressure is always greater than the pressure of the sampling point, during sampling, transferring, and transporting pro-cesses, in other word, to ensure full holding pressure and no phase change. Two downhole PVT gas samples were successfully obtained from?Well?P202-1?in?Puguang?gas?field,?which?can?represent?the?true?formation?fluid?properties.
