酸性气田长井段射孔配套技术

Supporting Perforation Technique With Long Section in Sour Gas Field

传统电缆射孔工艺满足不了高含硫化氢和二氧化碳、气层埋藏较深、气层厚度较大的高酸性气田现场井控以及安全生产的需求;油管传输射孔由于射孔层段较长,一次性射孔的难度较大。针对上述难题,研究出一套满足高含硫气田投产安全生产的长井段射孔配套技术及辅助配套技术,经在气田30口井的现场应用,成功率100%。

Traditional wireline perforation technology can't meet the need of well control and operation security in sour gas field with high content of hydrogen sulfide and carbon dioxide gas,deep buried layer,high thickness.Tubing conveyed perforation is difficult to make true at once time because of long perforated section.In response to these problems,a set of supporting perforation tech and its auxiliary technologies to meet the production safety of long perforated section in high sulfur gas field are developed,that has been applied in more than30 wells and the success rate is 100%.
