Development of an Outer Casing Anti-Gas Channeling Device

  • 摘要: 为了预防页岩气井在大型压裂时套管变形对水泥环造成破坏,阻断气窜通道,防止井口环空带压,在分析页岩气井产生气窜通道原因的基础上,研制了一种套管外防气窜装置。通过数值模拟试验、承压变形试验及承压密封性试验,分析了套管及套管外防气窜装置的承压变形规律,验证了套管外防气窜装置的承压密封性能。套管外防气窜装置在70 MP内压条件下,其外部径向变形仅有0.007 mm,不会形成气窜通道,且其在压缩胀封情况下可承受35 MPa的压差,防气窜性能较强。套管外防气窜装置在焦页88-2HF井和焦页93-2HF井产层固井中进行了现场试验,压裂后均未出现井口环空带压现象。性能试验和现场试验表明,套管外防气窜装置能减轻套管变形对水泥环的破坏,防止水泥环因大型压裂出现微间隙,达到防气窜的目的,可为页岩气井防气窜提供一种新的技术手段。
    Abstract: In order to prevent damage of cement ring caused by casing deformation during large scale fracturing,block gas channeling path and prevent wellhead pressure,an outer casing anti-gas channeling device was developed based on the analysis of gas channeling causes in shale gas well.Through a numerical simulation test,a pressure deformation test and a pressure seal test,the pressure deformation law of the casing and the outer casing anti-gas channeling device was analyzed.Using that information,the pressure seal performance of the outer casing anti-gas channeling device was verified.Under a casing pressure of 70 MPa,the outer radical deformation of the device was only 0.007 mm,and the gas channeling path was formed.The outer casing anti-gas channeling device had strong anti-gas channeling performance,and could bear the differential pressure of 35 MPa in the case of compression and sealing.This device was tested in the pay zone cementing of Well Jiaoye 88-2HF and Well Jiaoye 93-2HF.No wellhead pressurizing occurred either well after fracturing.Both the performance test and the field test demonstrated that the outer casing anti-gas channeling device could reduce casing deformation damage to the cementation.The new technique could prevent micro gaps in the cement ring caused by large scale fracturing,so as to prevent gas channeling.This technique could provided a new technical means for anti-gas channeling in shale gas wells.
