Description
技术领域
本发明属于油田开发用射孔枪技术领域,尤其涉及用于制备TP110PS抗硫射孔枪管的钢管。
背景技术
含硫油气井因富含H2S,极易对井下高强度管材造成氢脆,发生不可预测的脆性断裂,是射孔枪服役环境最严苛的井况之一,当井下服役环境中H2S分压达到0.3kpa以上,需要考虑H2S对管材的破坏作用。由于射孔枪作业过程中,管体破裂、断裂、挤毁,都会导致枪体掉井、卡井,造成极为严重的施工事故,因此射孔枪的安全系数要求较高,对射孔枪管的强度、韧性、抗H2S性能等也提出了极高的要求。出于工艺和安全的需要,枪管必须满足H2S分压0.3kpa以上,枪管材料在一定应力加载条件下,保证满足最长施工时间要求而不发生断裂或裂纹。
常规射孔枪材料,钢级强度基本在110ksi-125ksi,在室温条件下,饱和H2S溶液中,当加载应力达到管体屈服强度的80%时,断裂时间基本不超过15h,断裂形式为延晶界断裂,断口为脆性断口。
根据文献调研和射孔枪管标准对比,目前,专门应用于含H2S井况的射孔枪管材料还未进行开发和应用。
由于目前各大钢管企业还未进行抗硫射孔枪管材料进行研发,油田采用的依旧为普通枪管材料,未对材料在含硫油井中的安全性和使用性做出评价,这对施工安全造成了一定的潜在隐患,对射孔效果造成一定程度的影响。
针对以上问题,有必要研究一种适用于含硫环境石油开采井况,满足油层射孔后枪体不断裂、无裂纹的要求的用于制备TP110PS抗硫射孔枪管的钢管。
