高温高压高含硫超深井射孔酸化测试应用实践

Perforating Acidizing Testing Oilfield Application of Super-Deep Well With High Temperature,Pressure And Sulfur

针对WB1井井深、高温、高压、高含硫、井筒承压能力有限等情况,成功实现了以RTTS封隔器为主的射孔酸压测试联作施工。酸化过程中,加重液体密度高达1.8g/cm3,创造了储层改造中液体加重密度最高,RTTS封隔器测试管柱在高温、高含硫、井口高压90MPa以上连续6.5h施工的新记录,为类似超深井的射孔酸压测试提供了借鉴与参考。

For situations of deep, high temperature, high pressure, high content of sulfur and low bearing strength of well bore of WB1 well, the Perforating-Acidizing-Testing combination process had been successfully carried out with RTTS packer. The heavy fluid density in acidizing treatment is 1.8 g/cm3 created the new record in stimulation treatment with most high density, which RTTS test string had been continue resisted the above 90 MPa high pressure in high pressure and high sulfur content environment, and which can provides beneficial references for the stimulation of similar super-deep well.
