摘要:
 钢丝试井作业普通防喷堵头密封级数少、安装紧固扭矩大、密封效果差、缺少仪器捕捉功能、磨损防硫钢丝。采取增加一级密封压帽和盘根、将73025 mm TBG 平式油管扣型改为Tr75×4扣型、丝扣缠上聚四氟乙烯带密封更改为双道“O”圈密封、增加卡瓦捕捉器和保护衬套等措施，研制出一种新型钢丝作业防喷堵头。室内承压试验和捕捉试验成功后，先后选择0～15 MPa井实测30多井次，均获一次成功。2019年大港油田512井次的实际应用表明，新型钢丝作业防喷堵头安全可靠，紧固扭矩降低15倍，材料消耗降低5倍，工作效率提高一倍以上，完善了钢丝试井作业工艺，对指导现场试井工作具有一定意义。
Abstract:
 The common blowout plug in the steel wire well test operation has few sealing stages, large installation tightening torque, poor sealing effect, lack of instrument catching function and wear of sulfur resistant steel wire. A new type of blowout plug for steel wire operation has been developed by adding onestage sealing and packing, changing the 73025 mm TBG flat tubing thread type to Tr75 × 4 thread type, changing the Teflon tape sealing with screw thread to twoway “O” ring sealing, adding slip catcher and protective bush. After the success of indoor pressure test and capture test, more than 30 wells of 0~15 MPa have been selected for field test, all of which have been successful for the first time. The practical application of 512 well times in Dagang Oilfield in 2019 shows that the new type of steel wire operation blowout preventer is safe and reliable, the tightening torque is reduced by 15 times, the material consumption is reduced by 5 times, and the working efficiency is increased by more than one time. This plug improves the performance of steel wire well test operation technology, which has a certain significance for guiding the field well testing.
