摘要:
 

常规内防喷工具功能单一，不能与其他工艺进行配合作业；带压时不易操作且反复开启容易失封。超级安全阀内防喷技术在地面通过三通道

液压控制操作井下全通径球阀开关，可与连续油管、测井电缆、试井钢丝等配合进行完井测试；预置充氮压力可推动球阀剪切连续油管等缆绳，实现管柱内封井；化学注入通

道接入井场的化学注入设备，能够有效解决稠油井堵塞井口的问题。该技术在伊拉克鲁克10区块Eridu1井配合地层测试、连续油管酸化以及生产测井等施工，实现了一套测

试管柱与多种工艺联作，应用效果良好。超级安全阀内防喷技术为安全高效试油作业提供了技术支持。

Abstract:
 

onventional internal blowout preventer has single function and can′t cooperate with other

processes; It is difficult to operate under pressure and easy to lose sealing when it is opened repeatedly. Super safety valve internal blowout

prevention technology controls and operates downhole full bore ball valve switch through three channels on the ground, which can cooperate with coiled

tubing, logging cable and well testing wire for well completion test; The preset nitrogen filling pressure can push the ball valve to shear the coiled

tubing and other cables to realize the well sealing in the string; The chemical injection channel is connected to the chemical injection equipment

 in the well site, which can effectively solve the problem of heavy oil wells blocking the wellhead. The technology has been applied in well Eridu1

of Ruk 10 block, Iraq, in combination with formation testing, coiled tubing acidizing, production logging and other operations, realizing the joint

operation of a set of test string and various processes, and the application effect is good. Super safety valve blowout prevention technology

provides technical support for safe and efficient well testing operation.
