【摘要】：深井、超深井尾管固井作业中施工压力高,井口固井水泥头的操作难度和安全风险较大,为此,在对常规水泥头机械结构进行改进的基础上研制了远程控制水泥头,结合水泥头机械结构的特点设计了气动驱动系统,并采用无线通讯控制技术进行气动驱动系统远程操控,从而实现远程控制水泥头投塞、投球和固井管汇通断。室内测试结果表明,远程控制水泥头满足现场试验要求。远程控制水泥头在某地热井固井作业中进行了现场试验,通过远程控制水泥头控制终端,顺利完成了各项功能动作,达到了设计使用要求。远程控制水泥头的成功研制,为井口高压环境下固井作业安全提供了保障。
[Abstract]:The operation pressure is high and the operation difficulty and safety risk of cementing head are high in deep well and ultra-deep well tail pipe consolidation operation. For this reason, a remote control cement head is developed on the basis of improving the mechanical structure of conventional cement head. Combined with the characteristics of mechanical structure of cement head, the pneumatic drive system is designed, and the remote control of pneumatic drive system is carried out by wireless communication control technology, so as to realize remote control of cement head plug. The laboratory test results show that the remote control cement head meets the field test requirements. The remote control cement head is tested in the field during the cementing operation of a geothermal well, and the cement head control terminal is remotely controlled. The successful development of the remote control cement head provides a guarantee for the safety of cementing operation under the high pressure environment of the wellhead.
