| Abstract: | There are low yield, poor liquid-carrying capacity, easy formation of effusions at the bottomhole and inability to perform normal operation in Changqing Oilfield, the devices and tools needed by the drainage gas-recovery technology of coiled tubing velocity string were developed. The problems of the 38.1 mm coiled tubing hanging, sealing and snipping under pressurization were solved. The structural principle of the operation window of key parts and the hanger was introduced.The technological line of the ope... |
