摘要
文章结合大港油田井下作业现场特点,通过研究井控装置FZ18-35防喷器在试压过程中存在的"原试压堵塞器不适合350型采油树井口四通"的具体问题,改进研制适合FZ18-35防喷器与350型采油树井口四通配套的ST18-35试压堵塞器来解决井控装置的现场试压问题,确保现场井控装置的完好,有效降低井控风险以及井喷事故污染环境的风险。
In combination with the site characteristics of the underground work in Dagang Oilfield,we studied the specific problems of the blowout preventer FZ18-35 of the well control device existing in pressure test:the original pressure test blocking device was not suitable for 350 type production tree wellhead.Therefore we improved ST18-35 pressure test blocking device which was suitable for both FZ18-35 blowout preventer and 350 type production tree wellhead to deal with the site pressure test of the well control device to ensure the integrity of the site well control device and reduce the risks of well control and environmental pollution by blowout accidents.
