In line with lfuid accumulation in gas wells in Sulige Gas Field, the Jianghan Machinery Research Institute and Oil&Gas Research Institute of Changqing Oilifeld jointly carried out the research work on small diameter pipe hanging+intelligent injection agent, and successfully performed the work of hanging 3 300 m of small diameter pipe, intelligent injection agent and pulling out of hole under pressure. The success of this test provides a new way for experimental study on drainage gas recovery by long-term or intermittent injection of foaming agent in small diameter pipe and for increasing the production of gas wells;this has also accumulated experiences in pulling coiled tubing out of hole under pressure.
