Abstract: This paper is based on the general situation of the reservoir and engineering of three large dip angle U-shaped wells in Zhaozhuang Coal Mine, combined with the actual data, through analyzing of production results and data of these wells, we found that the gravity separation of gas and water is serious in the extraction process of U-shaped horizontal wells, large amount of water is produced and the intermittent producing problem caused by pump plugging is serious. For the above phenomena and problems, it is necessary to put two wells into use at the same time, vertical well is used to produce water, engineering well is used for gas production, and the high power pump is selected for production. What more, in order to avoid the intermittent type production, we should adhere to the uniform of stability and slow.
