Prediction of water breakthrough time for gas well in Luntai condensate gas field, Shaya uplift, Tarim Basin

 Locating in the eastern Yakela fault of the Shaya uplift of the Tarim Basin, the Luntai gas pool is a condensate gas pool with bottom water. Water breaks through severely since production; hence the accurate prediction of water breakthrough time is critical for guiding development. Based on data from watered well, by means of Sobocinaki-Cornelius method, the relationship between dimensionless coning height and dimensionless coning time is corrected. The error between predicted and actual water breakthrough times in watered well L5 is 9.24%. The water breakthrough time in well L2 is predicted as 12 years, and the rationality of the result is analyzed.
