Plunger lift in Tuha Oil Field

Plunger lift was first applied in Tuha Oil Field to solve the problems of high water-cut and low-producing gas lift wells. And obvious effect of production increment was obtained in the field test. The methods for the plunger liftsystem analysis and well completion design are introduced, and a statement is made on the selection of the accessory tools and the optimization of the string as well as the surface equipment matching. The result of the field test on a lowproducing well is evaluated. The success of the plunger lift test in Tuha Oil Field provides a new means for solving the problems of the low producing wells in this oil field.
