Productivity Well Testing Technology for Low Permeability Condensate Gas Pool

It's difficult for Pucheng low permeability condensate gas mpl to apply to conventional pro-ductivity well testing technology. In order to this problem, experiments have been done for newer well testingtechnology in three ways- (1)To use gas opl non-stable flow theory to instruct productivity well testing. (2)Torecommnd LIT method in China. (3)To use closed in recovery instead of productivity well testing. The resultspoint out the first two have better effects, but the relative error of bettom hole f1uid storage is from 6 to 17 per-cent, the average of the three is only 2 percent. At the same time, experiment studies in scene make clear closed inrecovery time law. Therefore a complete set preductivity well testing technology has been researched, the applica-tion achieved benificial result in the last years.
