| Abstract: | In this paper,the quantitative evaluation of on-the-spot detections of the damage by drilling and completing operation for the fracture-pore type gas reservoirs in eastern Sichuan which mainly belong to Middle carboniferous Series and the Lei 1-a pore type gas reservoirs in central Sichuan are done by using transient testing method, the gas productivity after the damage having been removed is forecasted and some proposals for the type and scale of acidizing technology from now on are made on the basis of evaluating acidizing results. |
