Abstract
So far Puguang Gas Field is the largest marine gas field in China, which is characterized by high H2S content, ultra depth, strong heterogeneity of reservoir and complicated gas-water relations. There was no precedent for successfully exploiting analogous gas fields in China. During the development and construction of Puguang Gas Field, design of development wells were optimized and some wells with high productivity were breeded via real-time tracking of data of new wells, continuous research on sedimentary microfacies, reservoir prediction and gas-bearing prediction. As a result, a series of design techniques of high effective wells are formed gradually, which provide strong technical supports for high efficient development of Puguang Gas Field.
