South Sichuan gasarea with a lot of gas field water takes Lower Permian Series gas reservoir as main body. Gas field water scaling is a difficult problem in production.
川南地区是以下二叠统气藏为主的气区，产大量的气田水，气田水结垢是生产中的一大难题。

Base on geological structure and reservoir features, the gas reservoir is divided into gasarea and gas-water transition area and the volume method is applied to check gas-in-place.
在对气藏构造、储层综合研究的基础上，将气藏分为气区及气水过渡区进行了容积法储量复核。

The gas-pool formation and distribution are controlled by hydrocarbon source from oil-measure and coal-measure strata which constitute a dry gasarea of marine over-mature carbonate rock.
