气井生产过程中影响气井产量的主要因素是井筒积液而对于边底水凝析气藏这种矛盾表现得更为突出因此正确预测和及时有效识别出水来源对提高或稳定气井产量以及改善气藏开发效果有重要的意义。以A凝析气藏为研究背景通过产出气中凝析水含量计算生产井产气量、产水量、水气比等生产特征参数变化来确定气井具体的产水类型及井筒积液的来水特征从而正确认识储层构造特征和气水分布关系以利采取有效的控水措施。 During the progress of gas well production, the major factor which influences the gas well production is liquid loading, while as for the gas reservoirs with edge and bottom water, the contradiction is more serious. Therefore correctly predicting and timely and effectively recognizing the sources of water were of great significance for improving and stabilizing the gas wells production and improving the production effect in gas reservoirs. Taking Condensate Gas Reservoir A as the research background, this paper determined the type of gas well water production and the water characteristic of the liquid loading by calculating the water content in the condensate gas reservoir, gas production, water production and water and gas ratio of production wells, by which the reservoir structure and relation of gas and water distribution are correctly identified, and then the effective measures for water controlling can be taken.
