Big crror may occur in using the productivity analysis of single - phase gas well for condensate well 摘要凝析气井的产能在沿用单相气井的产能分析方法时会产生较大的误差。
Discussion of supercritical carbon dioxide and hydrogen sulfide induced drilling and production accidents in high sour gas well 高酸性气井超临界态二氧化碳硫化氢的相态变化诱发钻采事故探讨
So it is necessary to do it based on the gas well production history so as to avoid economic lows caused by the shut - in 因此，有必要研究根据气井生产史确定藏参数的方法，避免关井给生产带来的损失。
Case correlation study shows that for gas wells without shut - in pressure survey , this method can be used to resolve the reservoir parameters 实例对比表明，对于没有关井测压的气井，可以用该方法反求气藏参数。
Abstract : there is a low - pressure nature gas in the brine well , the casing , well end and pipe are very corrosive because brine is accrued 文摘:盐井伴生有低压天然气,实现加压采输后出现气井套管、井口,输气管线被严重腐蚀的现状。
Finally it concludes that the best guarantee for high production of gas well is preventing reservoir pollution , effective innovation and reasonable use of formation energy 因此，防止储层污染、对储层进行有效改造、合理利用地层能量是获得气井高产的重要保障。
Based on the successful experience of constructing of coalbed methane well , the construction technique is introduced on drilling , well protection , coalbed reconstruction and so on 根据施工煤层气井的成功实践，介绍了有关煤层气井的钻进、固井工程及煤层改造等施工技术。
The result shows that the recovery condition of the cbm well will change with the change of the recovery system , and the permeability of coal reservoirs will also change 研究结果表明，煤层气井工作制度的变化会引起煤层气井采动状况发生变化，导致煤储层渗透率产生波动。
The case study indicates that such a method is more reliable than before , and provides more precise bases for further open flow potential estimation and proration measures implementation 应用实例证明了新方法是比较可靠的，为以后计算气井无阻流量和开采配产作业提供了准确的依据。
Gas well productivity is important is an important method for determination of ripen flow potential and working system , prediction of prediction performance and study of related gas reservoir engineering 摘要气井产能评价是确定无阻流量和工作制度、预测生产动态及其它气藏工程研究的重要手段。
