排水采气方法的优选 摘 要:排水采气是封闭型水驱气藏生产中常见的采气工艺，由于地层水和天然气中的凝析水的影响常会造成气井井筒的积液，会对气井的生产效能产生比较大的影响。在国内外多年的开发实践基础上，逐渐形成了包括“优选管柱、气举、泡沫排水、机抽、电潜泵、射流泵”等六套比较常用的排水采气工艺。 在加强有水气藏勘探开发的同时，为提高和维持有水气藏的产量和提高有水气藏的最终采收率。目前，国内外主要还是采用上述六套较为成熟的人工举升工艺。随着对有水气藏勘探开发的技术创新，人们开始对不同地质构造的气藏的排水采气工艺进一步细化。与此同时，人们对天然气的需求量空前上涨，对天然气开发技术人员提出更高的要求。技术人员一直致力于寻求最经济、最节省时间、最能提高开采效率的排水采气方法，达到低投入高产出的目的。 将不同的排水采气工艺实施于同一口气井，它所产生的效果是不同的，要是把同一种工艺实施于不同的气井，其效果也不一定相同。不同的排水工艺有它自身的优点和缺陷，不同的有水气藏的地质构造特征也不尽相同。所以只有在兼顾各工艺特点和各气藏本身情况的前提下才能做到真正的优化做到用最少的劳动消耗与投入来获得最多的油气产量。 关键字：排水采气；工艺技术；选择 Methods of Drainage Gas for Selection Abstract: Drainage gas is water flooding closed the common gas reservoir gas production process, the formation water and gas condensate in the water often caused by the impact of the wellbore fluid, gas well production performance will have a relatively large impact. Practice at home and abroad on the basis of years of development, gradually formed, including the preferred column, gas lift, foam drainage, machine pumping, electric submersible pumps, jet pumps and other six sets of commonly used drainage gas technology. In strengthening the water, while gas exploration and development, to improve and maintain water production and increase gas reservoir water ultimate recovery of gas reservoirs. At present, mainly at home and abroad using the above six sets of artificial lift technology is more mature. With the water gas exploration and development of technological innovation, people began to different geological structure of the drainage gas gas technology to further refinement. At the same time, it is the unprecedented rise in demand for natural gas, natural gas development and technical personnel for higher demands. Technicians have been committed to seeking the most economical and save time and most can improve the efficiency of the drainage gas extraction method, to achieve the purpose of low-input high output. Different implementation of the drainage process gas wells in the same breath, the effect it produces
