摘要: 龙岗礁滩气藏为高温、超深、中高含硫气藏，试采期间气井普遍产水，受水侵影响气井产量降低，井筒携液能力变差，甚至因积液严重而关井，影响气井正常生产，现有排水采气工艺难以满足实际生产需要。根据气藏气井超深、中高含硫、产液量大、管柱有封隔器以及消泡难等特点，提出采用油管穿孔配合压缩机气举排水采气工艺，并制定了工艺施工步骤。该工艺不需要改动生产管柱，无需井下气举工具，有效地解决了设备抗硫、耐高温等问题，为气藏排水采气的优先选择工艺。在龙岗001-18 井进行了首次试验，通过优化注气压力、生产制度等工艺参数，实现了超深、高温、中高含硫气井排水采气，气井成功复产，降低了系统内其他生产井的水侵风险，可为同类气藏超深气井排水采气工艺提供借鉴。

Abstract: The Longgang reef gas reservoir is a high-temperature, ultra-deep, mid-high-sulfur containing gas pool. During production test, most of gas wells produced water. Because of water invasion, production of gas wells decreased, the liquid carrying capacity of the wellbore becomes poor, even leading to gas well shut-in due to severe accumulation of fluid, hence affecting the normal production of gas wells. The existing drainage gas recovery technology cannot satisfy the actual production. According to the characteristics of gas wells being ultra-deep, mid-high sulfur content, large liquid production, pipe string having packers on it and difficulty in defoaming, etc. The drainage gas recovery technology is presented by perforating tubing and by gas lift using compressor, and the operation procedures is established. This technology need not to modify the production string or to run in gas lifting tools, effectively addressing the problems of equipment anti-sulfur and high temperature-proof, so it is the preferred technology for drainage gas recovery for gas pools. This technology was first tested in Well Longgang 001-18, optimizing the parameters of gas injection pressure, production system, etc. The drainage gas recovery is successful in ultra-deep, high temperature and mid-high sulfur containing gas wells. The successful resumption of gas well production reduces the risk of water invasion in other producing wells within the system. This method can be a reference to drainage gas recovery technology for ultra-deep gas wells in similar gas pools.
