尽管地质环境极复杂,天然气工程项目管理部仍实现元坝气田安全高效、增大投资效益的开采模式。对比我国第一个超深高酸性气田——普光气田,元坝气田具有超深、高温、高压、多压力系统、高产、高含硫、气水关系复杂等特点。气藏埋藏比普光气田深1500米左右,平均井深7500米,最深的一口达7899米,以现在家庭住宅层高约3米来比照,相当于2600层高楼,给钻井施工、投产作业带来一系列世界级挑战。元坝气田的地下情况更为复杂。最
Despite the extremely complicated geological environment, the Natural Gas Project Management Department still implements the mining mode of Yuanba Gas Field that is safe and efficient and increases investment returns. Compared with the first ultra-deep and sour gas field in China, the Puguang gas field, the Yuanba gas field is characterized by ultra-deep, high-temperature, high-pressure and multi-pressure systems with high yield, high sulfur content and complicated gas-water relationship. The gas reservoir is buried about 1,500 meters deeper than the Puguang Gas Field with an average well depth of 7,500 meters and the deepest one reaches 7,899 meters. Compared with the current residential area of about 3 meters, it is equivalent to 2,600-storey high-rise buildings, bringing drilling construction and production operations to one Series of world-class challenges. The underground conditions in the Yuanba gas field are more complicated. most
