最近,长庆油田在勘探方面取得了新的突破,在陕甘宁盆地打出了一口高产气井,为陕甘宁盆地的天然气勘探展示了良好前景。这是在掩冲带发现的第四口工业气井,而且是目前全盆地日产量最高的一口气井。测试中取得的各项数据,都接近石油工业部颁发的高产气井的标准。高产井位于破碎程度相对较弱的掩冲带东部,属低断块上产气,产层深2500多米。井打在冲断层的上覆盘,气藏是主冲断层旁侧的半背斜圈闭。该构造由地震勘探
Recently, Changqing Oilfield has made new breakthroughs in exploration and has produced a high-yield gas well in the Shaanxi-Gansu-Ningxia Basin, demonstrating good prospects for natural gas exploration in the Shaanxi-Gansu-Ningxia Basin. This is the fourth industrial gas well discovered in the subduction zone and is currently the most productive gas well in the entire basin. The data obtained in the test are close to the standards of high-yield gas wells issued by the Ministry of Petroleum Industry. The high-yielding wells are located in the eastern part of the subduction zone where crushing degree is relatively weak. The well hit the overlying plate of the thrust fault and the gas reservoir is a semi-anticline trap on the side of the main thrust fault. The structure consists of seismic exploration
