| 摘 要： | 针对长岭火山岩气藏地质条件的复杂性,为了合理部署设计水平并,实现储量高效动用提供依据,运用动静结合的方法,以火山喷发旋回为基础,以标志层为界限,以地震剖面上可连续追踪为手段,结合测井曲线不同组合特征及试采井气体组份变化,刻画出长岭火山岩发育上下两个期次的岩性系列、九个火山岩体。其中,上部四个酸性含气火山岩体互不连通独立成藏,是下一步开发评价的重点目标区。在经后期多口实钻井,证实了这种动静结合岩体刻画的方法较为可靠,这对其它同类火山岩气藏的开发具有重要的指导意义。 |

| Abstract: | To realize the effective employment of Changling volcanic reservoir reserves and improve productivity of single well, based on volcano eruption cycles research with lithology mark layer for boundary, by means of seismic profile, combined with different assembled characteristics of well logging curves and variety gas composition of tested well and using static and dynamic combination method, 2 periods volcanic lithology series and 9 volcanic bodies of volcanic development in Changling were identified including upper 4 gas acidic volcanic rock developed independently. Each is not connected, which were confirmed as key object zone to develop. The consideration of volcanic distribution and connectivity was basally reliable with prove of latter development wells, which will has significance guidance meaning for the development of similar volcanic reservoir. |
| Keywords: | Changling gas field volcanic static combination with dynamic rock-body depiction connective estimation |
