摘要
针对沙门子地区深层气藏成藏问题,运用钻井、测井、试油、分析化验等资料,对该区清水河组构造、沉积、储层和成藏模式进行研究。结果表明:清水河组气藏深层断裂发育,匹配良好,储集体主要为三角洲前缘水下分流河道砂体,孔隙度为15.6%,渗透率为8.96×10^(-3)μm^2,属于中—低孔、渗储层,气藏类型为构造-岩性气藏。气藏聚集和成藏的有利因素为靠近富烃凹陷、具有良好封盖条件、晚期成藏、良好的输导体系和发育孔隙型储层。研究为该区有利目标区进一步勘探开发奠定了坚实的基础。
Drilling,logging,oil testing,test and other data are used to study the structure,deposition,reservoir and accumulation of deep gas reservoir in Shamenzi. Research shows that the deep Qingshuihe gas reservoir with well-developed faults and favorable configuration is considered as a mid-low porosity and mid-low permeability structural-lithologic gas reservoir,the reservoir body mainly consists of delta front underwater branch channel sandbodies,reservoir porosity is 15. 6% and reservoir permeability is 8. 96×10^(-3)μm^2. The main controlling-factors of gas reservoir accumulation include near hydrocarbon-rich depression,favorable sealing conditions,late accumulation,favorable migration system and development of porous reservoir.
