致密砂岩气属于非常规天然气资源家族的一员,其储层孔隙度低、渗透率低、随钻录井气测显示弱、气水关系复杂。这些特征,给录测井解释评价带来诸多需要攻关与认识的技术难题。在建南地区首口致密砂岩气勘探开发试验井—建111井,江汉录测井人员于须家河组须六段致密砂岩储层发现并解释典型致密砂岩气层1层厚9.0m,完井测试,日产天然气3 000m3。须六段致密砂岩气的成功解释评价,丰富和验证了现有的录测井致密砂岩气解释评价方法,为下步该地区致密砂岩气开发录测井解释评价积累一定的实践经验。

Tight sandstone gas belongs to an unconventional gas resource.Its reservoir has a low void ratio and permeability.The show effect for gas survey in well drilling and logging is weak and gas-water relation is complicated.All this has brought problems technologically to logging interpretation and evaluation which need to be understood and solved.In the process of exploring and developing the first test well(Jian Well 111) with tight sandstone gas in Jiannan area,Jianghan well logging staff have discovered and interpreted typical tight sandstone gas reservoir of 9.0 m thickness per layer in tight sandstone reservoir of Member Xu 6 in Xujiahe Formation.Output of natural gas a day reaches 3000m3 during well completing test.Success in interpreting and evaluating tight sandstone gas of Member Xu 6 has enriched and checked existing evaluation method,and accumulated some practical experience for well logging interpretation and evaluation in the next development of tight sandstone gas in Jiannan area.
