摘要
为了评价徐家围子断陷火山岩圈闭的含气性 ,综合考虑了火山岩圈闭的各种成藏条件的影响 ,利用灰色关联方法建立了火山岩圈闭含气性的综合评价方法 ;应用该方法 ,根据徐家围子断陷 31个火山岩圈闭成藏条件特征 ,综合评价了该断陷火山岩圈闭的含气性 ;结果表明 ,Ⅰ类火山岩圈闭 18个 ,Ⅱ类火山岩圈闭 9个 ,Ⅲ类火山岩圈闭 4个 ;研究结果对松辽盆地北部深层天然气勘探具有参考价值 .
To evaluate the gas-bearing traps in Volcanic rocks, this paper comprehensively cousidered the effects from all formation couditions of a gas reservoirs to a trap in volcanic rocks, established an evaluation method on the gas-bearing of traps in volcanic rocks by the method of gray connection. According to the formation conditions of gas reservoirs in 31 traps of volcanic rocks in Xujiaweizi depression, this paper comprehensively evaluated their gas-bearing. The results indicate that there are 18 gas-bearing traps in Volcanic rocks to be good, 9 to be moderate, and 4 to be bad.
