| 中文摘要: |
| 针对阜新盆地浅层致密砂岩气成藏条件,在对8口井砂岩储层测试数据的分析基础上,研究了沙海组三段砂岩储层物性和沉积-成岩特征。认为阜新盆地沙海组三段砂岩储层为浅层致密砂岩储层,埋深<1500 m,孔隙度<10%,渗透率<1×10-3μm2;成岩作用控制沙海组三段砂岩的物性特征,沙海组三段砂岩主要经历压实作用、碳酸盐胶结作用和碳酸盐溶解作用,成岩阶段主要处于晚成岩A期。从而指出沙海组三段浅层致密砂岩储层适合储集来自周围气源岩生成的天然气,是盆地浅层致密砂岩气的有利勘探层位。 |

| Study of test data of sand reservoir from 8 wells and physical property and sedimentary-diagenesis of K1sh3 directed to formation and reservior condition indicate that the K1sh3 reservoir is a shallow tight sandstone reservoir in Fuxin basin with buried depth of < 1300m and porosity of <M10% and permeabilty of <1×10-3μm3.Diagenesis controls physical property of K1sh3.The K1sh3 reservoir was exposed to compact,cementation and dissolution of carbonate.The diagenesis is dominated by late diagencsis.The shallow tight K1sh3 is favorable for reservoir of gas from the surrounding source of natural gas thus is the gas exploration target. |
