| 摘 要： | 松辽盆地营城组火山机构类型划分为碎屑岩火山机构、熔岩火山机构和复合火山机构3种。碎屑岩火山机构中火山通道相占9.3%,爆发相占55.3%,喷溢相占29.2%,侵出相占1.4%,火山沉积相占4.8%;火山机构半径为0.5~1.5 km,高度为50~220 m。熔岩火山机构中火山通道相占8.1%,爆发相占23.4%,喷溢相占62.6%,侵出相占5.1%,火山沉积相占0.8%;火山机构半径为1~2 km,高度为200~300 m。复合火山机构中火山通道相占4.9%,爆发相占34.4%,喷溢相占56.8%,侵出相占2.6%,火山沉积相占1.3%;火山机构半径为2~4 km,厚度为300~450 m。亚相控制储层流动单元的规模,碎屑岩火山机构的储层流动单元范围为0.3~1.5 km,厚度小于60 m。熔岩火山机构的储层流动单元范围为1~2km,厚度小于80 m。复合火山机构的储层流动单元范围为1.5~3.0 km,厚度小于100 m。各类火山机构气藏开发时的井距和压裂方案均存在差异。

| Abstract: | According to eruptive scale illustrated by drilling lithology,facies characteristics and seismic data,early Cretaceous volcanic edifices of Yingcheng Formation in Xujiaweizi faulted depression,Songliao Basin were classified into pyroclastic volcanic edifice,lava volcanic edifice and compound volcanic edifice.The facies composition of pyroclastic volcanic edifice was listed as fellows: 9.3% for volcanic vent facies,55.3% for explosive facies,29.2% for effusive facies,1.4% for extrusive facies and 4.8% for volcanic sedimentary facies.The pyroclastic volcanic edifices is 0.5-1.5 km wide and 50-220 m thick.The facies composition of lava volcanic edifice was 8.1% for volcanic vent facies,23.4% for explosive facies,62.6% for effusive facies,5.1% for extrusive facies,and 0.8% for volcanic sedimentary facies.The lava volcanic edifices is 1-2 km wide and 200-300 m thick.The facies composition of compound volcanic edifice was 4.9% for volcanic vent facies,34.4% for explosive facies,56.8% for effusive facies,2.6% for extrusive facies and 1.3% for volcanic sedimentary facies.The compound volcanic edifices is 2-4 km wide and 300-450 m thick.The scale of reservoir flow unit is controlled by subfacies of volcanic edifices.So the scale of reservoir flowing unit is various for each volcanic edifice,pyroclastic volcanic edifice is 0.3-1.5 km in width and less than 60 m in thickness,lava volcanic edifice is 1-2 km in width and less than 80 m in thickness,compound volcanic edifice is 1.5-3.0 km in width and less than 100 m in thickness.So the distance of wells and hydraulic fracturing plan are different in each kind volcanic edifice during the development. |
