摘要

火成岩是松辽盆地断陷层天然气勘探的主要目的层,应用岩性、岩相和地球物理特征,综合研究长岭断陷火成岩特点,预测火成岩的分布。与沉积岩相比,火成岩以地震波速高、密度大、电阻率大和地震波吸收能量大为特征,其主要受深大断裂控制,沿断裂成带、成环分布;火成岩岩相类型有:喷发相、溢流相、火成岩坡积相,尤以溢流相最为发育;储集空间为孔隙与裂缝、溶孔与裂缝组合,裂缝为孔隙与孔隙之间的连通喉道。火山岩活动往往伴随断裂带的发育,而断裂带的活动又控制着地层的岩性和分布,为局部构造的发育和发展提供了良好的条件,也为圈闭的形成创造了有利条件。构造运动和后期改造是控制油气藏的主要因素,断裂的发育程度控制油气藏的分布。
Igneous rocks are the main exploration targets for natural gas in the fault-depression of Songliao basin. The features of igneous rocks are studied synthetically by their lithology, facies features and geophysical features, and the distribution of igneous rocks is predicted. Comparing to sedimentary rocks, igneous rocks are of high seismic velocity, high density, high resistivity, and high absorption of seismic energy. They distribute in belt or ring along deep-great faults. The litho-facies of igneous rocks are eruptional, outflow and slopping, mainly outflow facies. The reservoir space is the assemblage of pore and fracture, dissolving pore and fracture. Fractures are the connecting path between pores. The volcanic activity often accompanies by fault development, and fault development controls the lithology and its distribution, and these offer a good condition for local structure development and formation of traps. Structural movement and the reconstructure in late period are the main factors to control reservoirs, and the faults control reservoir distribution.
