摘要
四川盆地川西坳陷陆相致密碎屑岩油 /气储层具有致密、低孔渗、薄层交互、多层叠置和强非均质性的特点。长期以来 ,这种油 /气藏的勘探开发一直是世界性难题。近年来 ,积极推广应用新技术、新方法 ,以新思路、新认识指导勘探开发 ,特别是 2 D/3D井间多井约束地震地层反演技术的开发和推广应用 ,配套和完善了川西致密非均质气藏描述技术。多井约束地震地层反演利用高精度三维地震资料 ,结合测井、地质、钻井、测试等资料 ,在研究确定气藏分布范围、空间几何形态描述、储集参数反演。
The detritus oil and gas reservoir in continental depressed basin in the west of Sichuan are characterized by the compatibility, low porosity and permeability, alternation between thin and thick layer, multi zone stack and intensive inhomogeneity. For a long time, the exploitation and development of the reservoir of this type has been a world wide problem. In recent years, the development of the new technology and the new method, especially, the development and application of 2D/3D interwell technology maks the descriptive technology of the tight heterogeneous gas reservoir in the west of Sichuan become more systematic and perfect. Resorting to the high resolution seismic data and the drilling, surface geology, well logging and testing data, we have acquired some good applications in determining the distribution of the gas reservoir, describing the spatial geometrical shape, inverting the reservoir parameter, studying the sedimentary fancies and reservoir inhomogeneity and predicating the prolific zone etc.
