大民屯凹陷西侧中南段沙四段储层特征研究
|
摘要
地震、地质相结合,利用高精度三维地震储层反演技术和储层地质评价技术,对大民屯凹陷西侧中南段古近系沙四段低渗透储层特征进行了系统分析,确定了储层的产状、岩石学特征、物性特征及微观特征等。分析认为该套储层为中孔低渗透、低孔超低渗透储层,针对微裂缝的存在,并结合油层改造措施,使这套储层仍具有较大的勘探和开发价值。研究内容对指导该区的下一步勘探以及同类储层的含油气评价都具有一定的指导和借鉴作用。
Paleogene Es4 low permeability reservoirs in the mid-south section of west Damintun Depression have been systematically analyzed by combining seismic and geological data and using high-resolution 3D seismic inversion and geological evaluation techniques. The occurrence, petrology characteristics, petrophysical property and microscopic feature of the reservoirs are understood. It is thought that these reservoirs belong to medium-porosity low-permeability and low-porosity ultra-low-permeability reservoirs, but the existence of microfissure combining with reservoir stimulation measures makes these reservoirs still have big worth of exploration and development. This study can be referred to in exploration in this area and in petroliferous evaluation of similar reservoirs.
