为了证明用获得的高分辨率地震图像去监测流体饱和度变化的可能性,对天然裂缝性储层进行了时间推移井间地震观测。本次实验是在瑞典Fjallbacka的Chalmers干热岩(HDR)地热研究基地进行的,它横穿了约450m深处的结晶岩中的裂缝性储层。虽然被论证的测量技术打算应用于油藏,但由于该地热储层与天然裂缝性油藏具有相似性且更易于进行工作,因此,此次实验还是选定了Fjallbacka试验基地。对Fjallbacka干热岩进行研究的目的是强化天然裂缝并开发高渗透率裂缝性储层进行热
In order to prove the possibility of monitoring the change of fluid saturation with the acquired high-resolution seismic images, time-lapse crossover seismic observations of natural fractured reservoirs were carried out. The experiment was conducted at the Chalmers Dry-Hot-Rock (HDR) Geothermal Research Base in Fjallbacka, Sweden, which traverses fractured reservoirs in crystalline rocks about 450 m deep. Although the proposed measurement technique is intended for use in reservoirs, the Fjallbacka test site was selected for this experiment because of its similarity and ease of work with natural fractured reservoirs. The purpose of the study on Fjallbacka dry hot rocks is to strengthen natural fractures and to develop high permeability fractured reservoirs for heat
