储层地震反演在深层油气藏勘探中的应用

Application of seismic inversion in deep oil and gas reservoirs exploration

近年来,松辽盆地在下白垩统及以下层系发现并探明9个深层油气田。盆地背部大庆油区有3个气田,盆地南部吉林油区有4个气田、2个油田,该盆地深层以气藏为主,油藏为辅。深部储层一般具有较大的储集空间和油气储量,深部储层预测方法研究意义重大。结合松辽盆地的哈尔金地区深层油气藏勘探,介绍了储层地震反演的基本理论,并以松辽盆地哈尔金地区为例详细阐述了Jason地震反演软件在深层油气藏中的应用。

Nine deep seated oil gas fields are discovered and proved in lower Cretaceous and the under series of strata of Songliao basin. Many scholars do many studies about deep seated oil gas. The studies are based on the point of temperature , occurrence and distribution, material base, stability of deep oil and gas, key factors of controlling reservoir physical properties, effected on reservoir formation by abnormally high pressure and analysis of oil geology of typical deep seated oil gas. Deep reservoir has major storage space and oil and gas reserves. Studies of deep reservoir prediction method are great valuable. Combining deep reservoir of Haerjin of Songliao basin and making Haerjin as an example, this article introduces the basic theory of seismic inversion and elaborates Jason seismic inversion software apply to deep reservoir in detail.
