摘要:

准噶尔盆地吉木萨尔凹陷芦草沟组储层夹于互层分布的优质烃源岩层系中,岩性多样,非均质性强,物性总体较差,以微米—纳米级孔隙为主,但孔隙中普遍含油。 该组上段和下段各存在 1 套非常规“甜点体”,具有典型的致密油特征,而针对常规油气藏建立的实验分析技术难以适应和满足致密油进一
步勘探开发的需求。 运用多参数配套联测、致密油岩心洗油方法探索、致密油岩心孔渗和润湿特性测试以及碳酸盐类矿物染色技术等针对性的实验分析技术,来研究烃源岩特性以及储层岩性、物性和含油性等致密油的典型特征及其内在相关性。

Abstract:

 The reservoirs of Lucaogou Formation in Jimsar Sag of Junggar Basin distributed alternately in high quality source rock layer series. There are two sets of unconventional reservoirs in the upper and lower segments and show typical tight oil characteristics of various lithologies, strong heterogeneity and micron-nanometer pore with oil. The original experimental analysis technology for conventional reservoirs is not satisfied for the need of further exploration and development of tight oil. Based on targeted experimental analysis technology, such as coordinated measurement of multi-parameter, exploration of wash oil, measurement of porosity-permeability and wettability of tight oil core and staining technique of carbonate minerals, this paper studied the typical tight oil characteristics of lithologies, physical properties, oiliness and their inherent correlation. The new achievements not only provide aboundant experimental materials to deepen geological understanding for the tight oil of Lucaogou Formation in the Jimsar Sag, but also effectively promote the exploration and development in this area.

Key words:  experimental analysis technology, tight reservoirs, Lucaogou Formation, Permian, Jimsar Sag, Junggar
