Characteristics of fluid inclusions and hydrocarbon accumulation mechanism of marine sandstone reservoir:with Silurian asphalt sandstone in central Tarim basin as an example

海相砂岩储层流体包裹体特征与成藏时期——以塔中志留系沥青砂岩为例

Impact on reservoir quality of oil/gas filling into reservoir of asphalt sandstones has been studied by means of laboratory simulation.

通过模拟实验的方法分析了油气充注对沥青砂岩储集性的影响,早期充填沥青少而残余孔隙率、渗透率很低的砂岩,晚期油气仍不能充注,是非储层;早期沥青均匀充填、充填程度高,残余孔隙率、渗透率低的砂岩,晚期低粘度稀油仍能充注,孔隙率、渗透率有大幅度提高,是有效储层;早期沥青充填较均匀,残余孔隙率相对较高,不同粘度的原油充注后,孔渗条件发生明显的改善。

The Silurian asphalt sandstone is widespread in Tazhong area of Tarim basin and mainly found in the upper slope of paleo-uplift and oil-generating basin of Lower Paleozoic, which shows that the widespread asphalt sandstone could be the outcrop of paleo-oil pools in this area.

塔里木盆地塔中地区广泛分布着志留系沥青砂岩,主要分布在古隆起和早古生代生油盆地的上倾方向,表明本区规模巨大的志留系沥青砂岩可能为古油藏露头带。

Based on microscopic examinations, the secondary pores of Jurassic asphaltic sandstone in central Tarim Basin can be divided into 4 types, including quartz and siliciclastic grain boundary dissolution pore, quartz secondary overgrowth boundary dissolution pores, feldspar and volcanic debris dissolution pore, and intergranular carbonate cement dissolution pore.

显微镜鉴定结果塔中地区志留系沥青砂岩次生孔隙可分为石英及硅质岩屑颗粒边缘溶孔、石英次生加大边溶孔、长石及火山岩岩屑溶孔以及粒间碳酸盐胶结物溶孔4种类型。

Gas/source rock and bitumen/source rock comparisons have indicated that,light hydrocarbon C_(6+7) compositions in the Sinian,Cambrian and Ordovician productive formations are almost the same.

遵义后坝奥陶系红花园组生物碎屑灰岩中发现油苗和沥青,经过气/源岩、沥青/源岩对比,震旦、寒武及奥陶系产层轻烃C6+7结构组成基本一致,奥陶系含油苗灰岩轻烃星图与震旦系泥岩、寒武系沥青砂岩星图较为相似,显示红花园组油苗主要来源于震旦系和下古生界过成熟或高成熟海相烃源岩,油气经历了较长距离的运移,得以在奥陶系中保存下来。

Modified asphalt was successfully prepared based on AH-70 bitumen with native rock asphalt modifier,and favorable performance was obtained.

利用天然岩沥青作改性剂,对AH-70基质沥青进行改性,获得了良好的试验效果。

At the same time, it is found that the admixing of the certain rock asphalt can efficiently enhance the performance of mixture.

同时还发现,掺加一定量的岩沥青,可以有效提高混合料的性能,建议在橡胶粒沥青混合料中掺加适量的岩沥青。

Aiming at rheology characteristics of gilsonite modified bitumen,the gilsonite performances of various kind and dosage are compared and analyzed with PG appraisal system through DSR,BBR and Brookfield revolving viscosity tests.

针对岩沥青改性沥青胶结料的流变特性,通过动态剪切(DSR)、弯曲梁流变(BBR)、布氏旋转粘度试验,用PG分级评价体系对不同种类、不同掺量的岩沥青改性沥青进行性能测试与分析。

Performances of gilsonite asphalt binder are compared and analysed when different contents of gilsonite are blended into Korea SK asphalt and Taiwan CPC asphalt.

岩沥青常被用作为沥青路面的添加剂,已在国内外一些工程中得到应用。
