生物碎屑灰岩

塔中地区生物碎屑灰岩储层分析与评价

Analysis and Evaluation of Bioclastic Limestone Reservoir in the Central Region of Tarim Basin

自下而上的地层序列是火山岩系-火山碎屑灰岩-生物碎屑灰岩；

Special stratigraphic sequence ( from bottom upwards ): volcanic rocks , pyroclastic limestone and bioclastic limestone ;

矿石类型主要为凝灰质生物碎屑灰岩等，金品位高。

Tuffaceous-bioclastic limestone is the main type of ore-bearing rock .

托索湖&花石峡礁带的主体由块状的礁相灰岩和生物碎屑灰岩所组成；

The reef island belt from Tusuo Lake to Huashixia is mainly composed of massive reef limestone and bioclastic limestone .

本文研究表明，大中旺地区油气主要分布在沙一段下部的生物碎屑灰岩和云质灰岩段（特殊岩性段），储层溶蚀孔隙发育；

Several points can be concluded for the area from this paper study : ( 1 ) Hydrocarbon mainly occurs in the lower interval of bioclastic limestone and dolomitic limestone ( the special lithologic interval ) in Es_1 Member , in which solution pores well developed ;

在论证中采用了生物碎屑定量统计、灰岩酸不溶残渣分析、模拟水槽试验等方法。

In the course of demonstration , the methods such as quantitative statistics of different bioclasts , the acid-unsolvable residue analysis of limestones and the simulated experiments in the water flute were used .
