摘要:

依据岩心资料,对渝东南地区龙马溪组页岩裂缝进行了较为详细的识别,统计了岩心裂缝基本参数并计算了裂缝密度,确定了用裂缝特征参数(裂缝基本参数和裂缝密度)描述裂缝发育特征的方法|并以渝页1井为例,综合镜下微观裂缝、岩心宏观裂缝、页岩裂缝基本参数以及裂缝密度,对渝东南地区下志留统龙马溪组海相富有机质黑色页岩裂缝发育特征进行了较为详细的描述。同时,对影响页岩裂缝发育程度的因素进行研究,定性或半定量地确定了页岩裂缝发育特征与岩石脆性矿物含量的关系,并分析了富有机质海相页岩的裂缝发育程度与有机碳含量之间的关系。结果表明:①石英、长石、方解石等脆性矿物含量较高且黏土含量较低的页岩裂缝较发育|②有机碳含量在很大程度上与富有机质海相页岩裂缝发育程度存在正相关关系,并且有机碳含量越高,裂缝密度越大|③可据有机碳含量将裂缝发育程度分为3类:较差、一般和较好。

Abstract:

Based on core data,a detailed identification was carried out on the shale fracture in Longmaxi Formation in southestern Sichuan.Statistics of core fracture basic parameters were done and the fracture density was calculated.A method was established which apply fracture characteristic parameters to determine the fracture development characteristics.Taking Yuye 1 well as an example,combined with the microscope observation of micro crack,macroscopic core crack,shale fracture and fracture density,a detailed description was carried out on the fracture development characteristics of the organic-enriched marine black shale in Longmaxi Formation.Also,the influencing factors of shale fracture development degree are studied,the relationship between shale fracture development characteristics and the rock brittleness mineral content was determined qualitatively or semi-quantitatively and the relationship between the fracture development degree of organic-enriched marine shale and the organic carbon content was analyzed.Results show that:(1)Shale with high content of quartz,feldspar,calcite,brittleness mineral and low content of clay is easy to produce fractures|(2)To some extent,the TOC has a positive correlation with the fracture development degree of organic-enriched marine shale.The higher the TOC,the larger the fracture density|(3)The fracture development degree can be divided into three categories according to the TOC:Poor,normal and good.

Key words: Southeast of Sichuan, Longmaxi Formation, Brittle mineral, Crack characteristic, TOC
