为准确地预测溶蚀孔洞和大型洞穴的发育区带,文章根据溶洞的发育机理,综合应用层位拉平技术、相干体技术和蚂蚁体自动追踪技术恢复了四区的古地貌、古水系和断裂分布,并结合钻井和测井溶洞统计结果将溶洞发育带分为三类:残丘山头、残丘斜坡和残丘洼地,指出了塔河四区溶洞最容易发育的区带:残丘山头和残丘斜坡,尤其是在断裂和水系均发育的区带。综合考虑古地貌、古水系和断裂系统在溶洞发育中的作用,绘制了溶洞发育区带图,很好的解决了储层建模中溶洞的空间分布约束问题。
In order to accurately predict the developmental zones of dissolution caves and large caves, the paper restored the paleogeomorphology, paleo-water system and fracture distribution in the four areas according to the development mechanism of karst caves, the comprehensive application of horizon leveling technique, coherent body technique and ant tracing technique , And combined with the statistical results of drilling and logging karst caves, the development zones of karst caves are divided into three categories: hillsides, valleys and valleys, and the most developed zones of karst caves in the four districts of Tahe are pointed out: Hill slopes, especially in zones where faults and water systems are developed. Considering the role of palaeogeomorphology, paleo-water system and fault system in the development of karst caves, the map of karst cave development zones is drawn, and the problem of constraining the spatial distribution of karst caves in reservoir modeling is well solved.
