摘要
在碳酸盐岩储层古潜山风化岩溶型储层,发育多重岩溶缝洞系统、非均质性较强,采用常规取心技术难获得理想的岩心收获率。文中总结分析破碎碳酸盐岩取心技术难题并结合碳酸盐岩地层取心经验,形成了一套适应性强的破碎碳酸盐岩地层取心技术,并在一些破碎碳酸盐岩地层取心推广应用上获得了良好效果。
The carbonate formation has the characteristics of abundant solution cavities and fractures system and strong heterosphere in China area. When coring in these formation, it is easy to induce core jamming, blocking and grinding, so it is difficult to achieve high core recovery. In this article, the existent problems in coring in these formations were summarized, and based on the successful coring experiences in the fractured carbonate formation, the coring technology in the fractured carbonate formation is come into being. With the technology, good effects have been obtained in the fractured carbonate formation coring applications.
