摘要
尽管国内外针对渗漏性漏失有过一些研究,但到目前为止,仍没有系统的针对裂缝性地层漏失的堵漏配方及规律性的研究,同时目前仍没有有效地解决裂缝性地层的漏失问题。在广泛调研国内外堵漏技术的基础上,利用自行研制的DL-A高温高压堵漏仪,对裂缝性漏层堵漏配方进行了研究,找到了裂缝性地层堵漏的一般规律,同时确定了较为理想的堵漏配方,为裂缝性漏层的堵漏技术奠定了基础。
Although studies on seeping loss of mud have been done all over the world,a systematic study on mud losses in fractured formation is not yet found,and a solution for lost circulation in fractured formations is yet to be provided.An extensive study was conducted on lost circulation in fractured formations using a self-made HTHP lost circulation tester,DL-A,based on a comprehensive review of lost circulation control technology both used in China and abroad.A general rule of lost circulation control in fractured formations was found and a relatively ideal lost circulation control fluid formulation for controlling mud losses in fractured formations was presented.
