Abstract

The invention discloses a drilling leaking stoppage small ball and a preparation method thereof, and belongs to the technical field of drilling construction. The drilling leaking stoppage small ball comprises a shell and framework particles, wherein the shell is filled with the framework particles. Gaps between the framework particles and the shell are filled with glass fibers and PVC factice. The framework particles comprise stones. The length of the glass fibers is larger than the particle size of the framework particles. The contradiction that when an inert material is used for leaking stoppage, large particles are prone to bridging but cannot enter the gaps, and small particles are prone to entering but are difficult to bear pressure is solved, the large particles can enter the gaps, stay in the gaps and bear pressure, and the purpose of safe, rapid, simple and reliable leaking stoppage is achieved.

Description

Technical field [0001] The present invention belongs to the field of drilling construction, and in particular, the present invention relates to a drilling plug-in ball and its preparation method thereof. Background technique [0002] The drilling is often encountered by complexity, which affects material consumption, stability of the hole wall, and the quality of mud mass, which will not only increase the cost and construction difficulty, and the situation will also seriously affect construction safety. Complex formation drilling construction is essential, and good plugging technology can make the mud to make full play. Therefore, the borehole plugs can make the key technical guarantee for the drilling and deep diamond. Traditional drilling plugs include inert materials, cement consolidation, chemical slurry, casing tubing, etc., where inert material plugging is most common in construction. [0003] Conventional inert material plugging products mainly include 801 plugging agents,...
