Lost circulation prevention and plugging technology
Cosl has four sets of leak-proof technologies: plugging while drilling technology, one-way pressure plugging technology, wall pressure strengthening technology and wall strengthening leak-proof technology. Rapid composite plugging technology, high water loss curing plugging technology, strong network plugging technology, anti-high temperature plugging technology, weak gel plugging technology, chemical gel plugging technology, reservoir fracture plugging technology and strong pressure plugging technology eight sets of plugging technology. Leakage prevention technology can effectively improve the safety density equivalent of formation pressure; The success rate of plugging a leak is more than 90%, and the success rate of pressure is more than 70% for weak layers or cracks, and the pressure capacity can be well improved
