Abstract

The invention relates to the technical field of leakage stopping agents, in particular to an efficient waterproof leakage stopping agent. The efficient waterproof leakage stopping agent comprises, by weight, 30-50 parts of calcium sulphoaluminate, 25-35 parts of sepiolite, 10-20 parts of lithium chloride, 15-25 parts of talcum powder, 5-10 parts of polyacrylamide, 6-12 parts of coconut root-bark, 6-10 parts of shells, 2-6 parts of teflon and 7-15 parts of sodium tripolyphosphate. The efficient waterproof leakage stopping agent is efficient, capable of stopping cracks rapidly, significant in waterproof leakage stopping effect, high in strength, capable of remaining on a leaking layer well and good in fluidity, and a plugging layer has high pressure bearing capacity within short time.

Description

technical field [0001] The invention relates to the technical field of leak-stopping agents, in particular to a high-efficiency waterproof leak-stopping agent. Background technique [0002] Lost circulation is one of the factors that have the greatest impact on drilling speed and drilling cost in various complex situations, and it is a difficult problem that plagues oil and gas drilling. Once lost circulation occurs, it not only needs to consume a large amount of drilling fluid materials and plugging materials, but also prolongs the engineering time, increases the cost of development, and even causes downhole accidents such as stuck drill, buried drill and scrapped the whole well. At present, there are many plugging agents with different characteristics in the domestic market, some of which are plant fiber plugging agents mainly composed of cotton fibers, peanut shells, walnut shells and other plant fibers; some are mainly composed of asphalt-limestone mixture, potassium hum...
