This invention relates to a leakage-stopping composite used during well drilling. It is made of paper fibre, granular limestone and calcium lime. When compounded with water to form pulp and filled into a leaking stratum, it can form a plug to prevent slurry from leaking out. By using fracturing-acidifying method, the plug can be cleared away, thereby attaining the purpose to extract oil and gas from the once blocked strata. |
