The Research of Waterproof Used on Mudstone

Article Preview

Abstract:

The paper launched a study of waterproof material for mudstone in gas drilling. The adhesion with rock surfaces and water resistance of four synthetic waterproof materials were experimentally evaluated. The results showed that the four synthetic waterproof materials had a good adhesion to the surface of the rock, which could meet operational requirements in the vertical plane. The synthetic waterproof materials had excellent waterproof property, and could withstand immersion in water of more than 72h.
