Experimental Study of High-temperature Resistant Cementing Materials in Geological Exploration Drilling Tools

摘要

As the main carrier for the protective casing purposes, cementing material is an important part in cementing design. In order to obtain a high temperature and high pressure resistant cementing material with low elasticity, we investigated on the high-temperature resistant cementing material used in geological exploration drilling materials to seek better cementing material for fulfilling requirements of high-temperature, and to find the best formula using orthogonal test. With compositions of the material in different proportions, this article investigated performances of the cementing material, as thickening time, loss of water, and compressive strength. By comparison, high-temperature resistant cementing materials experimental technology program has been finally estimated, and the composition ratio of the components are determined.
