Abstract

In the process of measure operation for oil and gas wells, downhole tools may get stuck, which not only delays the construction period, but also increases the operation cost. This paper discusses a kind of degradable metal material which can be used to make downhole tools for oil and gas wells. In order to prepare the material, firstly, according to the requirements of downhole operation technology of oil and gas wells, the overall design idea with magnesium and magnesium alloy as the core was determined, and then the Ni, Ti, Cr, Cu and other metals were determined as auxiliary materials to enhance the alloy strength through electrochemical experiments. After that, these materials are made into degradable metal bars which can be processed by high-temperature and high-pressure die-casting. At last, they are verified by metallographic characterization, tensile impact mechanics experiment, microhardness test, degradation performance and other experiments, which can meet the design and degradation requirements of some downhole tools with low strength requirements. This kind of degradable metal material has the characteristics of light weight, high strength and easy flowback after construction. It is suggested that it should be widely used in downhole tools such as perforating gun, packer, bridge plug and fracturing sliding sleeve.
