METHODS OF ADJUSTING THE RATE OF GALVANIC CORROSION OF A WELLBORE ISOLATION DEVICE. |
摘要 |
A wellbore isolation device comprises a first material and pieces of a second material, wherein the first material: is a metal or a metal alloy; forms a matrix of the portion of the wellbore isolation device; and partially or wholly dissolves when an electrically conductive path exists between the first material and the second material and at least a portion of the first and second materials are in contact with the electrolyte, wherein the pieces of the second material: are a metal or metal alloy; and are embedded within the matrix of the first material; wherein the first material and the second material form a galvanic couple and wherein the first material is the anode and the second material is the cathode of the couple. The isolation device can also include a bonding agent for bonding the pieces of the second material into the matrix of the first material. |
