Embodiment 1

[0086] Embodiment 1, the easily soluble metal magnesium alloy material in the present embodiment comprises following composition by weight percentage:

[0087] Al: 10.0%; Li: 0.3%; Ca: 0.3%; Zn: 0.2%; In: 0.03%; Ga: 0.0%; Si: 0.1%;

[0088] Mn: 0.8%; Zr: 0.0%; Fe: 0.016%; Ni: 0.5%; Cu: 0.15%; the balance is Mg and unavoidable impurities.

[0089] combine figure 1 As shown, the manufacturing method of the soluble magnesium alloy material in this embodiment specifically includes the following steps:

[0090] ① Ingredients according to the formula:

[0091] According to the alloy formula of the present invention, the batching is accurately weighed. It uses aluminum-silicon, aluminum-iron, aluminum-nickel, aluminum-copper, aluminum-manganese master alloys and pure aluminum, pure magnesium, pure zinc, pure calcium, pure lithium, and pure indium in the form of furnace materials, which are classified for precise batching.

[0092] ②Smelting, protection and refining:

Embodiment 2～ Embodiment 14

[0106] The easily soluble metal magnesium alloy material in each embodiment comprises following composition by weight percent:

[0107] Table 1 embodiment 2~embodiment 14 weight percentage example composition

[0108]

[0109]

[0110] All the other preparation steps and technical effects are the same as in Example 1.

[0111] The products prepared in the above examples can also meet the requirements for use. Using soluble magnesium alloy materials to replace steel and aluminum products can avoid the high energy consumption and high cost of drilling and grinding secondary processing; replacing low-melting point high-density soluble or soluble alloy products can avoid unsuitable flowback, Technical problems of environmental pollution; replacing organic materials can avoid problems of deformation, easy jamming, and refractory degradation. It is estimated that only soluble balls in each well will bring direct benefits of 30,000 yuan, reduce mining costs by 50,000 yuan, and...

Abstract

The invention discloses an easily-soluble magnesium alloy material which comprises the following elements such as Al, Li, Ca, Zn, In, Ga, Si, Zr, and the like. The invention further discloses a preparation method of the easily-soluble magnesium alloy material. The easily-soluble magnesium alloy material is used for producing products such as a ball sealer, a target, and the like, has technical characteristic of being easy to dissolve or quick to degrade, and can be designed into an oil exploitation underground component or an underground component which is used for performing a temporary function or is temporarily needed. Compared with the prior art, the easily-soluble magnesium alloy material has the advantages as follows: a high operation cost problem for secondary drilling or milling is solved or avoided, and technical and economic effects with low cost and high efficiency are obtained. Meanwhile, the magnesium alloy density is proper, molten slag or corrosion products of the magnesium alloy satisfy flow-back operation technical requirements, and technical effects with multiple advantages of being simple, efficient, environment-friendly, energy-saving, and the like, can be obtained.

Description

technical field [0001] The invention relates to a magnesium alloy material. The magnesium alloy material products (such as soluble balls, darts, etc.) are used in oil wells, oil gas wells and water wells, and can achieve multiple effects of increasing production and income and improving production efficiency. The invention also relates to a preparation method and specific application of the magnesium alloy material, belonging to the technical field of magnesium alloys. Background technique [0002] Petroleum oil fields or oil production wells with low and medium osmotic pressures have low natural production capacity due to low downhole osmotic pressure, and oil oil fields or oil production wells with high osmotic pressures have reduced osmotic pressure and narrow or blocked oil outlet channels in the later stage of oil production. As a result, the efficiency of oil extraction is low, the output is low, and even no oil is produced, forcing oil production companies to adopt va...
