Problems solved by technology

The fracturing ball used to temporarily plug the sleeve during the fracturing process is generally made of nylon. The fracturing ball will be deformed during use, and it is easy to get stuck in the sliding sleeve, resulting in interruption of the operation; in addition, the existing fracturing Because the balls are insoluble in the fracturing fluid, flowback operations are usually required, reducing production efficiency

Abstract

The invention discloses a high-pressure-resistant instant-solubility fracture ball and a preparation method thereof. The high-pressure-resistant instant-solubility fracture ball is prepared from the following components, by weight, 70-90 parts of Mg, 15-20 parts of an Al-Ga alloy, 15-20 parts of an enhanced Al alloy, 5-10 parts of Ni, 10-20 parts of Ag, 0.1-0.5 part of micro element In, 0.1-0.5 part of micro element Sn and 0.1-0.5 part of micro element Bi. The preparation method includes the following preparation steps that (a), Ag and the micro elements are smelted under the vacuum condition; (b), Mg, the Al-Ga alloy, Ni and the alloy prepared in the step (a) are smelted together; and (c), smelting is performed together with the enhanced Al alloy, and after smelting is completed, the smelted mixture is injected into a mold, and cleaning is performed. The high-pressure-resistant instant-solubility fracture ball and the preparation method thereof have the beneficial effects that the supporting strength requirement during well fracturing operation can be met, fast solubility can be achieved, and reliability is high.

Description

technical field [0001] The invention relates to a high-pressure-resistant instant fracturing ball and a preparation method thereof. Background technique [0002] With the continuous deepening of oilfield exploration and development and the improvement of production technology, oil and gas reservoir fracturing technology has been more and more applied, and has become an important measure for low-permeability oil and gas reservoir reconstruction and production increase. The fracturing ball used to temporarily plug the sleeve during the fracturing process is generally made of nylon. The fracturing ball will be deformed during use, and it is easy to get stuck in the sliding sleeve, resulting in interruption of the operation; in addition, the existing fracturing Since the balls are insoluble in the fracturing fluid, flowback operations are usually required, reducing production efficiency. Contents of the invention [0003] Purpose of the invention: The purpose of the present i...
