“…According to other studies [2,6,7], the mechanical properties of the dissolvable fracturing balls are generally as follows: the values of UCS, elongation and HV are 360 MPa, 20% and 60 HV, respectively. What's more, the optimization of the mechanical properties of WE34-1Ni by electro-magnetic induction is obtained at 4.10 kW power with the semi-solid temperatures 625°C.…”

“…In general, the mechanical strength of the dissolvable fracturing balls should be enough to ensure the regular operation in the whole fracturing process. And compression strength (UCS), elongation and microhardness (HV) for the dissolvable fracturing balls should exceed 360 MPa, 20% and 60 HV, respectively [2,6,7]. Moreover, WE series alloys balancing magnesium (Mg), yttrium (Y), neodymium (Nd), and zirconium (Zr) have excellent mechanical properties [8][9][10][11].…”

The semi-solid billets of Mg-2.4Y-4Nd-0.5Zr-1Ni (WE34-1Ni) alloys are fabricated by electromagnetic induction heating semi-solid treatment at 2.05 kW and 4.10 kW from 580°C to 625°C. In this work, the microstructure evolution and mechanical properties of WE34-1Ni alloys are investigated, and the results reveal that with increasing semi-solid temperatures, the average grain size of the solid globules and liquid fraction at the grain boundary gradually increase while the shape factor fluctuates slightly. Compared with 2.05 kW power, the semi-solid billet with 4.10 kW power at 625°C has more fine homogeneous grains, the lower average size of the solid globules, more liquid fraction. The semi-solid billet with 4.10 kW at 625°C obtains ideal semi-solid spheroid structure with the solid grains surrounded by a small amount of liquid pools and the best mechanical properties of the semisolid process parameters. Besides, the elongation as-extruded of WE34-1Ni alloys increased from 21.4±0.7% to 33.2±0.3% at 4.10 kW power and 625°C via electro-magnetic induction heating semi-solid treatment.

The dissolvable bridge plug is one of the most important tools for multi-stage hydraulic fracturing in the field of oil/gas development. The plug provides zonal isolation to realize staged stimulation and, after fracturing, the plug is fully dissolved in produced liquids. A bionic surface was introduced to improve the performance of the plug. Surface dimples in the micron dimension were prepared on the dissolvable materials of the plug. The experimental results showed that the surface dimples changed the hydrophilic and hydrophobic properties of the dissolvable materials. The dissolution rate has a great relation with the parameters of the dimples and can be controlled by choosing the dimples’ parameters to some degree.

“…In recent years, the application of degradable Mg alloys as hydraulic fracturing tools, such as fracturing balls, ball seats, and bridge plugs, has gained much attention. [1][2][3] Hydraulic fracturing technique is considered the most economically efficient means for the development of unconventional reservoirs. [4,5] Figure 1 shows a schematic of the horizontal staged fracturing system.…”

“…The application of degradable materials in fracturing tools avoids the milling or drilling operation resulted from the traditional undegradable fracturing tools (such as steel and aluminum alloys), making the oil and gas production more economic and highly efficient. [8,9] To ensure the fracturing tools can degrade rapidly in the limited time after fracturing operations, the degradable materials need to have rapid degradation rate. Meanwhile, as fracturing tools, the materials should have sufficient strength to adapt the high-pressure service condition.…”

Degradable materials with low density exhibit unique applications in the petroleum equipment field. Herein, hollow glass microspheres (HGM)‐reinforced Mg alloy degradable composites are fabricated. The microstructure and degradation behavior of the composites are investigated using scanning electron microscopy, immersion tests, and electrochemical measurements. Then the influence mechanisms of the HGM on the degradation property of composites are further revealed. The results show that the addition of the HGM significantly reduces the density of the composites. Different degrees of chemical reaction between the Mg alloy melt and HGM wall happen during the fabrication of the composites, resulting in the formation of MgO and Mg2Si. From the corrosive morphologies of the composites, Mg2Si phase can serve as a microgalvanic cathode consequently inducing more galvanic corrosion. The interface between HGM and matrix alloy can serve as the initiation site for pitting corrosion and increase the exposed area of the matrix in the aggressive medium. The electrochemical measurements prove that the HGM can act a part in facilitating the exfoliation of degradation products. Consequently, the HGM greatly increases the degradation rate of the composites in the KCl solution. The current study provides a new insight for developing lightweight Mg‐based composites with quickly degradable performance.
