The corrosion inhibition behaviors of 2′‐hydroxy‐acetophenone for AZ91D magnesium alloy in ASTM D1384‐87 corrosive water (model water) were investigated using weight loss and electrochemical measurements. The surface morphologies and composition of films formed on magnesium alloy in solutions with and without 2′‐hydroxy‐acetophenone were examined by scanning electron microscope and Fourier transform infrared spectrum. The results show that inhibition efficiency first increases and then decreases with the increasing 2′‐hydroxy‐acetophenone concentration, its maximum value is at 50 ppm. It is considered that 2′‐hydroxy‐acetophenone anions can chelate with the Mg2+ and form a 2′‐hydroxy‐acetophenone–Mg complex on the magnesium alloy surface, hindering the corrosion development of magnesium alloy.

With the deepening of the exploration of complex hidden oil and gas reservoirs, the spatial characterization of complex reservoir bodies determines the deployment of development wells, and seismic data contains the three-dimensional spatial characteristics of geological bodies and plays an important role in the spatial characterization of reservoirs, among which designing appropriate transfer functions to express the nonlinear relationship between seismic data and reservoirs is the key to solving the problem. At present, the transfer functions are concentrated in low-dimensional functions or high-dimensional functions of fixed mathematical models, which cannot accurately depict the nonlinear mapping relationship between seismic data and complex reservoirs, resulting in low spatial description accuracy of reservoirs. In this paper, the hybrid nonlinear transfer function is established to convert the seismic volume fusion attribute into the light blockers attribute, and then the emission model and light projection method are used to render the reservoir volume, so as to achieve the purpose of illuminating the reservoir and shielding the non-reservoir, and improve the depiction accuracy of the three-dimensional spatial characteristics of the reservoir.
