During the middle and later stages of condensate gas field development, the flow rate and pressure of the light hydrocarbon recovery system gradually decrease, and there is a certain deviation between the design parameters and the actual operation parameters of the equipment, resulting in a...

With the continued downturn in global crude oil prices, the natural gas market shows a rapid growth trend. The coordination of natural gas trade is becoming more and more important, and many organizations have put forward natural gas energy metering the schemes. Nowadays, the energy metering...

The accurate forecasting of short-term load for urban gas is the premise of gas supply sales, pipe network planning, and energy optimization scheduling. This paper adopts a hybrid model that integrates the fruit fly optimization algorithm (FFOA), simulated annealing algorithm (SA), cross factor...

In the environment where the traditional energy industry is declining and the new energy industry is developing rapidly, we collected the data from 98 new energy companies listed in China’s Shanghai and Shenzhen stock markets from 2012 to 2016 to conduct an empirical study to understand the...

Triboelectric nanogenerators (TENGs) have been investigated as a promising methodology to harvest mechanical energy into electricity. The matching impedance and the transient property of TENGs are important for their practical application. In this work, we proposed novel paper-based methodology...

Because the influence of shear on the rheology of waxy crude oil must be considered according to the composition and structure of the waxy crude oil transported via pipeline when a new pipeline is constructed, the risks associated with changes in the waxy crude oil composition during the...
