The mud pump is an important power component of petroleum drilling. The crankshaft, as an important part of the mud pump, requires optimization of the crankshaft structure in order to improve the efficiency of the mud pump. First analyze the workload of the crankshaft, and obtain the stress point and load size of the crankshaft work. Through the finite element simulation, the corner of the crank rotation and the maximum deformation of the crankshaft and the maximum stress is obtained. Combining the production process to open the hole, use the non -linear regression model to establish the relationship between the crankshaft structure optimization target and the opening diameter of the opening, and use multiple target optimization methods to find the optimal variable. The maximum stress, maximum variable volume, and the total mass optimization effect of the crankshaft is obvious, reducing product costs.

In the manufacture of solar cells, the resistivity of silicon wafers has a crucial impact on their performance. This study investigated the effects of different resistivities on p-TOPCon solar cells. The results indicate that lower resistivity wafers have a higher implied open-circuit voltage (iVoc) value, but higher carrier mobility due to the low resistivity leads to an increase in saturation current density (J0). Conversely, solar cells made on higher resistivity silicon wafers have a lower carrier mobility, leading to slower electron-hole recombination and lower bulk recombination, resulting in the advantage of lower saturation current density and higher minority carrier lifetime. At the same time, simulation shows that as the resistivity increases, the Voc and efficiency increase. However, cost considerations need to be taken into account as higher resistivity silicon wafers are more expensive. Therefore, resistivity between 2 - 3 Ω·cm2 is considered the preferred substrate for solar cells as it offers a better balance between cost and achieving high cell efficiency.

Distributed PV (photovoltaic generation) is a distributed PV energy system that uses photovoltaic modules to convert solar energy into electric energy. In this paper, a two-level and two-stage scheduling optimization model and its solution algorithm under distributed PV energy system are constructed. Firstly, based on load forecasting and intermittent energy output forecasting data, this paper establishes a two-stage scheduling optimization model of distributed energy system under active distribution network. Then, the improved PSO (Particle swarm optimization) algorithm is introduced to optimize the scheduling model. Finally, the proposed model is validated by simulation results. The simulation results show that using the double-layer and two-stage scheduling strategy proposed in this paper to optimize the distributed PV energy system can not only optimize the power consumption structure, but also play the role of peak shaving and valley filling, and the state of charge of the battery has been higher than 50%, which can effectively increase its service life. Under the double-level and two-stage scheduling strategy, users get the most benefits, and the revenue growth rate is 20.07%.

Energy transformation is a systematic change that affects the national economy and society. It is not only the change of internal supply and demand structure of energy, but also closely related to economic industry and environment. In order to achieve the goal of carbon neutrality and "double carbon" in peak carbon dioxide emissions, it is very important to do a good job in energy transformation. This paper evaluates the impact of energy transformation path on the economic and industrial benefits and environmental health of Guangdong-Hong Kong-Macao Greater Bay Area city, and concludes that energy transformation has a good impact on the economic and environmental health of the country and society. Therefore, cities in Guangdong-Hong Kong-Macao Greater Bay Area should do a good job in carbon emission reduction, steadily promote energy transformation in the new era, and realize green energy transformation and coordinated development of energy, economy and environment.

Oil shale is an important part of unconventional resources, which is considered as an important replacement for traditional oil resources. At present, the underground in-situ conversion method of oil shale is mainly aimed at shallow reservoirs, and it is difficult to apply to in-situ exploitation of oil shale with a depth of more than 1000m. In view of the portability, fracturing and extraction characteristics of high-pressure sub/supercritical water, it has become the research direction of in-situ mining of deep oil shale. The evolution of pore structure of oil shale is the basis for exploring the production mechanism of sub/supercritical water pyrolysis of oil and gas, which has important theoretical and scientific significance for improving the development and utilization of in-situ injection of sub/supercritical water in deep oil shale. Therefore, in this paper, the oil shale of Jijuntun Formation of Paleogene in Fushun Basin is taken as the research object. The pyrolysis experiments of oil shale in three ways, namely, water-free (electric heating), subcritical water and supercritical water, are carried out by means of high temperature and high-pressure source rock pyrolysis simulation device. The evolution characteristics of nano-pore structure under different pyrolysis methods are studied by XRD and low temperature nitrogen adsorption technology. The results show that, compared with anhydrous pyrolysis at the same temperature, the pore size of 3-30 nm of oil shale increases significantly after sub/supercritical water pyrolysis. The phenomenon of kaolinite illite fossilization increases, and the overall weak acidic environment is more conducive to the transformation of illite into Illite and montmorillonite mixed layer minerals, easier to increase the pore space in oil shale, and conducive to the migration and accumulation of produced oil and gas.

On the basis of understanding the regional tectonics characteristics and stratigraphic sedimentary characteristics of the study area, the sequence stratigraphic framework within the region is gradually studied by applying the principle of high-resolution sequence stratigraphy, and G4 oil formation is divided into three sets of sand formations, namely, G4 upper, G4 middle, and G4 lower sand formations, and divided into small layers in detail. Through comprehensive analysis of lithofacies, logging facies, and seismic facies, the sedimentary facies of the G4 oil formation are comprehensively analyzed. The main sedimentary facies type of the G4 oil formation is the delta front facies belt, and the most important sedimentary microfacies in the delta front facies belt are underwater distributary channel sedimentary microfacies. Using seismic sedimentology methods, make stratigraphic slices of each sub layer of the G4 oil formation, and use the rapid browsing method of stratigraphic slices to trace river sand in detail.

This paper presents an experimental study of the flame trajectory line length for a buoyancy-controlled dual linear jet flame at different inclined angles (0° ~ 90°). Two nozzles of the same size (80mm*1mm) were used for the experiments, propane was used as the fuel, the range of fuel exit velocity was 0.63 ~ 4.17m/s, the range of burner spacing was 0-0.6m, and a digital camera was used to record the flame morphology. In this paper, a critical spacing Dc is introduced to indicate the change of flame height, and a prediction model of Dc and fuel exit velocity Uf is established to divide the flame trajectory length with spacing into two stages, namely: when SDc, the flame trajectory length does not change significantly with the increase of spacing, and finally approaches to a single free flame trajectory length. When S>Dc, the flame trajectory length did not change significantly with the increase of burner spacing, and finally approached to a single free flame trajectory length, so the flame trajectory length showed a complex non-monotonic evolution. Based on the analysis of the air entrainment, two global models are developed to predict the trajectory lengths of the buoyancy-controlled dual-jet flame system in two states with different initial inclined angles. the model was applied to correlate all the data in this study as well as the data in previous studies.
