Using a high-temperature and high-pressure ultrasonic reactor, the hydrothermal cracking reaction of vacuum residue of Huizhou Refinery. The gas product composition, liquid product composition, reaction coke SEM morphology, and element analysis were investigated to discuss the mechanism of hydrothermal cracking reaction under the effect of ultrasonic wave. The results show that there is no significant difference in the yield of gas products in hydrothermal cracking reaction mechanism of the residue under the effect of ultrasonic wave and the production rate of light oil has been increased slightly while that of coke has been slightly reduced. The angularity of the coke particles is relatively smooth and the pore structure appears, indicating that under the effect of ultrasonic wave, the hydrothermal cracking reaction of residual oil is mainly based on the radical thermal reaction mechanism and the cavatition of ultrasonic wave can promote the residuum to have cracking reaction so that the production rate of light oil has been slightly increased. The mechanical effect of ultrasonic wave causes the raw coke precursor suspended in the residue to oscillate violently, so as to prevent its polymerization, thus having reduced coking, the large increase of Ni in the coke indicates that the catalyst provides a coking center for coking.

Paraffin wax was blended with F-T wax. The effects of the mass fraction of F-T wax on paraffin 46 ^# and 58 ^# were investigated respectively. The results show that the addition of F-T wax can significantly increase the melting point of paraffin, when the mass fraction of F-T wax increases from 0.05% to 30.00%, the melting point of 46 ^# and 58 ^# blended wax drops from 72.4 ℃ to 44.4 ℃, and drops from 88.4 ℃ to 62.4 ℃, respectively. With the increase of the mass fraction of F-T wax, the melting point and penetration of blended wax decrease continuously, that is, the mass fraction of F-T wax is inversely proportional to the drop melting point and penetration. The analysis of the crystalline structure of the blended wax shows that, the content of non-isoparaffins in the blended wax is higher. So its crystal structure is an array of inclined lattice arrangement of the long needlelike wax crystals, and the natural paraffin crystallization is different with others, which composition is more complex.

At present, most of the main agent of conventional clean fracturing fluids are viscoelastic sixteen (or eighteen) alkyltrimethylammonium chloride, which has poor temperature resistance (generally less than 60 ℃). The quaternary ammonium salt type surfactant (JS-VES) based on high carbon chain erucic acid has good temperature resistance.

The highcarbon erucic acidtype clean fracturing fluid system (25 ℃, 170 s ^-1) has an apparent viscosity of 25 mPa•s. It has good shear resistance, and can meet the requirements of suspended sand in the static suspension of sand, with a good breaking capacity (2 mPa•s) and temperature resistance (80 ℃).

The catalyst had the highest methyl orange degradation rate of 95.1% after the reaction for 2 h when the Ag mass fraction was 0.2%. Notably, the degradation rate over the catalyst increased by about 35% comparing with pure strontium titanate powder. Similar to Ag/SrTiO ₃, the degradation rate with Pd mass fraction of 0.2% increased by about 26% comparing with that on pure strontium titanate powder. The mechanism and effect of noble metals on the photocatalytic performance of strontium titanate were briefly discussed.

Based on the conditions above, comparing methane, hydrogen sulfide had larger diffusion range, later dissipation time, and greater risk.

It is difficult to predict the accuracy of the river by using the conventional seismic attributes, due to the complex conditions of the terrigenous clastic basin reservoirs and the rapid change of the rock facies. In this paper, XII7-12 layer in N area of S oilfield is taken as an example. Through the seismic forward analysis, the seismic section reflection characteristics of different types of reservoirs are different, and the seismic attributes of the combined layer can be used as the effective dimension for the main channel prediction in this area. On this basis, using the method of the combination of Gray Relational Analysis and Support Vector Machine, the N zone seismic attribute prediction based on Gray Relational Support Vector Machine is completed. Drilling confirmed that based on Gray Correlation and Support Vector Machine attribute prediction, the drilling coincidence rate is higher. By using the advantage of seismic inversion to predict the boundary of the channel sand, the comprehensive analysis of dynamic and static data of the polymer flooding well group effectively solved the contradiction between the injection and production system of the XII7-12 strata system in the N area of the S oilfield, thus, it further confirms the accuracy of attribute prediction based on GRA-SVM. Comprehensive research shows that this method is suitable for high accuracy of the river prediction and can be used as a better river prediction method under complex geological conditions.

This paper focuses on the fault detection of a class of discrete-time systems with random faults and proposes a fault-dependent approach. Firstly, a mathematical model is constructed to describe the above problems, and the characteristics of fault signals are transformed into matrices containing uncertainties. By constructing a fault detection filter as a residual generator, the fault detection and isolation (FDI) problem is transformed into a H_∞filtering problem. Based on the established model, the  H_∞ performance is analyzed by adopting a fault-dependent method. The parameter-dependent Lyapunov function is selected for processing. On this basis, the existence condition of the fault detection filter is given in the form of linear matrix inequalities. Finally, an example is used to verify the effectiveness and practicability of the theoretical results.

Welding robots have a wide range of applications in manufacturing industries. There are usually many welded joints in the welding task, and a reasonable welding path passes through these welded joints has a significant impact on the welding efficiency. Traditional manual path planning techniques can handle a small number of welded joints effectively, but when the number of welded joints is large, it is difficult to obtain the optimal path. The traditional manual path planning method is also time consuming and inefficient, and cannot guarantee optimality. Genetic algorithmparticle swarm optimization (GA-PSO) is based on the advantages of genetic algorithm (GA) and particle swarm optimization (PSO) to solve the welding robot path planning problem. The simulation results indicate that the algorithm has strong searching ability and practicality and is suitable for welding robot path planning.
