Characteristics and comparison of karst reservoirs of lower Paleozoic in Nanpu Sag and outcrops

The carbonate buried hill in Nanpu Sag is an important deep oil and gas exploration field with deep burial and old age., complex tectonic movements and the characteristics of multi-stage karstification. Based on the drilling, core, logging and seismic data of outcrops around Tangshan and Nanpu Sag, the characteristics of karst reservoirs in outcrops and sag were compared and analyzed. The results show that: outcrops around Tangshan and Nanpu sag The Lower Paleozoic structural-karst background in the sag is basically consistent and has good contrast. The typical fault-controlled karst reserv

Numerical analysis of influence of flat plate diffuser parameters on performances of hot water storage tank

The thermocline hot water storage tank is the key equipment of large-scale solar central heating system, and the water distributor serves as the thermocline The layered hot water storage tank is an important component, and its structural parameters have an important impact on the thickness of the inclined temperature layer and the exergy efficiency in the tank. The number of openings, opening diameter, radius of the water distributor, and heat storage of the disc-type water distributor The influence of structural parameters such as the height-to-diameter ratio of the water tank on the heat

Regulation of visible-near infrared dual-band spectral radiative characteristics on biomimetic radiative cooling film

Radiant refrigeration is a zero-energy cooling technology with broad application prospects. However, most of the existing radiant refrigeration technologies Visible light transmission factors are not considered and cannot be applied to scenarios such as lighting buildings and photovoltaic cells. Based on the principle of spectral radiation control of beetle cutin, a method of using the refractive index difference of multi-layer films to achieve spectral radiation control is proposed to screen low-cost ITO and SiO2 , PDMS, etc. were used as base materials to construct an efficient and low-co

Molecular dynamics investigation of dissolution of carbon dioxide in methane

Pressurized liquefied natural gas (PLNG) technology can significantly improve the solubility of CO2 in LNG, but its microscopic process of dissolution and The mechanism has not yet been revealed. To this end, CO2 and methane were used as research objects, and molecular dynamics simulation methods were used to systematically study the changing rules and dissolution mechanisms of CO2 solubility in liquid methane at different temperatures. The results show that: the solubility of CO2 in liquid methane changes with It increases as the temperature rises, and the trend of increasing as the temper

Numerical simulation optimization of injection parameters by viscosity reducer flooding in Gaoqing heavy oil reservoir

The numerical simulation method was used to evaluate the application effect of viscosity reducer flooding in Gaoqing oil reservoir. Based on the indoor viscosity reducer evaluation test results, a numerical simulation model of viscosity reducer flooding was established, and the viscosity reducer injection parameters were determined based on the oil increase per ton of agent. Optimization. The results show that when the viscosity reducer mass concentration is 3000 mg/L, the injection rate is 200 m3/d, and a total of 0.2 VP (pore volume) of viscosity reducer is injected, the oil increase per
