Fluid accumulation in gas wells lead to a sudden drop production and is problem. This paper proposes prediction system for water-producing using edge intelligence. The method characterized by use of intelligence realize automatic collection well data, effusion analysis, data backup, upload, dynamic monitoring, other functions. Pearson correlation coefficient was employed analyze the relevant parameters liquid wells. A collaborative discrimination approach utilizing convolutional neural...
The study of hydrate phase equilibrium is crucial for ensuring the safety natural gas pipeline transportation and process recovery. While scientists typically focus on chemical potential hydrates, role solubility in remains unclear, this fills gap. This work investigated at point through model calculations. Additionally, a new established based relationship between solubility. Firstly, gas-liquid theory showed higher prediction accuracy comparison to PR equation Duan was then used calculate...
The petroleum industry is increasingly focused on high-temperature, high-pressure oil reservoirs, and they face challenge in generating sufficient surface construction pressure without exceeding the capabilities of equipment. To address this issue, now predominantly relies weighted fracturing fluid. However, fluid unreasonably expensive difficult to break up. Thus, researchers are urged develop a low-cost, that can be easily fractured. polymer thickener GTA, with poly-hydroxy groups capable...
This article mainly introduces the method of TOPSIS and describes in much detail application seeking optimum blended coal by confirming weight index with entropy. A combustion power plant issue as an example, is selected under condition that four aims kinds coals. The can combine qualitative analysis quantitative effectively, synthesize evaluating information each adequately, which provides a good way for optimization
Abstract Owing to factors such as production system change, pump shutdown and workover, there was sudden drop in formation fluid velocity of coalbed methane well Hancheng block, resulting water blocking damage, the gas plunged after reopened. In order remove damage reservoir, this paper integrated extensive survey, initially selected two nonionic surfactants (B4-B5) three anionic (B1-B3) experimental subjects. The results showed that mixed effect B3 B5 is best. further improve formula...
Abstract Gas wells need to face the problem of gas well outflow during production, and main way deal with fluid accumulation is calculate critical liquid carrying velocity other factors by using prediction model excess accumulation. When results hydrops are biased, will be generated at bottom wellbore, resulting in a decrease productivity. Aiming that drag coefficient wellbore droplet movement changes greatly process natural which leads error effusion prediction, commonly used models common...
Contraposing the indeterminable problems such as fuzziness and diversification which influenced slagging of coal ash, grey cluster decision was applied in evaluating properties power generation paper, combined with fuzzy TOPSIS method.

Research of the application on Mathematical Economic Model in Terms Gas Distribution and Reconstruction Field Coal Mine Stope The research is divided into 2 sections, first section to analyze mathematical economic model coal mine stope gas distribution; second mathematic reconstruction distribution field. From perspective economy, when there are a lot data samples participating field reconstruction, based neutral network algorithm slightly superior space information statistical approach....
Research on estimated ultimate recovery (EUR) is crucial before shale gas reservoir development and production. However, there still a lack of systematic summary the influencing factors well EUR, have not been combined with flow stage. Moreover, are gaps in research influence various EUR. To fully understand EUR after fracturing, find out weight value each factor's this paper comprehensively reviews fracturing recent years from three aspects geology, engineering, The production wells divided...
Abstract The successful use of waterfrac to tight gas reservoirs was presented by M.J. Mayerhofer et al[1–3]. However, its application stimulate permeable oil is not reported our knowledge scope. This paper presents the a shallow reservoir with low permeability, M Laojunmiao field (the oldest China). average permeability 24.2 mD. different scenario from that because higher fracture conductivity required in order ensure fracture's flow capability. more than forty-year history, development,...
