The variation of coal rank in the Anyang-Hebi (Anhe) coalfield has phenomenon anti-Hilt law, which makes distinctive for coalbed methane exploration research. adsorption characteristics and influencing factors medium-to-high samples Shanxi Formation this were analyzed. results indicate that Langmuir volume ( V L ) coals shallow western part Anhe is generally higher than deep eastern part. macerals are dominant influence capacity law area. capacity, represented by , first increases then...
Abstract To reduce the dependence of oil-based drilling fluids for extended reach well drilling, a newly developed water-based fluid system has been used to drill wells in Liuhua oilfield located east South China Sea. Based on numerous experiments, formulations this various sections were determined, and several key characteristics, such as lubricity, inhibition, rheological properties, evaluated. Using 11-1-21 (A4) ERW3 an example, field applications are elaborated article. Laboratory...
Scaling text-to-speech (TTS) with autoregressive language model (LM) to large-scale datasets by quantizing waveform into discrete speech tokens is making great progress capture the diversity and expressiveness in human speech, but reconstruction quality from token far satisfaction depending on compressed compression ratio. Generative diffusion models trained score-matching loss continuous normalized flow flow-matching have become prominent generation of images as well speech. LM based TTS...
Based on the complicated geological conditions of coal seam in Xuandong Coal Mine, such as deep burial depth, high gas content, magmatic rock intrusion and so on, distribution regularities rock, structures were analyzed studied. Combining with practical situation dynamic disaster phenomenon during mining, dangerous zones outburst predicted regional divided. The research results would have certain significance guide to prevention reduction.
In this paper, we describe a workflow that integrates geomechanical, fluid-flow and seismic modelling can be used to predict the stress distribution evolution as well various attributes before during production. Poroelastoplastic constitutive model is incorporate matrix failure simulation, allowing strain hardening weakening develop within model. This especially important for reservoir path asymmetry. The material also enables prediction of when where occurs in model, us likely microseismic...
Abstract Pressure and the flow distribution are not uniform due to pressure drawdown in a horizontal wellbore, thus reducing effectiveness of toe well increasing tendency for water gas coning at heel. Completions have been proposed combat this effect using stinger that extends from heel into section. A comprehensive three-dimensional, anisotropic reservoir/wellbore coupling model based on equivalent wellbore radius principle potential superposition was developed. The is capable handling...
The criteria of traditional block matching motion estimation algorithm is based on the gray value offset between macro block, which was sensitive to noise and treatment under uneven illumination environment.For above problem, paper proposed that using canny extracted edge profile current frame, then calculate feature points distribution histogram estimated, finally, distance two frames as for all frames.The experiment showed that, accuracy improved high, it has small difference target...
The signal-to-noise ratio of long-distance relay free communication systems and quantum secure is very low, making it difficult to achieve high-performance error correction. In order effective correction, longer code words or higher iterations are generally chosen the highest correction efficiency as possible. However, this will greatly increase complexity process reduce real-time performance. To solve problem, we propose a algorithm based on deep neural network. case low ratio, performance...
