The Baiyanghe block in Fukang, Xinjiang, China, is rich coalbed methane (CBM) resources, and several pilot experimental wells have yielded high production. Due to the dip angle (35–55°) of coal seam this area, lack understanding geological characteristics, physical properties coal, gas–water migration law lead immature development techniques poor overall benefits. We first conducted desorption ...

The productivity of low-permeability reservoirs is affected by multiple factors. After the development water injection pressure drive, it will also be factors such as construction, resulting in large differences different oil wells. According to reservoir engineering knowledge, affecting drive are preliminarily determined. conceptual model low permeability established numerical simulation metho...

The existence of two independent components of long-term memory has been demonstrated by the authors. The evidence has been derived from the authors' findings related to the optimum spacing of repetitions in paired-associate learning. The two components are sufficient to explain the optimum spacing of repetitions as well as the spacing effect. Although the molecular counterparts of the two comp...

Aquifer thermal energy storage (ATES) is a time-shifting technology where waste heat stored in an aquifer for weeks or months until it may be used at the surface. It can reduce carbon emissions and HVAC costs. Low-temperature (<25 °C) (LT-ATES) already widely-deployed central northern Europe, there renewed interest high-temperature (>50 (HT-ATES). However, unclear if LT-ATES guidelines well spa...

Based on the brain storm optimization algorithm, this paper proposed a new method to optimize beam collection efficiency of linear antenna array. In process optimization, constraints such as aperture size and minimum spacing are considered. paper, with different apertures, angles, array numbers studied. A series representative data simulation results given superiority brainstorming algorithm is...
