Influence of Supercritical CO Fracturing Fluid on the Permeability of Shale Reservoir and Mechanism Analysis.

Reduction of the reservoir permeability during supercritical CO fracturing caused significant reservoir damage, which directly affects the crude oil recovery rate. This investigation explored a novel thickener for supercritical CO fracturing fluid, this CO thickener not only effectively improves the viscosity and rheological properties of CO fracturing fluid but also contributes to reduce reservoir damage and improve permeability. The research results indicated that the synthesized CO thickener (3 wt %) can increase the apparent viscosity of supercritical CO fracturing fluid to 7 mPa·s, and a 9% matrix permeability damage rate and a 0.

Brain-Imaging Mechanisms on Female Abdominal Obesity Treated by "Shu-Mu" Acupoint Catgut Embedding and Compatibility Relation: Study Protocol for a 12-Week Randomized Controlled Trial.

Background: Acupoint catgut embedding (ACE) has been proven to be effective and safe in the treatment of obesity, but few studies have been conducted involving its central mechanisms. Our previous study has demonstrated the effectiveness of Shu-Mu ACE in the treatment of abdominal obesity (AO). However, the neurological mechanism of Shu-Mu ACE for weight loss has not yet been elucidated.

Efficacy of contralateral acupuncture in women with migraine without aura: protocol for a randomised controlled trial.

Introduction: Migraine is a common neurological disorder with a higher prevalence occurring in women. Migraine without aura (MwoA) is the most common type of migraine. In recent years, the safety and effectiveness of acupuncture for migraines have been internationally recognised.
