Hydraulic fracturing is an indispensable technology in developing tight oil and gas
resources. However, the development of tight oil and gas is not consistently satisfactory …

Hydraulic fracturing has been widely used in tight reservoir to generate fractures to improve
the conductivity and productivity. However, due to combined effects of volcanism, tectonic …

Deep shale gas reservoirs are characterized by high in-situ stresses, a high horizontal-
stress difference (12 MPa), development of bedding seams and natural fractures, and …

埋深大于3 500 m 的深层页岩储层具有高水平主应力差, 发育层理裂缝, 低脆性指数等特点,
在压裂改造时难以形成复杂裂缝. 为了充分认识其水力裂缝扩展规律, 采用三维离散格子方法对 …

Geothermal energy has been widely proposed as a potential renewable energy to replace
traditional fossil fuel energy. Hot dry rock (HDR) reservoirs were the main geothermal …

Hydraulic fracturing has been widely applied to stimulate the natural gas and oil production
from unconventional reservoirs. To optimize the design of hydraulic fracturing in this …

Stimulation technology is the key to efficient development of deep low-permeability
carbonate reservoirs. For such reservoirs, where the porosity and permeability are low, or …

Abstract Liquid nitrogen (LN 2) ultra-low temperature fracturing technology has broad
application prospects in the storage and transformation of geothermal wells. Therefore, it is …

Acid fracturing is the most effective stimulation method to obtain a high production of
carbonate formation which is an important oil and gas resource for China to meet the …

The shale oil reservoirs of the Lucaogou Formation in the Jimsar Sag developed a large
number of natural fractures and thin interlayers. The expansion of hydraulic fractures is full of …
