Based on the cracked chevron notched Brazilian disc method, the I-type fracture toughness
of Longmaxi Formation shale is measured and the influence of different factors on the …

As the drilling depth of shale's oil and gas wells increases worldwide, the problem of
borehole collapse and instability becomes increasingly serious. Due to the high content of …

During the drilling process, the issue of drilling fluid loss can lead to changes in the
mechanical properties of the formation, thereby altering the stress environment of nearby …

Clay shale is frequently encountered in drilling. With strong hydration capacity, when clay
shale contacts with drilling fluid, rock structural and mechanical property will be affected …

China is rich in shale gas resources, however, wellbores in shale gas reservoirs are
frequently unstable. This has a serious impact on the shale gas drilling cycle. Polyamine, a …

The problem of wellbore stability in hard brittle shale formations is an important research
topic in the exploration and development of shale gas. To solve this problem, the …

In this paper, the ionic liquids Met-1, Met-2, Asp-1 and Asp-2 were prepared by acid-base
neutralization reactions with different molar ratios of amino acids (methionine and aspartic …

The acoustic response characteristics of shales were investigated by the acoustic
transmission experiment, which is the basis of solving geological and engineering problems …
