In the natural gas pipelines, the so-called black powder is formed. It can take many forms, including wet tarred substance or fine dry powder. Black powder occurs in both newer and older natural gas pipelines. This can disrupt the distribution of…
Abstract: The possibilities of using special rheological properties of polymers in the petrochemical industry, in particular, at the stage of oil production in the modification of drilling fluids and oil displacement, the transportation of oil in…
The biomaterials have gained the attention for utilization as sustainable alternatives for petroleum-derived products due to the rapid depletion of petroleum resources and environmental issues. Chitosan is an economical, renewable and abundant…
This work aims to explore the overflow characteristics of a vertical H2S-containing natural gas well. A two-phase flow model for H2S-containing natural gas well combining with a transient temperature prediction model was established to simulate the…
As a new unconventional clean energy, natural gas hydrate has attracted attention in recent years. In marine natural gas hydrate reservoir drilling, hydrate cuttings will return upward in annulus. In this process, hydrate cuttings will decompose…
The deepwater drilling and cementing techniques achieved significant development in recent years. However, the engineering response mechanism of natural gas hydrate sediment (NGHS) during drilling and cementing process is far from clear, which…
For rational design of drilling process parameters and guarantee of safe drilling, law of carrying cuttings in horizontal well drilling of marine natural gas hydrate should be intense research to effectively reduce the friction of drilling tools and…
The natural gas hydrate resources in the South China Sea alone are about 85 trillion cubic meters. In the drilling process of marine gas hydrate, the natural gas hydrate will decompose and produce gas, as the rising of temperature and dropping of the…
The drilling fluid invasion into hydrate-bearing sediments (HBS) would trigger geological risks. However, invasion mechanisms and formation responses during drilling the gas hydrate reservoirs, especially the fluid-loss characteristics and control…
Horizontal wells can significantly improve the gas production and are expected to be an efficient exploitation method for the industrialization of natural gas hydrates (NGHs) in the future. However, the near-wellbore hydrate is highly prone to…
