Abstract: At present, the production of natural gas is often accompanied by problems such as liquid accumulation at the bottom of the well, wellbore corrosion, and hydrate plugging. The traditional solution to these problems is to use a single chemical agent. Usually, foaming agents, corrosion inhibitors and hydrate anti-agglomerants are injected into the wells to mitigate the liquid loading, corrosion and blockage caused by gas hydrate, respectively. However, the issues associated with liquid loading, corrosion and blocakeges by hydrate often occurs at the same time, there may be compatibility issues among the foaming agents, corrosion inhibitors and hydrate anti-agglomerants. If multi-functional integrated agents are developed, those three problems mentioned above can simultaneously be solved. However, there are few reports regarding the multi-functional integrated agents that can simultaneously solve the above three problems. This article combines the action mechanism and development status of foaming agents for gas well deliquification, corrosion inhibitors and hydrate anti-agglomerants to propose a multi-functional integrated agent that simultaneously has liquid unloading, corrosion inhibition and hydrate anti-agglomeration, providing a new idea to efficiently promote the natural gas production.Abstract: At present, the production of natural gas is often accompanied by problems such as liquid accumulation at the bottom of the well, wellbore corrosion, and hydrate plugging.

Abstract: The shortage of natural aggregates in the construction industry has prompted the search for alternative materials that can replace or partially replace traditional aggregates in concrete. Shellfish, which are widely available and have certain strength properties, are one of the potential candidates for this purpose. However, the use of shells as aggregates also brings some challenges, such as the reduction of compressive strength and the increase of dry shrinkage of concrete. To overcome these drawbacks, fibers are added to shell aggregate concrete to enhance its mechanical performance and durability. This paper investigates the feasibility and effectiveness of using different types of fibers, such as reed fiber, nanofiber, and coir, in shell aggregate concrete, and the influence of shell work and the influence on the hydration reaction of concrete is comprehensively analyzed on the working performance of shell aggregate concrete. The experimental results show that the incorporation of fibers can improve the workability, compressive strength, flexural strength, splitting tensile strength, and shrinkage of shell aggregate concrete. The optimal fiber content and aspect ratio are also determined for each type of fiber. The paper concludes that shell aggregate fiber concrete is a viable and sustainable material for structural applications, and provides some recommendations for its design and use.Abstract: The shortage of natural aggregates in the construction industry has prompted the search for alternative materials that can replace or partially replace traditional aggregates in concrete.
