Analysis of the Application of Horizontal Well Technology in the Development of Offshore Natural Gas Hydrate
Horizontal well development of natural gas hydrate (NGH) can greatly improve gas production and make it cost-effective, which is one of the key technologies for the efficient development of NGH in the future. World widely, there is only limited experience in drilling horizontal wells into gas hydrate sediments, which lacks certain reference. In this paper, the practice of drilling horizontal wells into gas hydrate sediments, were analyzed the challenges. The challenges encountered when drilling horizontal wells into hydrate sediments were also analyzed. At least, the application of horizontal wells and complex well structure, which based on horizontal wells are analyzed. The advantages and disadvantages of several novel well structure are compared. This paper will contribute to the development of natural gas hydrate of our country.
期刊介绍:
Chemistry and Technology of Fuels and Oils publishes reports on improvements in the processing of petroleum and natural gas and cracking and refining techniques for the production of high-quality fuels, oils, greases, specialty fluids, additives and synthetics. The journal includes timely articles on the demulsification, desalting, and desulfurizing of crude oil; new flow plans for refineries; platforming, isomerization, catalytic reforming, and alkylation processes for obtaining aromatic hydrocarbons and high-octane gasoline; methods of producing ethylene, acetylene, benzene, acids, alcohols, esters, and other compounds from petroleum, as well as hydrogen from natural gas and liquid products.
