SELECTION OF DRILLING FLUID PROPERTIES WHEN DRILLING GAS HYDRATE DEPOSITS

Аннотация

The dissociation of gas hydrates during drilling is a serious problem. In practice, when drilling exploration and production wells, drillers often encounter gas shows that occur due to the decomposition of gas hydrates. This paper describes the reasons for the dissociation of gas hydrates during the drilling of hydrate-containing formations and forms the requirements for the drilling fluid to prevent potential complications.
