Heat insulated tubing and casing
Overview
According to relevant data, geological reserve of heavy oil around the globe is 10 times than crude oil. But API standard has not the heavy oil casing for thermal recovery oil, and there is no mill in the domestic and abroad to develop the casing for heavy oil exploration. So the oil field can only use the common API casing whose damage rate is higher. The demand for the process of the heavy oil exploration is higher. In this case, our company has developed a series of heat insulated casing used for oil exploration of thermal recovery wells.
Features of the products
This series of high-level grade casing for heavy oil exploration has been developed by using material with specific elements on the bases of broad inspection and study of the mechanical characteristics of casing in the process of heavy oil exploration and failure types of the casing. The material is of good thermal stability and the strength property still remains stable at the temperature of
350℃. It has better seal property and high thermal durability.
