Description
Technical field
The present invention relates to the spiral lifting technology of lifting high temperature fluid, specifically a kind of spiral lifting equipment and forming method of being used for the heavy crude heat extraction technology made from metal material.
Background technology
According to statistics, the reserves of viscous crude, special viscous crude and natural asphalt are about 1000 * 10 in the world petroleum resource
8T.There are Canada, Venezuela, the U.S., China etc. in the country that the viscous crude resource is relatively abundant, and its heavy oil and sand asphalt resource are about 4000 * 10
8T-6000 * 10
8T, the viscous crude annual production is up to 1.27 * 10
8More than the t.In so large-scale development process, be subjected to the large impact of its development difficulty, countries in the world are successively dropped into a large amount of scientific research technical forces and are carried out correlative study, so far, thickened oil recovery can be divided into thermal recovery and cold 2 classes of adopting, wherein take heating exploitations such as steam soak, steam flooding, combustion in situ, hot water floodings as main, use and coldly adopt relatively lessly, mainly concentrate on the states such as Venezuela, Canada.The method of heating exploitation is different, but its basic ideas are roughly the same, namely reduces the shaft bottom viscosity of thickened oil, improves the mobility of crude oil, by corresponding artificial lifting way, realizes the purpose of high-efficiency mining.In the heating exploitation process, the injection of steam, deep fat so that temperature in wellbore is in the condition of high temperature (usually up to 350 ℃), seriously reduces underground equipment application life.
