Abstract
The utility model relates to a sealing ring which is composed of a rubber inner core and a flexible graphite layer which is compounded outside the inner core. The sealing ring can be used for oil production machines in an oil well and other similar devices. The utility model has the advantages of long service life and high temperature resistance. The sealing ring does not need to be replaced during the busywork of gas injection. After the busywork of gas injection is finished, a machine with the utility model does not need to be cooled to a normal temperature, and the machine can be started to extract oil.
Description
The utility model relates to a kind of seal ring, the used seal ring of especially a kind of well recovery machine.
The seal ring that uses in the well recovery machine is rubber ring at present, there is working life short (using continuously about a week), the deficiency of using in the time of can only recovering the oil at normal temperatures, and in the oil producing operation especially when the viscous oil area operation, often need again toward the down-hole gas injection, the reason of the high temperature during owing to gas injection, need when gas injection, rubber ring to be pulled down, change the carbon fiber seal ring, change rubber ring in the time of need being cooled to normal temperature after gas injection finishes again and could continue oil pumping, whole process wastes time and energy, because carbon fiber seal ring price is very high, and only use and once just scrap, thereby also increased cost for oil production.
The purpose of this utility model provides a kind of seal ring, can use in normal temperature recovers the oil, and long service life can be used when gas injection again, just can realize the start oil producing operation simultaneously under higher temperature.
The utility model comprises rubber inner core, and rubber inner core is compounded with the Expanded graphite layer outward, and inner core described in the utility model is preferably the rubber material of the better and certain high temperature of ability of elasticity.
The utility model structure and preparation process are all very simple, because the effect of outside Expanded graphite composite bed, make the big reduction of friction factor, and has high-temperature resistant result, thereby prolong working life, reduce the replacing number of times of seal ring, the oil pumping of just can starting shooting when oil reservoir is cooled to 70 ℃ after gas injection finishes has improved oil recovery efficiency.
Below in conjunction with accompanying drawing the utility model is illustrated.
Accompanying drawing is the utility model structural representation.
The utility model is made of a rubber inner core (2) and the Expanded graphite layer (1) that is compound in the inner core outside, inner core is preferably the rubber material of the better and certain high temperature of ability of elasticity, outside composite bed is an Expanded graphite, also claim expanded graphite, Expanded graphite adopts mould pressing method to be compound in the inner core external surface layer.
Claims (1)
- A kind of seal ring comprises rubber inner core, it is characterized in that rubber inner core is compounded with the Expanded graphite layer outward.
