Abstract
The utility model relates to a high-temperature and high-pressure packer which comprises a central pipe, a stainless steel cylinder, an expansion rubber pipe, an upper pipe connector, an upper floating connector, a lower pipe connector, a lower floating connector, a centering device and a one-way valve body. The high-temperature and high-pressure packer is characterized in that the stainless steel cylinder is arranged outside the central pipe, the upper end of the stainless steel cylinder and the central pipe are fixed together through the upper pipe connector, the upper portion of the upper pipe connector is provided with the upper floating connector, the lower end of the stainless steel cylinder and the central pipe are fixed together through the lower pipe connector, the lower portion of the lower pipe connector is provided with the lower floating connector, the expansion rubber pipe is arranged outside the middle of the stainless steel cylinder, the lowermost end of the central pipe is provided with the centering device, the diameter of the lower end of the centering device is large, the diameter of the upper end of the centering device is small, and the upper end and the lower end of the central pipe are connected with oil pipes. The high-temperature and high-pressure packer has the advantages that borehole operation is stable, operation is easy, multiple steps of borehole operation can be completed at a time, and convenience and practicability are achieved.
Description
Technical field
The utility model relates to oil exploitation industry, and a kind of HTHP packer, is applied to oil underground operation tool specifically.
Background technology
The packer using in prior art effect in the time of packing is bad, because need to suppress while use always, will bounce back as long as one stops suppressing expanded rubber, operating efficiency is poor, and packer toward down-hole place in, crank, packer rocks back and forth, easily wearing and tearing packer external surface, shortens its application life.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of HTHP packer is provided, the utility model solves the technical scheme that its technical problem adopts: structure of the present utility model comprises central tube, stainless steel cylinder, Dilated rubber hose, upper union, upper floating junction, lower pipe connection, lower floating junction, centralizer, check valve body, it is characterized in that central tube is outside equipped with stainless steel cylinder, the upper end of stainless steel cylinder is fixed together by upper union and central tube, upper union top is provided with floating junction, the lower end of stainless steel cylinder is fixed together by lower pipe connection and central tube, the bottom of lower pipe connection is provided with lower floating junction, the middle arranged outside of stainless steel cylinder has Dilated rubber hose, be provided with bottom centralizer at central tube, the lower end diameter of centralizer is large, the upper end diameter of centralizer is little, the connected pipes of two ends up and down of central tube.
Using method: first oil mine is detected; after having detected, determine the position that needs packing; then packer is extend into appropriate location in mine; suppressing; suppress by water filling or injection liquefied natural gas; the liquid injecting enters central tube; valve body from central tube flows in stainless steel cylinder; suppress by continuing filling liquid; stainless steel cylinder is expanded; the rubber tube in stainless steel cylinder outside is for the protection of stainless steel cylinder, the wearing and tearing when reducing stainless steel cylinder and expanding and between mine wall.Multiple packers can be connected as required, in succession putting into mine needs the position of packing, then carrying out filling liquid suppresses, can once complete multiple tracks underground work, packing from top to down, is provided with safety valve between adjacent packers, after the complete first of packing, pressure reaches certain numerical value, the safety valve explosion of first packer, automatically opens and carries out second packing operation, carries out successively until work complete.
The beneficial effects of the utility model are that the utility model underground work is stable, simple to operate, can once complete multiple tracks underground work, convenient and practical.
