Abstract
The utility model relates to the technical field of high-temperature and high-pressure safety blowout prevention of a well mouth of a testing optical cable under a steam injection well for exploring the heating power of thickened oil, in particular to a blowout preventer for testing the dryness of a steam injection well. A metal sealer, a sealing connector, a depressurizing valve, a blowout preventer and a well mouth clamping hoop head of the blowout preventer are sequentially connected, wherein the blowout preventer is respectively connected with a dynamic blowout prevention valve, a static blowout prevention valve and an emergency blowout prevention valve through bolts. By adoption of the blowout preventer, dynamic blowout prevention of the testing optical cable in the lifting and descending processes is realized, the metal sealer and a metal sealing material are employed, and the problem about high-temperature and high-pressure sealing of a thermal recovery well mouth is solved.
Description
Technical field:
The utility model relates to a kind of viscous crude heating exploitation and annotates vapour downhole testing optical cable well head HTHP safety blowout prevention technology field, particularly a kind of notes vapour well mass dryness fraction test preventer.
Background technology:
Vapour pressure mass dryness fraction shaft mouth test HTHP blowout prevention technology is most important under the viscous crude heating exploitation steamed well; It is a key technology of guaranteeing operation of heavy crude heat extraction test safety and thick oil thermal extraction production safety, can accurately judge the heat waste and the net horizontal section heat balance current intelligence of steam through the monitoring of down-hole mass dryness fraction.Yet present notes vapour well mass dryness fraction test preventer can only solve the static blowout prevention of test optical fibre cables when test, can not realize the dynamic blowout prevention of test optical fibre cables in the process of removing.Simultaneously, the encapsulant of existing notes vapour well mass dryness fraction test preventer all is nonmetals, can not satisfy under the thick oil filling steam well steam quality test to the requirement of sealing.
The utility model content:
The technical problem that the utility model will solve provides a kind of notes vapour well mass dryness fraction test preventer; This preventer has been realized the dynamic blowout prevention of test optical fibre cables in the process of removing; Adopt metallic seal device and metallic seal material simultaneously, solved the HTHP sealing problem of thermal production well mouth.
The technical scheme that the utility model is taked is: a kind of notes vapour well mass dryness fraction test preventer comprises metallic seal device, hermetically sealed connector, relief valve and preventer; Metallic seal device, hermetically sealed connector, relief valve, preventer, well head clip head connect in order, and preventer is connected with dynamic blowout prevention valve, static blowout prevention valve, urgent blowout prevention valve bolt respectively.
Relief valve, metallic seal device shell adopt stainless steel 1Cr18Ni9Ti to process, and the encapsulant of metallic seal device adopts gun-metal.
Hermetically sealed connector, preventer, well head clip head all adopt steel 35CrMo to process.
Dynamically blowout prevention valve, static blowout prevention valve, urgent blowout prevention valve all adopt the 16Mn steel to process.
The beneficial effect of the utility model is: the utility model has been owing to adopted preventer and the dynamic bolted mode of blowout prevention valve, thereby has the function of the dynamic blowout prevention of test optical fibre cables in the process of removing; Owing to adopted metallic seal device and metallic seal material, solved the HTHP sealing problem of thermal production well mouth.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Accompanying drawing is the structural representation of the utility model.
The specific embodiment:
Shown in accompanying drawing, a kind of notes vapour well mass dryness fraction test preventer comprises metallic seal device 1, hermetically sealed connector 2, relief valve 3 and preventer 4; Metallic seal device 1, hermetically sealed connector 2, relief valve 3, preventer 4, well head clip head 8 connect in order, and preventer 4 is connected with dynamic blowout prevention valve 5, static blowout prevention valve 6, urgent blowout prevention valve 7 bolts respectively.
Relief valve 3, metallic seal device 1 shell adopt stainless steel 1Cr18Ni9Ti to process, and the encapsulant of metallic seal device 1 adopts gun-metal.
Hermetically sealed connector 2, preventer 4, well head clip head 8 all adopt steel 35CrMo to process.
Dynamically blowout prevention valve 5, static blowout prevention valve 6, urgent blowout prevention valve 7 all adopt the 16Mn steel to process.
Well head clip head 8 is connected with thermal production well mouth during work; Test optical fibre cables is lowered to through metallic seal device 1 and preventer 4 and implements the hot dynamic parametric test in down-hole that thermal production well is annotated HTHP saturated vapour process under the thermal production well; Test optical fibre cables is controlled through dynamic blowout prevention valve 5 in the process of removing; Control through static blowout prevention valve 6 during test; Through urgent blowout prevention valve 7 controls, annotating the vapour well needs long-term continuous monitoring when contingency generation blowout occurring, the sealing through metallic seal device 1 realization test optical fibre cables and thermal production well mouth in testing process.Accomplish test back test optical fibre cables and play well head, close head valve, with the well head pressure release, trip out test optical fibre cables and accomplish test job with relief valve 3.
It is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
