Description
Technical field
The utility model relates to a kind of three-port structure; Be applicable in the petroleum and petrochemical sector, need not behind a kind of specifically this three-port structure of employing the component on existing (gas) tree of recovering the oil are carried out any change and can realize that well head passes through the cable of function, the pipeline well head passes through three-port structure.
Background technology
When oil gas field is equipped with situation such as sensor, storm valve, packer, sliding sleeve switch for the down-hole; The hydraulic line that all need the down-hole is used for optical cable, the cable of signal transmission and be used to control downhole tool passes through from well head (gas) tree of recovering the oil; Make downhole cable and pipeline can arrive ground from the down-hole; Carry out encapsulation process to passing through Kong Chu again after passing through completion; To guarantee not reduce after cable and pipeline pass through the sealing grade of well head, this has just proposed to pass through requirement to oil recovery (gas) tree that is installed on well head.
The general traversing method that existing oil gas field is adopted is for passing through cable or pipeline earlier from tubing hanger, pass through accomplish after to carrying out high pressure sealing in the place of passing through; Except from tubing hanger is passed through, also need cable or pipeline being passed through from the production tree upper flange, pass through after the completion and equally high pressure sealing is carried out in the hole of passing through at (gas) tree upper flange place of recovering the oil.
For the oil gas field recited above mode of passing through commonly used, need certain requirement be proposed to tubing hanger and production tree upper flange, require need to be processed with cable the two on or hydraulic line passes through the hole, this just makes needs to customize in the process of (gas) tree is recovered the oil in processing.Oil recovery (gas) tree of installing for existing well head needs transform tubing hanger and oil recovery (gas) tree upper flange as if realizing passing through function, on tubing hanger and oil recovery (gas) tree upper flange, processes in addition and passes through the hole.This mode that tubing hanger is passed through has been destroyed the globality of tubing hanger, will make the overall performance of tubing hanger produce certain decline.
Pass through mode for this kind in addition; Because the part that its cable or pipeline expose is longer; When the external world applies active force for cable or pipeline; Two origin of force of cable or pipeline are respectively that seal place and ground line cable or the pipeline on the production tree upper flange goes into to be located in; Can cause two results like this: the one, cause the improper bending of cable or pipeline, can cause the distortion of cable or pipeline when serious or fracture, this will produce very big resistance to the signal transmission performance of cable and pipeline inner fluid, gas flow; The 2nd, because optical cable receives can produce bending at production tree upper flange place after the external force, this will produce bigger influence to the sealing performance at sealing place, very likely cause seal failure; The 3rd, cable or pipeline that this kind mode of passing through exposes are longer, and this has also just increased the probability that outer bound pair cable or pipeline apply active force, and the possibility that causes cable or pipeline unexpected situation to occur increases.
At present, the well head mode of passing through that does not also have a kind of mode of passing through to adopt to realize behind the three-port structure need not the component on existing (gas) tree of recovering the oil are carried out any change and can realize that well head passes through function.Cable that passes through out for well head or pipeline because protruded length is short and cable or two origin of force of pipeline between be straight line; When the external world applies active force for cable or pipeline; Cable or pipeline can be owing to receiving external force to cause improper bending; Thereby the distortion of cable or pipeline occurs or fracture, this just can not produce very big resistance to the signal transmission performance of cable and pipeline inner fluid, gas flow yet.Cable or pipeline receive can the sealing performance to seals at not exert an influence owing to bending after the external force.The cable or the pipeline that expose of this kind mode of passing through is shorter in addition, and this has also just reduced the probability that outer bound pair cable or pipeline apply active force, and the possibility that causes cable or pipeline unexpected situation to occur reduces greatly.
