Description
Technical Field
The invention relates to a power cable, a hydraulic control pipeline and a guiding device of a data transmission line of an operation and construction well of an electric submersible pump in the petroleum industry, in particular to an auxiliary installation device of a well completion cable of the electric submersible pump and a using method thereof.
Background
Along with the gradual development of offshore oil fields, the number of oil-water wells and the operation workload are increased year by year, and as the offshore crude oil exploitation is influenced by factors such as the size of an offshore platform, the tidal flow direction, the power supply voltage level, the input-output ratio and the like, the crude oil is exploited, except for the self-injection exploitation, the mechanical exploitation mode adopts an electric submersible pump for exploitation. In addition, the offshore environment determines that the safety and environmental protection requirements are high in level, and the well completion process of the offshore environment needs to adopt a plurality of well control measures, wherein a downhole safety valve, a cable-passing packer and a hydraulic control annulus packer are main measure tools of the well control measures. The well control measure tools are all matched with 1/4 in-size hydraulic control pipelines, and according to the requirements of development technology, 3/8 in-size hydraulic control pipelines and 1/4 in-size data transmission signal cables are required to be inserted in some cases. According to the construction design requirement, all cables in the well completion operation of the submersible electric pump are fixed on a well completion pipe column through a cable guide wheel and then are put into a well.
The cable guider used by the existing electric submersible pump well completion traversing cable consists of a cable guide wheel clamping plate and a cable guide wheel, wherein the cable guide wheel is arranged between the two cable guide wheel clamping plates through a wheel shaft and can only traverse the cable and can only traverse a flat cable. If the power cable passes through the hydraulic control pipeline at the same time, the power cable is easily twisted and extruded due to different curvatures of various cables caused by different hardness of the hydraulic control pipeline and the cable.
In order to guide the power cable, the cable guide pulley is hung at the open crotch of the derrick. Before the completion construction of the electric submersible pump, one end of a power cable of the electric submersible pump is lifted manually to pass through a cable guide wheel by climbing to the suspension part of a cable guide wheel device of a derrick. When the cable packer is lowered in the well completion construction, the cable at the end part of the residual power cable coiled by the cable drum needs to integrally pass through the cable packer penetrator, and at the moment, 2 times of leading in and leading out of the cable passing through the cable packer and other hydraulic control pipelines are needed. Other hydraulic control pipelines and cables need to penetrate into the cable guide wheel at the same time, and the power cables are easily twisted and extruded due to different degrees of curvature of various cables caused by different hardness of the hydraulic control pipelines and the cables.
Above-mentioned operation construction, because derrick crotch and carousel central point horizontal distance are great, constructor uses the protector with the cable to fix the in-process at completion tubular column oil pipe outer wall, needs constructor to promote the cable until laminating oil pipe outer wall, causes power cable to bear the pulling force buckling deformation easily, influences construction quality. In the construction, the labor intensity of constructors is high, the number of the participated constructors is large, the construction safety risk is high, the problems that cables are damaged by extrusion and the like exist, and the construction safety and construction quality hidden danger are high.
In the prior art, various cable guide wheel devices are provided, but the cable guide wheel device for well completion of an oil-submersible electric pump in the petroleum industry is rarely disclosed. Such as the following:

CN201910039433.0 discloses a fire-proof and corrosion-resistant cable bridge and a manufacturing method thereof, which is a cable bridge that avoids damage to internal cables caused by direct contact with high-temperature objects, reduces drag force when cables are dragged, and reduces abrasion on the cable surface. The forming of the bridge frame main body is completed by the cold-rolled steel plate through stamping and bending welding procedures, the integrity of a zinc coating can be kept by galvanizing and spraying paint after welding treatment, damage to the zinc coating in the operation process is avoided, and the corrosion resistance of the internal cold-rolled steel plate is guaranteed. The cable guide wheel is a component of the bridge frame, and is a technology for manufacturing the existing cable direct bridge frame together. The simultaneous crossing construction of a plurality of cable hydraulic control pipelines and the crossing construction of well completion cables of the offshore submersible electric pump cannot be met.
CN201721733027.7 discloses a "shaft cable laying device", which is a device for making cables more stable during paying off by using a gravity buffering device, so that cable laying in a shaft is more orderly, and maintenance and overhaul of cables are facilitated. Its structure includes square support, the hoist engine is installed to square support bottom, install cable gravity buffer and pay-off in the square support, the hoist engine top is equipped with surely slides the guide pulley, the hoist engine has the steel wire lifting rope through the reel coiling, the top of steel wire lifting rope is connected with the suspension hook, cable gravity buffer includes the horizontal support pole, install the cable guide pulley on the horizontal support pole, pay-off rack and gear, rack one side is connected with the mount pad, install the telescopic link on the mount pad, the telescopic link is connected with half-circle ring anchor clamps, it is bulky and need the horizontal direction to place the cable.
