Description
Technical field
The present invention relates to oil is carried out on hydraulic well repairing device on a kind of offshore oil platform more particularly to offshore oil platform
The hydraulic device of tubing string is promoted and transferred in well shaft.
Background technique
During marine petroleum development, for part marginal oil field, small-sized offshore platform is mostly used to develop, platform is not provided with
Fixed well repairing device such as platform drilling machine, platform workover rig etc., when needing to carry out workover treatment in oilfield process, needs to move
Workover treatment is carried out with the mode of large-scale mobile well repairing device.
Large-scale mobile well repairing device such as self-elevating drilling platform etc., workover cost is higher, and it is more difficult that platform resource is coordinated,
It will appear the case where field output is influenced not in time due to well workover.
Summary of the invention
In view of the above-mentioned problems, avoiding employing the object of the present invention is to provide a kind of offshore platform Simple hydraulic workover rig
The case where high cost of movable well repairing device bring, low income.
To achieve the above object, the present invention use following technical scheme, a kind of offshore platform Simple hydraulic workover rig,
It is characterized in that, including pedestal and is adjacent to fixed two days mechanism of car on the base；
Each day mechanism of car includes:
Hydraulic drive mechanism, the output end of the hydraulic drive mechanism are in be arranged upward vertically；
Its kickstand is fixed on the top of the output end of the hydraulic drive mechanism；
Crown sheave group is rotatably arranged on the day kickstand,
Rope group, one end of the rope group is fixed on the base, and the other end of the rope group is across the crown sheave
Group is connect with hook block.
Preferably, the pedestal is fixed in preventer group, and the preventer group is connect with marine riser, the pedestal
It is connect by guy wire with platform main deck.
Preferably, the hydraulic drive mechanism uses hydraulic cylinder, and the hydraulic cylinder is fixed on the base vertically, and institute
The piston rod for stating hydraulic cylinder is arranged upward vertically.
Preferably, the crown sheave group is two pairs of pulleys for being distributed in the two sides of the day kickstand, and each pair of pulley is logical
Shaft is crossed to be fixed on the day kickstand；Rope group includes two big rope, and every one end restricted greatly is fixed on the base, separately
Two pulleys of one end across ipsilateral distribution are connect with the hook block.
The invention adopts the above technical scheme, has the advantages that the present invention includes pedestal and is fixed on the base
Two days mechanism of car, pass through the reciprocating motion of the output end of two hydraulic drive mechanisms on two days mechanism of car, drive hook block
It moving back and forth, and then realizes tubing string removing in well wellbore, entire workover rig structure is simple, and small in size, working area is small,
Overall weight is light, and it is higher to remove efficiency.
Detailed description of the invention
Fig. 1 is positive structure diagram of the invention；
Fig. 2 is side structure schematic view of the invention；
Fig. 3 is overlooking structure diagram of the invention.
