Abstract
The invention relates to a conveyable light marine 90t workover rig, consisting of workover equipment modules with each weight controlled within 8t. Slide rails can be arranged according to distribution conditions of well head grooves of a series of marine oil-gas production platforms without a workover rig and flexibly installed and arranged. The workover rig can realize that the traditional spud legs satisfy well workover load requirements and workover operations of all oil-gas production platforms configured with a crane with the hoisting capacity of more than 10t and related well stimulation requirements, and has the advantages of reducing development costs of marginal oil fields at the same time and providing effective means for carrying out tapping potential measures of the similar simple production platforms and eliminating underground potential safety hazards. The workover rig has the characteristics of simple structure, short installation period, wide application, and the like.
Description
Technical field
The invention belongs to the light-duty workover rig of moving of a kind of ocean 90t
Background technology
Along with each Oilfield Group small-block oilfield rolling development project of offshore oil constantly increases, newly the no workover rig wellhead platform quantity on also increases at the same time.Break down after each electric pump well is gone into operation and to wait for self lift type semi girder offshore boring island operation reparation when stopping production, present offshore boring island resource-constrained, prospect pit, producing well workload are big, can't satisfy arrangement of time, and rent offshore boring island and will increase the oilfield operations cost greatly in the production platform workover treatment; Simultaneously, the well stimulation that need implement of no workover rig wellhead platform producing well also can't be carried out because of means are limited.For this reason, we do not have the workover rig wellhead platform at the offshore oil oil gas field and have carried out As-Is analysis, determine research, the light-duty modular type workover rig of moving of design 90t, can satisfy the workover treatment requirement of most oil gas wells, simultaneously, the loop wheel machine requirement of the above hoisting power of 10t (containing 10t) of each production platform common configuration is satisfied in the design of the weight of each module.
Summary of the invention
The purpose of this invention is to provide a kind of light-duty workover rig of moving, by ocean material supply ship is vehicle, satisfy resettlement between the oil production platforms that workover treatment load required, disposed the above hoisting power loop wheel machine of 10t (containing 10t), installation at existing oil and gas wellhead production platform spud leg enabling capabilities, it is big to overcome existing workover rig installation workload, the defective that needs large-scale floating crane to cooperate, save the oil field cost of investment, improve the utilization ratio of workover rig, thereby the workover treatment of the no workover rig production platform of realization requires and designs, builds.
Above-mentioned purpose is to be achieved by such scheme: the light-duty ocean workover rig of moving comprises a mobile seat guide rail, goes up compositions such as moving seat (rig floor), a dynamical system, winch assembly, and liquid gas circuit pipeline is with module arrangement, and the intermodule flexible pipe connects fast.To go up and move the direct seat of seat (rig floor) on the fixed guide that welds on the platform topsides deck, vertical mutually at the guide rail of upper bed-plate with the platform rail distribution arrangement, thus realize that the horizontal and vertical of workover rig moves, to arbitrary well location operation of platform.Each parts of workover rig all adopt modularized design, and the weight of individual module is no more than 8 tons.
According to the workover rig of said mechanism, simple in structure, complete machine is in light weight, can utilize Platform lifting devices to carry out dismounting and resettlement, improves the utilization ratio of workover rig.
The present invention compares with existing traditional ocean workover rig, and the advantage that it had is:
1. by the workover rig lower bottom base of type design, the direct seat of upper bed-plate is on the well head slide rail on the cancellation traditional sense.Because workover rig does not move seat down, designs simplification, complete machine is in light weight, satisfies horizontal and vertical mobile requirement.
2. rig floor structure and main removable workover rig adopt the little module design, and the individual module Weight control satisfies production platform 10t loop wheel machine Capability Requirement below 8t.Can utilize the loop wheel machine of platform to carry out dismounting, save the expense of renting large-scale floating crane, the property moved of workover rig, the utilization rate of raising workover rig, economy greatly improves.
3. can move movable part module and equipment and can disposable shipment finish, improve marine workover treatment efficient greatly with 6000 horsepowers of tugboats.
