Embodiment 1

[0066] The invention provides an offshore oil production platform, such as Figure 12 and Figure 13 As shown, the offshore oil production platform includes: a jacket platform 10A and a water riser 20A, the jacket platform 10A is provided with a guide tank 30A, and the water riser 20A is penetrated in the guide tank 30A; the water riser 20A is connected with The support cylinder 41A, the guide groove body 30A is in contact with the support cylinder 41A, and the support cylinder 41A can exert an upward support force on the guide groove body 30A.

[0067] In this offshore oil production platform, on the one hand, the guide groove 30A can limit the position of the riser 20A in the horizontal direction; The cylinder 41A is connected, and the riser 20A can exert an upward supporting force on the jacket platform 10A, thereby transferring the load of the jacket platform 10A to the riser 20A. The riser 20A itself has a bearing capacity, and by means of load transfer, the riser 20A i...

Embodiment 2

[0078] The structure of the jacket platform 10A and the riser 20A is relatively complicated. In actual working conditions, there are differences in the load distribution of the jacket platform 10A, the way to increase the number of wellheads and equipment, and the way to transform wellheads and equipment. These factors Effects on the load transfer described above will have an effect. At present, it is still difficult to evaluate the load transfer effectiveness and load transfer efficiency of the jacket platform 10A, the mechanical properties of the jacket platform 10A and the riser 20A after the load transfer, which affects the above-mentioned offshore oil production platform capable of load transfer. promotion and application.

[0079] For this reason, the invention provides a kind of experimental system of jacket platform load transfer, such as figure 1 and figure 2 As shown, the experimental system includes: a jacket platform model 10, a riser model 20, a loading system ...

Embodiment 3

[0099] The present invention provides a kind of experimental method of jacket platform load transfer, adopts the experimental system of above-mentioned jacket platform load transfer, such as Figure 19 As shown, the experimental method includes:

[0100] Step S10, installing an experimental system for load transfer of the jacket platform;

[0101]Step S20 , use the loading system 500 to load, and use the load sensor 70 to measure.

[0102] In step S20, using the loading system 500 to load includes loading according to a set loading method. Preferably, the set loading method is load step increase, the loading method includes load step size, number of ballast steps, load stabilization time and maximum load value, and the load step size refers to the incremental amplitude of load step increase, ballast step The number refers to the number of load increments, the load stabilization time refers to the time period during which the load is stable at a step value during the stepwise...

Abstract

The invention provides an offshore oil production platform and a jacket platform load transfer experiment system as well as method. The offshore oil production platform comprises a jacket platform andwater-resisting guide tubes, wherein guide groove bodies are arranged on the jacket platform; the water-resisting guide tubes are arranged in the guide groove bodies in a penetrating manner; at leastone support cylinders is connected with at least one water-resisting guide tubes; the guide groove bodies are propped against the supporting cylinders; and the support cylinders are capable of applying upward support force to the guide groove bodies. Through the offshore oil production platform, the carrying capacity of the jacket platform can be improved, and the technical problem that the carrying capacity of an existing jacket platform can hardly meet the requirements can be alleviated.

Description

technical field [0001] The invention relates to the technical field of offshore drilling engineering, in particular to an experimental system and method for load transfer of offshore oil production platforms and jacket platforms. Background technique [0002] The jacket platform is an important equipment for offshore oil and gas exploration and development. At present, the equipment for offshore oil and gas exploration and development tends to be large-scale and modularized; at the same time, it is required to increase the number of wellheads and equipment for the jacket platform that has been built. The large-scale drilling and development equipment and the increase in the number of wellheads put forward higher requirements on the carrying capacity of the built jacket platform. However, when the existing jacket platform is built, its bearing capacity is usually designed based on the number and specifications of the original wellhead and equipment. When the wellhead and equ...
