Field crude oil storage and transportation method for shallow water oil field

Abstract

The invention relates to a field crude oil storage and transportation method for a shallow water oil field. The field crude oil storage and transportation method adopts upper layer unit blocks, a jacket and a storage and transportation boat, wherein the top of the jacket adopts an open jacket structure; the upper layer unit blocks are arranged at the upper end of the jacket; main legs inside the jacket are respectively provided with a plurality of vertical elastic slideways; both sides of the storage and transportation boat are respectively provided with a plurality of anticollision buffers; the surfaces at the front ends of the anticollision buffers are attached to those of the vertical elastic slideways and are used as the joints of the jacket and the storage and transportation boat for connecting the storage and transportation boat and the jacket into a whole in an up-and-down relative sliding manner; and the storage and transportation boat is enabled to be used as a moving carrier capable of entering and exiting the jacket to store and transport field crude oil. According to the invention, the storage and transportation boat and the jacket can be connected into a whole in the normal production state and rapid connection and separation can be automatically carried out between a fixed oil production platform and the moving storage and transportation boat; and safety of production and oil storage is improved and potential safety hazard of production and oil storage is avoided.

Description

technical field [0001] The invention relates to a method for on-site crude oil storage and transportation, in particular to a method for on-site crude oil storage and transportation in shallow water oil fields. It belongs to the field of marine engineering technology. Background technique [0002] At present, in shallow waters, there are many small marginal oil fields with proven reserves (the recoverable reserves of a single oil field are about 100,000 tons to 2 million tons). Due to the high development cost of a single oilfield and the scattered distribution of small marginal oilfields, it is not conducive to the overall joint development of multiple oilfields; if the traditional marginal oilfield development method is adopted, the initial and overall costs required are relatively high; Therefore, these oil fields have not been developed so far. [0003] Existing marginal oil fields usually involve the following two basic development modes: [0004] (1) Relying on the ...

Problems solved by technology

[0011] The main purpose of the present invention is to overcome the above-mentioned shortcomings existing in the prior art, and to provide a method for on-site crude oil storage and transportation in shallow water oil fields, which adopts the method of combining the on-site oil storage and the transport ship, and the transport ship and the transport ship The jacket at the lower part of the oil production platform is connected as a whole under normal production conditions, which not only improves the safety of production and oil storage, but also avoids potential safety hazards in production and oil storage; moreover, the fixed oil production platform and the storage and transportation ship in motion It can automatically and quickly connect and disengage between the moving ships and fixed oil production platforms; it solves the difficult problem of docking between moving transport ships and fixed oil production platforms, and improves the safety of docking between transport ships and fixed oil production platforms; at the same time, it reduces the initial development costs of shallow water marginal oil fields and daily maintenance costs, enabling the development of many small marginal oil fields in shallow water with proven reserves
