Embodiment Construction

[0051] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies implemented based on the content of the present invention belong to the protection scope of the present invention.

[0052] Such as Figure 4 As shown, the storage and utilization of associated gas in offshore oilfields first needs to estimate the production of associated gas and the demand for associated gas on offshore platforms;

[0053] The estimation of associated gas production is composed of three parts: calculation of associated gas reserves, statistics of associated gas production in similar oilfields, and oilfield production planning and arrangement;

[0054] The calculation of the associated gas reserves is calculated by the formula of the volumetric method, and the scale of...

Abstract

The invention provides an offshore oilfield associated gas storage and utilization method. The method is suitable for storage and efficient utilization of offshore oilfield associated gas. By analyzing the relation between the offshore oilfield associated gas yield and the offshore platform demand quantity, different gas storage types are selected, corresponding associated gas treatment links are designed, and when the yield is far larger than the demand quantity, a floating LNG gas storage is adopted for achieving direct utilization of the associated gas and liquefaction output of surplus associated gas; when the yield is close to the demand quantity, a seabed gas storage is adopted for adjusting supply fluctuation of the associated gas; and when the yield is far smaller than the demand quantity, a floating CNG gas storage is adopted for small-scale associated gas collection and utilization, and by selecting different gas storages, the construction and operation cost can be reduced, and the economic benefits of an offshore platform and the utilization efficiency of the associated gas are improved. The offshore oilfield associated gas storage and utilization method is wide in application range, convenient and fast to use, high in reliability and capable of effectively improving the utilization efficiency of the seabed associated gas and reducing energy waste and environment pollution, and has good application value.

Description

technical field [0001] The invention relates to the field of associated gas storage and application, in particular to a method for storing and utilizing associated gas in offshore oil fields for storage of associated gas in offshore oil fields and utilization of associated gas in offshore platforms. Background technique [0002] Associated gas is natural gas produced with crude oil. After certain treatment, associated gas can be used as fuel gas and has great utilization value. However, due to the mismatch between the output of associated gas in the oil field and the utilization of associated gas, in recent years, the associated gas directly burned or evacuated has exceeded 100 billion cubic meters every year, causing huge direct economic losses and serious air pollution and greenhouse effect. , causing serious harm to human health. Today, with the shortage of fossil energy and the increasingly serious damage to the ecological environment, the economic loss and environmenta...
