Embodiment 1

[0048] This embodiment is a method for evaluating the safety of beach and land shore facilities, which is characterized in that it includes the following steps:

[0049] Step 1: Fully collect survey and design, engineering geology, construction and construction, completion acceptance, operation management, maintenance and reinforcement, and marine environment observation data, among which, the necessary basic data parameters are obtained through necessary exploration, measurement, testing and testing methods, as shown in Table 1 shows:

[0052]

[0053] Step 2: Check the existing island body and embankment, including inspection of the face protection structure such as the frontal surface, the top surface of the island body, and the top surface of the embankment, the bottom protection measures for the island body and the sea entry road, the junction of the sea entry road and the island body, The material strength and d...

Embodiment 2

[0277] In step 6, according to the characteristics of the sea area near the beach and land and the artificial island project, the wave, water depth characteristic data, seabed soil properties and other marine environment characteristic parameters related to the project area are collected, and the actual scour depth and range near the project are detected Data or numerical simulation of erosion and deposition thickness evolution prediction data and island body (embankment) structural characteristics and other parameters. Analyze the above basic data to obtain relevant parameter indicators, such as wave parameters: effective wave height H in front of the embankment, effective period T, wavelength L, water depth h in front of the embankment; soil parameters: shear modulus G of the soil, saturation Sr, internal friction angle Soil cohesion c; actual structural parameters of the island. Engineering structural parameters: the actual structural parameters of the island body.

Abstract

The invention discloses a beach-sea-land-shore petroleum facility safety evaluation method. The method includes: aiming at the characteristics of beach-sea-land-shore and artificial island facilities,sequentially performing overtopping safety evaluation on the beach-sea-land-shore and artificial island facilities due to special geographical and geological conditions, and evaluating the stabilityof the surface protection dimension stone and the stability of the bottom protection dimension stone under the satisfied condition; evaluating the overall stability of the beach-sea-land-shore and artificial island facilities; and evaluating the risk of the beach-sea structure under the action of the earthquake load, thereby comprehensively evaluating the safety of beach-sea-land-shore and artificial island facilities. The scheme has the beneficial effects that according to the description of the scheme, help is provided for taking further protective measures, and a scientific basis is provided for beach-sea-land-shore oil facility construction.

Description

technical field [0001] The invention relates to the field of oil production safety, in particular to a method for evaluating the safety of beach and land shore facilities. Background technique [0002] Oil resource collection in coastal and shallow sea areas faces a different geographical and geological environment from that of the land oil mining industry, which also means that in the consideration of safe production, some risk factors brought about by unique geographical and geological environments should be expected. As far as the current situation in my country is concerned, the coastal and shallow sea areas of the Yellow River Delta is an area rich in oil and gas resources, and it is also the largest delta with the fastest progradation in the world. [0003] For oil facilities in coastal and shallow sea areas, the section stability of coastal and artificial island projects is mainly related to parameters such as section structure form, embankment crest elevation, water ...
