Example Embodiment

[0017] In order to enable those of ordinary skill in the art to more clearly understand the purpose, technical solutions, and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Such as Figure 1-2 As shown, the design method of a pipe jacking tunnel crossing project based on water filling operation for oil and gas pipeline waters in the present invention includes the following steps:

[0019] (A) In view of the complexity of pipeline installation of pipe jacking tunnels in waters, specific classifications are made on the methods of operation after pipeline installation, and a practical filling method is proposed based on the classification situation. The filling method is water filling operation, which is effective in monitoring natural gas While leaking, fix the pipeline to prevent the pipeline from instability, and ensure that it can enter the tunnel again for maintenance...

Abstract

An oil and gas pipeline water area pipe-jacking tunnel crossing engineering design method based on water filling operation comprises the following steps that (a) classifying operation methods after pipeline installation according to the complexity of water area pipe-jacking tunnel pipeline installation, and a filling method conforming to the reality is provided according to the classification situation; (b) fully considering the influence of water filling operation on pipeline operation, and providing a pipeline installation method and a support hanger design scheme suitable for the water filling operation working condition according to the influence; (c) proposing a corresponding design calculation method for pipeline installation and corrosion prevention according to the requirements ofunderwater safe operation of the pipeline; and (d) proposing a pipeline overhaul and maintenance method according to the requirements of long-term overhaul and maintenance; according to the characteristics of a water area pipe-jacking tunnel crossing project, a design method of water-filling operation in a tunnel is described in detail, an excellent plugging method is provided for the oil and gaspipeline water area pipe-jacking tunnel crossing project, and an effective means is provided for operation and protection of the oil and gas pipeline water area pipe-jacking tunnel crossing project.

Description

technical field [0001] The invention relates to a water-filled operation-based engineering design method for pipe-jacking tunnel crossing in oil and gas pipeline waters, and belongs to the technical field of oil and gas pipeline crossing engineering. Background technique [0002] With the improvement of my country's requirements for the safety, environmental protection and sustainable operation of long-distance oil and gas pipelines, pipeline operation and management companies need to strengthen the control of investment costs in the entire life cycle of construction projects, and various problems that arise during pipeline operation should be repaired by pipeline operation and management companies Maintenance presents great challenges. Usually, large and medium-sized crossing projects, as control projects for long-distance oil and gas pipelines, are generally located near important transportation facilities, rivers and lakes, and the existing mainstream construction method i...
