随着海上油气田的不断开发,海洋石油的开采逐渐从近海向深海发展,海底油气运输管道已成为广泛用于海洋石油工业的重要运输手段,并且成为连续大量输送油气最快捷、最安全和最经济有效的方式。我国海洋资源丰富,其中石油资源量为240亿t,天然气资源量为14万亿m~3,开发和利用这些资源对于我国具有非常重要的意义,因此国内企业正积极研发海底管线钢。 With the continuous development of offshore oil and gas fields, the exploitation of offshore oil gradually develops from the offshore to the deep sea. The seabed oil and gas pipelines have become an important transportation means widely used in the offshore oil industry and have become the fastest, safest and most economical Effective way. China is rich in marine resources, of which 24 billion tons of oil resources and 14 trillion m3 of natural gas resources. The development and utilization of these resources are of great significance to our country. Therefore, domestic enterprises are actively developing submarine pipeline steel.
