摘　　要：该文采用水力热力分析的方法研究了BZ26-3至BZ26-2海底输气管道反向输油的可行性。结果表明,海底输气管道反向输油是可行的,为了满足海底管道安全输送要求,需要BZ26-2油气田与BZ13-1区域的混合原油不脱水直接输送,加注降凝剂使所输原油凝固点不高于18℃以及原油最小输量为588m3/d。海底输气管道反向输油过程中可能出现BZ13-1油气田、BZ26-2油气田或BZ26-3油田停产的工况,因此需要分别采取掺水输送和加热输送的应对措施。The feasibility of crude oil reverse transportation through submarine gas pipeline from BZ26-3to BZ26-2for 22 dhas been studied with hydraulic and thermal analysis.The results show that this measure is feasible,to meet the requirements of the submarine pipeline safe transportation,it demands that the mixed crude oil of BZ26-2oil-gas field and BZ13-1region is not dehydrated、pour point depressants are injected into the submarine pipeline to make pour point of transportation crude oil no more than 18℃ and the minimum throughput of the submarine pipeline is 588m3/d;BZ13-1oil-gas field、BZ26-2oil-gas field or BZ26-3oilfield is likely to stop production during the submarine pipeline reverse transportation,the countermeasures of blending water transportation and heating transportation have to be taken respectively at that time.
