Study On The Project Of Oil And Water Displacement In Submarine Pipeline

For the oil and water displacement of usual submarine crude oil and condensate oil pipeline,pipe cleaning pig is often used. But if the pipeline is seriously distorted by other factors,it is very dangerous and difficult to insulate and clean the pipeline through the traditional ways.In order to solve this problem and insure the safety of the submarine oil and gas pipeline repairing operation,in this thesis a new technology is introduced,a new gel is used to insulate the oil and water and displace it. According to the situation of the submarine pipeline of Pinghu oil and gas field,author provide a new method to solve this question through researching the technology of gel abroad and domestic,it includes the research of the gel,the experiment,construction procedure,calculation of construction procedure and choosing the equipment.
