Study On Bottleneck Of Crude Oil Export System And Pipeline Adaptability Measures In XJ Oil Field

In recent years,Petro China has fully implemented the spirit of the country’s important instructions on increasing the exploration and development of oil and gas resources,and has made every effort to ensure the safety of national oil and gas supply.XJ Oilfield,as the main area of crude oil exploration and development in the western region of Petro China,highlights high-quality development,accelerates the construction of modern large oil and gas fields,and plays a backbone role for the group company in maintaining the effective and stable production of 100 million tons of domestic crude oil and ensuring national energy security.According to the plan,during the period 2020-2025,the XJ oil field plans to increase crude oil production from 13.18 million tons to 15.8 million tons.The MH oil field is the new main area for the XJ oil field to increase crude oil production.During 2020-2025,the crude oil output will increase from 2.04 million tons.Tons increased to 5.07 million tons.In recent years,crude oil production in the abdomen and eastern regions of XJ Oilfield has continued to decline,making pipeline distribution less than the designed minimum delivery volume,leading to a greater risk of safe operation of the crude oil pipeline system in this region under the current operating mode.In the face of the rapid growth of crude oil production in MH oilfield and the continuous decline of pipeline tasks in the eastern part of the belly,the crude oil transportation system of XJ oilfield will face huge economic and safe operation challenges if effective measures are not taken.Therefore,it is urgent to sort out and analyze the bottleneck problem of the crude oil transportation system in XJ Oilfield,and propose countermeasures to improve the adaptability of the corresponding pipelines,to ensure that the allocation of oilfield resources is optimized and the production path of XJ Oilfield is unblocked.In order to solve these technical problems that severely restrict the production,transportation and marketing of crude oil in XJ Oilfield,realize the safe,efficient and flexible operation of crude oil pipelines,and ensure the maximum economic benefits of XJ Oilfield.The current situation of transportation and sales,in accordance with the principle of optimizing the value of the upstream and downstream integrated industrial chain,and considering the overall distribution of crude oil and the corresponding pipeline task delivery volume,analysis of the KDD377 pipeline transportation volume needs to be improved;SC line,CH line,HS line low-volume operation,Can not meet the more prominent bottleneck problems of export,such as safe transportation requirements.Through the combination of theory and practice,research the KDD377 pipeline,KD three pipes in parallel to increase the transmission,and use the pour point depressant to return temperature and return the characteristics,one-stop dosing Solve the problem of low transmission volume of SC line,CH line and HS line,and ensure the safe,economical and efficient operation of crude oil transmission channel between XJ Oilfield and downstream petrochemical companies.At the same time,the income from integrated pipeline transportation and oil payment is expected to increase by more than 16 billion yuan in XJ oilfield during 2020-2025.
