The oilfield distribution network has been in operation for a long time,the equipment and facility are aging,and the access of large loads such as electric network drilling rig and electric-pressure driven water injection has brought new challenges to the oilfield distribution network.As a result,the access of electric network drilling rig and electric-pressure driven water injection to the oilfield distribution network was studied.The general situation of operation was discussed,the 6 kV~10 kV distribution network and the influence of the access of electric network drilling rig and electric-pressure driven water injection were analyzed.The main experience and practice were introduced,and the relevant measures and suggestions were put forward.
