The reservoir is deep-water turbidity deposit. The main sedimentary micro-phased are distributary channels and the side edges of channels. The development target layer is Daling River oil layer. Since 1978, industrial oil flow has been obtained by trial production of Daling River oil layer, and 6 development wells have been put into injection successively, of which 2 wells have achieved good results. In 2020, on the basis of re-understanding geological bodies, four new wells were implemented, and good results were achieved. The successful implementation of the new well is mutually confirmed with geological knowledge, recalculates the oil-bearing area and geological reserves, and prolongs the exploitation period of the block.展开更多
