| Summary: | At the end of 2020, the P oil layer in area B had proved geological reserves * million tons, developable geological reserves * million tons, and proved developable reserves * million tons. It is estimated that by the end of 2022, the developable reserves will be * million tons, the remaining developable reserves * million tons, of which * million tons are to be written off, and the undeveloped reserves after written off will be * million tons, and the developable rate of P oil reservoir reserves will reach 96.7%. In the absence of large-scale development in the Fuyu oil layer, it is a problem that must be solved to find the potential of infrastructure in the P oil layer. Completed-nonproducing wells mainly refer to those have not been put into production after completion of drilling. The potential of not constructed after completion of drilling mainly starts from the nature of the oil and water developed in a single well and the thickness of the reservoir, combined with the position relationship of the well and the relationship between injection and production, to analysis the development potential as oil- water wells or lifting wells.
