油田进入开发后期，原油产量的压力越来越大，为弥补后备资源的不足，在老油田寻找新储量依然是一项必不可少的工作。老油田内部并密度较大，并网控制程度较高，寻找大型新汕藏的可能性很小，但是找到小目标隐蔽油气藏的可能性还是很大的。老汕田寻找新估量具有较大的潜力，不 As the oilfield enters the late stage of development, the pressure of crude oil production is getting more and more large. To make up for the shortage of reserve resources, finding new reserves in old oilfields is still an indispensable task. The older oilfields are more dense and have a higher level of grid control. The possibility of finding a large new Shantou reservoir is very small, but the possibility of finding subtle subtle reservoirs is still great. Old Shantou to find new estimates have greater potential, no
