water drive

Oil displacement efficiency is a significant index in water drive oilfield, and is usually obtained by water drive cores experiments.

The application program can be used to verify water invasion identify; water influx and natural gas reserves of water drive gas reservoir.

Water cut curve is the basic curve used to research the water-yielding rules of the water drive oilfield.

Finally discussed and commented are various effective approaches to enhance water drive recovery efficiency and their developing trend.

Cost of water injection is reduced and oil displacement efficiency is improved by converting water drive to expansion drive.

Through improving water drive effects and reducing decline rate, a production pattern has been provided for the high water-cut reservoirs .

For prolonged waterflood development in Pucheng Oilfield, water drive recovery factor of Oilfield is affected.

The recovery factor of water drive calculated by this method coincides with the data of reservoir performance.

A new method to reasonably select a straight line segment on a water drive curve is developed in this paper.

It has remained a challenge of gas development how to enhance edge water drive gas reservoir recovery efficiency.

It is a problem in primary recovery from water drive reservoirs and during waterflood and enhanced oil recovery.

The development indexes of different development phase must be forecasted in development course of water drive oilfield.

Hot - Water drive is an important method to enhance recovery of high viscous oil, and widely is applied abroad because of less hot loss.

The method of calculating the reserve and water influx of water drive gas reservoir by using material balance method is improved.

Another one is suitable to limestone oil reservoir with bottom water drive.

Nutrient water drive had been applied in the north block of Dagang Kongdian Oilfield in 2001-2004.

Imbibition is important in a water drive reservoir because it can advance or hinder water movement, affecting areal sweep.

In development of oil fields, it is significance to study magnitude of water-drive energy effect on production of oil well.
