In the later stage of the production and development of HB Oilfield, the oil reservoir fluid type is complex.With the development of multi-layer system.The reservoir variables between different types of oil and gas reservoirs are large, and the relationship between oil and water is complex.Most main oil layers have high water drives, and the actual application problem of complex in the formation water mineralization, the surplus oil distribution is complicated.It is iphone 14 price arizona highly distinguished by low-facing and low mineral layers in low pores.

The property is characterized by reservoir fluid analysis evaluation.During the interpretation process, the influence of the wellbore, invasive belt is eliminated, and the accuracy of the capture of the cross-section curve is guaranteed, and related parameters such as reservoir, oil-containing saturation degree gotrax handlebar can be accurately and reliably.The accuracy of oil-water layer recognition has been increased to 80%, and the coincidence rate of saturation interpretation has been greatly improved.
