Embodiment 1
[0040] see figure 1 , a method for identifying fluid properties of conglomerate tight oil reservoirs, comprising the following steps:
[0041] Step 1) Select a conglomerate tight oil well MH022 in a target research block, and collect conventional logging curves, nuclear magnetic resonance and other logging data to prepare data for subsequent calculations.
[0042] Step 2) Using nuclear magnetic resonance data, the effective porosity, capillary bound porosity and permeability of the conglomerate tight oil reservoir in the measured area are calculated.
[0043] Step 3) Determine the effective thickness of the reservoir to be measured based on the conglomerate tight oil reservoir parameter standard in the area to be measured, and the standard is the effective porosity of the reservoir Greater than 7, the resistivity RT>30, according to this standard to determine the effective thickness of the reservoir.
[0044] Step 4) calculate oil saturation (So), water saturation (Sw), irr...
