All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

102. acquiring a response equation of logging according to the first correlation relation and the second correlation relation;
103. and quantitatively calculating the gas-oil ratio based on the response equation of the logging and the gas logging information.
It should be noted that the execution subject of the embodiment of the present invention is a computer software program pre-stored in a computer device, and the implementation scenario is an application of a gas logging technology, it can be understood that a response characteristic of a conventional oil and gas reservoir and some critical oil reservoirs on logging or logging has a certain similarity, and it is difficult to quantitatively distinguish complex reservoir fluids by using a conventional logging method or a single logging method alone.
To address the above scenario, specifically, in step 101, an embodiment of the present invention provides two gas-oil ratio calculation manners, where the first is to select and establish a correlation according to gas measurement parameters that can embody fluid characteristics, the established correlation is a first correlation, and the second is to introduce and comprehensively utilize derivative parameters of a light hydrocarbon component and a heavy hydrocarbon component of each hydrocarbon reaction fluid to establish a correlation, and the established correlation is a second correlation.
Further, in step 102, a response equation of logging may be written by using different correlation relationships between the gas logging parameters and the derived parameters, and the gas-oil ratio may be calculated by using the gas logging data through the simultaneous association of the obtained logging equation and the response equation of logging by combining with the formation composition analysis program and the optimization theory.
Finally, in step 103, the gas-oil ratio is calculated quantitatively by converting the volume of the gas under the underground condition to the surface condition according to the equation of state of the gas to obtain a gas-oil ratio calculation formula.
According to the state equation of the natural gas, the state equation of the natural gas under the ground condition is written as follows:
P gm V gm ＝z m NRT m
wherein N is the mole number of the gas, and the unit is mol; p gm 105Pa, which is the pressure of the gas under ground conditions; v gm Is the volume of gas under ground conditions, in units of L; t is m Is the absolute temperature of the gas in K; r is a general gas constant and has the unit of J.mol -1 ·K -1 ；z m Is the compression factor, dimensionless, z, of the gas under surface conditions m ≈1。

For fluids such as volatile oil layers and condensate gas layers similar to conventional light oil and gas layer properties, in order to accurately judge the critical fluid properties, according to widely used derived parameters and fluid gas measurement characteristics in research areas and the completeness of each hydrocarbon component, the embodiment of the invention introduces derived parameters H representing the relative content of heavy hydrocarbon components by utilizing C1, C2, C3 and C4 a And embodies the light hydrocarbon groupDerived parameters H in terms of relative content b They are defined by the following formula:
