Problems solved by technology

[0003] However, carbonate buried hill oil and gas reservoirs have strong heterogeneity, and even in similar parts inside the same buried hill, the oil and gas bearing properties will be very different. Therefore, if only from the perspective of the entire trap and Unable to accurately determine the hydrocarbon-bearing properties of carbonate buried hill reservoirs

Abstract

The invention provides a method and device for determining oil-gas possibility of a carbonate rock buried hill. The method comprises the steps of calculating a phase index according to rock core measured data and logging data; calculating a potential index; calculating a phase and potential coupling index according to the phase index and the potential index, and calculating a source control index; calculating a phase and potential source control oil-gas effect index according to the phase and potential coupling index and the source control index; and determining the oil-gas possibility of the carbonate rock buried hill according to the buried hill single well productivity and the phase and potential source control oil-gas effect index. According to the method and the device, the technical problem that the oil-gas possibility of the carbonate rock buried hill cannot be accurately judged in the prior art is solved, the technical effect of accurately judging the oil-gas possibility of the carbonate rock buried hill is achieved, exploration risks are reduced, and the oil-gas drilling success rate is improved.

Description

technical field [0001] The invention relates to the technical field of oil and gas resource evaluation, in particular to a method and a device for determining the oil and gas content of buried hills in carbonate rocks. Background technique [0002] At present, the two parameters of trap fullness and reservoir oil saturation are mainly used to evaluate the oil and gas of oil and gas reservoirs. In the evaluation process, the concept of area fullness coefficient in the calculation of resources is mainly used. The enrichment and oil-gas-bearing properties of traps are not distinguished, and the two are mixed together for research and discussion. Most of the research is qualitative. It is believed that in oil-gas-rich areas, the filling coefficient is generally higher, while in oil-gas-poor areas, The fill factor is lower. [0003] However, carbonate buried hill oil and gas reservoirs have strong heterogeneity, and even in similar parts inside the same buried hill, the oil and ...
