PREDICTION METHOD FOR SHALE OIL AND GAS SWEET SPOT REGION, COMPUTER DEVICE AND COMPUTER READABLE STORAGE MEDIUM

摘要

The invention provides a prediction method for a shale oil and gas sweet spotregion,a computer device and a computer readable storage medium, wherein the methodcomprises: acquiring an oil and gas content influencing parameter value, anoil and gasfluidity influencing parameter value and a compressibility influencingparameter value,and production cost data; determining a final produced oil equivalentcorresponding toeach influencing parameter value according to a pre-established final producedoilequivalent prediction model; determining an economic lower limit value of thefinalproduced oil equivalent according to the production cost data; determiningwhether or notthe shale oil and gas region to be predicted is a shale oil and gas sweet spotregion. Theabove technical solution realizes quantitative prediction of a shale oil andgas sweet spotregion, improves prediction accuracy, and provides scientific guidance forshale oil andgas exploration and development.
