Method and apparatus for determining oil output quantity and gas output quantity of shale oil in-situ conversion

A method for determining a gas output quantity of a shale oil in-situ conversion, comprising:

• obtaining a plurality of groups of shale samples of a target stratum of a target area, wherein the shale samples are immature shale samples;
• measuring the plurality of groups of shale samples to obtain an initial TOC parameter, an initial Ro parameter, and an initial HC parameter of each group of shale samples in the plurality of groups of shale samples;
• determining, according to the plurality of groups of shale samples, a first retained gas quantity, a Ro parameter, a gas output quantity and a second retained gas quantity of each group of shale samples in the plurality of groups of shale samples under each preset temperature;
• building a gas output quantity model according to the first retained gas quantity, the Ro parameter, the gas output quantity and the second retained gas quantity of each group of shale samples in the plurality of groups of shale samples under each preset temperature;
• determining a gas output quantity of the target stratum of the target area according to the gas output quantity model.
