Abstract

The invention provides a method and apparatus for determining an entrapment geological resource amount. The method comprises: an entrapment effective volume and a unit reserve factor are obtained; and according to the entrapment effective volume and the unit reserve factor, calculation is carried out to obtain an entrapment geological resource amount being a product of the entrapment effective volume and the unit reserve factor. According to the method provided by the invention, the entrapment geological resource amount can be calculated only by obtaining the ntrapment effective volume and the unit reserve factor, so that a defect of a large calculation result offset caused by inaccurate obtaining of an entrapment geological resource amount calculation parameter can be overcome. Therefore, a solid foundation is laid for objective and reasonable estimation of the entrapment geological resource amount and exploitation plan formulation and exploitation investment decision making can be carried out conveniently.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration, in particular to a method and device for determining the amount of geological resources in traps. Background technique [0002] Estimating the geological resources of traps is the main task of evaluating the potential of drilling targets. Although the volume of oil and gas contained in traps exists objectively, due to the limitations of existing technology and economic conditions, it is impossible to directly measure the volume of oil and gas in the exploration stage. Only indirect means can be used to obtain relevant geological parameters of traps and estimate the amount of geological resources in traps. Therefore, choosing a reasonable calculation method and objectively and quantitatively evaluating the oil and gas scale of traps are the core of trap resource estimation. In the early stage of exploration, due to the lack of geological data, it is difficult to obtain accurate ca...
