Oil gas wildcat screening method

Abstract

The present invention discloses a method for screening an oil gas wildcat target. The method comprises the following steps: obtaining a drilling success probability of a to-be-screened wildcat target and recoverable resource amount; obtaining a development risk scale of the to-be-screened wildcat target based on the drilling success probability and the recoverable resource amount; determining a threshold of the development risk scale based on an exploration target; and screening according to the threshold of the development risk scale, so as to obtain a wildcat target. According to the wildcat target screening method disclosed by the present invention, optimization of wildcats with different regions, different fields and different resource types on a unified platform can be realized, and not only operability and practicality of the screening method can be significantly improved, but also human subjective influences during a screening process are maximally reduced, and more reliable bases are provided for determination of a wildcat deployment direction and sequence, exploration investment optimization and layout plan making in an oil company.

Description

technical field [0001] The invention relates to the field of oil exploration, in particular to a method for screening oil and gas pre-exploration wells. Background technique [0002] In the process of oil exploration, oil companies need to select favorable exploration targets to drill oil and gas pre-exploration wells from a large number of candidate pre-exploration well targets before actual drilling, so as to make unified decision-making and deployment, and specify the direction and sequence of pre-exploration well deployment. The screening of preexploration well targets is the basis and key for oil companies to formulate annual exploration plans, medium and long-term planning and exploration project management. [0003] In the prior art, domestic and foreign oil companies usually use the method of screening traps to screen prospecting wells. At the same time, the existing screening methods generally have problems such as the parameter system is not uniform, and the assig...
