校正的地质风险评价模型的建立方法和圈闭评价方法
摘要：
本发明涉及校正的地质风险评价模型的建立方法和圈闭评价方法，将圈闭划分为成功和失败两种类型；根据不同圈闭钻前对应的子因子的初始取值计算对应子因子的污染系数，然后计算对应子因子的权值系数；根据不同圈闭钻前对应父因子的初始取值计算对应父因子的污染系数，然后计算对应父因子的权值系数；最后建立地质风险评价模型。通过校正能够提升地质风险评价模型的准确性，有效解决权值系数依靠主观经验判断定性取值导致模型可靠性差的问题。另外，根据校正后的模型进行圈闭评价，能够对圈闭的评价结果产生积极地影响，保证了开采的准确性，进而提高勘探的准确性，降低出现误判的概率。
摘要（英）：

The invention relates to an establishing method of a corrected geological risk evaluation model and a trap evaluation method. The establishing method comprises the steps of dividing traps into a successful type and a failed type; evaluating the pollution factor of a corresponding sub-factor according to an initial value of the corresponding sub-factor before drilling of different traps, and then calculating the weight coefficient of the corresponding sub-factor; calculating the pollution coefficient of a corresponding parent factor according to an initial value of the corresponding parent factor before drilling of different traps, and then calculating the weight coefficient of the corresponding parent factor; and finally establishing the geological risk evaluation model. Furthermore, trap evaluation is performed according to the corrected model, thereby generating a positive effect on a trap evaluation result, ensuring high exploration accuracy and reducing probability of evaluation errors.
