Method of post-drilling assessment for the prospect evaluation of petroleum exploration

  • 摘要: 钻后评估是油气资源勘探过程中勘探目标评价活动的重要环节,通过钻前预测与钻后结果对比分析,总结经验,对钻前评价与预测工作中的不足进行不断校正和完善,使勘探目标的钻前评价和预测结果更加准确,进而提高下一步油气勘探的成功率。在介绍钻后评估主要内容和方法的基础上,总结钻后评估中需要重点关注的问题和解决方法。研究认为,在钻后评估中通过分析钻探成功目标和失败目标的地质风险评价结果及资源量计算参数预测结果,比较钻前预测和钻后估算产生较大偏差的关键要素,分析产生偏差的原因并在后续评价中进行重点改进,在提高后续勘探成功率,有效提升地质勘探人员勘探目标钻前评价和钻前预测能力方面有着重要意义。
