摘要
分析了形成异常地层压力的主要原因,指出异常地层压力的地震预测方法主要是经验公式计算法和等效深度法。通过对吐哈盆地几个区块求取经验系数,并对数十口探井用经验公式法进行预测和对比,表明其相对误差范围都在10%以内。在小草湖和胜北地区利用等效深度法建立正常压实趋势线进行压力预测,其误差范围也在10%以内,能满足工程的要求,证明地震经验公式和等效深度法的预测方法效果都十分理想。
The causes of creating abnormal formation pressure was analyzed. It was pointed out that empirical equation method and equivalent depth method were the major methods for seismic prediction of abnormal formation pressure. These are used for deriving empirical coefficient of blocks of Tuha Basin and the empirical equation method is employed to predict and contrast tens of exploration wells, with relative error within 10%. The equivalent depth method is used to establish normal compaction trend line for pressure prediction in Xiaocaohu and Shengbei Areas, its error is within 10%. It can meet the engineering requirements, it shows that the empirical equations and equivalent depth methods have good application effects.
