南黄海、东海部分构造地层压力预测

Predicting the Formation Pressure of a Part of Structures in the South Yellow Sea and the East China Sea

南黄海、东海部分构造的8口井采用d_c指数、声波时差法及等效深度和伊顿公式计算出地层压力。此压力与用RFT、DST.LOT等实测所得的结果符合率高。故对该两区可用上述方法作地层压力预测。

The d_e index, acoustic slowness method, equivalent depth and Iton formula are used for 8 wells on a part of structures in the South Yellow Sea and the East China Sea to caiculate the formation pres- sure. The pressure obtained has a good coincidence with the results measured in practice by RFT, DST and LOT etc. therefore the method mentioned above can be used for the two areas to forecast the for- mation pressure.
