abnormal pressure formation的意思|示意

Abnormal high formation pore pressure and sloughing stress exist in the south area of Junggar Basin, and mud making and composite ion contamination is also remarkable in this area.

新疆准噶尔盆地南缘地区安集海河组存在超高压、强造浆、强坍塌应力、复合离子污染等问题。

There is close relationship between the abnormal high pressure and the gas formation, migration and accumulation.

该区超压分布具有明显的分区性，异常高压与天然气的生成、运移、聚集和成藏有着密切的联系。

This well is characterized by deep drilling horizon and varied formation lithology, so its predrilling prediction of abnormal pressure is the most significant.

该井钻探层位深、地层变化大，钻前异常地层压力预测尤为重要。

Abnormal formation fluid pressure often exists in oil-gas bearing basin.

地层流体压力异常是含油气盆地存在的一个普遍现象。

Reservoir pressure can be divided into normal pressure, abnormal high pressure and abnormal low pressure in terms of the ratio between formation pressure and hydrostatic pressure.

根据地层压力与静水压力的比值大小，可将地层压力分为异常高压、异常低压和正常压力三种压力状态。

Real-time lithology identification while drilling not only helps to find the oil-bearing layers, but also provides a geological basis for the abnormal formation pressure forecast.

利用随钻工程参数进行实时识别岩性研究，既有助于钻井过程中及时发现油气层，又能为及时的地层异常压力预报提供地质基础；
