地层压力的预测方法综述

【摘要】 石油勘探阶段确定地层压力的方法很多,大体上可分为钻井前用地震资料预测地层压力、钻井过程中用随钻录井资料监测地层压力和钻井完成后用测井资料检测地层压力的方法等。对于保障钻井安全、提高钻探效率、降低钻井成本,以及及时采取对油气层的保护措施等都有十分重要的意义。本文对地层压力相关技术进行了归纳,对进行高精度地层压力预测的可行性做了进一步的阐述。更多还原

【Abstract】 There are many ways to determine the formation pressure on the stage of oil exploration,they can generally be divided into the following methods:predicting formation pressure using seismic data before drilling、monitoring formation pressure using logging-while-drilling data while drilling and examining formation pressure using logging data after drilling and so on.These methods are of great importance to the protection of drilling safety、improve drilling efficiency and reduce drilling costs,as well as the right to take timely measures to protect oil and gas reservoir.In this pa-per,some relative technologies of formation pressure are summarized, and the feasibili-ty of high-precision prediction of pore pressure was furtherelaborated.更多还原
