随钻地层孔隙压力预测技术，是在钻进过程中利用随钻地层孔隙压力监测结果，对钻前的地震预测模型和结果进行修正，并根据新修正的模型，对钻头下部未钻开地层的孔隙压力进行再预测，以此来提高地层孔隙压力的预测精度。在塔西南琼002井进行了现场试验。首先收集了该开区的地震层速度资料，并进行地层压力预测处理。施工过程中，利用dc指数法和岩石强度法进行地层压力随钻监测。钻至3500m时，根据监测结呆对地震预测模型进行反演修正，根据修正结果进行了再一次修正。经钻后证实，新预测的结果平均误差为12％，比原预测结果平均误差30％减少了18个百分点，致使琼002井钻井作业顺利，并提前完钻。
The technology of pore-pressure-while-drilling prediction is to correct the pre-drilling earthquake prediction model and result by using the pore-pressure monitoring of formation-while-drilling formation during the drilling process. According to the newly revised model, Pore pressure re-forecast, in order to improve the prediction accuracy of pore pressure. Field test was conducted in Well 002, Southwest Tasian. The seismic velocity data of the open area are collected first, and the formation pressure prediction is processed. During the construction, the stratigraphic pressure is monitored while drilling by the dc index method and the rock strength method. Drilling to 3500m, according to the monitoring of the stay of the earthquake prediction model inversion correction, according to the revised results were once again amended. After drilling confirmed that the new forecast results of the average error of 12%, 30% lower than the original forecast average error of 18%, resulting in drilling well 002 Well Joan well drilling in advance.
