摘要
随着油气田开发的不断深入,地层压力的不断下降,大多油田已进入渗透率低、高含水阶段。当前油田为了增产普遍采用压裂手段来构造具有高导流能力的填砂裂缝,改善油气井储层的渗流能力、泄油面积从而提升油井的产油量。现场采用偏心电位法对某井进行压裂测试研究,通过对压裂过程中地表测点电位数据收集与处理,带入模型反演来达到对裂缝参数的预测。该技术可应用于油田的压裂场测试以及裂缝各参数的预测与评判,其对压裂作用效果的评估具有重要的工程应用价值。
With the continuous development of oil and gas fields,and the formation pressure has been continuously reduced,the most oil fields had entered the stage of low permeability and high water content.In order to increase the output of oil volume in oilfields,fracturing methods are generally used to construct sand-filled fractures with high diversion capacity,so as to improve the seepage capacity,discharge area of oil and gas well reservoirs,that increase the oil production of oil wells.In this paper,the eccentric potential method is applied to perform a fracturing test and study the well on the spot.It is the collection and processing of surface measurement point potential data during the fracturing process that should be brought into the model inversion to complete the predictions of crack parameters.This technology can be used for fracturing field testing and for forecasting and evaluating the effect of fracture parameters in oilfields,which has important engineering application value.
