随着鄂尔多斯盆地低孔低渗地层比例持续增加,准确计算破裂压力在钻井工程、油气田开采与压裂增产工程中显得尤为重要。根据该地层特征,建立了改进黄氏破裂压力计算模型,并利用测井资料计算出模型中的各输入参数,进而计算出地层破裂压力,与压裂实测资料相对比,相对误差均在5%以内,满足各项工程需要。
With the continuous increase of the ratio of low-porosity and low-permeability strata in the Ordos Basin, accurate calculation of fracture pressure is particularly important in drilling engineering, oil and gas field exploitation and fracturing stimulation. According to the characteristics of the strata, the calculation model of improving Huang’s fracture pressure is established, and the input parameters of the model are calculated by logging data to calculate the formation fracture pressure, which is compared with the measured data of fracturing. The relative errors are all within 5% Within, to meet the needs of various projects.
