摘要:
葡萄沟地区葡10井区七克台组Q1砂组砂层薄,横向变化快,非均质性强,常规波阻抗难以区分砂泥岩,制约了该区的开发进程。通过“地震波形指示马尔科夫链蒙特卡洛随机模拟(SMCMC)”算法,将地震、地质和测井信息有效结合,通过测井曲线标准化、敏感参数分析、储层精细标定、地质模型建立、似然函数及目标函数计算等重要环节,实现了葡10井区七克台组Q1砂组2 m以上薄砂层的预测,反演结果与已知钻井匹配程度较高,后验井吻合率达85%,为开发井位部署提供了强有力的技术支撑,并以此部署多口钻探井位,取得良好的钻探效果。
Abstract:
In Q1 sand group of Qiketai Formation of P10 well in Putaogou area, there is thin reservoir, a rapid lateral variation, strong heterogeneity, and weak distinguishing ability of normal wave impedance. So the development process is hindered in this area. Using the algorithm including seismic waveform indication of Markov Chain and stochastic simulation of Monte Carlo(SMCMC), the information of seism, geology and logging can be effectively combined. By the means of standardization of logging curves, analysis of sensitive parameters, fine calibration of reservoir, geology modeling, and calculation of likelihood and objective functions, it was carried out the prediction of thin reservoir above 2 m of Q1 of Qiketai Formation. The inversion result is in good agreement with drilling, with a predication accuracy of 85%. Thus the predicated results can provide the technique support to the well deployment, with a good drilling effect.
