摘要
塔里木盆地富满地区碳酸盐岩缝洞型油藏产能预测分析多是定性认识,且产能预测方程可操作性较差。通过分析稳定渗流压裂井产量与井底压力关系,发现影响各井产能的主要因素是生产压差和裂缝发育程度。根据钻井期间目的层钻具放空和泥浆漏失量情况将富满地区试油井分为3类,同时分别统计分析3类井生产压差和日产油、日产气的关系,最终形成了1套符合富满地区断控缝洞型油藏的产能预测方法。利用该方法对富满地区7口试油井进行产量预测,有5口井试油后验证产量误差在15%以内,符合率达到71.43%。该方法使用简单、可靠性强,可在塔里木盆地富满地区推广应用。
The productivity forecasting of fractured-vuggy carbonate reservoirs in the Fuman area of the Tarim Basin is often qualitative,and the productivity equations are less operable.By analyzing the relationship between production and bottomhole pressure for the fractured wells with a stable flow,it is found that the main factors affecting the productivity of each well are production pressure difference and fracture development degree.Based on drilling break and mud loss in the target layers during drilling,the testing wells in the Fuman area were classified into three categories.The relationships between production pressure difference and daily oil/gas production for the three categories of wells were statistically analyzed.Finally,a productivity forecasting method for fault-controlled fractured-vuggy reservoirs in the Fuman area was developed.Using this method,the production of seven wells in the Fuman area was forecasted.It is indicated that the production error of five wells after testing was within 15%,with a coincidence rate of 71.43%.The simple and reliable method can be widely applied in the Fuman area of the Tarim Basin.
