摘　　要：做好碳酸盐岩储层异常高压随钻预测,是降低溢流、井漏风险发生概率的关键。针对塔里木盆地富满地区一间房-鹰山组碳酸盐岩储层异常高压预测难题,通过岩矿扫描录井技术,获取与断控缝洞型碳酸盐岩储层异常高压相关的孔隙度、裂缝数两个参数,引入反映裂缝复杂程度的裂缝复杂指数,并建立孔隙度与裂缝复杂指数图板,对塔里木盆地富满地区一间房-鹰山组碳酸盐岩储层异常高压进行识别和预测。以塔里木盆地富满地区FD 1井为例,应用孔隙度与裂缝复杂指数图板能有效表征碳酸盐岩储层异常高压段,为该地区碳酸盐岩储层异常高压研究和预测提供了一个新方法,也为下一步勘探开发提前采取工程措施,降低溢流、井漏风险发生概率提供技术支撑。Making abnormal high pressure prediction while drilling in carbonate reservoirs is the key to reduce the probability of overflow and lost circulation risks.In view of the prediction problem of abnormal high pressure in Yijianfang FormationYingshan Formation carbonate reservoirs of Fuman area,Tarim Basin,the porosity and fracture number related to abnormal high pressure in fault-controlled fracture-cavity carbonate reservoirs are obtained through rock and mineral scanning logging technology,the fracture complexity index reflecting the complexities of fractures is introduced,and the porosity and fracture complexity index chart is established to identify and predict the abnormal high pressure in Yijianfang Formation-Yingshan Formation carbonate reservoirs of Fuman area,Tarim Basin.Taking well FD 1 in Fuman area of Tarim Basin as an example,the application of porosity and fracture complexity index chart can effectively characterize abnormal high pressure sections of carbonate reservoirs,providing a new method for the study and prediction of abnormal high pressure of carbonate reservoirs in this area,and also providing technical support for further exploration and development to take engineering measures in advance to reduce the probability of overflow and lost circulation risks.
