Log Evaluation Method for Effectiveness of Tight Oil Perforation Clusters
摘要
Abstract
Tight oil often requires large fracturing renovation to achieve production capacity.The liquid output of the selected perforation clusters is not homogeneous.Most of the perforation clusters did not reach the fracturing effect and produced low yield without effective perforation clusters.How to optimize perforating cluster becomes urgent problem.In north China,through the research on tight oil reservoir of Shulu concave,Huabei oilfield,it is found that the fracture parameters,ratio of resistivity,brittleness index,array acoustic parameters such as permeability index,and porous structure exponent have better correlation with reservoir characteristics and reservoir capacity.Based on that,we created a logging comprehensive evaluation parameter to evaluate perforating cluster effectiveness.Perforation clusters can be divided into three types,according to reservoir capacity standard,the logging evaluation index is greater than 800 for efficient perforation clusters,100~800 for effective perforation clusters and cluster is less than 100 as invalid perforation.The three types with operation parameters (fracture pressure,amount of sand,injection) and monitoring parameters (tracer flow,micro seismic monitoring crack) data,have good correlation.The evaluation of well logging parameter perforation cluster effectiveness can help us to realize optimization of perforation clusters operation.关键词
