Abstract
The effective sand bodies in the Sulige area are in a strip shape.The lateral distribution of single-phase isolated sand bodies is mostly 300 to 500 meters,and the width-to-thickness ratio of the sandy braided river sand bodies is between 40 and 100.Based on the dynamic analysis of gas wells in the block,combined with dynamic test data such as gas field interfer-ence well testing and pressure build-up well testing,this paper evaluates the effective control range of gas wells,determines the scale of controlled sand bodies,analyzes the inter-well connectivity,screens the dynamic constraints for fine reservoir modeling,and analyzes their distribution patterns.The results show that the effective width of a single sand body in the M14 well area is less than 600 meters,the scale of isolated or superimposed but unconnected effective sand bodies is 300 to 500 meters,and the scale of superimposed and connected effective sand bodies is 500 to 1 600 meters.The width-to-thickness ratio of the effective sand bodies is close to that of the sand bodies.In high-permeability areas,the probability of connectivity of superimposed sand bodies is relatively high,with a sand body scale of 500 to 1 600 meters.In low-permeability areas,superimposed sand bodies are either unconnected or isolated,with a sand body scale of less than 300 meters.关键词
