Evaluation of Interwell Connectivity Based on Sandbody Configuration Under the Thin Well Pattern Conditions
摘要
Abstract
The exploitation of multi-layer combined production reservoir with large irregular well spacing often con-fronts the problems,such as extreme difficulties in analysis for the connectivity of single sandbody between wells,and prominent contradiction of multiple solutions.This paper evaluates the interwell connectivity of Block X based on the classification of single sandbody configuration.According to the distribution characteristics of single sand-body,log curve shape of adjacent well,top-bottom elevation difference and occurrence characteristics of single sandbody,the static analysis is carried out to clearly divide the boundary of single sandbody.According to the com-prehensive data of tracer,suction profile and pressure test,the dynamic analysis is carried out to further clarify the water breakthrough time and the water break through rule of single channel sandbody.Based on the principle that the static and dynamic analysis results are consistent,the boundary of single sandbody is defined,and then the connectivity of different single sandbodies between wells is judged.Based on the analysis results,the paper guides the understanding of the distribution law of remaining oil in the production and proposes the measures of exploita-tion.The research shows that the measures have a remarkable impact on the yield of oil and that the accuracy of the understanding of remaining oil distribution has been improved.关键词
