Dynamie Test Information Explanation And Applieation Model Investigation In Multiwell Rescrvoir

Dynamic test information has always played an important role in oil field development.Dynamic test information usually includes pressure data,temperature data,the production dataand fluid property PVT data,etc. But now the dynamic test information applications in thereservoir are limited to the single wells.Dynamic test information in multiwell reservoir hasnot been sufficiently used.The method that we use multiwell reservoir dynamic testinformation to analyze interwell connectivity is accurate and valid to get results and hassufficiently used dynamic test information in multiwell reservoir.This method has manyadvantages: simplicity and convenience,accuracy and low cost.This paper introduces the common dynamic test information types and analysis methodsfirstly,including production logging analysis method,the well test analysis method andproduction data analysis method;and elaborates the traditional interwell connectivity methodthe advantages and disadvantages of various methods.This paper focus on the use of dynamic test information in multiwell reservoir to analyseinterwell connectivity between injection-production patterns;and states the interwellconnectivity multivariate linear regression model and interwell connectivity capacitance modeland analyse the fluid signal time lag and attenuation rules. In the course of the study, themethod of numerical simulation is to verify the correctness of multivariate linear regressionmodel and capacitance model.This paper finally uses capacitance model to analyse the interwell connectivity in a lowpermeable oil fields block and points out the influence on the oil fields.The results show thatthe use of dynamic test information in multiwell reservoir to analyse interwell connectivity toget good effect.The method is simple and more feasible.
