Research Progress and Development Tendency of Transient Well Testing Technology
In order to better monitor the production performance of oil and gas reservoirs and improve the production capacity of oil and gas fields,this paper reviews the principles,interpretation methods,and application effects of four commonly used transient well testing technologies.It analyzes the problems existing in transient well testing technology and proposes future key research directions.The results show that the currently commonly used transient well testing technologies mainly suffer from serious inter-well interference,complex characteristics of testing curves,low accuracy of testing interpretation,and low efficiency and high losses in conventional testing of complex fault block reservoirs.While new types of testing technologies such as numerical well testing,vertical interference testing,and low-frequency pulse testing can address these issues.The future development trends of transient well testing technology lie in deep and ultra-deep testing processes,evaluation of low-permeability tight reservoir testing data,assessment of fracturing effects,and integrated application of data.Emphasis can be placed on technical breakthroughs in numerical well testing and multi-layer testing.Through a comprehensive analysis of transient well testing technology,this study can provide technical references for on-site testing and offer new perspectives for sub-sequent technological developments.
