Research On Complex Reservoir Interpretation Of Well-testing

The low permeability reservoirs in Erlian exploration area are rich in resources,but there are some characteristics such as complex lithology,various pore types and difficult to understand reservoir development characteristics.Fracturing and acidizing are the main measures for low permeability reservoir reconstruction.How to correctly judge reservoir physical properties,select measures and design measures are the important factors influencing the success of stimulation measures.In order to avoid the blindness and subjectivity of the selection of measures,it is particularly important.In order to precisely identify the reservoir and determine the effectiveness of the reconstruction measures,this paper takes the blocks of Wuliyastai and Bayindulan as examples to obtain the reservoir dynamic information by means of formation testing,the classification method of test curves is established by using evaluation and interpretation technology,and the transformation methods for different types of test curves are formed,the classification flow of transformation measures is established,and the reservoir measures are distinguished and described according to different curve classification,thus,it provides a strong technical support for the next step of oil field exploration,and meets the needs of oil field development to increase production efficiency and reserves.
