存在有限导流断层的条带状油藏试井新模型
Well-testing Interpretation Model for Strip Reservoirs with Finite Diversion Faults
摘要
Abstract
At present,well fault seal analysis tests are mainly focused on closed faults.When using the existing well test interpretation model to explain oil and gas well-test data with non-closed faults,especially with a finite diversion fault boundary,the results are not ideal.By introducing the concept of interfacial skin,a new model of well-test interpretation with a finite diversion fault in stripe reservoirs was established.The model considers not only the fluid passing through the fault plane,but also the flow of fluid in the fault.The Fourier cosine transform,Laplace transform,and other mathematical physics methods were used to obtain the bottom hole pressure equation.The bottom hole stress response curves of the model were plotted,and there were seven flow stages.The results show that the larger the FCD value,the more concave the curve.The larger the S value,the more convex the curve;when the S value is sufficiently large,characteristics of a closed fault are demonstrated.ηfD mainly affects the amount of decrease in the pressure derivative curve.The fluidity ratio,thickness ratio,and pressure derivative coefficient ratio mainly affect the increase and decrease in the pressure derivative curve.关键词
