Inclined Well Test Analysis Theory And Its Characteristics

As the technology of slant well has becoming matured.more and more inclined well are used for the exploitation of submarine reservoir.Also the application of declined well to onshore oil field has becoming increasingly widespreaded.The main purpose of the slant wells is to take full advantage of offshore platforms,marine mining through land.avert barriers on land.Although inclined wells have been widely used in common practise,but the research of technology for inclined well testing is not enough.Usually,we adjust data of inclined wells to the process of vertical wells which will not meet the needs of practical application. According to the comments above.we have to take a further research about the theory and technology of inclined well testingIn this paper.from PDE of the basic point source of homogeneous infinite space,we established PDEs of the basic point source to homogeneous infinit formation.By application of mirror image theory and other methods,we can obtained basic source solutions of those PDEs.By integrating those solutions along the well path.we can derivate formulas of pressure response.Using Stehefst’s inversion of laplace transform and Duhamel’s principle.we can get type curves of slanted well by programing and analyze influential factors of transfusion.The main research domains are as follows:1)By establishing and solving transfusion PDEs of reservoir with both impermeable ends or both constent pressure ends or mixed ends.we can get pressure response of inclined well by integrating the solution along well path.Then by programming,we can get types curves and analyze influential factors.2)By esiablishing and solving transfusion PDE of reservoir with both impermeable ends and circle impermeable or constant pressure bound,we can get response formula by integrating the solution along well path.Then by programming.we can get types curves and analyze influential factors.3)By application of mirror image theory,we can get solutions of PDE to reservoirs with both impermeable ends combining one fault or perpendicular angle faults.Then we can get pressure response of inclined well by integrating the solution along well path.And by programming.we can get types curves and analyze influential factors.4)Sovling solutions of the all those models in double porose reservoir,we can get type curves and analyze influential factors through the same way.
