HORIZONTAL WELL PHYSICAL MODEL AND SIMULATING TEST

To investigate the production characteristics of horizontal well in different conditions,as well as the influence of horizontal well parameters on its production rate,the physical models established abroad and their test results were classified and illustrated,focusing mainly on the three dimensional physical modeling of horizontal well.Simulating tests of horizontal wells in different conditions were carried out,and by these tests,the accuracy of horizontal well infinite flowing production rate formula in large hole diameter was proven,while the influence of borehole pressure drop on production rate was also accurately reflected.It was concluded that the three dimensional physical model is an effective way of evaluating horizontal well parameters,and it can better reflect the intercommunication of horizontal borehole with surrounding formation comparing to the theoretical method.
