| Low-permeability oil and gas ifelds discovered in China account for more than half innewly discovered reservoirs,and have become the main battleifeld of oil and gas developmentand construction.With the General water injection,as oil properties are different in layers andinterlayers is very conspicuous,The sudden of single layer and the tongue phenomenon isvery apparent in the water injection process, which result in uniformly longitudinal launchingof water.Therefore,for this type of reservoir,precise water injection is very necessary.The study take Jingbian Oilifeld for example,combined the reservoir engineering withreservoir physics,mechanics,sedimentology and other disciplines,Based on the Geologicalmodeling and simulation,Make design for the injection wells and choose the appropiratetools. At the same time by the way of pulling the testing instrument to test the injection profileand form. And get the Related parameters which lay the foundation for injection in fiiture.Thefield expeirment has achieved remarkable results that not only solve the single dash but alsoimprove production. |
