Multi-Sublayer Test Instrument Of The Dyinamic Parameter For The Reservoir Quality Analysis And Contrast

Multi-Sublayer Test Instrument is based on the patent of "Casing hole formationdynamics tester"，which is a new generation of cased hole wireline formation tester. Applied toTest oil of the cased hole after perforating. Or Formation Testing of oil and gas productionwells in early， middle and late. Through one trip,It can obtain formation pressure，formationpressure gradient，formation temperature and other parameters directly from the everyreservoir.Also it can provide effective formation permeability, skin factor, fluid index and thefluid density. and other important parameters. Mean while，the instrument could accuratelymeasure the gas and water interface，and complete dynamic monitoring of reservoirs. It is anintegrated oil and gas producing wells of the reservoir dynamic characteristics of the tester.This paper is based on the structure and test principle of Multi-Sublayer Test Instrument,researches the collection and transmission of instrument test data and the interpretation modelapplied to the test instrument. then focuses on Contrasting and analysising of theMulti-Sublayer Test Instrument and other obtain stratified dynamic parameters of the reservoirexisting technology. Pointes out the Multi-Sublayer Test Instrument more than others in testmethods, accuracy, and test time and economic benefits, and other aspects of the superiority.And through the oil field in the actual test to prove the superiority, and verified theMulti-Sublayer Test Instrument is feasibility and necessity. In combination with the oil fieldtest problems occurr in the process of the Multi-Sublayer Test instrument, presents theimprovement plan, for improving the development and popularization applications of goodwork in the future.
