Thisisdonebypumpingaslurry offracgelandproppantthroughaheatedshearlooptoconditionthefluidand simulatedownholeconditions. The slurryisthenpumpedthoughaseriesof pipestomeasuretheshearstressexhibitedbytheslurryatdifferentshearrates. Usingthisshearstressvs.shearratedatatherheologicalpropertiesoftheslurry canbedetermined(n ,k ,apparentviscosity). Followingthepiperheometerthe slurryisflowedthroughaslotrheometerwheretheproppanttransportcanbe visualized. Bycomparingtherheologicalpropertiesof theslurrywiththeactual proppanttransportobservedtheusercanhaveabetterunderstandingofthe proppanttransportoffluidsonlocationwhenitisimpossibletovisualizetheactual proppanttransport. Studiescanbeconductedtodeterminetheoptimumfluid propertiesthatwillmaximizeproppanttransportbutminimizeformationdamage. Inaddition,thesettlingpropertiesoftheproppantinvarioustypesoffracgelcan alsobeinvestigated. 北京富瑞兴达科技有限公司 北京市朝阳区慧忠北里新荣家园C座3G号 100012 ChaoyangDistrict,Beijing,Huizhongbeili,XinrongHome,BlockC3G100012 T:010-64466834 F:010-64466834-603 E-mail:horsewell.hk@163.net www.horsewell.com.cnPage2of13 6/26/2008 2.Specifications a.PressureratingwithSlotRheometer: 30psi b.PressureRatingbypassingSlotRheometer:150psi c.TemperatureRating:150F d.FlowRateRating:maximumpumpingrateof2,500ml/min e.Targetperformancespecificationswillbedemonstratedinan acceptancetestduringthetrainingthatwillbeconductedatStim- Lab.
