Mud logging using named shale density sensor

Shale Density meter

Operating principleMeasuring mudstone density is to monitor abnormal pressure formation. According to theregulation of mudstone compaction, the porosity of mudstone decrease in exponential functionway when the depth are increasing in normal condition, mudstone density increases with theincrease of depth. When meeting pressure transition zone and high pressure layer that wouldcause under compaction, the porosity would higher and density would lower than normalcondition. Because the density of mudstone has that change regulation, it can be measured bymudstone debris which digs from underground by designed well height. Setting normal pressureformation's mudstone density curve as base er ch are excursion form this base be seemed as pressure abnormal. The higher excursions that curve have, the higherabnormal pressure the layer gets. The start point of excursion is the peak point of transition zone.Apparatus compositionOrganic-glass cylindrical, mirror diagra fixed frame, stainless steel and top tray, floater,hammer for calm and zero knob etcSpecification Measurement Range:1-3g/cm3 Minimum sample weight: 0.05g Resolution: 0.03g/cm3
