Apparatus and methods for continuous compatibility testing of subterranean fluids and their compositions under wellbore conditions |
摘要 |
Disclosed is a fluid testing device which utilizes a small, cross-section fluid interface to separate a test fluid chamber from a drive and measuring chamber. The test fluid chamber contains the test fluid and a paddle-type fluid test assembly. The drive and measuring chamber contains a second fluid and assemblies for moving the paddle and for determining the resistance movement. The two chambers are connected together by a narrow cross-section passageway allowing for continuous testing while test fluids are flowed through the test chamber and for successive testing of different samples without breaking down the device between tests. A pair of coaxial shafts extends between the test fluid chamber and the drive and measuring chamber. The shafts are connected together by a spring located in the drive chamber whereby the resistance to movement is determined by measuring the deflection in the spring. The shafts are magnetically coupled to a motor to rotate the shafts.
