method and apparatus for testing the potential influence of the poroque blocking flow in porous media, the water content of the nonrenforces - permeability clay

摘要

according to the invention, in order to determination degree of sensitivity to water - permeable porous media degree prevention of anti blockage in a first stage,a flow path is established for a reference to aromatic liquidtime obtained at a set flow quantity which was stationed in the aromatic 24h after previously dislodged solution of nacl in 12% of stationary sample in turn 24h and 'cursessample flow is through until it stabilizes.then in a second stage proceed to establish a flow time of the same kind of aromatic after sample was dislocated with fresh water which flowed in the first stage, aromatic,fresh water which aramas challenge for 24h, and then flowed through the sample until the flow was stabilized, being dislocuita then with aromatic,whose flow time was measured in the second stage.setting time is performed at the same respective flow conditions of difference pressure flow and the same amounts of aromatic, which is recorded by the challengeand the flow solutiilor and hydrocarbons in the two stages, is maintained until the stabilisation - respectively till two-stroke consecutive flow - be equaland the flow out time for aromatic in the two stages of the sensitivity of the sample.and for getting a degree to prevent negative influence of fresh water. after...
