| titleOfInvention | Simulation test device and method for high-temperature water-wet curing of cement stone of thermal production well |
| abstract | The invention discloses a high-temperature and wet-curing simulation test device and method for cement stones in a thermal production well. The device mainly comprises a nitrogen source 1, a middle water container 5 and CO 2 Air supply 10, flowmeter 12, airtight cauldron body A13, manometer 17, condenser 19, heating furnace 22 constitute, place set cement 24 in the airtight cauldron body A13, be located heating furnace 22, cauldron body A side lower part has the water inlet, and flowmeter 12 and heating pressure manifold 11 are connected respectively to this water inlet, heating pressure manifold 11 had both connected water container 5 in the middle of, nitrogen gas source 1, still connects CO 2 A gas source 10; the upper part of the side end A of the kettle body is provided with a water outlet which is connected with a pressure gauge 17 and a condenser 19 and can be used for simulating a maintenance method that the cement stone of the thermal production well is corroded by acid media at different temperatures. The closed kettle body A13 is replaced by the closed kettle body B25, and the closed kettle can be used for testing the shear cementation strength and channeling pressure of the cement stone in a high-temperature water-wet environment. The invention has reliable principle, simple operation and wide market prospect. |
