The invention discloses a compressible liquid performance test and evaluation device which comprises an experiment thimble group. The experiment thimble group comprises a first-layer thimble, the first-layer thimble is arranged in a second-layer thimble, the second-layer thimble is arranged in an outer cylinder in a sleeved mode, two ends of the first-layer thimble, two ends of the second-layer thimble and two ends of the outer cylinder are respectively connected with seal couplings, a first-layer thimble liquid inlet and a first-layer thimble liquid outlet are formed in the seal couplings at the two ends of the first-layer thimble, a second-layer thimble liquid inlet and a liquid discharging port are formed in the seal couplings at the two ends of the second-layer thimble, and a seawater inlet-outlet port is formed in the seal coupling at the upper end of the outer cylinder. The first-layer thimble liquid inlet and the first-layer thimble liquid outlet are communicated through a first high-pressure connecting pipe, a first pressurization device and a water tank are connected to the first high-pressure connecting pipe, and the second-layer thimble liquid inlet and the liquid discharging port are communicated through a second high-pressure connecting pipe. The compressible performance of different types of compressible liquid under temperature influence can be tested and evaluated by adopting the compressible liquid performance test and evaluation device.
Description
technical field [0001] The invention relates to a compressible liquid performance test and evaluation device, which is used to measure the test and test device for compressible liquid performance under simulated high temperature and high pressure conditions. It can test and evaluate the compressibility of different types of compressible liquids under the influence of temperature. Protective measures are provided for wellbore safety in oil and gas well exploitation. Background technique [0002] Due to the influence of water depth, the temperature of the seabed and shallow formations is low, while the temperature of the reservoir fluid is relatively high. In the early hours of oil and gas well testing and production, the annulus of each layer of casing will be sealed due to the flow of oil and gas in the wellbore The temperature of the fluid in the space increases significantly. As the test or production time continues, the temperature of the wellbore can rise by nearly 100 d...
