Embodiment Construction

[0055] The present invention will be further described below in conjunction with accompanying drawing.

[0056] Such as Figure 1 to Figure 3 As shown, the cement gelation instrument of the present invention includes: a temperature and pressure control system for simulating the gelation of cement slurry in downhole temperature and pressure conditions, a measurement system for measuring and recording changes in cement slurry consistency or static gel strength, and Hydraulic ejection system for measuring and recording cement wall bonding strength;

[0057] The temperature and pressure control system for simulating the gelation of cement slurry under temperature and pressure conditions in the mine includes a heating jacket 5, a thermocouple, a central controller, a slurry cup 1 for containing the slurry, a sealing piston 3, a stirring blade 4, an isolation cover 7, The pulp cup cover 2 and the booster pump 6;

[0058] The measurement system used to measure and record the change...

Abstract

The invention relates to a cement gelatinization instrument and a control method thereof. The cement gelatinization instrument comprises a slurry cup, a slurry cup cover, a sealing piston, a stirring blade, a heating sleeve, a booster pump, a torque detection mechanism and a central controller, wherein the central controller is electrically connected with the heating sleeve, the booster pump, the stirring blade and the torque detection mechanism. According to the cement gelatinization instrument and the control method thereof, the heating sleeve and the booster pump are integrated on the slurry cup, the detection of the thickening time, the static gelling strength and the compressive strength of cement can be completed at the same time, and the thickening change curve and the static gelling strength curve of the cement can be accurately monitored and recorded only by using one part of cement slurry; and the cementing strength of the cement and the casing wall is accurately measured, the cement compressive strength is calculated, the reliability is high, and use and maintenance are simple.

Description

technical field [0001] The invention relates to the technical field of cement testing equipment, in particular to a cement gelling instrument and a control method thereof. Background technique [0002] Cementing cement slurry for oil and natural gas wells is mainly used for: 1. Isolating downhole fluids from different pressure sources to prevent oil, gas and water from channeling; Purpose. [0003] If the cementing slurry thickens prematurely, the cementing pump will not have enough time to pump the cement slurry to the casing annulus, causing operation construction; if the thickening time is too long, it will take a long time for the cement to reach the specified strength. Long, waste a lot of waiting time, the high temperature and high pressure thickening instrument is a necessary instrument to simulate the solidification process of cement in the downhole environment, and to evaluate the time required for the consistency of cement to change from a flowing state to a non-f...
