Description

Oil gas well cementing operation grout volume variable quantity is measured device
Technical field
The utility model relates to a kind of measurement mechanism, particularly a kind of measurement mechanism of oil gas well cementing operation grout volume variable quantity.
Background technology
In the oil gas well cementing operation engineering, the performance of grout is the principal element of decision well cementation success or failure and cementing quality quality.Cementing slurry volume in hydration process can change, and produces physics and chemical shrinkage usually.The cement stone of oil gas casing and borehole wall annular space shrinks and makes cementation interface produce the gap, and water breakthrough and has channeling take place, and influences cementing quality, shortens the oil well life-span, reduces the oil gas production yield rate.Simultaneously, some oil well cement swelling agents that occur on the market lack the method and the instrument of accurate testing product expansion character, can't judge the true and false quality of product.Therefore, new material research staff, oil and gas development engineering design constructor are badly in need of understanding the volume change characteristic of grout, need a kind of convenient instrument that detects the grout volume variable quantity.
Summary of the invention
Goal of the invention: the purpose of this utility model provide a kind of continuously, accurately, be convenient for measuring the device of oil gas well cementing operation grout volume variable quantity.
Technical scheme: oil gas well cementing operation grout volume variable quantity described in the utility model is measured device, it is characterized in that it is made of heating part and measure portion, heating part comprises heating element, insulation cylindrical shell, inner bag and automatic temperature measurement and control element, and heating element places between insulation cylindrical shell and the inner bag; Measure portion comprises the container that is full of media fluid that places in the inner bag, cover lid at container finish, be inserted in the band scale glass tube on the lid, and places in the container and fill the sample plasma bottle of cement prize.
Described sample plasma bottle is the bottle that resilient material is made.
Described media fluid has the media fluid of higher boiling, low volatilization, low thermal expansion characteristic.
Principle of the present utility model: heating part provides the curing temperature condition for the cementing slurry sample, and measure portion has accurately measures the volume change of cementing slurry sample in maintenance processes continuously.The grout sample is filled in elasticity heatproof sample plasma bottle, and the sample plasma bottle external form is shunk, expanded with grout volume fully.Fill the sample plasma bottle of grout and put into the container of filling media fluid, the liquid level change amount of media fluid is volume change.
Beneficial effect: the utility model can provide down-hole circulating temperature curing condition, and the volume change of continuous coverage grout, Applicable temperature scope-30-250 ℃.The measuring accuracy height, it is convenient to measure.Apparatus structure is easy simultaneously, expense is cheap, can generally be applicable to occasions such as cementing slurry preparation, new material development, product quality inspection.
