Abstract. The paper examines existing methods of measuring the compressibility of thixotropic media and devices to implement. Thus revealed their many shortcomings, is mainly in their low accuracy and complexity of the measurement of the unknown quantity.
In this regard, the paper gives a new way of measuring the fluid compressibility, which consists in immersing the punch down steadily at a constant rate in a vessel that is used as the bulb filled with fluid to the point until the liquid begins to rise in the annulus. And start moving cylindrical punch in the gap before the beginning of the movement thixotropic fluid (mud) called latency fluid outlet recorded stopwatch (T). further compressibility factor is determined by the fluid present a simple formula.
Keywords: Oil and gas wells, complications, mud, thixotropic liquid coaxial gap, critical shear stress, a cylindrical punch, the time lag.
