Definitions
- the increase of volume of mud in pit 9 is sensed by a conventional mud pit volume totalizer mechanism 15.
- a pneumatic mechanism such as that disclosed in US. Pat. No. 3,086,397 can be employed. This mechanism uses a float 16 that rides on the mud surface 14. This can also be done by replacing the pneumatic totalizing circuitry with electric totalizing circuits.
- the volume change measured by mechanism 15 is transmitted to a conventional and commercially available pneumatic multiplier or electric multiplier 17 by means of line 18 wherein the volume change is converted to equivalent pressure needed to compensate for the loss of mud in the well bore caused by bubble 13.
- Apparatus for controlling a well to prevent a blowout or lost circulation wherein said well contains a drill pipe and casing with an annulus therebetween and said well contains mud, and there is a mud pit communicating with the annulus, comprising in combination, means for measuring mud volume change in the mud pit, means for receiving and converting said measured volume change to a pressure change needed to compensate for the volume change according to the formula:

Claims (6)
- 2. The method according to claim 1 wherein said volume change is measured in U.S. barrels, said annular volume is measured in U.S. barrels per foot of length of the well bore, and said mud weight is expressed as pounds per square inch per foot of length of the well bore, the pressure change obtained in pounds per square inch, and the pressure in the well bore increased the amount of said pressure change if said volume change was an increase or the pressure in the well bore decreased the amount of said pressure change if said volume change was a decrease.
- 3. The method according to claim 2 wherein said mud weight is converted to pounds per square inch per foot of length of the well bore by the formula: (mud weight in pounds per U.S. gallon) X (0.052).
- 4. A method according to claim 1 where said volume change is displayed and said change of the surface pressures is made as dictated by said display.
- 5. A method according to claim 1 wherein said surface pressure change is made automatically.
- 6. Apparatus for controlling a well to prevent a blowout or lost circulation wherein said well contains a drill pipe and casing with an annulus therebetween and said well contains mud, and there is a mud pit communicating with the annulus, comprising in combination, means for measuring mud volume change in the mud pit, means for receiving and converting said measured volume change to a pressure change needed to compensate for the volume change according to the formula:
- 7. The apparatus according to claim 6 wherein said volume change measuring means is a pneumatic means which employs a float means that floats on the surface of the mud in said mud pit, said receiving and converting means is a multiplier means, and said means for changing the pressure in the well bore is a choke which controls the output of mud from the well bore.
