Abstract
A training apparatus by which situations liable to occur during drilling for oil and gas, such as a blow out, may be simulated to teach better control thereof. The apparatus comprises a miniature drilling rig, a transparent bore hole casing imitation and a pressurized oil/gas reservoir imitation sealed from the casing by an easily through-drilled plug in the lower end of the casing.
Claims9
An apparatus for teaching pressure control in drilling for oil and gas, comprising
- a complete miniature drilling rig,
- a drilling pipe connected at one end thereof with said drilling rig,
- a drilling bit connected with the other end of said drilling pipe,
- a casing and a reservoir,
- said reservoir including a container filled with particulate material and being provided with means for controlling the supply of pressurized gas,
- said casing including a transparent tube communicating with said reservoir through a screen,
- a plug replaceably located in the lower part of said casing and adapted to be penetrated by said drilling bit when said drilling pipe is lowered from said miniature drilling rig, whereby the gas pressure in said reservoir is transmitted to said casing, and
- a miniature blow out preventer stack located in the upper part of said casing.
