abbr: township;used in drilling reports.

n: Both type A and B are composed of derrick and rotary base .

a method of analysis of well behavior by matching the problem curve to curves draw from known conditions.

n: The designed ways and standard of hydraulic parameter of bit,which include the regime of the maximum jet hydraulic horse power and the maximum jet impact force etc.

n: a tropical cyclone in the western North Pacific and most of the South Pacific.

n: The ways of ordinary primary cementing,after tripping in casing ,firstly ,cleaning well by circulating drill fluid,secondly ,imputing spacer fluid and pressurizing lower plug, thirdly,imputing slurry and pressurizing up-plug,then bullheading quantitativ

n: A kind of U-shape bolt,which have thread at two end ,usually be used to chuck the wire rope.

n: a U-shaped tube. v: to cause fluids to flow in a U-tube without adding an outside force. For example, heavy mud in the drill stem will force light mud in the annulus to flow.

a fluid flow path that has a low spot. In a well, the U-tube is represented by the tubing and the annulus with the bottom of tubing as the low spot. Where two different density fluids are involved, the effect is that the lower density fluid will be pushed

n: A kind of ways be used to solve the differential pressure sticking,which use the u-tube principle to decline the fluid level of hole.

n: We can think the circular and the inner of well as the two side of u-tube.Their affection on the bottom hole must be equit.
