Working Load (KN) YJZ hydraulic-mechanical drilling jar integrates hydraulic principle with mechanical principle, it s a new type drilling jar, which can suit for all kinds of drilling operations, and go with drilling tools assembly to descend the well when used. The drilling tools are often sticked due to many kinds of reasons in down hole when in normal drilling operations, and this type drilling jar is an effective tool for releasing stuck. When the drilling tools are sticked, it can make drilling jar generate upward or downward jarring force through lifting and landing the drill strings, so it can release resistance and the stick by many time jarring, and recover normal drilling operation promptly. Meanwhile avoid resistance and stick to become further accident, and cause larger economic losses. If releasing force is failed, it can dynamiclly adjust at anytime on sites and be easy to use. Max.

34 CEMENTING TOOLS AND CASING ACCESSORIES Float Shoe, Float Collar & Cementing Plug Float shoe: when landing the casing, the drill fluid have no resistance to float shoes. The pressure of circulating mud make the valve head down a displacement, the disc of valve rod s end will fall off automatically; after stop pumping,the valve press the valve seat upwards under the action of spring, the float valve becomes one-way valve. So that can pump the drilling fluid and cement slurry into it from up to down, but the fluid in the casing or outside casing annulus cant t be return to prevent from back flow. float Collar: the using metthod is the same as float shoes except the lower end is pin. It is connected with casing. The usage of float collar is to make the casing landing easily by reducing the loading. When landing the casing, make sure to prevent from the drill fluid flow into the casing. After cementing, the float collar can prevent the cement slurry retuming to the casing. Cementing Plug: when the drilling fluid make the bottom plug move into the end, raised plum flower petal of the bottom plug s lower end engaging with the hollow plum flower petal of float collar s upper end. At the same time, the pressure rise, when reach the definite pressure, the burst disk in the bottom plup crush, the passageway open, and the pump pressure descent, at this time can cementing. After cementing, pumping into th top plug to clean cement slurry on the inner wall, the raised plum flower petal of the top plug engaging with the hollow plum flower petal of the bottom plug.
