To meet the demand of higher built-up rate ,single-bending screw drill tool with large angle is used during the drilling of the moderate-and short-radius horizontal well.

钻中短半径水平井，在采用弯角较大的单弯螺杆钻具以满足高造斜率的需要时，由于套管内径较小，螺杆钻具钻头处位移比较大，螺杆钻具能否顺利通过直井段是钻中短半径水平井面临的一个重要问题。

Therefore, the pump body with the outer surface of screw and screw and screw more space should be as small as possible.

因此，泵体与螺杆外圆表面及螺杆与螺杆间隙应尽可能小些。

Single-Screw Pumps is an enclosed screw pump with inner gearing, a kind of rotor positive-displacement pump. As this kind of pump is characterized by being adaptable for the medium, stable flow, good suction performance and small pressure pulsation, it can transfer very viscous media or those containing hard suspended or solid grains or fiber apart from various flowing media. Besides, it boasts good adjusting performance, wide range and high efficiency. Therefore it is widely applied in various industries like environmental protection, shipping, petroleum, pharmacy, household chemical, food, brewage, construction, mining, chemistry, printing, paper making, power plants and boilers.
