Based on the practice of the use of φ95mm subsurface sucker rod pump in Shengtuo Oilfield in recent years, the causes of the failure of the pump are analyzed, and relevant precautions are put forward:(1)selecting oil wells with sufficient fluid supply for pumping;(2)under the condition of the pump efficiency being the same, the submergence depth of the pump being somewhat larger than that of the small pump, and 450～500m being feasible;(3)adopting Grade H ultrahigh-strength rod string and fixing a sinker bar at the bottom of the rod string;(4)selecting long stroke and low pumping speed, and more than 5m stroke and less than 6min-1 pumping speed being recommended;(5)adopting zirconium oxide valve ball and seat ＋ spray welded plunger ＋ nitrided barrel.

根据胜坨油田近几年采用φ95mm有杆抽油泵提液的实践，分析了造成这种抽油泵失效的原因，包括与其配套的脱节器失效、抽油杆断脱、泵漏、电动机不配套和生产管理不善等。为增强泵的提液能力和工作可靠性，提出5 项预防措施：(1)选择有充足供液能力的油井；(2)在保持相同泵效的情况下，泵的沉没度应略大于小泵，推荐按450～500m设计；(3)采用H级超高强度抽油杆柱，并在杆柱底部配置一定重量的加重杆；(4)采用长冲程、低冲次的参数匹配，推荐光杆冲程大于5m，冲次小于6min-1；(5)为提高泵筒、活塞和阀座的防腐耐磨性，推荐采用&氧化锆阀球和阀座+喷焊柱塞+氮化泵筒&的结构形式。

Screw pump the working principle is: screw pump work, the liquid after being inhaled into the screw pump shell and sealed by Wai space, when the initiative screw rotation, the screw pump seal volume in the squeezed increase Luoya Screw pump pressure, and along the axial movement.

螺杆泵的工作原理是：螺杆泵工作时，液体被吸入后就进入螺纹与泵壳所围的密封空间，当主动螺杆旋转时，螺杆泵密封容积在螺牙的挤压下提高螺杆泵压力，并沿轴向移动。

In the commonly used positive cycle of drilling, the mud pump is to rinse the surface with water medium ─﹑ mud or polymer washing fluid at a certain pressure, through the high-pressure hose taps and drill column ﹑ center hole in the bottom of the direct-drill in order to achieve Cooling ﹑ be cutting down the drill cuttings removal and transport to the surface purpose.

在常用的正循环钻探中﹐泥浆泵是将地表冲洗介质─清水﹑泥浆或聚合物冲洗液在一定的压力下﹐经过高压软管﹑水龙头及钻杆柱中心孔直送钻头的底端﹐以达到冷却钻头﹑将切削下来的岩屑清除并输送到地表的目的。

The ZOOMLION KSD25 Dry-Wet Horizontally directional Drill is the first drill which drills through hard rock without a bentonite and mud pump. Its pneumatic percussive technology has not only solved the problem of mud pollution, but also has increased its efficiency 40% higher than a normal drill. Additionally, its cost is also much lower, and therefore, it has been considered as a most efficient solution for complicated stratum (including pebble and gravel, backfill and rock).

中联KSD25干湿两用水平定向钻孔机是我国第一台不使用膨润土和泥浆马达就能在硬岩中钻进并导向的钻机，其国际领先的气动冲击钻机技术不但不存在泥浆污染的问题，而且效率比普通钻机提高40％以上，成本也要低廉得多，被公认为目前对付复杂地层（包括卵砾石、回填土和岩石地层）最为有效的方法。2 s# C J， k5 _% C

It is considered that fatigue crack is early produced on drill pipes, because the vibration load of drilling tools in air drilling is more severe than that in mud drilling. Fatigue cracks easily occur under alternating vibration. Because the current wellhead detecting instruments can not be used to reflect the change of pump pressure produced after drill pipe piercement timely and accurately, effective measures can not be taken in time to prevent the expansion of fatigue cracks. As a result, drill pipe fracture accidents occur.

失效分析表明，钻杆属于早期疲劳断裂，断裂主要原因是在空气钻井过程中钻具受到的震动载荷远大于钻井液钻井过程中的震动载荷，在交变的震动载荷作用下，钻具容易产生疲劳裂纹；由于现有的井口检测仪表不能精确及时反映钻杆刺穿之后产生的泵压变化，无法及时采取预防措施，疲劳裂纹不断扩展，最终导致了钻杆断裂失效。
