认为在影响欠平衡钻井的钻井液静液柱压力、环空压耗、欠压值、井口回压、地层压力中，地层压力是首先要搞清楚的最基础的压力，最好先求出地层压力而不必急于进行欠平衡钻进，因为一切欠平衡的压力计算都是建立在这个基础压力之上的；再根据地层压力确定合理的欠压值，确定所用的钻井液密度。

When entering the diaphragm pressure on the top of the control room to the atmosphere or water by the downstream area of low pressure, the role of the bottom plate in the valve and the pressure below the diaphragm on the pressure value is greater than the top, so the main valve disc to the fully open position; when entering the diaphragm pressure above the control room can not water the lower reaches of the atmosphere or area of low pressure, the role of the diaphragm on the top of the pressure value is greater than the pressure below the value, so will the main valve pressure valve set to fully closed position; when the diaphragm pressure above the value of the control room at the entrance of the middle pressure and outlet pressure, the main valve in the regulator valve on the disk, and its regulation depends on the location of the needle-catheter system and adjustable valve guide of the role of joint control.

当阀门进入隔膜上方控制室内的压力水被排到大气或下游低压区时，作用在阀盘底部和隔膜下方的压力值就大于上方的压力值，所以将主阀阀盘推到完全开启的位置；当进入隔膜上方控制室内的压力水不能排到大气或下游低压区时，作用在隔膜上方的压力值就大于下方的压力值，所以就会把主阀阀盘压到完全关闭的位置；当隔膜上方控制室内的压力值处于入口压力与出口压力中间时，主阀阀盘就处于调节状态，其调节位置取决于导管系统中的针阀和可调导阀的联合控制作用。

Bellows Gate Valves However, in large differential pressure operating conditions, evaporation pressure has eased, the evaporator load requirements of the fluid volume decreased, but the actual situation the contrary, in the suction superheat unchanged, due to evaporation pressure has eased, the evaporator outlet pressure be reduced accordingly, pressure changes above and below the diaphragm, causing the main valve opening increases for increased fluid; but in a small pressure operating conditions, evaporation pressure rise, evaporator load demand for fluid volume increased, but the reality is that in the suction gas superheat unchanged, due to evaporation pressure rise, a corresponding increase in the evaporator outlet pressure, pressure difference above and below the diaphragm smaller, so that the main valve opening decreased for the reduction of liquid volume; in variable load is all about.
