In the previous article, we mentioned the problems of sucker rod pump valve cover disconnection, pump failure, and valve leakage. Combined with the years of work experience of our technicians, we give specific suggestions. Let's take a look!
1. Sucker rod pump valve cover disconnection failure response:
For the sucker rod pump valve cover disconnection failure, technicians and maintenance personnel need to pay full attention to it. Combined with the actual situation of oil field exploitation, the relevant standards and specifications should be strictly implemented to determine the scientific torque value. At the same time, when selecting the material for the valve cover, corrosion resistance and durability should be considered, and stainless steel 3CR13-4CR13 materials should be preferred. In the process of cleaning the thread, in order to avoid corrosion problems, a special cleaning agent should be used, and then anaerobic glue should be applied for bonding. During the operation, the staff must adjust the anti-impact distance according to the specific model and parameters of the sucker rod pump to avoid frequent collisions. In addition, through the above operations, the tensile strength and corrosion resistance of the oil pump valve cover can be improved, the probability of valve cover disconnection failure can be reduced, and the operation effect of the sucker rod pump can be guaranteed with advanced construction technology.
2. Dealing with sucker rod pump stuck pump failure:
For the response to the stuck pump failure, it is also necessary to combine the actual situation. First, make a reasonable selection and control of the matching clearance to reduce the occurrence of the stuck pump problem from the source; second, the corresponding process measures should be improved to reduce or even avoid the entry of silt and pipe scale into the pump barrel; third, the water injection quality should be further improved to reduce the problem of scaling in the pump: fourth, the anti-stroke distance should be reasonably adjusted to prevent the stuck pump problem caused by scaling. In addition, in the process of dealing with the stuck pump failure, it is also necessary to consider the alternating stress of the reciprocating motion link of the sucker rod pump plunger, and set the corresponding centralizer on the sucker rod to ensure that the downward inertial force coincides with the gravity of the sucker rod itself and the pump axis. On the other hand, avoid the generation of torque to ensure that there will be no alternating large stress on the floating valve cover, which helps to extend the service life.
3. Dealing with the valve leakage of sucker rod pump:
For the treatment of valve leakage of sucker rod pump, first, improve its wear resistance and fatigue resistance, and strengthen its anti-injection ability; second, improve the construction quality standard to reduce the damage of sucker rod pump valve cover, so that the valve ball of sucker rod pump can be opened normally. With the help of advanced technical means, the valve can achieve the effect of no puncture and no leakage.
