Extended Chaheji Oilfield Pump Inspection Cycle Form A Complete Set Technology Research And Application

As Chaheji oilfield development entered the later period,water cut rising rate of climb.Reservoir at the same time the scale of production gradually expand,geology and oil well is becoming more and more different complex conditions,Chaheji huzhuangji oilfield in recent years of rod pumping wells tube problem,cause the pump inspection work frequently,and how to identify the influencing factors of oil well pump inspection cycle,oil becomes the main technical personnel in the face of new challenges.This article through to Chaheji collection factors affecting oilfield pump inspection cycle and the optimal design model is the basis of research,to the stress of the sucker rod pipe calculation model analysis,thus influence on the pump inspection cycle factors have a clear understanding of the mechanism,in order to achieve prolong pump inspection cycle,combined with the daily work of this paper,the research accumulation and the design of rod string is optimized,according to the principle of equal stress range first calculate and determine the proportion of all levels of rod string,to the combination of conventional model calculated according to the actual situation of the oil Wells well conditions and history homework revised,to form a more adaptive Chaheji set oilfield optimization design.At the same time analyzed the sensitivity of the factors influencing factors of pump inspection cycle.In rod tube through the application of the supporting technology,management work,according to the track the eccentric wear of pump inspection well site records,analysis of eccentric wear factors,combined with the rod string optimal design,taking "deviation,the anchorage rod + centralizer,high water cut,the eccentric wear collar,unreasonable submergence-damping rod + adjustable parameter" preventing eccentric wear matching process,such as the "a well a policy of" targeted governance,strengthening production management measures.At the scene to guide to carry out the homework at the same time,and strengthen the supervision over the quality of well under the rod tube,effectively reduce the rod eccentric wear problem.Calculation and analysis of the impact of parameters of pumping unit well,the preparation of the well data in the best state.Through the use of information data collection after the corresponding matching to each wells and diagrams were analyzed,and various parameters in time parameters and anomaly change of indicator diagrams,the accident hidden trouble in advance before the intervention,to reduce the number of pump inspection,and summing up experience and extension of pump overhaul period.
