| Extend the wells exemption of the technical requirements under the new North oil field,analysis of the various factors that affect the oilfield exemption period,which,the most influential factors that oilfield sand depth analysis.The new North Oilfield sand production mechanism in-depth study,a clear understanding of the characteristics and laws of the new North sand;through the wellbore fluid carrying capacity study obtained under various conditions of liquid sand-carrying ability,scientific and effective measures to take sand a reliable basis.Combined results,take the low-yielding serious sand well to chemical sand-based application grit pump,grit the drain,dual Seoul where anti-slag,sand tubes,supplemented by the program of measures for the new North well a small amount of sand,and take the pump on to mention hanging with the use of two pump plus grit tail pipe measures,the sand volume stripper wells to take the chemical sand used in conjunction with the sand pipe,grit pumps,grit,oil spills,pairs where the Seoul anti-slag and other down hole sand control device,data and explore the law for all the sand out of the sand wells according to the routine testing influence diagram and the previous job site to develop a reasonable flushing cycle the pump on a regular basis to propose a work cylinder large displacement flushing through these types of clear sand control measures,the effect of clear sand has greatly improved,thus extending the exemption of oil wells to achieve the purpose of increasing production and saving operating costs.New North oil field oil well maintenance operations had significantly fewer single well exemption periods to the end of 2011 the 590d,and achieved good results by taking effective clear sand countermeasures,since 2008.Basically solved plagued the development of a new northern oilfields contradictions,the new North Oilfield next step to achieve high yield,stable and reduce development costs as possible. |
