Research And Application Of Paraffin Removal Supporting Technology In Liaohe Oilfield

In this paper,the mechanism of paraffin,paraffin hazard is studied,on all major Paraffin removal techniques are compared,especially for Xing Gu Qianshan block in high gas oil ratio,high oil well casings and Ollie Shengtuo oilfield high Paraffin oil well paraffin removal technology is studied in detail,the various the Qing were classified and adaptability of Paraffin prevention technology.By means of chemical paraffin removal technology,hollow rod flushing device,pipe test technology of Paraffin in oil field and practical application of heating and electricity,according to the characteristics of the oilfield,the modified Paraffin removal technique,wherein the hollow rod flushing device obtained national patent.The paraffin is affected by many factors,mainly crude oil itself,the Paraffin content,temperature,pressure,dissolved gas,asphaltene,mechanical impurities,water,lift etc..The Paraffin content of crude oil is high,easy to Paraffin;low temperature,low pressure,degassing seriously;,is easy to Paraffin;asphaltene and mechanical impurities in high,is easy to form the Paraffin crystal nucleus,easily deposited;high water content,is not easy to Paraffin;produced fluid temperature is high,is not easy to separate out the Paraffin.In the actual production,the oil field,a growing variety of Paraffin removal technique can be applied.The main mechanical paraffin removal,thermal paraffin,surface energy(liner and coating tubing),ultrasonic paraffin,magnetic paraffin,microorganism Paraffin removal,chemical paraffin removal technology.In this paper,according to the characteristics of oilfield proposed Paraffin supporting technology,some oil wells using only a paraffin removal technology can not satisfy the production demand,the needs of a variety of Paraffin removal technology combination.
