摘要
为了进一步增加特低渗透油藏的经济效益,降低成本,根据吉林油田油藏特低渗透率、低含油饱和度、低孔隙度、低温、低压、浅层低产等特点,对石油压裂增产措施进行分析,找出了与吉林油田地质特点相符合的低温压裂施工参数和程序。大量的室内和现场试验表明,复合压裂技术为最佳增产工艺。通过2010~2014年进行的500多井次的试油压裂,成功率达99.4%。
In order to further increase the economic benefits of low permeability reservoirs,reduce the cost,and according to reservoir features of low permeability,low oil saturation,poor porosity,low temperature,low pressure,shallow buried layer and low yield in the Jilin oilfield,the fracturing stimulation for oil has been analyzed,and the low temperature fracturing operation parameters and procedures being consistent with Jilin oilfield geological characteristics are found out.A large number of indoor and field test show that the composite fracturing technology is the best one to increase production.Through more than 500 Wells of oil test and fracturing operations during 2010 ~ 2014,the success rate reaches to 99.4%.
