近井地带 meaning in Chinese

immediate vicinity of wellbore

The remaining oil near wellbore has been drived sufficiently after many turns of shallow pm operation , but the effect of pm decreases year by year , so the d eep pm technique must be adopted to enhance oil recovery
对于经历过多次小半径调剖治理的油田区块，近井地带的剩余油得到了充分驱替，其效果逐年下降，需采用地层深部处理措施进行深部挖潜。
In consideration of the characteristics of big pressure changes in near wellbore area of low permeability reservoirs , based on experimental result , a single well percolation mathematical model that the reservoir physical property changed with effective stress was established , equations were given for calculating the elastics and elastoplastic reservoirs under the condition of oil and water flow and an analytical equation was also given for calculating the reservoir production and bottom - hole flowing pressure
摘要针对低渗油藏近井地带压力变化幅度大的特点，以试验结果为基础，建立了考虑储居物性随地层有效应力变化的单井渗流数学模型，给出了油水两相流动下的弹性和弹塑性储层的数值解计算公式，以及弹性储层的产量和井底流压解析表达式。
