1、浅谈不加热冷输集输技术的应用Introductiontonotheatingcoldgatheringtechnologyapplication所谓冷输即掺常温水不加热集油，是在转油站自放水温度连续稳定在350C左右，计量间掺水压力高于1.4MPa，单井回压不高于0.6MPa的状况下，可采用掺常温水不加热集油方式，可停运站内全部加热炉。So-calledcoldthatmixingwateratroomtemperatureheatingoil,andisinturnstationsincethecontinuousstableatabout350cwatertemperatu

3、。便于消费管理，我们把冲洗干线周期定在7天以上，推算出41%的油井（33口）可继续冷输观查，24%的井（19口）冷输时从消费管理上思索根本上放弃了冷输。Backpressurerise.Fromthenormalconsumptionof80Wellsspotcheckintosee,accordingtochangeofproductionvalueandcurrent(inhydraulicarrivedat0.8MPatostopoil),oilpressurewashingmainarrivedat0.60MPa.Facilitateconsumptionmanagem

5、范围内，以保证整个系统的掺水压力。例如西21-S504井产液100t，含水87.0%，该井四天内油压由0.35MPa上升到1.15MPa，液量由100t降落到72t，从产液和含水剖析该井压力不应上升这样快，从该井与状况相近的西2-丙02井（油压14天由0.32MPa上升到0.88MPa，液量由101t降落到95t）比照，该井处于低洼地带，低洼地带里水把干线吞没，春季温度低，形成的油压上升较快。Environmentalfactorsrestrictthecoldtolose.Abnormalsituationintheprocessofcoldloseaboutrenderin
