井温测试资料在油井热洗作业中的应用

用综合井温测试资料评价热洗井方法,并以此方法跟踪抽油机热洗全过程,获得井筒内温度随深度的变化情况和热洗过程中井筒内不同深度的温度随热洗时间的变化情况。再结合大庆油田萨中地区结蜡规律对测试结果进行综合解释,确定该油田抽油机井的热洗强度。利用井温测井资料指导油井热洗清蜡作业,明显地降低了作业施工的能源消耗。

Application of Temperature Log Test Data in Thermal Washing Operation of Oil Well

The method of evaluating thermal washing oil well with comprehensive temperature log test data, tracing whole process of thermal washing with pumping unit with this way can obtain the variety of well bore temperature with the variety of depth and the change of temperature at different depth of the thermal washing process with thermal washing time. Combining with wax deposit regulation of Sazhong segion in Daqing oilfield to comprehensively interpret the test result, the thermal washing intention of pumping unit well in the oilfield is determined. That utilizing temperature log data to instruct thermal washing and paraffin removal operation in oil welt reduces the energy consumption obviously.
