高含水油井含水数据误差分析及对策

范庄油田已处于高含水、特高含水开采阶段,油井产出液含水率波动大,无规律,由于受现场操作方法、环境条件、设备等因素的影响,化验的原油含水数据的真实性和有效性降低,数据不能准确反映油井当前含水状况,增加了原油生产的计量误差,进而影响油田开发方案的制定和实施。文章以范庄油田高含水油井为研究对象,针对原油取样、含水化验整个过程,分析造成含水数据出现误差的节点及原因,制定针对性措施,提高了油井含水化验数据的准确性。

With the further production of reservoir,Fanzhuang oil field has developed into a stage with high water cut,even extra high water cut. Besides,the proportion of water occupied in the overall produced liquid fluctuates swiftly without a regular law. Due to the effects of field operation method,environmental condition and equipment status,the data reality and validity of tested oil decreases correspondingly,which can not reflect the present water cut of a producing well. On the other hand,measurement errors caused by those effects increase during the process of oil production,which have a great influence on the formulation and implementation of the field development program. Taking the Fanzhuang oil field as an example,this paper focuses on the whole process of crude oil sampling and testing,analyzing the moment when the data error appeares and the reason which causes it. Based on the above work,effective measures have been put forward,which improve the accuracy of the testing data.
