目前在大庆油田,油气田开发已属于中后期油气田,对油气勘探领域都在逐渐从战区向外围扩展,而我们目前勘探开发的区块和试油的对象,大部分都是以低压、低孔、低渗为特征的非自喷井和非自喷层。因此,试油排液工作量也是逐年加大,从目前试油过程来看,排液是其中施工周期最长、工作量最大、影响资料上交的一道重要工序,也是制约提高试油效率的重要因素之一,排液质量的好坏直接影响试油结论和对储层的准确认识。本文全面介绍目前大庆油田常用的试油排液工艺技术的适用范围、基本工作原理及优缺点等,并举例说明这几种排液方式在大庆油田的应用,同时结合生产实践经验提出一般情况下勘探试油排液选择的意见。 At present, in Daqing Oilfield, the development of oil and gas fields has belonged to the mid-late oil and gas fields, and both are gradually expanding from the theater to the periphery in the field of oil and gas exploration. Most of the objects we are currently exploring and developing are oilfields with low pressure, Non-self-spraying wells characterized by low permeability and non-self-spraying layers. Therefore, the workload of test oil drainage is also increased year by year, from the current test process, drainage is one of the longest construction cycle, the workload of the most important, affecting the data submitted an important process, but also to restrict the test to improve the efficiency of the oil One of the important factors, the quality of liquid discharge directly affects the conclusion of oil testing and accurate understanding of the reservoir. This paper introduces the applicable range, basic working principle, advantages and disadvantages of the test oil drainage technology currently used in Daqing Oilfield and gives an example to illustrate the application of these drainage methods in Daqing Oilfield. At the same time, combining with the practical experience of production, Exploration of oil discharge liquid choice advice.
