镇泾油田红河105井DST测试资料解释与评价

DST Data Interpretation and Evaluation for Well Honghe105 in Zhenjing Oilfield

镇泾油田红河105井长8油层是该油田第一口DST测试能够自喷的油井,由于设计的二开井为48 h,而开井仅流动19.66 h油流就达到井口形成了井口关井的情况,虽可采用常规的试井解释方法对井口关井恢复段的压力进行参数解释,但失去了二关井作用并浪费了时间。本文介绍了红河105井地层测试设计、施工及关井资料解释处理方法并提出今后该区地层测试时应注意的问题和建议。

Well Honghe 105(Layer Chang-8) in Zhenjing Oilfield is the first natural flowing well in DST.The duration of the second flow was 48 hours according to the design,but the oil reached wellhead and the well was shut in automatically when the flow lasted only 19.66 hours.Although the conventional well test interpretation method can be used to analyze the pressure build up data,yet the meaning of the second flow is lost and the test time is wasted.This paper introduces the design,operation and the interpretation method for the second build up data of the DST for Well Honghe105,and gives some proposals and what should be paid attention to during DST in future in this field.
