摘要
测试二开抽汲二关井长时钟小探边工艺,通过抽汲诱喷油层,改善井周渗流条件和降低油层污染程度,获得油层的真实产能。使用长时钟(192h)可较长时间开关井,取得井筒较远处油藏动态信息,及时对油藏开展早期评价,为勘探开发提供决策依据。
This paper tested the small limit test techniques of long timepiece of the second well startup swabbing and the second shut-in well . By swabbing and inducing flow from the petroleum reservoir, it may be ameliorated flow condition around the well,and reduced contamination degree of oil formation, as a result, acquired the real deliverability of reservoir. In this study, the long timepiece (192 h) applied can start and close well for long time and can acquire the dynamic reservoir information from faraway wellbore. Therefore, the techniques can evaluate reservoir in time, and can provide decision base for the exploration.
