摘要
用P-T封隔器、剪销封隔器进行跨隔测试时,测试压力曲线在初关井期间曾发生过前期或后期压力恢复上升速度异常现象,以往均解释为地层原因,经过对测试和监测压力曲线进行综合分析,并对跨隔测试管柱P-T封隔器进行井下受力分析及结合井筒条件,解释了产生异常压力曲线的原因。提出了避免异常压力曲线的相关工艺措施。
Abnormal phenomena of ascent speed for build up pressure at fore or latter testi ng period is happened to testing pressure curve at firstly closing well when using P-T packer, shearpin type of packer to conduct straddle test and the reason for these are due to formation reason for interpretation. By comprehensive analysis for testing and monitoring pressure curve and stress at down hole for P-T packer of straddle testing stem and combining with bore hole condition, the reason of abnormal phenomena is interpreted and some measures and techniques are proposed to avoid them.
