摘　　要：酸化、压裂等措施是油气井增产的重要手段,不稳定压力试井是评价改造效果的主要手段之一。针对塔里木油田库车山前低孔低渗透率裂缝性砂岩高压气井缺少措施改造后试井测试数据的情况,提出先对措施改造前测试数据进行精细试井解释,获得基本的渗透率、表皮系数、地层原始压力、无阻流量等参数;然后使用措施后的井口生产数据与井口压力数据,利用井筒模型将井口压力折算为井底压力,结合措施改造前精细试井解释获得的相关参数,获得措施改造后的表皮系数、无阻流量等结果,对改造效果进行定量化评价。大量实践表明,此方法结果准确,对该区措施井的效果评价具有良好的适用性。Acidification,fracturing and other measures are important means to increase production of oil and gas wells,and the unstable pressure testing is one of the main means to evaluate the effectiveness of the transformation. According to the Kuche Piedmont of Tarim oilfield with low porosity and low permeability fractured sandstone in high pressure gas well after the transformation measures lack of well test data,the fine interpretation of test data is given before the transformation measures to obtain the basic permeability,skin factor,original formation pressure,flow parameters; and then using the transformed wellhead data and the wellhead pressure data,the wellhead pressure converted into bottom-hole pressure by the wellbore model,and combining with related parameters obtained from well testing interpretation before the transformation measures to get the results of skin factor,open flow capacity that interpret quantitatively the transformation results. A lot of practice shows that this method is accurate,and it has good applicability in the evaluation of the effectiveness of the measures in this area.
