双封隔器MDT在单井产量预测中的运用

近年来，经过Schlumberger公司改进的地层动态测试器双封隔器模块（双封隔器MDT），已在四川盆地部分孔隙度低于10%、渗透率10×１０^３μｍ^２以下的储层和高含硫气藏中获取了准确的地层压力，所进行的地层流体性质判别具有独到之处，对及时发现油气层、减少试油层位、缩短勘探周期、降低勘探成本起到了一定的作用。在川东黄龙场构造飞仙关组致密低孔低渗气层中，该测试器顺利完成压力测试，并根据压力测试结果做出了合理的单井产量预测，这是利用双封隔器MDT进行减少试油层位、缩短试油周期的成功经验，值得大力推广。

APPLICATION OF DUAL PACKER MDT TO FORECASTING THE PRODUCTION OF SINGLE WELL

In recent years, the dual packer module of MDT improved by Schlumberger Co. is of originality in the aspects of acquiring accurate formation pressure and distinguishing formation fluid property in the reservoir with porosity below 10％ and permeability＜10×103 μm2 in Sichuan Basin, and plays a certain role in the respects of timely discovering oil and gas formation, reducing oil gas production test layer, shortening exploration period and cutting down exploration cost. In the low porosity and permeability gas reservoir of Huanglongchang structure Feixianguan Formation in east Sichuang Basin, pressure testing is smoothly completed with the tester and based on the pressure testing result, the single well production is reasonably forecasted, which is successful experience being worth vigorously spreading in the respects of further reducing oil gas production test layer and shortening exploration period with dual packer MDT.
