抽油井智能分层测试技术研究

On Intelligent Zonation Testing Technology for Pumping Well.

油井出砂、井况复杂及开发后期高水淹的影响,现有抽油井分层测试技术难以取得齐全有效的产液剖面资料。提出了常规产液剖面和广义产液剖面的概念,介绍利用一套智能分层测试组合管柱,配合地面测试,可以完整地录取油井分层产量、含水、分层压力、流体性质及储层参数的变化等资料。通过孤东10-13井的测试实例,介绍抽油井智能分层测试技术的应用及效果。

It is very difficult to acquire all-round and effective data of production profile from existing zonation testing approaches for pumping wells because of sand inflow, complex well conditions and severe water flooding during late development period. Two concepts are put out, i. e. , conventional production profile logging and generalized production profile logging. A set of combination of pipe string is introduced which is used in intelligent zonation testing and can acquire full data of each zone oil output, water content, zonal pressure, liquid property, variations of reservoir parameters in combination with surface testing. The example of well Gudong 10-13 shows up the better application effect of this intelligent zonation testing technique.
