集流型井下流量计的改进设想

Improved Imagine for Down Hole Low-Concentrating Flowmeter.

为完成对油田高、中、低产液油井的测试,避免由于井筒流体在集流器外形成“集流压差”和“上推力”,使集流型井下流量计测量上限受到限制,提出一支集流型井下流量计在油井中起下一井次,完成对不同产液量油层的测试设想方案,将全集流和部分集流的井下流量计合二为一, 使得任何一支流量计都有全集流和部分集流的特点。新设想集流型井下流量计具有测量下限低、测试范围广、自动分流、测点稳定等特点。

For completing the test of wells with high, medium and low production, avoiding from flow-concentrating pressure difference and up push appeared at collector of bore hole fluid to produce a confine for the upper measuring limitation of down hole flow-concentrating flowmeter. The paper suggests a plan that using one down hole flow-concentrating flowmeter down and up once time in the oil well to finish test for different produced layers and integrate full and part down hole flow-concentrating flowmeter to make every flow-meter have feature of full and part flow-concentrating. The new flowmeter has the characteristics of low floor level, extensive testing scope, automatic distributary and stable testing point.
