73型找水仪用来测量油井的体积流量和含水率两个参数,计算得出分层产油量和分层产水量。在使用73型找水仪中发现,当合层流量较低时,测量的含水率值总是偏高。解释规则中曾规定,合层流量小于10方/日以下者不解释,并误认为这是油井“死水”的影响。实质上,这种现象是客观的正常反映,因为73型找水仪的测量结果不是反映含水率,而是反映持水率。油水两相滑动现象的存在导致在低流量时持水率大于含水率,
73 type water meter used to measure the volume flow and water content of the two parameters, calculate the layered production and stratified water production. The use of Type 73 water analyzer found that when the combined layer flow rate is low, the measured value of water content is always high. Explanatory rules have provided that the combined flow is less than 10 square days / day are not explained, and mistakenly believe that this is the impact of “stagnant water” in the well. In essence, this phenomenon is an objective reflection of the normal, because the measured results of Type 73 water meter does not reflect the moisture content, but reflect the water holding capacity. The existence of oil-water two-phase sliding phenomenon results in the water holding rate higher than the water content at low flow rate,
