A kind of screen casing horizontal well production profile testing arrangement.Enter difficulty, testing expense is high, construction risk is large deficiency in order under the instrument that the horizontal well production profile measuring technology overcoming existing sieve tube completion exists, the utility model releasing device I, releasing device II, releasing device III are fixedly connected sequentially by screen casing; Tracer is separately installed with in releasing device I, releasing device II, releasing device III; In completion practice, device is mounted in completion tubular column, the interlayer of releasing device I between toe payzone and middle part payzone, the interlayer of releasing device II between middle part payzone and heel payzone, releasing device III is positioned at the interlayer at heel payzone rear portion, carries out completion construction operation; After operation, use gamma spectra checkout equipment to carry out gamma-ray spectrum analysis to Produced Liquid on ground, the Species and characteristics content passing through seized tracer analyzes production profile.Its beneficial effect achieves without wireline test, and construction safety, risk are low, decreases job execution expense. |
