攜巖性能To ascertain how to produce differential pressure reasonably during the course of high temperature and pressure gas well testing, we must consider synthetically the following situations : both liquid in well bore and solid phase particles of mud in strata can be carried out through airflow ; we must avoid sand production out of borehole walls and make the selected differential pressure meet the demands of the testing instrument capability ; the calculation of differential pressure when no sand comes out of strata covers the calculation of strength of rock of borehole walls and airflow velocity, etc
摘要高溫高壓氣井測試中合理生產壓差的確定需要綜合考慮使氣流能夠在井筒中攜液、返排侵入地層中的泥漿固相顆粒、避免井壁出砂、滿足測試工具性能要求等；地層不出砂壓差計算還涉及到井壁巖石的強度計算、氣流流速計算等。Field using indicates that the polymer drilling fluid is suitable for the large size hole because of its remarkable cuttings removal ability ; and polysulfide drilling fluid shows its strong inhibition, anti - sloughing and good cuttings transportation ; while for polysulfide drilling fluid mixed with oil, it has better cuttings removal, suspension and lubricity, which are desirable for horizontal drilling
