DEVICE FOR SIZING BOREHOLE GEOPHYSICAL EQUIPMENT

摘要

FIELD: oil and gas production.;SUBSTANCE: in device for calibration of well-logging geo-physical apparatus of neutron logging loose material contains additional fraction in form of solid elements of water containing substance uniformly distributed in volume of case. The elements of water containing substance correspond to crumbs out of waste of secondary polymers of high and low pressure or to polyethylene granules uniformly distributed in medium of marble crumbles (MC) and quartz sand (QS). Volume ratio of shares of MC, granules and QS is chosen from: C_p=1-V_marb-V_s; V_marb+V_s+V_gr=(1-K_o); K_g=(1-V_gr)/K_p; 0V_marbK_o; 0V_s(1-V_marb)·K_o, where: K_o=0.6 is constant coefficient characterising volume fraction of porous space at one-fraction loose filling, K_p is coefficient of porosity, K_g is coefficient of gas saturation, V_marb, V_gr and V_s are volume fractions of marble crumbs, polyethylene granules quartz sand correspondingly.;EFFECT: upgraded accuracy of calibration of well-logging geo-physical apparatus of neutron logging used in gas saturated reservoirs.;3 cl, 3 dwg
