... share of lowyield oil deposits with low-permeability reservoirs increases among the newly introduced fi ds. Such deposits, as a rule, are exploited with low bottomhole pressures in wells and worsened performance of pumping equipment due to the infl e of free gas. Reduction of the negative eff of free gas on the pump is achieved in various ways in each case. One of the optimal methods is the use of shanks with elongated intake fi ers. The paper describes a number of other technological and technical methods ...

... photoelectron emission medium developed a techniquefor measuring the quality and quantity of transported oil. Results It were revealed main factors affecting the results of measuring the quality and quantity of oil. The need for continuous measurement of free gas is confirmed. Measurement technique based on radioisotope radiation and main results of laboratory tests are described. Сonclusions 1. Radioisotope method is very effective and provides a measuring of free gas in oil flow, which has a great ...
