METHOD OF OIL FORMATION DEVELOPMENT |
摘要 |
oil-producing industry, particularly, methods of development of oil formations by excitation of elastic vibrations in formations. SUBSTANCE: method includes disturbance of formation with elastic vibrations produced by motion of piston in well equipped with sucker-rod pumping unit. Connected to tubing string of sucker-rod pumping unit is liner. Piston is installed in flow string on liner and above perforation interval. Piston is moved in well fluid by deformation of tubing string of sucker-rod pumping unit by fluid weight taken up by unit plunger during its operation. EFFECT: reduced expenditures, excluded shutdowns and higher efficiency of wave effect. 2 cl, 1 dwg
