| description | FIELD: oil industry, well completion and running to raise their productivity and oil recovery from pools. ^ SUBSTANCE: equipment includes cylindrical body of pump which lower butt part is plugged and has inlet holes in upper part, sludge collector in lower part, two plungers, as minimum, mounted in body for reciprocating motion and formation of vacuumed space under them. Plungers are interjoined by means of stiff member. Plungers have same diameter but different lengths. Upper plunger has smaller length than pump under inlet holes. Length of stiff member is equal to sum of lengths of plungers and travel of plunger located beneath that is determined by time of filling of vacuumed space with well fluid. Lower part of body is placed below level of inlet holes over length of plunger with smallest length. It has inner diameter larger than inner diameter of upper part of body. At least three longitudinal guides are uniformly spaced in it along cylindrical element of body. They come in the form of flat ribs. Inner diameter of circle inscribed in them equals diameter of plunger. ^ EFFECT: increased operational efficiency of equipment owing to possibility of adjustment of amplitude and frequency of hydraulic action on critical area of formation. ^ 3 cl, 2 dwg |
