No counterweight digital intelligent oil extraction unit

Abstract

The invention discloses a non-counterweight digital intelligent oil (gas) pump. The non-counterweight digital intelligent oil (gas) pump comprises a stand, wherein a machine body is mounted on the stand; a power driving device is mounted at the inner side of the bottom of the machine body; a telescopic transition wheel bracket assembly is mounted at the top end of the machine body, and is wound with a traction steel wire rope; and one end of the traction steel wire rope is connected with an oil pumping rod polish rod, and the other end is in transmission connection with the power driving device through a load reducing movement pulley assembly. The power system is arranged at the bottom end in the machine body, so that the characteristics of safety, environmental protection and random adjustment (1-5 m) of stroke length are achieved. Moreover, a counterweight device is omitted, so that the raw material is saved, the cost is reduced, and the most important is that a series of troubles and unsafe factors of installation, maintenance and operation caused by the counterweight device are thoroughly solved.

Description

technical field [0001] The invention relates to an oil pumping machine, in particular to a counterweight-free digital intelligent oil pumping machine, which belongs to the technical field of oil and gas exploitation equipment. Background technique [0002] The largest oil production consumption in the field of domestic and foreign oil extraction is the oil extraction equipment - pumping unit. Only one item of oil production equipment (pumping unit) accounts for more than 60% of the entire oil mine production expenditure. [0003] At present, the main equipment used in oil fields at home and abroad is the beam pumping unit, such as figure 1 , figure 2 As shown, the front end of the beam 2 is provided with a donkey head 3 and is close to the wellhead 1, and the rear end of the beam 2 is connected with a counterweight 5, which is connected with the motor 6 and the reducer 4. The pumping unit is still from the 1950s The old-fashioned American equipment has complex structure,...

Problems solved by technology

[0015] The problem to be solved by the present invention is to overcome the above-mentioned defects of traditional pumping units and provide a digital intelligent pumping unit without counterweight, which completely breaks the structure that all pumping units in the history of the world’s pumping units have counterweight devices Features, using the principle of four-two dials, combined with advanced and reliable digital intelligent control, the counterweight device is removed, which not only saves raw materials and reduces costs, but more importantly, completely solves the installation, maintenance, operation, etc. caused by the counterweight device. A series of troubles and insecurities
