Embodiment Construction

[0017] The present invention will be described below in conjunction with accompanying drawing.

[0018] as attached figure 1 Shown, main part of the present invention has: the oil amount that is placed on the ground has and size comparison sensor (fluid flow comparator), pumping unit moves to each feature point sensor (rotary position sensor), frequency converter (or compound intelligence) module), small environment temperature controller, master control CPU module, slave control CPU module.

[0019] An important part of the present invention is the frequency converter, which can be replaced by a composite intelligent module A; the main control module is an 8-bit single-chip microcomputer; the liquid flow sensor is one, and the information of the liquid flow rate and the oil yield rate can be transmitted in a timely and accurate manner For the slave control CPU module; there is one rotary position sensor, which transmits the characteristic operating status of the pumping unit...

Abstract

The invention relates to a multi-functional controller for increasing yield of oil. The said controller includes software package of expert system, liquid stream comparator, rotation position sensor, frequency converter or composite intelligent module, and CPU control module. Based on signal of oil output situtation dynamically detcted by the liquic stream comparator, the expert system analyzes and calculates oil output situation of oil pumping unit, so as to find out the static and dynamic operating points of maximum oil output. Thus, the oil pumping unit, stroke ratio etc. are adjusted to their optimal running point, making yield of oil reach maximum.

Description

technical field [0001] The invention relates to a multifunctional oil increasing control method and a controller, which are mainly applied to the intelligent oil increasing control of motors of pumping units in oil fields. Background technique [0002] Conventional pumping units currently used in oilfields generally use traditional control methods. Due to the particularity of the pumping unit’s load operation, there are several major shortcomings in use: ①The starting load is too high and the impact is large, resulting in the distribution transformer capacity and motor The selection of supporting facilities is too large. ②Due to the constant change of the recovery period of the downhole liquid level, it is necessary to adjust the number of strokes and the stroke ratio to increase production. The traditional method is to adjust the balance block of the pumping unit and replace the transmission wheel. It takes a long time to stop production for adjustment, and the accuracy of ...
