Abstract
The utility model relates to a stable type hydraulic piston pump capable of conveniently entering a well and lifting. The stable type hydraulic piston pump comprises a ground power fluid container, a ground plunger pump, a control manifold, a well head control valve and a downhole pump. The ground power fluid container is connected with the ground plunger pump through a pipeline, the ground plunger pump is connected with the control manifold through a pipeline, and the ground power fluid container and the control manifold are connected with the well head control valve and the downhole pump respectively through pipelines. Four upper hydraulic cylinders are evenly distributed on the upper end of the outer wall of the downhole pump, and four lower hydraulic cylinders are evenly distributed at the lower end of the outer wall of the downhole pump. The four upper hydraulic cylinders at the upper end of the outer wall of the downhole pump correspond to the four lower hydraulic cylinders at the lower end of the outer wall of the downhole pump one to one. Supporting universal wheels are evenly distributed and fixedly arranged on the outer wall of the downhole pump located between the upper hydraulic cylinders and the lower hydraulic cylinders. The stable type hydraulic piston pump is simple in structure, scientific and reasonable in design, simple in manufacturing, low in cost, and capable of effectively improving downhole pump work stability and well entering efficiency.
Description
Technical field
The utility model belongs to hydraulic piston pump field, and especially a kind of being convenient to promotes stable type hydraulic piston pump into well.
Background technique
Hydraulic piston pump to high gas-oil ratio (HGOR), shake out, high solidifying oil, the content of wax, viscous crude, deep-well, inclined shaft and horizontal well have stronger adaptability.Hydraulic piston pump mainly comprises that Surface power drive flow container, plunger pump, control manifold, wellhead control valve and underwell pump form.Underwell pump is the core component of this system, and underwell pump easily rocks unstable collision tube wall when work, affects oil recovery efficiency, when entering well, easily rocks and touches well casing, has reduced and has entered well efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of being convenient to promote stable type hydraulic piston pump into well, this hydraulic piston pump is simple in structure, design science reasonable, it is simple to make, cost is lower, effective has improved underwell pump working stability and has entered well efficiency.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of being convenient to promotes stable type hydraulic piston pump into well, comprise Surface power drive flow container, ground plunger pump, control manifold, wellhead control valve and underwell pump, Surface power drive flow container connects ground plunger pump by pipeline, ground plunger pump connects control manifold by pipeline, Surface power drive flow container is connected wellhead control valve and underwell pump by pipeline respectively with control manifold, it is uniform four upper end oil hydraulic cylinders in underwell pump outer wall upper end, at uniform four the lower end oil hydraulic cylinders of underwell pump outer wall lower end difference, four upper end oil hydraulic cylinders in underwell pump outer wall upper end are corresponding one by one with four lower end oil hydraulic cylinders in underwell pump outer wall lower end, the uniform support universal wheels that is fixed with on the underwell pump outer wall between upper end oil hydraulic cylinder and lower end oil hydraulic cylinder.
And, on described underwell pump outer wall, be fixedly mounted with two groups and support universal wheels, 4 every group are supported universal wheels uniform being packed on underwell pump outer wall respectively.
Advantage of the present utility model and beneficial effect are:
Originally be convenient to promote stable type hydraulic piston pump into well, comprise Surface power drive flow container, ground plunger pump, control manifold, wellhead control valve and underwell pump, Surface power drive flow container connects ground plunger pump by pipeline, ground plunger pump connects control manifold by pipeline, Surface power drive flow container is connected wellhead control valve and underwell pump by pipeline respectively with control manifold, it is uniform four upper end oil hydraulic cylinders in underwell pump outer wall upper end, at uniform four the lower end oil hydraulic cylinders of underwell pump outer wall lower end difference, four upper end oil hydraulic cylinders in underwell pump outer wall upper end are corresponding one by one with four lower end oil hydraulic cylinders in underwell pump outer wall lower end, the uniform support universal wheels that is fixed with on the underwell pump outer wall between upper end oil hydraulic cylinder and lower end oil hydraulic cylinder, the utility model is simple in structure, design science is reasonable, make simple, cost is lower, effectively improve underwell pump working stability and entered well efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of being convenient to promotes stable type hydraulic piston pump into well, comprise Surface power drive flow container 1, ground plunger pump 2, control manifold 9, wellhead control valve 3 and underwell pump 4, Surface power drive flow container connects ground plunger pump by pipeline, ground plunger pump connects control manifold by pipeline, Surface power drive flow container is connected wellhead control valve and underwell pump by pipeline respectively with control manifold, it is uniform four upper end oil hydraulic cylinders 5 in underwell pump outer wall upper end, at uniform four the lower end oil hydraulic cylinders 8 of underwell pump outer wall lower end difference, four upper end oil hydraulic cylinders in underwell pump outer wall upper end are corresponding one by one with four lower end oil hydraulic cylinders in underwell pump outer wall lower end, the uniform support universal wheels that is fixed with on the underwell pump outer wall between upper end oil hydraulic cylinder and lower end oil hydraulic cylinder, on underwell pump outer wall, be fixedly mounted with two group 6, 7 support universal wheels, every group 4 are supported universal wheels uniform being packed on underwell pump outer wall respectively.
If the when work vibration of the utility model underwell pump is large or mounting structure unstable after, four upper end oil hydraulic cylinders, four lower end oil hydraulic cylinders can be withstood to well tubular wall, to increase stability, in the time of in entering pipe well, support universal wheels and effectively prevent underwell pump collision pipe well inwall, cause damage.
