Description
Technical field
The present invention relates to oil-gas exploration and development field, more particularly to a kind of sandpack column pipe.
Background technology
In the recovery ratio experiment of petroleum industry, when carrying out Physical Experiment in microbial oil displacement room, back-up sand is typically used for
Model pipe.When being tested, it is necessary to along journey and outlet production fluid detection and analysis and pressure monitoring, carry out residual along journey in model pipe
When excess oil saturation distribution rule and the Adsorption law of quartz sand, it is desirable to accurately get in model pipe along Cheng Hanyou stratum water
With the quartz sand sample of residual oil.
When the recovery test of in general sandpack column pipe petroleum industry, due to sandpack column pipe air-tightness and
It is larger that the sampling inaccuracy of detection result in result of the test error.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of sandpack column pipe, more accurately can get in model pipe
Along Cheng Hanyou stratum water and the quartz sand sample of residual oil, and air-tightness is stronger.
In order to solve the above technical problems, the technical scheme is that：A kind of sandpack column pipe, the sandpack column pipe bag
Include：Body, blind flange, flange；Body is hollow tube, and pressure test port and specimen port are provided with the side wall of body, body
It is provided at both ends with flange；Blind flange is located at the both ends of body, is connected between blind flange and flange by screw；Its innovative point exists
In：It is provided with one raised on blind flange, is provided with groove on flange, the projection on blind flange is embedded in the groove of flange, flange
A packing ring is provided between the groove in projection and flange covered.
Further, filter and screen pack are provided between the blind flange and flange；Told screen pack was arranged on
On filter plate, filter is screwed on the inwall of blind flange by screw, and filter is located in the convex inner walls of blind flange with screen pack.
Further, axis direction is provided with runner and ring pressure mouth, blind flange and body conducting on the blind flange.
Further, the aperture of the pressure test port is 1mm.
Further, the hollow tube of the body can be that section can be square.
Further, the roughness of the hollow inside pipe wall of the body is more than Ra12.
Further, the pressure test port and specimen port are provided with screen pack.
The advantage of the invention is that：
1）The roughness of the body hollow tube of the sandpack column pipe is more than Ra12, can prevent experimentation sand grains and inwall it
Between leap up flow phenomenon；
2）Hollow tube can be section can be it is circular or square, can effectively in simulation displacement process pressure field effectively point
Cloth, the distribution of pressure field on especially same section, and on same section chemical agent distribution situation；
3）Entrance, outlet, pressure tap, sample tap and each connecting portion of the sandpack column pipe are equipped with metal filter screen,
Preventing the quartz sand outflow of inside influences experimental conditions；
4）The end of the sandpack column pipe is cooperated by the projection set between blind flange and flange with groove, then passes through pad
Circle is sealed, and ensures that good sealing effectiveness.
