Abstract
The utility model provides a sand-filled pipe with a window hole. The sand-filled pipe comprises a shield and plugs arranged at two ends of the shield; a shield body is provided with the window hole; and glass is arranged in the window hole. The sand-filled pipe has the beneficial effects that flowing forms of a displacing fluid and a displaced fluid in the sand-filled pipe can be clearly observed through the window hole in the displacement process, a flowing law and a foam form of a foam fluid in a rock core can be observed through a microscope via the window hole of the sand-filled pipe, a distribution law of the foam fluid in rock core pores is observed, and the distribution condition of remaining oil can be observed.
Description
Technical field
The utility model relates to petroleum exploration field, relates in particular to a kind of fill out sand tube of observable displacement process.
Background technology
The displacement process of observing aerated fluid under normal temperature and pressure conditions has directive significance for experiment, but for site operation, but there is no convincingness.In displacement process, need to observe flowing law and the foam form of aerated fluid in rock core, and according to the regularity of distribution of aerated fluid in the rock core hole, draw the distribution situation of remaining oil.A kind of fill out sand tube that can observe foam flowing law and foam form in rock core need to be provided.
The utility model content
The purpose of this utility model is to provide a kind of fill out sand tube that can observe foam flowing law and foam form in rock core.
According to an aspect of the present utility model, provide a kind of fill out sand tube.Comprise guard shield and be arranged at the plug at guard shield two ends, be provided with the form hole on the guard shield body, form is provided with glass in the hole.Can clearly observe displacing fluid and the nowed forming of driven liquid in fill out sand tube by the form hole in displacement process, flowing law and the foam form of aerated fluid in rock core can be observed in form hole by fill out sand tube under microscopical observation, observe the regularity of distribution of aerated fluid in the rock core hole, can be observed the distribution situation of remaining oil.
In some embodiments, guard shield is the hollow cylinder of both ends open, all is provided with the first screw thread on guard shield both ends open place inboard cover wall.
In some embodiments, plug comprises Handheld Division and connecting portion, and connecting portion is cylinder, and the connecting portion cross sectional shape is consistent with guard shield both ends open shape.
In some embodiments, be provided with the second screw thread that is complementary with the first screw thread on the connecting portion cylinder of plug.During operation, can hold and put the Handheld Division, connecting portion is stretched into guard shield inside and is connected with guard shield from the guard shield both ends open, the first screw thread matches with the second screw thread, and plug closely is connected with guard shield.
Description of drawings
Fig. 1 is the schematic diagram of fill out sand tube in the utility model one embodiment;
Fig. 2 is shield structure schematic diagram in fill out sand tube shown in Figure 1;
Fig. 3 is stopper structure schematic diagram in fill out sand tube shown in Figure 1.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail explanation.
Fig. 1 to Fig. 3 has schematically shown the fill out sand tube according to a kind of embodiment of the utility model.As shown in the figure, fill out sand tube comprises guard shield 10 and the plug 20 that is arranged at the guard shield two ends.
Two symmetrically arranged plugs 20 comprise Handheld Division 201 and connecting portion 203.Connecting portion 203 is cylinder, and connecting portion 203 cross sectional shapes are consistent with guard shield 10 both ends open shapes.Be provided with the second screw thread 205 that is complementary with the first screw thread 101 on connecting portion 203 cylinders.During operation, can hold and put Handheld Division 201, connecting portion 203 is stretched into guard shield 10 inside and is connected with guard shield from guard shield 10 both ends opens, the first screw thread 101 matches with the second screw thread 205, and plug 20 closely is connected with guard shield 10.
After enriching the glass fill out sand tube fully in experimentation, connect pipeline and just can carry out displacement test.Can clearly observe displacing fluid and the nowed forming of driven liquid in fill out sand tube by the form hole in displacement process, flowing law and the foam form of aerated fluid in rock core can be observed in form hole by fill out sand tube under microscopical observation, observe the regularity of distribution of aerated fluid in the rock core hole, can be observed the distribution situation of remaining oil.
Be to be understood that, although this manual is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of manual is only for clarity sake, those skilled in the art should make manual as a whole, technical scheme in each embodiment also can through appropriate combination, form other embodiment that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description is only illustrating for feasibility embodiment of the present utility model; they are not to limit protection domain of the present utility model, all do not break away from equivalent embodiment of the present utility model or the change all should be included in protection domain of the present utility model within.
