Abstract
The utility model discloses a drawing board used for obtaining water flooding degree, which mainly solves the problem that a great deal of paper is wasted caused by that no simple tool is used for complete the drawing board evaluation by using effective drainage porosity and remaining oil saturation evaluation. The drawing board is characterized in that a box type support body is covered by a transparent drawing board which is provided with a coordinate system with the effective drainage porosity of the horizontal axis and the remaining oil saturation of the vertical axis; the coordinate system is provided with at least three divisional locating strips; in the box type support body, the middle part of a vertical frame is fixed with a transverse limiting body and a longitudinal limiting body which are respectively provided with grooves on the same plane; and the side opposite to the transverse limiting body is the testing paper entrance which is on the same plane with the grooves of the transverse limiting body and the longitudinal limiting body. The drawing board can be used in specific stratum areas with unlimited times after first division, and has the characteristics of accurate locating and saving paper.
Description
Technical field:
The utility model relates to the aid that the oil reservoir logging field is used to estimate the water logging of stratum degree, and a kind of specifically and well log interpretation data combine makes the chart board that is used for estimating the water logging of stratum degree.
Background technology:
Oil displacement efficiency is to estimate a kind of method for quantitatively evaluating of oil reservoir washing degree, but it has certain limitation in production application.Because oil saturation changes after the reservoir water flooding, initial oil saturation is the empirical value of a theory or mathematic statistics, though and remaining oil saturation is through a series of correction, but error is objective reality always, therefore, rely on the oil displacement efficiency quantitative assessment will cause the erroneous judgement of part layer fully.In fact, the reservoir water flooding situation is very complicated, microcosmic and macroscopical fingering phenomenon of injection water often occur, actual producing water ratio and oil displacement efficiency always do not have positive correlation preferably, in this case only according to the difficult accurately judgement of oil displacement efficiency reservoir water flooding situation.In order to remedy the deficiency of oil displacement efficiency quantitative assessment, the technician has created the plate evaluation method of effecive porosity and remaining oil saturation evaluation, but when using this method, often need to consume a large amount of paper and make plate, use this method and lack a kind of simple tools, this is real to be deficiency of the prior art.
The utility model content:
In order to solve in the prior art, when using the plate evaluation method of effecive porosity and remaining oil saturation evaluation, no simple tools is finished, cause a large amount of paper to be expended the problem of falling, the utility model provides the chart board that is used to ask for water flooding degree in a kind of plate evaluation method that can be applied in effecive porosity and remaining oil saturation evaluation, this kind chart board through can be unlimited behind the subzone location specifically use the characteristics that have easy to use, accurate positioning and save paper in the layer region at one.
The technical solution of the utility model is: this kind is used to ask for the chart board of water flooding degree, comprise the boxlike supporter, described boxlike supporter, on be coated with a transparent chart board, it is effecive porosity that a transverse axis is arranged on this transparent chart board, the longitudinal axis is the coordinate system of remaining oil saturation, at least three root partition positioning strips are arranged on this coordinate system, in the described boxlike supporter, be fixed with a cross spacing body and two longitudinal spacing bodies at the middle part of stile, wherein, have the groove that is on the same horizontal plane separately on described cross spacing body and the longitudinal spacing body, with the offside of cross spacing body then be the test paper inlet, this inlet also is on the same horizontal plane with groove on cross spacing body and the longitudinal spacing body.
The utlity model has following beneficial effect: to have transverse axis be effecive porosity owing to there is one on this chart board that is used to ask for water flooding degree, the longitudinal axis is the transparent chart board of the coordinate system of remaining oil saturation, can utilize acquired well log interpretation data earlier, according to the statistics rule, on this transparent chart board, utilize the subregion positioning strip to determine good not washing, weak washing, middle washing and strong washing zone, then when the plate evaluation method of practical application effecive porosity and remaining oil saturation evaluation, the test paper of determining good concrete effecive porosity and remaining oil saturation coordinate is inserted in this chart board, and the present position of this block just comes into plain view so.Think in view of the above, if use this chart board, so through can be unlimited behind the subzone location specifically use the characteristics that have easy to use, accurate positioning and save paper in the layer region at one.

Fig. 1 is a transparent drawing plated construction schematic diagram of the present utility model.
Fig. 2 is the structure sectional view of boxlike supporter in the utility model.
Fig. 3 is a use schematic diagram of the present utility model.
Fig. 4 carries out the schematic diagram that subregion is located before being to use the utility model.
The transparent chart board of 1-among the figure, 2-subregion positioning strip, 3-cross spacing body, 4-stile, 5-longitudinal spacing body, 6-test paper inlet, 7-boxlike supporter, 8-anchor point, 9-test paper.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2, shown in Figure 3, this kind is used to ask for the chart board of water flooding degree, comprise boxlike supporter 7, on described boxlike supporter 7, be coated with a transparent chart board 1, it is effecive porosity that a transverse axis is arranged on this transparent chart board 1, the longitudinal axis is the coordinate system of remaining oil saturation, at least three root partition positioning strips 2 are arranged on this coordinate system, in the described boxlike supporter 7, be fixed with a cross spacing body 3 and two longitudinal spacing bodies 5 at the middle part of stile 4, wherein, have the groove that is on the same horizontal plane separately on described cross spacing body 3 and the longitudinal spacing body 5, with the offside of cross spacing body 3 then be test paper inlet 6, this inlet also is on the same horizontal plane with groove on cross spacing body 3 and the longitudinal spacing body 5.During use, can utilize acquired well log interpretation data earlier, as shown in Figure 4,, on this transparent chart board, utilize the subregion positioning strip to determine good not washing, weak washing, middle washing and strong washing zone according to the statistics rule.When the plate evaluation method of practical application effecive porosity and remaining oil saturation evaluation, the test paper of determining good concrete effecive porosity and remaining oil saturation coordinate is inserted in this chart board then, the residing position of this block just comes into plain view so.For not using this chart board, improved operating efficiency, and saved paper greatly.And use this chart board, so can be unlimited after through location, a subzone specifically use in the layer region at one.In addition,, can adopt bonding method to be fixed on the transparent chart board 1 described subregion positioning strip 2 so, can move with the need if consider and in other subterranean formation zones, to use.This chart board has been applied in the zones of different.
