Fig. 2 is a kind of well selecting device structural representation based on oil well measure provided in an embodiment of the present invention.
Specific embodiment
With reference to embodiment in detail the application is described in detail, but the application is not limited to these embodiments.
Embodiment 1
Referring to Fig. 1, a kind of well choosing method based on oil well measure is embodiments provided, the method includes：
101st, the geological information of the first oil well is obtained；
In the embodiment of the present invention, can obtain in real time can also periodically or non-periodically obtain the geological information of the first oil well,
The present invention is not specifically limited to this.
In the embodiment of the present invention, geological information includes the affiliated block of the first oil well, straticulate exploration of the first oil well, first oily
One or more in the information such as well sandstone effective thickness.The distribution situation of remaining oil is mainly judged in geological information,
In geologic development, identical block has same or like ground layer lineage, and straticulate exploration is that oil mass is more in ground layer lineage
Or the easy series of strata of exploitation.The embodiment of the present invention is not restricted to specific geological information, in actual applications, can basis
Demand is chosen.
Sandstone effective thickness can regard the storage location of oil as, the bigger explanation of sandstone effective thickness this penetrate the storage of layers apart position
Oil is more, is typically only recovered the oil in the big sandstone position perforation of effective thickness.
Whether the geological information for the 102nd, judging first oil well meets the first predetermined threshold value, if it is, execution step 103；
Show in the geological information of the first oil well the block a certain series of strata contain Fuel Oil Remaining be worth exploitation when, it is determined that should
The geological information of the first oil well meets the first predetermined threshold value.In the embodiment of the present invention, the first predetermined threshold value includes n preset value, n
For the species of geological information, that is to say, that a preset value is correspondingly arranged for each geological information, when each geological information
When meeting its correspondence preset value, it is believed that the geological information of first oil well meets the first predetermined threshold value.
103rd, the production information of the first oil well is obtained；
In the embodiment of the present invention, production information includes daily fluid production rate, daily oil production, water content, stream pressure, hydrodynamic face, sinking
One kind or many in the information such as degree, strata pressure, recoverable reserves, cumulative oil production, recovery percent of reserves, remaining moveable oil storage capacity
Kind.The embodiment of the present invention is not restricted to specific production information number, in actual applications, can choose according to demand.
Whether the production information for the 104th, judging first oil well meets the second predetermined threshold value, if it is, execution step 105；
105th, the first oil well is elected as and treats abandoned wells and upper measure.
In the embodiment of the present invention, the second predetermined threshold value includes m preset value, and m is the species of production information.That is it is
Each production information is correspondingly arranged a preset value, when each production information meets its correspondence preset value, it is believed that should
The production information of the first oil well meets the second predetermined threshold value.
For example, the corresponding preset value of the sandstone effective thickness of the first oil well is a1, and the corresponding preset value of daily fluid production rate is a2,
It is a5, hydrodynamic face that the corresponding preset value of daily oil production is a3, the corresponding preset value of water content is a4, flow the corresponding preset value of pressure
Correspondence preset value is a6, the corresponding preset value of submergence is a7, the corresponding preset value of strata pressure is a8, the correspondence of recoverable reserves
Preset value is a9, the corresponding preset value of cumulative oil production is a10, the corresponding preset value of recovery percent of reserves is a11, remaining moveable oil storage
The corresponding preset value of storage is a12.
When sandstone effective thickness are more than a4, stream pressure less than a2, daily oil production less than a1, daily fluid production rate less than a3, water content
It is more than more than a9, cumulative oil production less than a8, recoverable reserves less than a7, strata pressure less than a6, submergence less than a5, hydrodynamic face
When a10, recovery percent of reserves are more than a12 more than a11, remaining moveable oil storage capacity, the production information for determining first oil well meets the
Two predetermined threshold values.
Further, in the embodiment of the present invention, the weighting of each preset value in the second predetermined threshold value can also be set
Coefficient, and the first product for obtaining that preset value and corresponding weight coefficient are multiplied is used as selecting well coefficient；
When selecting well coefficient to be more than three predetermined threshold values, the first oil well is defined as to treat abandoned wells and upper measure.
In practical application, this penetrates that the oil storage of layers apart position is more to the bigger explanation of sandstone effective thickness, therefore when the ground of the first oil well
Be that the sandstone effective thickness arrange weight coefficient when matter information includes sandstone effective thickness, by sandstone effective thickness value with it is right
Answer weight coefficient to be multiplied, obtain the second product；
When the first product and second sum of products are more than four predetermined threshold values, the first oil well is defined as treating abandoned wells
And upper measure.
Weight coefficient can be chosen according to the concrete condition of the first oil well.For example, the weight coefficient of a1 be b1, the weighting of a2
Coefficient is b2, and by that analogy, the weight coefficient of a12 is a12, and preset value is multiplied respectively with its weight coefficient, then will be multiplied
Results added, i.e. the first product and the second product addition, when the first product is bigger with second sum of products, show the first oil well
What production capacity was improved after upper measure is more, and effect is better.The 3rd predetermined threshold value and the 4th predetermined threshold value can be with the embodiment of the present invention
Set according to practical situation, the embodiment of the present invention is not specifically limited to this.
In practical application, meeting the oil well of the first predetermined threshold value and the second predetermined threshold value may recover the oil effect after upper measure
It is undesirable, therefore, in order to further determine the first oil well if appropriate for oil recovery in the embodiment of the present invention, first can also be passed through
The history oil field data of oil well judged, specifically, including：
The history oil field data of the first oil well is obtained, judges first oil well if appropriate for pre- according to the history oil field data
If measure, if it is, determining the first oil well to treat abandoned wells and upper measure.
