and step 205, adding remark information to each data point on the well group production curve.
Of course, it is understood that other variations of the above detailed flow can be made, and all such variations are intended to fall within the scope of the present invention.
A specific example is given below to illustrate the specific application of the oilfield production data processing method.
The DW oil field is put into production in 1988 and is increased by 30 years till now, the number of oil-water wells is 314, production measures are adjusted frequently, oil-water relations are very complex, single-well production effect analysis is the basis of development effect evaluation work in comprehensive adjustment and deployment research work, and the method is particularly important for adjustment of development schemes. Taking a certain injection and production unit in a DW oil field Q5 block as an example, the oil well 10-15 is put into production in 1994 in 10 months, and is regulated by four measures, and the daily production liquid is 5.6m at present31.4t of daily oil production and 79.8 percent of water, and four water wells (water injection wells) around the water production wells are respectively transferred during the 9-2013 months in 2000 and subjected to multiple horizon adjustment. In order to analyze the effective conditions of the oil wells 10-15, the production data of the injection and production unit is analyzed, and the method comprises the following steps:
(1) dividing the injection and production units according to the well pattern, and establishing the corresponding relation between the well numbers of the oil wells and the wells, wherein FIG. 3 is the corresponding relation between the oil wells and the wells in the embodiment of the invention, and the corresponding relation of the injection and production units is that the oil wells 10-15 correspond to the wells 10-13, 11-15, 11-18 and 12-19.
(2) The production data of the oil wells 10-15 and the water wells 10-13, 11-15, 11-18 and 12-19 are linked together. The production curve of the oil well 10-15 and the production curves of the water wells 10-13, 11-15, 11-18 and 12-19 are drawn in the same working table to generate the production curve of the injection and production unit 10-15 well group, and FIG. 4 is a schematic diagram of the production curve of the injection and production unit 10-15 well group in the embodiment of the invention.
(3) The well history information and the well group production curve are linked together, namely the well history information is marked on the production curve of the well group of 10-15 of the injection and production unit oil wells, so that the well history information is marked beside the corresponding data point of the production curve in a text form, and fig. 5 is a well history information marking schematic diagram in the embodiment of the invention. By marking the production horizon of the well group production curve, which is visualized by the graph in FIG. 5, the horizons of the wells 11-18 and the oil wells 10-15 during the whole production period do not correspond to each other; the wells 12-19 correspond to the wells 10-15, although in horizons, but not in time. Therefore, the effect relationship between the wells 10-13 and 11-15 and the wells 10-15 can be analyzed in the subsequent analysis.
(4) And linking the remark information with the well group production curve, and adding the remark information to each data point on the well group production curve. When any data point on the production curve is clicked by a mouse, a prompt text box marked with remark information appears, and fig. 6 is a schematic diagram of remark information marking in the embodiment of the invention. The oil well 10-15 has high water content in 3 months to 1 month in 2002, only the corresponding water well 11-15 exists in the period, but the oil well 10-15 has high water content in 3 months in 2000, and the water well 11-15 starts to inject water in the corresponding position in 9 months in 2000, so that the high water content is not the water injected by the water well 11-15. Identifying remark information of each point by clicking a data point on a curve (figure 6) shows that the reason that the daily yield of the oil well 10-15 is increased during 6 months to 2000 months and 3 months in 1999 is that a phi 70 big pump is replaced, the horizon has bottom water, and therefore, the replacement of the big pump extract causes the bottom water breakthrough, and the oil well has high water content. The water content is reduced in the 10 th-2014 th month from 2012, and the 10-15 performance of the oil well is characterized by liquid stabilization, oil increase and water content reduction due to the effect of the water well 11-15 profile control and flooding. The water content is reduced in 3 months to 2017 in 2015, the oil well 10-15 is characterized by liquid increase, oil increase and water reduction due to the effect of the water well 10-13 on the profile control and flooding. As can be quickly seen from the above analysis, the oil well 10-13 is two-way affected, and the affected part is connected with the water well 10-13 and the water well 11-15.
The above example is only an example of processing production data of a certain injection and production unit in an oil field research work area, and a plurality of injection and production units need to generate production data for processing currently and in the future.
In summary, in the method provided by the embodiment of the invention, the corresponding relation between the oil well and the water well in the injection and production unit of the oil field is determined; combining the production data of the oil well and the water well according to the corresponding relation of the oil well and the water well to generate a production curve of the injection and production unit well group; the method comprises the steps that well history information is marked on a well group production curve, wherein the well history information comprises data of production stratum data and production measure change information of an oil well and a water well from production to the current production stratum; and adding remark information to each data point on the well group production curve. In the process, the generated data of the oil well and the water well in each injection and production unit are combined, so that the process of generating the production curve of the injection and production unit well group is realized, and the obtained production curve of the injection and production unit well group comprises well history information and remark information, so that frequent switching among multiple groups of generated data is not needed, and the working efficiency is high.
