Description
Technical Field
The embodiment of the invention relates to the technical field of reservoir fluid evaluation, in particular to a quantitative calculation method and device for gas-oil ratio, computer equipment and a storage medium.
Background
In the oilfield, the ratio of the gas production and the oil production of an oil well is commonly referred to as the gas-oil ratio, which indicates how much cubic natural gas is produced per ton of crude oil produced. In the early stage of oil and gas field exploration, the gas-oil ratio of an oil reservoir is calculated by obtaining the ratio of formation gas to oil by adopting a cable stratum test and drill pipe stratum test method, and the property of reservoir fluid can be identified according to the magnitude of the gas-oil ratio.
At present, the method for identifying the property of the stratum fluid at home and abroad mainly comprises three technical means of logging, well logging and testing. The logging technology can directly obtain the characteristics of underground lithology and oil-gas content, has wide application in fluid identification, but mainly adopts qualitative identification, depends on personal experience judgment, and cannot be quantitatively evaluated. The well logging method is mainly based on comprehensive identification of response characteristics of oil gas by each well logging curve, and common methods include a three-porosity difference method, a neutron-density intersection method, a porosity-resistivity intersection method, a volume compression coefficient-poisson ratio intersection method, a two-dimensional nuclear magnetic identification method and the like, but under the conditions of complex and various lithology and reservoir space types, low pores, low permeability and strong heterogeneity, or small electrical differences of oil, gas and water layers, and the like, the conventional well logging technical means cannot identify reservoir fluid properties. The cable stratum test can achieve quantitative fluid identification by carrying out real-time fluid analysis through pressure measurement sampling operation, but the result is only to evaluate a certain depth point, and the cost and engineering risk are very high if continuous evaluation per meter is carried out. The drill rod stratum test can not accurately identify the oil-gas interface under the condition of the oil-gas outlet of the test section, and the drill rod stratum test has high operation cost and high operation risk under the complex working condition, so that the technology is relatively not popular in field operation.

Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts steps as a sequential process, many of the steps may be implemented in parallel, concurrently, or with other steps. Furthermore, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example 1
Fig. 1 is a flowchart of a gas-oil ratio quantitative calculation method according to an embodiment of the present invention. The embodiment is applicable to the condition of continuously and quantitatively calculating the vertical gas-oil ratio of the reservoir, the method can be executed by the gas-oil ratio quantitative calculating device provided by the embodiment of the invention, and the device can be realized by hardware and/or software and can be generally integrated in computer equipment. As shown in fig. 1, the method specifically comprises the following steps:
s11, acquiring a gas-oil ratio sample of a preset pumping sampling point based on a cable stratum testing technology, wherein the preset pumping sampling point is positioned in at least one drilled well.
The cable stratum testing technology is that after oil gas is found to be displayed in the drilling process, a stratum tester is used for logging in stratum by using a cable, parameters such as stratum temperature and the like of fluid in stratum can be obtained, stratum fluid sampling, reservoir pressure and stratum pressure gradient testing can be completed, a reservoir oil-water interface is determined, and reservoir permeability interpretation and productivity evaluation are carried out. And according to the parameters obtained by cable stratum testing at the preset pumping sampling point, calculating to obtain a gas-oil ratio sample of the preset pumping sampling point. Specifically, the cable formation test pumping sampling can be performed in a water-based slurry environment, 20-50 preset pumping sampling points can be selected from each drilled well to perform sampling, so as to obtain 20-50 gas-oil ratio samples, specifically, one or more preset well depth positions can be selected from part or all of the drilled wells as preset pumping sampling points to perform cable formation test, wherein each drilled well can be located in the same area, and accordingly, the reservoir fluid properties of the area can be accurately evaluated according to the obtained gas-oil ratio profile.
Optionally, based on a cable formation testing technique, obtaining a gas-oil ratio sample of a preset pump sampling point includes: acquiring a spectrum analysis chart of a preset pumping sampling point; and searching the gas-oil ratio with the lowest water content from the spectrum analysis chart to be used as a gas-oil ratio sample. Specifically, for the cable stratum test at each preset pumping sampling point position, a spectrum analysis chart can be drawn, and because the spectrum is influenced by mud filtrate, when the water content is higher, the error of the gas-oil ratio is larger, so that the point with the lowest water content is found in the change curve of the optical density along with time to correspond to the representative stratum fluid characteristic, namely, the gas-oil ratio corresponding to the point with the lowest water content is used as a gas-oil ratio sample. Illustratively, in the spectrum analysis chart obtained when the cable stratum test sampling operation is carried out at the depth of a well 3404.00 m, the water content of the vicinity of 109 minutes of pumping sampling operation time is less than one percent and reaches the lowest, and the corresponding gas-oil ratio is 347 cubic meters per cubic meter, so that the value of the gas-oil ratio is more reliable, and the point data is preferably used as modeling parameters.
S12, acquiring a hydrocarbon component parameter sample corresponding to the gas-oil ratio sample by adopting a fluid logging technology.
Wherein, optionally, the fluid logging technique is FLAIR real-time fluid logging technique. The FLAIR (Fluid Logging & Analysis In Real time) real-time Fluid Logging technology is the latest generation of Fluid Logging technology, has the characteristics of quantitative constant temperature, multiple components, high precision, dual-gas-path detection at an inlet and an outlet, strict quality control and the like, and can reflect the change of stratum Fluid more truly compared with the conventional Fluid Logging technology. Specifically, a fluid logging technology is adopted to obtain hydrocarbon component parameter samples corresponding to the gas-oil ratio samples, namely hydrocarbon component parameters at the same preset pumping sampling point positions. Among other hydrocarbon component parameters, methane (C1), ethane (C2), propane (C3), isobutane (iC 4), n-butane (nC 4), isopentane (iC 5), n-pentane (nC 5), n-hexane (nC 6), n-heptane (nC 7), and n-octane (nC 8), and the like.
S13, establishing a relation model between the gas-oil ratio and the hydrocarbon component parameters according to the gas-oil ratio sample and the hydrocarbon component parameter sample.
After the gas-oil ratio sample and the corresponding hydrocarbon component parameter sample are obtained, a relation model between the gas-oil ratio and the hydrocarbon component parameter can be established. Optionally, establishing a relation model between the gas-oil ratio and the hydrocarbon component parameter according to the gas-oil ratio sample and the hydrocarbon component parameter sample comprises the following steps: determining a light-to-heavy component value sample from the hydrocarbon component parameter sample; and establishing a relation model according to the gas-oil ratio sample and the corresponding light-heavy component ratio sample. Specifically, according to the measurement principle of the FLAIR real-time fluid logging technology, the hydrocarbon component characterizes the components of the fluid in the gas phase after the underground fluid is flashed, so that the light-heavy component ratio (i.e. the ratio of the light component to the heavy component) can reflect the characteristics of the fluid, and a relation model between the gas-oil ratio and the light-heavy component ratio can be established so as to better determine the gas-oil ratio profile later.
Further optionally, the light-to-heavy component values are: (c1+c2)/(c3+c4+c5+c6); wherein C1 is methane, C2 is ethane, C3 is propane, C4 is butane, C5 is pentane, C6 is hexane, and c4=ic4+n4, c5=ic5+n5, c6=ic6+n6, i.e. the ratio between the light components C1 and C2 and the heavy components C3, C4, C5 and C6 in the hydrocarbon component parameter sample is preferably used as the light-heavy component ratio to establish a relation model in combination with the characteristics of each hydrocarbon component parameter in different types of reservoirs.
Further optionally, the relationship model is: y=217.25 x 1.168 Wherein y is the gas-oil ratio, and x is the light-heavy component ratio. Specifically, the relationship model can be obtained by fitting the obtained correspondence between the gas-oil ratio sample and the light-heavy component value, the light-heavy component value is taken as an independent variable, and the gas-oil ratio is taken as a dependent variable, so that the gas-oil ratio profile of the preset well section can be obtained by subsequent calculation according to the light-heavy component value which varies along with the well depth.
S14, calculating the gas-oil ratio profile of the preset well section according to the relation model.
Specifically, after the relation model is determined, hydrocarbon component parameters of any well depth position in the whole preset well section can be obtained through a FLAIR real-time fluid logging technology, and the obtained hydrocarbon component parameters can be substituted into the relation model to determine the gas-oil ratio of any well depth position, so that the gas-oil ratio profile of the whole preset well section is determined, and continuous quantitative calculation of the gas-oil ratio is realized. The gas-oil ratio of any well depth position can be determined by calculating the corresponding light-heavy component value from the obtained hydrocarbon component parameter and substituting the light-heavy component value into the relation model obtained by the fitting. The preset well section may be a preset well depth range in the drilled well or the planned well in any position in the area where each drilled well is located, and the preset well depth range is 3760-3840 meters.
On the basis of the above technical solution, optionally, before establishing the relationship model between the gas-oil ratio and the hydrocarbon component parameters according to the gas-oil ratio sample and the hydrocarbon component parameter sample, the method further includes: and normalizing the hydrocarbon component parameter sample. Specifically, the magnitude of the hydrocarbon component parameter value of the original fluid logging can be influenced by various factors such as geology and engineering, so that the accuracy of the calculation result can be effectively improved by normalizing each hydrocarbon component parameter sample. The normalization can be performed specifically by the following formula:
wherein X is m Actual measured value of a hydrocarbon component parameter, X, representing a predetermined pump sampling point position min Representing the minimum value, X, of a parameter corresponding to the hydrocarbon composition of this type in the wellbore section max Represents the highest value of the hydrocarbon component parameter in the corresponding wellbore section, and X represents the normalized value of the hydrocarbon component parameter.
According to the technical scheme provided by the embodiment of the invention, cable stratum testing is performed on preset pumping sampling points in each drilled well to obtain a gas-oil ratio sample, then a fluid logging technology is adopted to obtain a hydrocarbon component parameter sample corresponding to the gas-oil ratio sample, so that a relation model between the gas-oil ratio and the hydrocarbon component parameter is established, and then the gasoline ratio profile of a preset well section can be calculated according to the relation model. By adopting the quantitative evaluation method based on the combination of the fluid logging parameters and the cable stratum test, the vertical gas-oil ratio change of the reservoir is continuously and quantitatively calculated, so that the quantitative evaluation of the reservoir fluid property is realized, and the efficiency and the coincidence rate of the reservoir fluid property identification are improved.
