Description

Technical Field

[0001] The present application belongs to the technical field of oil and gas exploration, and in particular relates to a basalt flow unit identification method and related equipment. Background Art

[0002] As an important part of the basin filling sequence, volcanic rocks have gradually become an important field of oil and gas exploration at home and abroad. Among them, basalt is the most widely distributed and has the highest proportion, and there is a vast space for exploration. The basalt lava flow formed after the basalt eruption is the result of the superposition of a single or multiple flow units, and the flow unit is a vertically and laterally continuous reservoir rock body that affects fluid flow and has similar rock physical properties. According to the statistical analysis of oil content, the oil and gas near the flow unit interface is better, especially below the top interface of the basalt formation. The oil and gas are most enriched. Therefore, it is very important to quickly and accurately identify the basalt flow unit for characterizing the favorable basalt reservoir and discovering basalt oil and gas reservoirs.

[0003] In the prior art, the identification of basalt flow units mainly adopts core and cuttings analysis, logging identification and other methods. Among them, the core analysis method is relatively reliable, but this method requires obtaining cores from underground to the surface, and continuous coring is required to see the law of lithology changes and then divide the flow units. The coring cost is high and time-consuming and labor-intensive; the cuttings analysis method has a large identification error due to the limitation of sample scale and the interference of surrounding rocks; the logging identification method usually uses the 3700 logging series to obtain relevant logging curves for comprehensive identification of flow units, but this method needs to obtain the natural potential, resistivity, emissivity and other parameters of the rock formation after all the drilling work is completed to identify the basalt flow unit. The workload is large, the cost is high, and the timeliness is poor. It cannot analyze the exploration results while drilling, so it is impossible to make exploration decisions in time.

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0043] The first aspect of the present application provides a basalt flow unit identification method, see Figure 1 , Figure 1A schematic flow chart of a basalt flow unit identification method provided in an embodiment of the present application may specifically include: S110-S120.

[0044] S110, obtaining characteristic element quality parameters that vary with drilling depth based on the basalt well section, wherein the characteristic elements include Na and K.

[0045] Exemplarily, the basalt well section in the exploration area is identified by means of cuttings logging and the like. The basalt well section is arranged in sections as the drilling depth changes. Rock samples of corresponding depths can be obtained according to the changes with the drilling depth. Different characteristic element quality parameters can be obtained from rock samples at different depths. The characteristic element quality parameters may include mass percentage content, wherein the characteristic elements include Na and K.

[0046] S120, identifying basalt flow units based on characteristic relationships between characteristic element quality parameters.

[0047] Exemplarily, the basalt flow unit is identified by the characteristic relationship between the obtained mass parameters of the Na element and the K element.

[0048] A volcanic eruption period is a relatively concentrated (quasi-continuous) volcanic activity in an eruption center. In the process of regular changes in material composition, eruption mode and eruption intensity, a set of volcanic rock combinations with genetic connections in phase sequence are formed. The lava flow of an eruption period is the result of the superposition of single or multiple flow units. The eruption interval between flow units is often very short, and there is no stable and obvious sedimentary interlayer. The interface of the flow unit is layered and intercalated in thick and continuously developed basalt. The mineral composition of basalt phenocrysts is mainly basic plagioclase, monoclinic pyroxene, orthopyroxene, olivine, etc.; the matrix is ​​mainly intermediate basic plagioclase, pyroxene and common pyroxene, etc. According to its mineral composition, the main rock-forming elements of basalt include O, Si, Al, Ti, Fe, Mg, Na, K, Ca, etc., and the main oxides include SiO2, Al2O3, Fe2O3, FeO, MgO, CaO, K2O, Na2O and H2O, etc. In general, compared with sedimentary rocks, basalt has relatively higher contents of Na, Ca, Fe, and Mg, which means that basalt contains more dark minerals (pyroxene) and basic feldspar than sedimentary rocks, while K and Si contents are relatively lower, which means that basalt contains less acidic feldspar and quartz than sedimentary rocks.

[0049] Compared with the interior of the basalt flow unit, the secondary transformation effects such as supergenesis and fluid dissolution transformation are relatively stronger near the boundary surface of the basalt flow unit. Therefore, in addition to the development of thin layers of basaltic mudstone, basaltic sandstone, basaltic tuff and other transitional lithologies with sedimentary rocks near the interface, the alteration phenomenon of basalt is also very common, and with the deepening of the alteration, it shows the characteristics of gradual "mudification", and its element content will also change significantly. Near the boundary surface of the flow unit, the element percentage content (Si, Fe, Ca, Mg, K, Na) still conforms to the characteristics of basalt. Since the basaltic mudstone, basaltic sandstone, basaltic tuff and other transitional lithologies with sedimentary rocks developed near the boundary surface of the flow unit, and because the alteration of basalt gradually "mudifies", the changes in the percentage content of Na and K elements are close to those of sedimentary rocks, that is, the percentage content of Na element is relatively reduced and the percentage content of K element is relatively increased.

[0050] Based on the above analysis, by obtaining rock samples at different depths and obtaining the changes in the mass parameters of the Na and K elements, when the mass parameter of the Na element suddenly shows a downward trend and the mass parameter of the K element suddenly shows an upward trend, the boundary surface of the flow unit at the corresponding depth is identified. Inside the flow unit, the distribution of the mass parameters of the Na and K elements shows a stable regular distribution with little fluctuation. Therefore, the flow units at different depths in the basalt well section can be identified through the characteristic relationship between the Na and K elements.

[0051] It can be explained that there are two common ways to identify flow units in the existing technology. One is to identify the lithology of rock cuttings samples obtained through rock cuttings logging, so as to identify the flow unit. However, due to the lack of stable and obvious sedimentary interlayers between basalt flow units, and the obtained rock cuttings are mostly in powder form, the error of the flow unit identified by the rock cuttings samples is large. The other is to identify the flow unit by identifying the characteristics of the logging curve such as resistivity, natural gamma value, etc. obtained through the logging curve. This method has a high accuracy rate of flow unit identification, but it is necessary to obtain all the data after all the drilling is completed before analysis and research can be carried out. It lacks timeliness and is not conducive to analyzing exploration dynamics while drilling and making exploration decisions in a timely manner. However, this application obtains rock samples of different depths through rock cuttings logging, obtains the quality parameters of characteristic elements from the rock samples, and the characteristic elements include Na and K elements. The flow unit is identified according to the characteristic relationship between Na and K elements on the boundary surface of the flow unit. Therefore, this application can quickly and accurately identify the flow unit during the drilling process, so that the basalt reservoir can be efficiently identified based on the flow unit.

[0052] According to some embodiments, identifying a basalt flow unit based on a characteristic relationship between characteristic element quality parameters includes:

[0053] Based on the Na element mass parameter and the K element mass parameter, respectively obtain a Na element mass parameter curve and a K element mass parameter curve;

[0054] The basalt flow units are identified based on the intersection of the Na element mass parameter curve and the K element mass parameter curve.

[0055] For example, the corresponding quality parameter curve can be obtained based on the Na element quality parameter and the K element quality parameter under different changes in drilling depth. The Na element quality parameter curve and the K element quality parameter curve are intertwined, and some intersection points will be generated. As can be seen from the above analysis, the Na element quality parameter will show a sudden downward trend at the boundary surface of the flow unit, while the K element quality parameter will show a sudden upward trend. Therefore, the basalt flow unit can be identified from the part between the intersection points. The flow unit can be quickly identified through the quality parameter curve, and the corresponding position of the flow unit in the basalt well section can be obtained according to the drilling depth corresponding to the intersection point.

[0056] According to some embodiments, identifying a basalt flow unit based on an intersection of a Na element quality parameter curve and a K element quality parameter curve includes:

[0057] Determining the boundary surface of the basalt flow unit according to the intersection points whose interval distance is less than a preset distance;

[0058] The basalt flow unit is identified based on the boundary surface.

[0059] For example, there are multiple intersection points between the Na element mass parameter curve and the K element mass parameter curve in a basalt well section, and the interval distances between the multiple intersection points are different. There are two or more intersection points whose interval distances are too short, less than the preset distance. The Na element mass parameter curve and the K element mass parameter curve show a "twisted" characteristic, indicating that in this part, the Na element mass parameter and the K element mass parameter fluctuate greatly, which does not conform to the element mass parameter distribution characteristics inside the flow unit. In this way, the "twisted" mass parameter curve portion can be identified as the boundary surface of the flow unit, and the portion between the two boundary surfaces is the flow unit.

[0060] For ease of understanding, Figure 2 A schematic diagram of basalt flow unit identification and comparison provided in the embodiment of the present application is as follows: Figure 2 As shown, Figure 2 The rightmost vertical table in the figure shows the Na element mass parameter curve and the K element mass parameter curve distribution diagram obtained by the basalt flow unit identification method given in this application. Figure 2The shaded part in the middle represents the flow unit corresponding to different drilling depths in the basalt well section. The shaded part can be seen to present a certain amplitude "envelope surface" feature. The part that approximately overlaps between the shaded parts is the boundary surface of the flow unit. The element logging correction profile is a schematic diagram of the flow unit obtained based on this application. The GR and SP intersection curves represent the natural gamma and natural potential curves in the logging curve, and the RT and RS intersection curves represent the deep and shallow dual lateral resistivity of the formation. The flow unit can be identified by combining the above two different logging curves. Figure 2 In the process of identifying flow units, the lithology profile of rock logging can also be used. It is easy to understand that among the commonly used flow unit identification technologies, the identification based on the characteristics of the logging curve has the highest accuracy. Figure 2 It can be seen that the basalt flow unit identification method provided in the present application is highly consistent with the flow unit identified based on the characteristics of the well logging curve.

[0061] It can be explained that a plurality of intersection points are formed between the Na element mass parameter curve and the K element mass parameter curve, and the portion formed by the intersection points whose interval distance between the plurality of intersection points is less than the preset distance is identified as the boundary surface of the basalt flow unit, and the portion between the boundary surfaces is the basalt flow unit. If the interval distance between the intersection points is less than the preset distance, it means that the mass parameters of the Na element and the K element in this portion fluctuate greatly, and do not conform to the element mass parameter distribution characteristics inside the flow unit, therefore, it can be identified as the boundary surface of the basalt flow unit, and the portion between the boundary surfaces is the basalt flow unit.

[0062] According to some embodiments, identifying a basalt flow unit based on a characteristic relationship between characteristic element quality parameters includes:

[0063] Obtain the difference between the mass parameter of the Na element and the mass parameter of the K element;

[0064] The boundary surface of the basalt flow unit is determined based on the trend of the difference;

[0065] Identification of basalt flow units based on boundary surfaces.

[0066] Exemplarily, the difference between the Na element mass parameter and the K element mass parameter corresponding to each depth can be obtained. According to the above, the Na element mass parameter will show a downward trend at the boundary surface of the basalt flow unit, and the K element mass parameter will show an upward trend. The difference between the two also changes greatly, and inside the basalt flow unit. The distribution of the Na element mass parameter and the K element mass parameter is relatively regular, and the difference between the two also changes relatively little. Therefore, at the boundary surface of the basalt flow unit, it can be identified that the difference between the Na element mass parameter and the K element mass parameter decreases from large to zero, and then increases from zero. It can be reflected that the Na element mass parameter suddenly shows a downward trend near the boundary surface of the basalt flow unit, and the K element mass parameter suddenly shows an upward trend, which is in line with the change law of the Na element and the K element at the boundary surface of the basalt flow unit. Therefore, the boundary surface of the basalt flow unit can be identified according to the difference between the Na element mass parameter and the K element mass parameter, and the basalt flow unit of the corresponding depth can be identified based on the boundary surface.

[0067] According to some embodiments, determining the boundary surface of the basalt flow unit based on the variation trend of the difference value includes:

[0068] When the difference is less than the preset value, a set of element quality parameters corresponding to the difference is obtained;

[0069] The boundary surfaces of the basalt flow unit are determined based on a set of element quality parameters.

[0070] Exemplarily, a preset value is set, and the preset value can be specifically set based on different situations. When the difference between the Na element mass parameter and the K element mass parameter is less than the preset value, it indicates that the Na element mass parameter and the K element mass parameter present opposite change trends, and the Na element mass parameter suddenly drops, while the K element mass parameter suddenly rises. Obtaining the element mass parameter set corresponding to the difference less than the preset value can indicate that the change law of some Na element mass parameters and K element mass parameters corresponding to this part of the element mass parameters conforms to the change law of Na element and K element on the boundary surface of the flow unit, and thus the boundary surface of the basalt flow unit can be determined.

[0071] According to some embodiments, further comprising:

[0072] Obtain cuttings samples based on cuttings logging;

[0073] Obtain the distribution of sensitive elements in basalt based on rock chip samples;

[0074] The basalt well section was determined based on the cuttings samples and the distribution of basalt sensitive elements.

[0075] For example, cuttings samples are obtained from cuttings logging while drilling, and the distribution of basalt sensitive elements in the cuttings samples is analyzed by element logging and other techniques, such as X-ray fluorescence spectroscopy, and the basalt well section can be identified by combining the color tone, structure and other characteristics of the cuttings samples. For example, the common colors of basalt are mainly gray-black and gray-green. Under microscopic observation, it is mostly semi-crystalline with a porphyritic structure, and the matrix is ​​an intergranular structure and an intercryptic structure. The elements that make up basalt usually include 20 trace elements such as Na, Mg, Al, Si, P, and S. Different types of elements can be selected as sensitive elements based on different situations, such as Figure 2 As shown, this application selects 6 trace elements, namely Si, Fe, Ca, Mg, Na and K. It is easy to understand that, compared with the sedimentary rock formation, the basalt well section curve is obviously represented by the Na element, Ca element, Fe element and Mg element curve shifting to the right, which is characterized by a significant relative increase in the content of Na element, Ca element, Fe element and Mg element; the K element and Si element curve shifting to the left, which is characterized by a significant relative decrease in the content of K element and Si element; based on this, the basalt well section can be identified. Specifically, the specific distribution of the content of sensitive elements can be referred to. The percentage content of Na element is 1 .79%~4.25%, 2.90% on average; Ca element percentage is 8.68%~11.41%, 10.40% on average; Fe element percentage is 12.13%~13.65%, 12.63% on average; Mg element percentage is 5.04%~7.42%, 6.52% on average; K element percentage is 0.76%~2.26%, 1.46% on average; Si element percentage is 38.00%~50.13%, 45.05% on average. Thus, the present application can identify basalt well sections through the characteristics of rock cuttings samples and the distribution of sensitive elements, thereby improving the accuracy of identifying basalt well sections.

[0076] According to some embodiments, further comprising:

[0077] Remove outliers in the distribution of sensitive element contents in basalt;

[0078] The basalt well section was determined based on the cuttings samples and the distribution of basalt sensitive elements after removing outliers.

[0079] For example, when analyzing the distribution of basalt-sensitive element contents in rock cuttings samples by means of X-ray fluorescence spectroscopy or the like, some points with relatively large deviations, namely outliers, may appear. There may be many reasons for the outliers. Outliers may be generated due to improper handling of the obtained rock cuttings samples during cleaning or other processing, or technical errors in the X-ray fluorescence spectroscopy analysis process. If the data of these outliers are analyzed, errors will be caused in determining the basalt well section. Therefore, before determining the basalt well section based on the rock cuttings samples and the distribution of basalt-sensitive element contents, the outliers in the distribution of basalt-sensitive element contents can be removed, thereby improving the accuracy of determining the basalt well section.

[0080] The basalt flow unit identification method is described above, and the basalt flow unit identification device in the embodiment of the present application is described below.

[0081] See also Figure 3 In the embodiments of the present application, an embodiment of a basalt flow unit identification device is described, which may include:

[0082] An acquisition module 301 is used to acquire characteristic element quality parameters under different changes with drilling depth based on the basalt well section, wherein the characteristic elements include Na and K elements;

[0083] The identification module 302 is used to identify the basalt flow unit based on the characteristic relationship between the characteristic element quality parameters.

[0084] According to the basalt flow unit identification device provided by the above embodiment, by obtaining rock samples at different depths and obtaining the changes in the mass parameters of the Na element and the K element therefrom, when the mass parameter of the Na element suddenly shows a downward trend and the mass parameter of the K element suddenly shows an upward trend, the flow unit boundary surface of the corresponding depth is identified, and inside the flow unit, the distribution of the mass parameters of the Na element and the K element shows a stable regular distribution with little fluctuation. Therefore, the flow units at different depths in the basalt well section can be identified through the characteristic relationship between the Na element and the K element.
