Description
Technical Field
The embodiment of the invention relates to the field of geophysical, in particular to the technical field of energy development of unconventional oil and gas reservoirs. More particularly, the embodiment of the invention relates to a method, a device and a medium for deploying injection and production wells of a fracture-cavity type oil reservoir.
Background
This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
Fracture-cavity type oil reservoir reservoirs, such as the Ordovician carbonate fracture-cavity type oil reservoir reservoirs in the Tarim basin, provide important fields for the transportation and gathering of petroleum and natural gas. The fracture-cavity type oil reservoir body spreading plane is extremely irregular, a plurality of sets of longitudinal overlapping are adopted, the space combination of the fracture-cavity structure is extremely complex, and the control and the utilization of the reserves in the space need to be considered for improving the recovery ratio.
At present, the conventional sandstone reservoir injection and production well deployment mostly adopts a staggered deployment mode, namely, a water injection well row and an oil production well row are staggered in a regular injection and production well pattern (such as a row-column well pattern and an area well pattern) so as to realize the establishment of different injection and production well pattern modes, but the staggered deployment mode has higher requirements on the integrity of an oil layer structure, the stability of oil layer distribution, internal and external connectivity, a flow coefficient and an oil-containing boundary position. Because the fracture-cavity type oil reservoir is strong in heterogeneity and scattered in oil reservoir distribution, if the staggered deployment mode is adopted, the water breakthrough time of an oil well in the main penetration direction of the oil reservoir is short, a water channeling channel is formed too early, and the water drive effect is reduced, so that the staggered deployment mode cannot be applied to the deployment of an injection-production well pattern of the fracture-cavity type oil reservoir.
In the prior art, an irregular point water injection mode can be adopted for injection and production well deployment, and although the deployment mode can be used for the injection and production well deployment under the conditions that the oil field area is small, the oil layer distribution is irregular and a regular water injection well pattern is difficult to arrange, the irregular point water injection mode is only limited to the injection and production well pattern based on the relation between a plane water injection well and an oil well and cannot be used as a feasible deployment scheme suitable for the injection and production well pattern of the fracture-cavity oil reservoir.
In conclusion, the existing injection-production well deployment methods cannot be well applied to the deployment of the injection-production well pattern of the fracture-cavity type oil reservoir, so that a deployment scheme of the injection-production well of the fracture-cavity type oil reservoir is urgently needed to be designed.

Detailed Description
The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments. It is understood that these embodiments are given solely for the purpose of enabling those skilled in the art to better understand and to practice the invention, and are not intended to limit the scope of the invention in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As will be appreciated by one skilled in the art, embodiments of the present invention may be embodied as a system, apparatus, device, method, or computer program product. Accordingly, the present disclosure may be embodied in the form of: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
According to the embodiment of the invention, the invention provides a method and a device for deploying an injection and production well of a fracture-cavity type oil reservoir, a medium and computing equipment. Moreover, any number of elements in the drawings are by way of example and not by way of limitation, and any nomenclature is used solely for differentiation and not by way of limitation.
In this context, it is to be understood that the several concepts involved have the following meanings:
the fracture-cave type oil reservoir is also called fracture-cave type, and the fracture-cave type oil reservoir related to the embodiment of the invention is mainly carbonate fracture-cave type oil reservoir, such as Ordovician carbonate fracture-cave type oil reservoir in a Tarim basin.
The weathering crust oil reservoir is an oil-gas reservoir controlled by a fracture-cavity body formed by karst action, the heterogeneity of the reservoir is extremely strong, the oil-gas is mainly controlled by the fracture-cavity body, and a uniform temperature and pressure system and a uniform oil-gas-water interface are arranged in the relatively independent fracture-cavity body. The currently discovered oil and gas reservoirs are mainly weathered shell oil and gas reservoirs, the oil field of Tanhe in the south of the Tanhe is a typical buried hill weathered shell oil reservoir distribution area, and the weathered shell between the eagle mountain group layers in the north of the tower is a large condensate gas reservoir distribution area and is formed by the distribution of a series of superposed connecting pieces of the oil (gas) reservoirs controlled by a crack body. Because the connectivity of the weathering crust crack body has important influence on the occurrence and the output of oil gas, the weathering crust crack body can be further divided into isolated constant volume cave type oil-gas reservoirs and communicated crack-hole type oil-gas reservoirs according to the composition of the crack body, the two types of oil-gas reservoirs have different reservoir distribution, different seepage characteristics and different oil-gas output, and the division is greatly beneficial to the modeling of exploration and development of the oil-gas reservoirs.
A dissolved oil reservoir is divided into a single-branch plate type and a branch type; in the solution reservoir, cracks and holes develop comparatively, a main fracture zone provides a main channel for karst action, associated secondary fracture provides favorable conditions for the development of the karst, and particularly directional cracks provide main communication channels and paths among wells.
The ancient underground river oil reservoir has cracks which mainly play a role in longitudinal communication of layered underground rivers, underground river pipelines are main communication channels, and branch underground rivers are also associated on the main underground rivers. In addition, the ancient underground river oil reservoir has the characteristic of longitudinal separation, namely the underground river in the deep part is separated from the underground river in the shallow part obviously.
The stage of the deployment and construction of the injection and production well pattern is the stage characteristic presented by each stage of the injection and production well pattern; firstly, the main goal of well pattern construction in the basic well pattern stage is to effectively use geological reserves, the construction method is 'well arrangement by holes and development by holes', namely, the development wells are deployed based on the distribution condition of the holes, and the heterogeneity of the karst cave type reservoir body development determines that the basic well pattern has larger well spacing and irregular shape, so the stage has the characteristics of larger well spacing and irregular distribution. Secondly, in the injection and production well pattern stage, injection and production well patterns are deployed based on reservoir body spreading with the purposes of supplementing stratum energy and improving reserve control and utilization degree, injection and production relations are gradually constructed, and irregular well pattern forms are established. And thirdly, optimizing and adjusting the well pattern in the well pattern adjusting stage, wherein the main purpose of optimizing and adjusting the well pattern is to enlarge the water injection spread range to realize fine water injection, the construction mode is based on the remaining oil distribution adjustment, the injection-production relation is optimized by a system, the injection-production well pattern is locally adjusted, and the well pattern is timely optimized and adjusted.
A plurality of, two or more.
Moreover, any number of elements in the drawings are by way of example and not by way of limitation, and any nomenclature is used solely for differentiation and not by way of limitation.
The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the invention.
The inventor finds that a staggered deployment mode and an irregular point-like water injection mode adopted by injection and production well deployment in the prior art cannot be used as a feasible deployment scheme applied to an injection and production well pattern of a fracture-cavity type oil reservoir.
In addition, the arrangement of the fracture-cavity type oil reservoir injection-production well pattern has the stage characteristic, namely the arrangement construction of the fracture-cavity type oil reservoir injection-production well pattern needs to pass through the whole life cycle process of a basic well pattern, an injection-production well pattern and an adjustment well pattern; and the existing injection and production well deployment mode is difficult to meet the stage characteristics of each stage.
In order to overcome the problems in the technology, the invention provides a method and a device for deploying a fracture-cavity type oil reservoir injection-production well, a medium and computing equipment. The method comprises the steps of obtaining multi-dimensional reservoir geological data of a fracture-cavity type oil reservoir, and configuring injection and production well deployment matched with the multi-dimensional reservoir geological data, wherein the matching relation between the multi-dimensional reservoir geological data and the injection and production well deployment comprises one or the combination of the following steps: the deployment of the injection and production direction is matched with the crack distribution direction, the deployment of the injection and production well type is matched with the size of a storage space, the deployment of the injection and production mode is matched with the communication relation of a storage body, the deployment of the injection and production mode is matched with a longitudinal structure, the deployment of the injection and production relation is matched with a fracture-cavity structure, and the deployment of the well pattern form is matched with the type of an oil reservoir.
The deployment method of the injection and production wells of the fracture-cavity type oil reservoir comprises the steps of carrying out multi-dimensional matching on the deployment of the injection and production wells, namely the deployment of the injection and production direction is matched with the fracture distribution direction, the deployment of the injection and production well type is matched with the scale of a reservoir space, the deployment of the injection and production mode is matched with the communication relation of a reservoir body, the deployment of the injection and production mode is matched with a longitudinal structure, the deployment of the injection and production relation is matched with a fracture-cavity structure, and the deployment of the well pattern is matched with the type of the oil reservoir; the three-dimensional deployment of the injection and production wells of the fracture-cavity type oil reservoir is realized, the injection and production structure of the injection and production well pattern of the fracture-cavity type oil reservoir realizes vector configuration, plane multi-direction and longitudinal multi-casing, and the water injection development efficiency of the oil reservoir is improved. It will be appreciated that the principles of the apparatus, medium, and computing device are similar to the system and will not be described in detail herein.
Having described the general principles of the invention, various non-limiting embodiments of the invention are described in detail below.
The embodiment of the invention can be applied to the deployment scenes of various fracture-cavity type oil reservoir injection and extraction wells, and the fracture-cavity type oil reservoir related to the embodiment of the invention comprises but is not limited to a weathering crust oil reservoir, a solution body oil reservoir, an ancient dark river oil reservoir, an oil reservoir structure formed by mixing the three oil reservoir types and other irregular oil reservoir structures. It is to be understood that, besides the above exemplary scenarios, scenarios to which the embodiments of the present invention are applicable may also be other scenarios, and are not limited herein.
A method for deployment of a fracture-cavity reservoir injection well according to an exemplary embodiment of the present invention is described below with reference to the accompanying drawings in conjunction with an application scenario. It should be noted that the above application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present invention, and the embodiments of the present invention are not limited in this respect. Rather, embodiments of the present invention may be applied to any scenario where applicable.
The embodiment of the invention provides a deployment method of an injection well of a fracture-cavity type oil reservoir, which at least comprises the following steps of:
s101, obtaining multi-dimensional reservoir geological data of the fracture-cavity oil reservoir.
The multidimensional reservoir geological data related to the embodiment of the invention comprises one or a combination of fracture distribution direction, reservoir space scale, reservoir body communication relation, longitudinal structure, fracture-cavity structure and reservoir type. Furthermore, the oil reservoir type of the fracture-cavity type oil reservoir related to the embodiment is one or a combination of a weathering crust oil reservoir, an amputative fluid oil reservoir and an ancient underground river oil reservoir. Wherein, the reservoir includes but is not limited to karst cave, hole, underground river, crack, filling cave.
In addition to the data, the multi-dimensional reservoir geological data can also comprise actual drilling well drilling reservoir types, seismic profiles, horizons, fracture interpretation results and reservoir seismic response characteristics.
S102, configuring injection and production well deployment matched with the multi-dimensional reservoir geological data.
Wherein the matching relationship between the multidimensional reservoir geological data and the injection and production well deployment comprises but is not limited to one or a combination of the following: the deployment of the injection and production direction is matched with the crack distribution direction, the deployment of the injection and production well type is matched with the size of a storage space, the deployment of the injection and production mode is matched with the communication relation of a storage body, the deployment of the injection and production mode is matched with a longitudinal structure, the deployment of the injection and production relation is matched with a fracture-cavity structure, and the deployment of the well pattern form is matched with the type of an oil reservoir. The following describes the steps of configuring the injection-production well deployment based on the matching relationship:
step one, configuring an injection-production direction matched with the crack spreading direction.
Specifically, fractures in a fracture-cavity reservoir are the primary reservoir space and communicating channels; illustratively, a fracture system in a fracture-hole reservoir is shown in FIG. 2 a. For weathering crust oil reservoirs, cracks, holes and residual karst caves provide main storage spaces, and the cracks are also main inter-well communication media; for a solution reservoir, fractures and holes develop relatively, so that main fracture zones provide main channels for karst, secondary fractures provide good conditions for the development of the karst, and particularly, directional fractures are main inter-well communication media. For a weathering crust oil reservoir and/or a dissolved gas reservoir, configuring a parallel vector direction matched with a crack spreading direction as an injection-production direction in the first step; further, a parallel vector direction matching the secondary fracture zone spreading direction is configured as a beam-injection direction. And for the ancient underground river oil reservoir, the direction parallel to the spreading direction of the main underground river is configured to be the injection and extraction direction. The injection and production well can be deployed along the injection and production direction through the first step, so that the vector direction of the injection and production well pattern is matched with the geological vector direction, and the water drive control reserve is improved.
And step two, selecting reservoir bodies deployed as water injection wells and/or oil production wells according to the size of the reservoir space.
Injection and production well types include, but are not limited to, water injection wells for water injection control reservoir acquisition and/or production wells for acquisition of a reservoir. Reservoir space size can be used to scale the amount of oil and gas stored in a reservoir; in a fracture-cavity type oil reservoir, a karst cave is a main storage space, and therefore the size of the storage space in the fracture-cavity type oil reservoir can be understood as the size of the karst cave. Specifically, the larger the scale of the reservoir space, the larger the amount of hydrocarbons stored in the reservoir, and the higher the production of hydrocarbons, and therefore the size of the reservoir space in which the water injection well is deployed is smaller than the size of the reservoir space in which the oil production well is deployed, so that more reservoir hydrocarbons are driven down and the production of hydrocarbons in the oil production well is improved. Supposing that a plurality of reservoirs distributed along the injection and production direction comprise holes and karst caves with different scales, in the second step, the karst cave scales of the plurality of reservoirs are compared, the holes and the karst caves with relatively small karst cave scales are selected according to the comparison result to be used for deploying the water injection well, and the karst caves with relatively large karst cave scales are selected to be used for deploying the oil production well. And matching the type of the injection and production well with the size of the storage space through the second step, further improving the flooding potential and controllability of the oil gas in the storage and increasing the oil gas yield of the oil production well.
And step three, configuring the deployment positions of the water injection well and/or the oil production well according to the reservoir body communication relations of different types of oil reservoirs.
The reservoir body distribution of the fracture-cavity oil reservoir has the characteristic of plane discrete distribution, and the injection-production well pattern is flexibly controlled in a plane multi-direction mode through the third step, so that the flooding potential and controllability of reservoir oil gas can be further improved, and the oil gas yield of an oil production well can be improved. The injection-production mode in the step is used for realizing multidirectional displacement.
The cracks in the fracture-cavity type oil reservoir have the function of communicating karst caves, and the cracks are important communication channels. Due to the difference of crack development and crack distribution in different types of oil reservoirs, the reservoir body communication relations of the different types of oil reservoirs have different characteristics. Specifically, the scale of cracks in the weathering crust oil reservoir is small, and a plurality of cracks are connected among the karst caves to form a reticular reservoir body communication relation; in the third step, the water injection wells matched with the weathering crust oil reservoirs are arranged at the karst caves with a plurality of communication directions, so that multidirectional displacement is realized through the water injection wells arranged in the karst caves with the plurality of communication directions. Although the scale difference of the cracks in the solution reservoir is large, the crack spreading has certain directionality; in the third step, the deployment position of the water injection well matched with the solution reservoir is the intersection position of the multiple fractures, so that the water drive control of the multiple fracture channels is realized through the water injection well deployed at the intersection position of the multiple fractures. Cracks in ancient underground river oil reservoirs are mainly used for longitudinally connecting layered underground rivers, the main underground river is a main communicating channel, and branch underground rivers are also associated on the main underground river; in the third step, the water injection well matched with the ancient underground river oil reservoir is a main underground river, and the oil extraction well matched with the ancient underground river oil reservoir is a branch underground river, so that multi-channel control is realized. Illustratively, as shown in the schematic diagram of water injection well communication relationship of fig. 2b, the water injection wells are configured as unidirectional water injection wells, bidirectional water injection wells, or multiple water injection wells depending on the direction of communication that the reservoir has.
And step four, configuring matched injection-production modes according to the longitudinal structures of different types of oil reservoirs.
And the reservoir body distribution of the fracture-cavity oil reservoir has the characteristic of longitudinal local separation, and the injection and production well pattern realizes longitudinal multi-set flexible control through the step four, so that the flooding potential and controllability of reservoir oil gas can be further improved, and the oil gas yield of the oil well can be improved. The injection-production mode in this step is used to achieve longitudinal displacement.
The longitudinal distribution of the reservoirs in different types of oil reservoirs is different, resulting in different characteristics of the longitudinal structures of the different types of oil reservoirs. The longitudinal separation of the deep underground river and the shallow underground river in the ancient underground river oil reservoir is obvious, and the injection-mining mode matched with the ancient underground river oil reservoir in the fourth step is separate injection mining or combined injection mining so as to improve the longitudinal water drive controllability, as shown in fig. 2 c. Further, the separate injection and mining can be shallow/deep segmented water injection. The broken solution reservoir is mainly divided into a main part in the longitudinal direction, so that the connectivity of the reservoir body positioned in the shallow part is better, the reservoir body positioned in the deep part is locally communicated, the injection and extraction mode matched with the broken solution reservoir in the step four is deep injection and shallow extraction, namely, the reservoir body positioned in the deep part (namely the deep layer) is deployed as a water injection well, and the reservoir body positioned in the shallow part (namely the shallow layer) is deployed as a oil extraction well, as shown in figure 2d, an artificial water injection and lifting oil-water interface is formed by the gravity difference principle, so that the longitudinal displacement is realized, and the longitudinal water drive controllability is improved.
And step five, adjusting the matched injection-production relation according to the fracture-cavity structures of different types of oil reservoirs.
In order to improve the negative influence caused by the heterogeneity of the distribution of the reservoir body of the fracture-cavity type oil reservoir, the fifth step follows the construction principle of the injection-production relationship of low-injection high-production, fracture-injection hole production and one-injection multi-production, namely the injection-production relationship is adjusted by preferentially using the construction principle of the injection-production relationship of the low-injection high-production, the fracture-injection hole production and the segmented injection-production. And fifthly, the injection-production relationship matched with the weathering crust oil reservoir is slot injection hole mining and/or low injection high mining, the injection-production relationship matched with the broken solution single-branch plate-shaped oil reservoir is slot injection hole mining and/or deep injection shallow mining, the injection-production relationship matched with the broken solution branch type oil reservoir is edge injection nuclear mining and/or deep injection shallow mining, and the injection-production relationship matched with the ancient underground river oil reservoir is deep underground river injection shallow layer underground river mining, main underground river injection and/or branch underground river mining. It is understood that "production" herein refers to deployment as a production well, and "injection" refers to deployment as a water injection well, for example, "fracture injection hole production" refers to deployment of a fracture as a water injection well and deployment of a karst cave as a production well, and for example, "side injection nuclear production" refers to deployment of a reservoir body located at the edge of a branch as a water injection well and deployment of a reservoir body located at the core of the branch as a production well, and other injection and production relationships are analogized and not described again. And fifthly, constructing a three-dimensional multi-dimensional injection-production relation for the injection-production well pattern, further improving water flooding wave and displacement efficiency and improving oil-gas yield.
And step six, configuring a matched well pattern form according to the type of the oil reservoir.
And step six, configuring matched well pattern forms for different types of oil reservoirs based on the distribution characteristics of the oil reservoir bodies of different types, so as to establish an irregular staggered well pattern which can flexibly adapt to the fracture-cavity type oil reservoir and effectively utilize the geological reserves of the fracture-cavity type oil reservoir. Specifically, the well pattern form matched with the weathering crust oil reservoir is a planar well pattern form, such as a schematic diagram of the planar well pattern form shown in fig. 2 e; the pattern of the well pattern matched with the solution reservoir is a linear pattern, the pattern of the well pattern matched with the ancient underground river reservoir is a net pattern, and the net pattern is schematically shown in fig. 2 f.
It should be noted that the execution timing and the execution sequence of the first to sixth steps are not limited, and the six steps may be executed in parallel or sequentially.
