Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method for identifying the plastic mudstone under the huge thick compact conglomerate layer can be applied to a drilling or structural trap scene, because the mudstone is under the ground due to the normal compaction action, fluid in pores can be removed in time, the whole body is compact, the characterization phenomenon of normal compaction is presented under the influence of gravity, the identification is better in the drilling and logging processes, but the mudstone under the thick layer compact conglomerate of the depressed and restrained construction zone of a tree basin garage usually has the characteristic of soft plastic fluid flow, and is obviously different from the normally compacted mudstone, the existence of the mudstone can cause engineering complexity of overflow, drilling sticking and the like in different degrees, and the influence of the plastic mudstone under the conglomerate on a speed field is larger, so that the structural trap is poor in the compaction precision. Therefore, the accurate identification of the plastic mudstone under the huge and thick conglomerate layer has great significance for the safe drilling and the accurate implementation of the trapping of the huge and thick conglomerate area. However, there is currently no method of identification of plastic mudstones under conglomerates.
Wherein, the mudstone refers to the strong consolidation rock formed by the clay with weak consolidation through the moderate after-growth effect (such as extrusion, dehydration, recrystallization and cementation). Mudstone is sedimentary rock which is consolidated into rock but has no obvious bedding or is in a block shape, has local plasticity loss and does not immediately expand when meeting water. Plastic mudstone refers to poorly compacted mudstone.
The trap is an effective space for capturing dispersed hydrocarbons to form oil gas accumulation, has the capacity of storing oil gas, and can form an oil gas reservoir when enough oil gas enters the trap to fill the trap or occupy a part of the trap.
In view of the above problems, an embodiment of the present invention provides a method for identifying plastic mudstone under a huge thick compact conglomerate layer, including: the method comprises the steps of obtaining rocks to be identified, determining whether the rocks to be identified are regional cover layers according to field outcrop data, logging data and microscopic analysis data of the rocks to be identified, and determining the rocks to be identified as plastic mudstones under the ultra-thick compact conglomerate layer if the rocks to be identified are the regional cover layers, the drilling data of the rocks to be identified meet first preset conditions and the logging data meet second preset conditions. The method for identifying the plastic mudstone under the huge thick compact conglomerate layer can identify the plastic mudstone, so that the density of the drilling fluid can be adjusted in time in the drilling process, the engineering complexity is effectively reduced, and the confinement in the implementation is facilitated.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a schematic flow chart of a method for identifying plastic mudstone under a huge thick compact conglomerate layer according to an embodiment of the present invention, which may be implemented by any device for implementing the method for identifying plastic mudstone under a huge thick compact conglomerate layer, and the device may be implemented by software and/or hardware. In this embodiment, the apparatus may be integrated in an electronic device. As shown in fig. 1, the method for identifying plastic mudstone under a massive dense conglomerate layer provided by the embodiment of the invention comprises the following steps:
and S101, obtaining the rock to be identified.
S102, determining whether the rock to be identified is a regional cover layer or not according to the field outcrop data, the logging data and the microscopic analysis data of the rock to be identified.
It should be noted that the present solution is applied to the basis that the rock to be identified is the regional cap rock, and therefore, it is first required to determine that the rock to be identified is the regional cap rock, and if the rock is not the regional cap rock, the present solution is not applicable.
Wherein, the cap layer refers to a protective layer located above the reservoir layer capable of blocking the reservoir layer from upward escape of hydrocarbons therein. The regional cover layer is divided according to the distribution range, has the characteristics of continuity, thick layer shape and compactness, and the thickness is generally more than 500 meters.
The field outcrop data is data obtained by field outcrop observation, the field outcrop observation is the best method for investigating or researching the geological profile along the way, and various field tools and instruments carried with the person can assist in improving the observation quality. The stratum and the construction aspect can be observed through the field outcrop, and the specific contents of the stratum aspect comprise lithology, name, attitude, contained fossil, contact relation among layers, thickness of rock stratum, other characteristics of rock stratum and the like. Specific contents of construction aspects comprise faults, folds and types thereof, the directions and combination relations of joints, the combination and direction of the joints in metamorphic rock series and the direction of regional construction lines.
The logging data is data obtained by logging, and logging and well drilling are closely related, wherein the logging is to observe, acquire, collect, record and analyze wellbore return-out information such as solid, liquid, gas and the like in the process of drilling by using methods such as rock and mineral analysis, geophysical and geochemistry, and optionally, the logging data comprises observed and analyzed data of rock debris in the actual drilling process and observed and analyzed data of samples with different drilling indexes (drilling time, drilling pressure and the like).
The logging data are obtained by logging, and the logging is a method for measuring geophysical parameters including acoustic wave time difference, natural gamma rays, resistivity and the like by utilizing the geophysical characteristics such as electrochemical characteristics, conductive characteristics, acoustic characteristics, radioactivity and the like of rock strata.
And the microscopic analysis comprises observation and analysis of the diagenetic degree, lithology, hardness, sorting, rounding, cementing condition and the like of the rock.
Specifically, the method includes the steps of obtaining field outcrop data, logging data and microscopic analysis data of the rock to be recognized, determining whether the rock to be recognized is a regional cover layer according to the field outcrop data, logging data and microscopic analysis data of the rock to be recognized, and enabling the specific judgment that the rock to be recognized is the regional cover layer to be similar to the implementation mode in the prior art, and therefore the detailed description is omitted here.

Because the drilling data and the logging data of the plastic mudstone under the huge thick compact conglomerate layer are different from those of the normally compacted mudstone, the rock to be identified can be determined to be the plastic mudstone under the huge thick compact conglomerate layer only when the drilling data and the logging data of the rock to be identified meet the distribution range of the drilling data and the logging data of the plastic mudstone. And when the drilling data of the rock to be identified meets the first preset condition and the logging data meets the second preset condition, the rock to be identified is the plastic mudstone under the huge thick compact conglomerate layer.
The first preset condition can be that the drilling data are changed and obviously abnormal in the drilling process, the rock is plastic and block-shaped, and the drilling data are obviously abnormal when the drilling sticking occurs.
The second predetermined condition may be that the resistivity is less than or equal to 5 ohms, and the acoustic time difference is significantly offset from the normal compaction profile, typically 80 microseconds.
Specifically, when the rock to be identified is regional cover rock, the drilling data of the rock to be identified meets a first preset condition, and the logging data meets a second preset condition, the rock to be identified is plastic mudstone under a huge and thick compact conglomerate layer.
Optionally, the method further includes:
and grading the plasticity degree of the rock to be identified according to the grading identification diagram of the plastic mudstone and the section diagram of the rock to be identified.
The grading identification chart of the plastic mudstone can be obtained in advance, optionally, the grading identification chart of the plastic mudstone is obtained according to a plurality of plastic mudstone samples, and in the grading identification chart, the plastic mudstone is divided into strong plastic mudstone, strong plastic mudstone and general plastic mudstone.
Specifically, a profile of the rock to be identified can be obtained during logging, and then according to the grading identification chart of the plastic mudstone and the profile of the rock to be identified, the strength of the rock to be identified is judged to be the plastic mudstone, and the plasticity degree is divided into strong plasticity, strong plasticity and general plasticity. Optionally, the section of the rock to be identified is compared with the grading identification chart of the plastic mudstone, and the plastic mudstone with the strength is judged.
According to the method for identifying the plastic mudstone under the huge thick and compact conglomerate layer, the rock to be identified is obtained, whether the rock to be identified is the regional cover layer is identified according to the field outcrop data, the logging data and the microscopic analysis data of the rock to be identified, if the rock to be identified is the regional cover layer, the drilling data of the rock to be identified meets a first preset condition, and the logging data meets a second preset condition, the rock to be identified is determined to be the plastic mudstone under the huge thick and compact conglomerate layer. The plastic mudstone can be identified, so that the density of the drilling fluid can be adjusted in time in the drilling process, the engineering complexity is effectively reduced, and the implementation of trap is facilitated.
