All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The identification method of the plastic mudstone under the huge thick compact gravelly stratum provided by the embodiment of the invention can be applied to a drilling or construction trap scene, because the mudstone is under the ground, due to the normal compaction effect, the fluid in the pores can be timely discharged, the whole body is compact and is influenced by the gravity effect, the characterization phenomenon of normal compaction is presented, the identification is better in the drilling and logging processes, but the characteristic that the mudstone under the thick compact gravelly stratum in the Tarim basin storage truck depression of the Kela Su Gouzao belt is in a softer plastic fluid flow state is obviously different from the normally compacted mudstone, the existence of the mudstone can cause the engineering complexity of different degrees such as overflow, drilling blockage and the like, and the influence of the plastic mudstone under the gravelly stratum on the speed field is neglected, thereby causing the construction trap precision to be poor. Therefore, the accurate identification of the plastic mudstone under the ultra-thick gravelly layer has great significance for the safe drilling and the accurate implementation of the trap of the ultra-thick gravelly region. However, no method for identifying plastic mudstones under conglomerates exists at present.
Wherein mudstone refers to a weakly consolidated clay that undergoes moderate metaplasia (e.g., extrusion, dehydration, recrystallization, and cementing) to form a strongly consolidated rock. Mudstone is a sedimentary rock which is solidified into rock, but has unobvious bedding or is in a block shape, locally loses plasticity and does not expand immediately when meeting water. Plastic mudstone refers to a mudstone that is not compacted.
The trap is an effective space for capturing and dispersing hydrocarbons to form oil and gas aggregation, has the capability of storing the oil and gas, and can form an oil and gas reservoir when a sufficient quantity of the oil and gas enters the trap and fills the trap or occupies 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 super-thick dense gravel layer, the method including: acquiring the rock to be identified, determining whether the rock to be identified is a regional cover layer according to field outcrop data, logging data and microscopic analysis data of the rock to be identified, and if the rock to be identified is a regional cover layer, drilling data of the rock to be identified meets a first preset condition, and logging data meets a second preset condition, determining that the rock to be identified is plastic mudstone under a huge thick compact gravel layer. The identification method of the plastic mudstone under the ultra-thick dense gravel stratum can identify the plastic mudstone, so that the density of drilling fluid can be timely adjusted in the drilling process, the engineering complexity is effectively reduced, and meanwhile, the implementation of trap is facilitated.
The technical scheme of the invention is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 1 is a schematic flow chart of a method for identifying plastic mudstones under a huge thick and dense gravel layer, which is provided by an embodiment of the present invention. 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 super-thick dense gravel layer provided by the embodiment of the invention comprises the following steps:
s101, acquiring the rock to be identified.
S102, determining whether the rock to be identified is a regional cover layer according to field outcrop data, logging data and 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 a regional cover layer, so it is first required to determine that the rock to be identified is a regional cover layer, and if the rock to be identified is not a regional cover layer, the present solution is not applicable.
Wherein, the cap layer refers to a protective layer located over the reservoir that is capable of sealing the reservoir from upward escape of hydrocarbons therein. The regional cover layer is divided according to the distribution range, has the characteristics of continuity, thick layer and compactness, and the thickness is generally more than 500 meters.

The field outcrop can observe the stratum and the structural aspect, and the specific content of the stratum aspect comprises lithology, name, attitude, fossil contained, contact relation among layers, thickness of the stratum, other characteristics of the stratum and the like. The specific contents of the construction aspect include faults, folds and types thereof, the direction of joints and combination relation thereof, the combination and direction of joints in a metamorphic rock system and the direction of a regional construction line.
Logging data is data obtained by logging, the logging is closely connected with drilling, and the logging is by using methods of rock and mineral analysis, geophysics, geochemistry and the like to observe, collect, record and analyze wellbore return information such as solids, liquids, gases and the like in the while-drilling process, and optionally, the logging data comprises observation and analysis data of rock fragments in the actual drilling process and observation and analysis data of samples with different drilling indexes (drilling time, drilling pressure and the like).
Logging data is data obtained by logging, and logging is a method for measuring geophysical parameters by using the electrochemical properties, conductive properties, acoustic properties, radioactivity and other geophysical properties of a rock stratum, including acoustic time difference, natural gamma, resistivity and the like.

The distribution range of the plastic mudstone drilling data and the logging data can be determined according to a first preset condition and a second preset condition, 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 ultra-thick compact gravel stratum.
The first preset condition can be that drilling data change and are obviously abnormal in the drilling process, rock shapes are plastic and are in a block shape, and when drilling sticking occurs, the drilling data are obviously abnormal.
The second preset condition may be that the resistivity is less than or equal to 5 ohms, the acoustic time difference deviates significantly from the normal compaction line concentration, and typically, the acoustic time difference is greater than or equal to 80 microseconds.
Specifically, when the rock to be identified is regional overburden rock, drilling data of the rock to be identified meets a first preset condition, logging data meets a second preset condition, and the rock to be identified is plastic mudstone under the ultra-thick dense gravel layer.
Optionally, the method further comprises:
and classifying the plasticity degree of the rock to be identified according to the classification identification diagram of the plastic mudstone and the section diagram of the rock to be identified.
The hierarchical identification map of the plastic mudstone may be obtained in advance, or alternatively, according to a plurality of plastic mudstone samples, a hierarchical identification map of the plastic mudstone is obtained, in which the plastic mudstone is classified into a strong plastic mudstone, a stronger plastic mudstone, and a general plastic mudstone.
Specifically, the section view of the rock to be identified can be obtained during logging, and then the plastic mudstone with which strength the rock to be identified is judged according to the grading identification view of the plastic mudstone and the section view of the rock to be identified, wherein the plastic degree is classified into strong plasticity, stronger plasticity and general plasticity. Optionally, comparing the section of the rock to be identified with the hierarchical identification map of the plastic mudstone, and judging that the plastic mudstone belongs to the strength.
According to the method for identifying the plastic mudstone under the huge thick and dense gravel stratum, whether the rock to be identified is a regional cover layer or not is identified according to field outcrop data, logging data and microscopic analysis data of the rock to be identified, if the rock to be identified is the regional cover layer, drilling data of the rock to be identified meets a first preset condition, logging data meets a second preset condition, and the rock to be identified is determined to be the plastic mudstone under the huge thick and dense gravel stratum. The plastic mudstone can be identified, so that the density of drilling fluid can be timely adjusted in the drilling process, the engineering complexity is effectively reduced, and meanwhile, the implementation of trap is facilitated.

Specifically, an identification intersection map of plastic mudstone is established according to the resistivity-natural gamma, resistivity-acoustic time difference and acoustic time difference-natural gamma of the huge thick dense mudstone sample, for example: when the third preset condition of resistivity-natural gamma is met, the third preset condition is strong plastic mudstone, and the third preset condition is specifically selected according to actual conditions, and the scheme is not limited.
