Description

Technical Field

[0001] The utility model relates to the field of drilling sampling equipment, in particular to a real-time core temperature and pressure collection device in a drilling sampler. Background Art

[0002] Drilling sampling is the most direct and effective way to obtain formation parameters in the drilling field. Drilling sampling is divided into two different methods: drilling sampling and rope salvage sampling. The rope salvage method reduces the time of frequent drilling and can effectively save drilling time in deep and ultra-deep wells. It is a very efficient coring method. In the drilling sampling work, real-time acquisition of the temperature and pressure parameters of the formation core is an important aspect of obtaining the in-situ core environment data of the formation.

[0003] A Chinese utility model patent with publication number CN216130921U discloses a real-time core temperature and pressure acquisition device in a drilling sampler, which is achieved by assembling a collection component wrapped by a combined outer shell and installing it in the drilling sampler, and then lowering it to the bottom of the well, so as to obtain and store the core temperature and pressure information in real time. Although it achieves the effect of obtaining and storing the core temperature and pressure information in real time, since its outer shell is a multi-section combined structure, if it is improperly used or an unexpected situation occurs at the bottom of the well, it may cause a bump and damage to the outer shell, thereby causing damage to the internal collection component and affecting the progress of information collection.

[0004] Therefore, a real-time core temperature and pressure collection device in a drilling sampler is provided to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] The utility model provides a real-time core temperature and pressure collection device in a drilling sampler, aiming to solve the problem that the existing real-time core temperature and pressure collection device in the background technology has a multi-section combined structure as its outer shell. If it is bumped due to improper use or an unexpected situation at the bottom of the well, it may damage the outer shell, thereby causing damage to the collection components inside it, affecting the progress of information collection.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a real-time core temperature and pressure collection device in a drilling sampler, comprising a collector housing of an integrated hot-melt design installed inside a rope coring drilling sampler and a collection mechanism arranged in the collector housing for real-time collection of core temperature and pressure, the collection mechanism comprising a storage chip, a temperature sensor, a humidity sensor and a battery electrically connected in sequence, and a protective mechanism is arranged on the collector housing;

[0009] In order to further protect the collection mechanism, the protection mechanism includes a protective shell that is sleeved on the outside of the collector shell and has open and through-type design at both ends. An upper end cover that is sealed is screwed on one end of the protective shell. A tubular protective airbag is inserted into the protective shell through a pipe opening at one end of the upper end cover and is used to sleeve the collector shell for protection. A lower end cover that is sealed and fixedly installed with the collector shell is screwed on the end of the protective shell opposite to the upper end cover. A detachable protective shell is sleeved on the collector shell with an integrated design, and a protective airbag is installed in the protective shell. The upper end cover seals the protective airbag in the protective shell. The lower end cover is rotated from the bottom of the protective shell, and the collector shell connected to the lower end cover is screwed into the center of the protective airbag, thereby protecting the collector shell, so that it has better protection capabilities in the underground environment, avoiding damage to the shell and affecting the collection of information by the internal collection components.

[0010] Preferably, in order to prevent the protective airbag from slipping, a retaining ring for limiting the protective airbag is fixedly installed on the inner wall of the protective shell near the lower end cover. The distance between the retaining ring and the upper end cover is consistent with the length of the protective airbag, and it contacts the bottom of the protective airbag, thereby ensuring that the protective airbag is stably and reliably installed in the protective shell.

[0011] Preferably, in order to facilitate finding the protective shell, a number of evenly arranged reflective patches are fixedly installed on the outer wall of the protective shell. If the collection mechanism accidentally detaches underground, it can rely on the airbag to float on the water surface underground, and the reflective patches reflect light spots to facilitate identification and positioning, and facilitate salvage, so as to effectively obtain data information.

[0012] Preferably, in order to facilitate data transmission, the collection mechanism also includes a data transmission port electrically connected to the storage chip, and the data transmission port is fixedly mounted on the collector housing at an end opposite to the lower end cover. The collection mechanism uses the data transmission port to connect to a computer, mobile phone, or smart tablet via a data cable after salvage to quickly acquire information data.

[0013] Preferably, in order to prevent the underground environment and the work site from causing wear and tear on the data transmission port, a rubber plug is inserted into the data transmission port. When no data is transmitted, the rubber plug is inserted into the data transmission port to achieve the purpose of protecting the data transmission port.

[0014] Preferably, in order to verify the operation of the collection mechanism, the collection mechanism also includes an indicator light group consisting of four LED lamp beads electrically connected to the storage chip, temperature sensor, humidity sensor and battery respectively. The indicator light group is fixedly mounted on the collector housing and arranged coplanar with the data transmission port. The indicator light group indicates whether the storage chip, temperature sensor, humidity sensor and battery are operating, thereby avoiding repeated measurements due to equipment failure, saving time and effort.

[0015] (III) Beneficial effects

[0016] The real-time collection device is constructed by installing a detachable protective shell on the integrated collector shell, installing a protective airbag in the protective shell, and sealing the protective airbag in the protective shell with an upper end cover. The lower end cover is rotated from the bottom of the protective shell, and the collector shell connected to the lower end cover is screwed into the center of the protective airbag, thereby protecting the collector shell and making it have better protection capabilities in the underground environment, avoiding damage to the shell and affecting the collection of information by the internal collection components.

[0017] The real-time centralized collection device has an indicator light group fixedly mounted on the collector housing and arranged coplanarly with the data transmission port. The indicator light group indicates whether the storage chip, temperature sensor, humidity sensor and battery are operating, thereby avoiding repeated measurements caused by hardware device failure, saving time and effort.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] This embodiment provides a real-time core temperature and pressure collection device in a drilling sampler, such as Figure 1-4 As shown, the real-time collection device includes a collector housing 1 of integrated hot-melt design installed inside the rope coring drilling sampler and a collection mechanism 2 arranged in the collector housing 1 for real-time collection of core temperature and pressure. The collection mechanism 2 includes a storage chip 21, a temperature sensor 22, a humidity sensor 23 and a battery 24 which are electrically connected in sequence. A protection mechanism 3 is arranged on the collector housing 1;

[0028] The protection mechanism 3 includes a protection shell 31 which is sleeved on the outside of the collector shell 1 and has open through-type design at both ends. An upper end cover 32 with sealing treatment is screwed on one end of the protection shell 31. A tubular protection airbag 33 for sleeved on the collector shell 1 for protection is inserted through the pipe opening at one end of the upper end cover 32 in the protection shell 31. A lower end cover 34 with sealing treatment and fixedly installed with the collector shell 1 is screwed on the end of the protection shell 31 opposite to the upper end cover 32.

[0029] When in use, a detachable protective shell 31 is mounted on the one-piece collector shell 1, and the protective airbag 33 is inserted into the protective shell 31 from one end of the upper end cover 32. The upper end cover 32 is rotated to seal the protective airbag 33 in the protective shell 31, and the lower end cover 34 is rotated from the bottom of the protective shell 31 to screw the collector shell 1 connected to the lower end cover 34 into the center of the protective airbag 33, thereby protecting the collector shell 1 and making it have better protection capabilities in the underground environment to avoid damaging the shell and affecting the internal collection components to collect information.

[0030] It should be noted that the upper end cover 32 is made of a transparent acrylic material, which is convenient for observing the use of the indicator light group 27 and ensuring that the equipment operates normally.

[0031] Furthermore, a retaining ring 35 for limiting the protective airbag 33 is fixedly installed at a position near the lower end cover 34 on the inner wall of the protective shell 31. When in use, the protective airbag 33 is inserted into the protective shell 31 from one end of the upper end cover 32, the bottom is against the retaining ring 35, and then the upper end cover 32 is tightened, so that the protective airbag 33 can be limited from both ends to prevent it from moving and ensure the protection stability.

[0032] Furthermore, a plurality of evenly arranged reflective patches 36 are fixedly mounted on the outer wall of the protective housing 31. When in use, if the protective housing 31 connecting device accidentally detaches from the sampling device and falls to the bottom of the well, the reflective patches 36 can be illuminated to quickly locate the device so as to salvage and obtain information data.

[0033] Example 2

[0034] Different from Example 1, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the real-time centralized collection device also includes a data transmission port 25 electrically connected to the storage chip 21, and the data transmission port 25 is fixedly mounted on the collector housing 1 at an end opposite to the lower end cover 34. When in use, after salvaging, the data transmission port 25 is connected to a computer, mobile phone, or smart tablet via a data cable to quickly obtain information data.

[0035] Furthermore, a rubber plug 26 is inserted into the data transmission port 25. When in use, the rubber plug 26 is inserted into the data transmission port 25 to protect it from dust and foreign matter, and the data transmission port 25 can be connected and used by removing the rubber plug 26.

[0036] Furthermore, the acquisition mechanism 2 also includes an indicator light group 27 consisting of four LED lamp beads electrically connected to the storage chip 21, the temperature sensor 22, the humidity sensor 23 and the battery 24. The indicator light group 27 is fixedly mounted on the collector housing 1 and arranged coplanarly with the data transmission port 25. When in use, the acquisition mechanism 2 is turned on and off by the remote control device. When the LED lamp beads connected to the storage chip 21, the temperature sensor 22, the humidity sensor 23 and the battery 24 are all lit, it is determined that the equipment is operating normally, and the data can be obtained normally by going down the well, avoiding repeated measurements due to equipment failure, saving time and effort.

[0037] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
