Description
Technical field
The utility model relates to a kind of gas and bores the landwaste harvester, relates in particular to a kind of chip sample harvester for mud logging operation under the gas drilling process conditions.
Background technology
Drill bit ravelly ground rock formation landwaste, conventional drilling has the strong drilling fluid of cutting carring ability to take ground out of, circulation of drilling fluid speed is less than 100 m/mins in the well, and circulation of drilling fluid goes out behind the well head under the dither of vibratory screening apparatus, and chip sample is separated and further collection.The lithology identification of chip sample is the basis of drilling geology work, to understand stratum and lithological combination relation, set up the important means of stratigraphic section, the information in kind that obtains from chip sample is that any other method is difficult to replace, so the collection of chip sample becomes important program in the drilling process.
Present increasing gas drilling process application is to probing exploration field, and gas drilling technique is one of effective way of protection reservoir, raising bit speed.Bore under the drilling condition at gas, circulatory mediator is air, diesel engine vent gas, nitrogen or rock gas in the pit shaft, and speed reaches 900 m/mins usually.If the landwaste in the pit shaft is enough little, pit shaft will be taken out of, if larger, then can in the process that falls after rise, be repeated fragmentation, until little of being taken out of pit shaft, so gas drilling will inevitably cause trickle landwaste (the deep-well landwaste is generally dust or dust-like), well logging can't gather the chip sample of dust-like under the high-speed motion.
Therefore, adopting gas to bore under the drilling well situation, the collection of chip sample is being become the problem that those skilled in the art are devoted to consider.
Summary of the invention
The purpose of this utility model is to provide a kind of landwaste harvester that is applied in the gas rig, bores the problem that the landwaste that occurs in the drilling process can't gather to solve gas.
To achieve these goals, gas described in the utility model bores the landwaste harvester and comprises stopple coupon, storage cavity and the cloth bag that connects successively, described stopple coupon porch is provided with the steel disc expansion strip for sampling, the lower end of stopple coupon connects described storage cavity, and the bottom of described storage cavity links to each other with the entrance of cloth bag.
Further, described steel disc expansion strip is the resilient stiff expansion strip, and its termination section is screwed in the stopple coupon inboard, and remainder extends sampling nozzle, and enter in the future with trunk line that stopple coupon is connected in be used for tackling the landwaste of high velocity air under carrying.
Further, be provided with the first valve on the described stopple coupon; Be provided with the second valve between the bottom of described storage cavity and the cloth bag, in order to control the gatherer process of chip sample.
Further, the bottom of described storage cavity has the connecting pipe of one section extension, and described the second valve is arranged on the connecting pipe of this extension.
Further, the bottom of described storage cavity is the cone structure that shrinks gradually, and this cone structure is so that chip sample is easier enters in the cloth bag.
Further, the bottom of described storage cavity and be positioned at cone structure above the chamber wall be provided with view window, to observe the situation that enters of chip sample under the current gas flow.
Further, the lower end of described cloth bag has outlet, is used for the collection of landwaste, and this outlet can be sealed by clip.
Adopted the landwaste harvester of said structure can realize the chip sample collecting work under the well logging process conditions under the gas drilling process conditions, and have safe, stable, easy-to-use characteristic in the chip sample gatherer process, can not have influence on drilling progress because of the fault of device, the chip sample quality and quantity of collection satisfies the industry standard requirement.
