Abstract
The utility model relates to a device for preventing objects from falling into a well and scraping off mud on a drilling tool in petroleum drilling, coal-bed methane drilling, geothermal drilling and water conservancy drilling. The device consists of well shutdown plates, a mud scraping disk box, a rubber mud scraping disk, a controller and a frame, and is characterized by consisting of the well shutdown plates, the mud scraping disk box, the rubber mud scraping disk, the controller and the frame, wherein the two well shutdown plates are positioned in the frame; the middle part of the well shutdown plates is provided with the mud scraping disk box in which the rubber mud scraping disk is arranged; and the controller is arranged between the two ends of the well shutdown plates and the frame, and is one of an electric, hydraulic or pneumatic piston and a spring pull rope. The utility model provides safe, environmentally-friendly and high-efficiency technical equipment for the petroleum drilling, the coal-bed methane drilling, the geothermal drilling and the water conservancy drilling.
Description
Technical field
The utility model relates to and prevents in a kind of oil, coal bed gas, underground heat, the water conservancy drilling well that junk from going into well and scraping the device of mud on the clean drilling tool.
Technical background
In drilling process, the accident that metal objects is fallen in the well happens occasionally, and salvaging or grind these objects often needs for a long time.Yet, utilize present " iron plate Gai Jing " method can not thoroughly do away with this class accident, because iron plate need move apart well head during trip-out and following the boring.In addition, the disc type stripper rubber that uses is installed at present needs the time, causes junk to go into well in this process easily.
Summary of the invention
The utility model has designed below a kind of rotating disk that is installed in rig, can prevent that foreign material from falling into well casing, can finish the anti-junk mud-scraping apparatus of scraping the mud function again.The purpose of this utility model is to realize like this, anti-junk mud-scraping apparatus is made up of closing well plate, mud scraping disc box, vulcanite scraper mud pan, controller, framework, two closing well plates are in the framework, the mid portion of closing well plate has the mud scraping disc box, the vulcanite scraper mud pan is installed in the box, is controller between closing well plate two ends and framework.By the size in the slit of controller control closing well plate opening and closing and unlatching, thereby can realize that anti-junk goes into well, scrapes mud and prevent the function of rubber disc wearing and tearing.Operating principle is as follows: in the controller closed condition, its two closing well plates keep closing, and block the fallen object from the top, make it can not fall in the pit shaft, and the vulcanite scraper mud pan can also realize scraping automatically the mud function; If when not needing to scrape the mud function, adjust controller, just can allow the vulcanite scraper mud pan leave drilling tool.When being lowered to drill bit or large-sized drill collar, controller is transferred to open state, with the closing well plate draw back bigger getting final product.Controller is a kind of in electronic, hydraulic pressure or pneumaticpiston, the spring drag-line.The utility model has thoroughly done away with metal objects and has fallen into class accident in the well, has realized that simultaneously drilling rod scrapes the mud function, for providing the safe environmental protection high efficiency technical equipment in oil, coal bed gas, underground heat, the water conservancy drilling well.

The specific embodiment
Embodiment 1: as shown in the figure, scrape the mud well lid and mainly be made of closing well plate 1 mud scraping disc box 2 vulcanite scraper mud pans 3 compression spring 4 drag-lines 5 and framework 6, during use it is installed in below the rotating disk of rig.Usually, closing well plate 1 is in closed condition under the effect of compression spring 4, and the semi-circular vulcanite scraper mud pan 3 in the mud scraping disc box 2 contacts with drilling tool, in the process of trip-out, and the mud that it can the scraping drilling tool.Simultaneously, closing well plate 1 mud scraping disc box 2 and vulcanite scraper mud pan 3 block the fallen object from the top together, make it can not fall in the pit shaft.If when not needing to scrape the mud function, as long as with drag-line 3 pulling 10mm-20mm, vulcanite scraper mud pan 3 will leave drilling tool, with anti-wear.When being lowered to drill bit, as long as the tension drag-line, all open closing well plate 1.
Claims (3)
1. anti-junk mud-scraping apparatus, be made up of closing well plate, mud scraping disc box, vulcanite scraper mud pan, controller, framework, it is characterized in that: two closing well plates are in the framework, and the mid portion of closing well plate has the mud scraping disc box, the vulcanite scraper mud pan is installed in the box, is controller between closing well plate two ends and framework.
