Description of the development:
()
In nastoyascheee being investigated, and then sporadically, the state of the atmosphere and soil in the areas of industrial waste storage. Monitoring the depth distribution of contaminants is not made and their impact on the geological environment is not evaluated. This is explained by several reasons, first and foremost - the lack of effective ways and means of geo-environmental monitoring. The method consists in the fact that in the study area, according to the accepted scheme, mobile handheld complex (BEAK), consisting of a two-column drilling system capacity of 3.4 kW electric drill, drilling tool based alloy drill pipe D-16T, a set screw, electric and the compressor is drilled to a depth of wells ekorazvedochnye 30-60m. In sedimentary rocks upper section (3-7m depth) hole drilled out a screw diameter of 60-70 mm to the level of bedrock and make cased this site, after performing with the help of special equipment inspection of the borehole walls and sampling at intervals of 1 m. Then continue drilling to a depth in the basic rocks, but with a diameter of 30-32 mm evacuating fines removal breeding, and in the case of high humidity rock purge or flush with the media feed through the central channel of the drill string. Cased wells on this site do not produce. Perform sampling of the borehole walls and inspection. To this end, the following equipment is designed, which is part of BEAK. Apparatus for inspection of the borehole walls disposed therein comprising a television receiver with a lens frame and having one end rigidly fixed on the housing of the television tube, and the other frame part mounted cone with a smooth surface. At the bottom of the conical mirror placed a light source, such as a ring suspension. Through link (cable - cable) is transmitting equipment in the well due to the adoptive node, for example a computer monitor mounted on the surface. The device operates as follows. Suspended on the cable - the cable television receiver with a frame, a mirror and a light source is lowered into the wellbore to a predetermined depth, and include a light source. Borehole wall is illuminated. Panoramic image of the borehole wall falls on the mirror surface of the cone, fixed on the frame, and is reflected through the lens enters the picture tube, where it is converted into a television signal and communication lines fed to monitor the receiving node. The result is a three-dimensional spatial image of the borehole wall. Apparatus for sampling from sawmills wellbore comprises a casing disposed in the wellbore to the bottom of which is fixed rigidly to the cutter actuator. To lower the power actuator is attached Spacer-return mechanism comprising a reversible drive shaft is installed pressing rubber tire with a rim in contact with the outer surface of the return-Spacing screw disposed in a threaded bushing while connecting with the reversing drive actuator. At the side of the housing, on the outer side thereof is formed on the cutter clamp with an opening connected to a vacuum channel formed within the housing. On the retainer coaxially mounted vacuum channel probopriёmnaya tube within which the part is placed a removable filter retainer. The device is suspended in the well on the cable - cable. The device operates as follows. On the cable-rope it is lowered into the well to the desired depth and a voltage is applied to the actuator. In this nachinet rotate. Include spacers-return mechanism. Bidirectional drive shaft comes into rotation, and fixed on the shaft clamping wheel rim makes its rubber spacers rotate - return the screw in the threaded sleeve. By rotating the screw moves linearly toward the borehole wall, or vice versa, depending on the direction of rotation of the rotary shaft and feeds the cutter to the wall, or returns to its original position. At the same time include the establishment on the surface of the vacuum pump and rock particles formed by the destruction of the walls of the mill hole sucked into probopriёmnuyu tube is attached to the holder. Further promotion of rock particles, their penetration into the vacuum channel prevents the removable filter, and they accumulate in probopriёmnoy tube. On completion of sampling the entire device, together with samples of rock stands out on the surface. Laser caliper for measuring the geometrical characteristics of a borehole. Caliper is composed of a cylindrical body dumbbell shape made of an optically transparent resin material (e.g., polyamide resin or plexiglass) in which the cable for attachment to a ring, and for transmitting information from a well - an electric cable connecting the measuring head with an electronic caliper unit calculates and displays the borehole diameter. Lower body for better passage through the borehole and has a weighted cone-shaped. In both parts of the body are wide optical transparent surface. Out of them, for example, eight laser beams - the top four and bottom, arranged in a horizontal plane at an angle of 90 degrees centigrade to each other (crosswise) and the vertical plane - forming an angle with the axis of caliper measurements determining the coefficient B / C . The middle part of the body is the caliper measurement of the unit and recruited from round, optically transparent plates interconnected opaque Adhesive composition. As a result, a light ray entering into the narrow face of the plate unit are not transferred to the neighboring and the plate thus transmits the light rays exactly in horizontal direction, i.e., perpedikulyarno axis caliper and its image. To restrict the direction of light rays in the horizontal plane (azimuth) in the caliper housing between each pair of upper and lower laser beams - holds eight vertical slots filled with opaque compound. The result is a light-optical system is deflected directly from the borehole wall reflection laser beam emanating from the light spot in the photodetecting device. The device operates as follows. The laser beam, for example, getting on the sidewall of the well, it forms a light spot, which is due to the uneven surface of the side wall of the borehole pereotrazhaet laser beams in all directions. Those which are perpendicular to the axis of caliper in a vertical plane and passing through its center in a horizontal plane, entering through the optical system CCD-channels in the central opening photodetectors carry information about the distance to the borehole walls on all four mutually perpendicular directions. After reading this data and transmitting it to the surface by cable included laser beams, and the measurement cycle is repeated. Mobile drilling and analytical complex to minimize the cost of the study of the geological environment in the context of environmental pressure while increasing the quality of information received.
