Abstract
The utility model relates to a rock debris sampler for foam drilling fluid. The rock debris sampler comprises a box cover, a foam drilling fluid sampling inlet, a liquid waste discharge port, a rock debris and foam separating device, a sampler box body and a bended connector. The rock debris sampler main body is a cuboid box body with fixed volume and is provided with the box cover. The foam drilling fluid sampling inlet is arranged above the right side face of the cuboid box body and is connected with the bended connector and the rock debris and foam separating device. A liquid waste discharge port is arranged at the bottom of the right side face of the cuboid box body. The box body is a foam drilling fluid buffer tank, the half of a top cover of the foam drilling fluid buffer tank can be freely opened and closed, and the base can be separated from the box body above. A foam defoamer is contained in the foam drilling fluid buffer tank for eliminating foam and preventing foam from overflowing. A valve is arranged in front of the sampler to control the flow of foam, air and rock debris mixture entering into the sampler.
Description
Technical field
The utility model relates to a kind of petroleum drilling well logging down-hole drilling fluids landwaste harvester, the particularly a kind of foam drilling fluid landwaste sampler that can use in the air foam well-drilling well logging.
Background technology
At present, air foam well-drilling is advanced wellbore construction technology, system infusion potpourri replaces mud drilling liquid about 97% pressurized air and 3% because air foam well-drilling adopts, it is big to have flow, the characteristics that flow velocity is fast, therefore, in real boring, can bring out the landwaste of drill bit fragmentation back to ground faster, and can overcome a small amount of water outlet in stratum, go out the wet goods problem, has the mechanical drill speed of effective raising, shorten drilling period, save the advantage of drilling cost, but air bores the gas detection logging for on-the-spot geological logging work, work such as sieve residue log have all proposed new challenge and requirement.Bore construction period at air, site mud logging generally uses gauze bag to finish the collection of landwaste, fast when in use boring owing to air, return out landwaste and all be floury, fine particulate, the landwaste diameter is many less than 2mm, and landwaste all is adsorbed on the foam, is difficult to landwaste is separated from foam, this quantity that has caused landwaste to be fished for is few, can not satisfy the geology sampling requirement.Simultaneously, will close the open flow valve when bringing bottoms up and change gauze bag, it is discontinuous to cause landwaste to gather, and uses inconvenience, very easily damages.
Goal of the invention
The purpose of this utility model provides a kind of foam drilling fluid landwaste sampler, overcomes the defective of existence of the prior art, guarantees the continuity of landwaste collection and the authenticity of landwaste material object, and the quantity that landwaste is fished for, quality have satisfied the consumption of every analytical test.
Summary of the invention
The utility model purpose is achieved in that foam drilling fluid landwaste sampler, and this landwaste sampler is made up of case lid, foam drilling fluid injection port, waste liquid escape hole, landwaste foam tripping device, sampler casing, elbow connection.This landwaste sampler main body is the rectangular parallelepiped casing of a fixed volume, be provided with a case lid above it, one foam drilling fluid injection port is arranged above rectangular parallelepiped casing right flank, and interconnect between elbow connection and the landwaste foam tripping device, the bottom of rectangular parallelepiped casing right flank is provided with a waste liquid escape hole.Casing is the foam drilling fluid surge tank, and half can freely open top ends of cans and close, and base can separate with top casing.The sampler core apparatus is the adjustable trestle filter screen, internal screen has 60 orders, 80 orders, 100 orders, 120 orders, 5 kinds of models of 150 orders, can change the different meshes filter screen as required, filter screen outside design one tripping device, one stent support is arranged between at the bottom of tripping device and the case, and bottom, sampler left side is equipped with valve.
The utility model principle of work: in the foam drilling fluid surge tank, contain the foam defoamer, be used to eliminate foam, avoid foam excessive, control foam by valve before advancing sampler, air and landwaste potpourri advance the sampler flow, work as foam, after air and landwaste potpourri entered sampler, the landwaste that utilizes filter screen will be adsorbed on the foam was separated, when getting the landwaste sample, open valve B, valve-off A takes out the filter screen among the tripping device A, pour out landwaste, gather when wrapping landwaste down, open valve A again, valve-off B, take out the filter screen among the tripping device B, pour out landwaste, recycle, guaranteed that landwaste fishes for continuity.Waste liquid can be opened bottom, left side valve and discharge more for a long time in sampler.
The beneficial effects of the utility model are: foam drilling fluid landwaste sampler has filled up domestic in air foam well-drilling well logging process, the blank of landwaste quantity quality and collection continuity aspect, improve authenticity, the reliability of landwaste material object greatly, guaranteed landwaste section coincidence rate.Foam drilling fluid landwaste sample-taker device can be applied to the air foam well-drilling field, plays the effect that escorts for sieve residue log.This sampler is easy to use quick, has not only alleviated site mud logging personnel's labour intensity, and it is few and fish for the problem of uncontinuity to have solved landwaste quantity, for the Party A in time provides first-hand data in kind.Therefore, foam drilling fluid landwaste sampler has significant popularizing application prospect in the application facet of sieve residue log.
