Description

A kind of full-automatic degasser

Technical field:

The utility model relates to a kind of full-automatic degasser, is the electronic degasser of full-automatic lifting formula that a kind of petroleum geology compound logging is used, and belongs to petroleum geology well logging technical equipment field.

Background technology:

Will carry out the oil gas analysis to drilling underground rock stratum in the oilfield drilling, mainly be that the oil gas analysis is carried out in the rock stratum of drilling process different depth.Generally all be provided with import (lower position) and export (high position), drilling fluid mud pit square, that storage refluxes at one; Degasser is placed on it; Mud to returning up with drilling fluid in the oilfield drilling carries out online fragmentation, and the oil gas that wherein comprises is deviate from and passed to the instrument room through tracheae and analyze.Present existing oil gas degasser exists following shortcoming and subject matter:

1, degasifying effect is undesirable: drilling fluid all is to be driven underground with drill bit with high-pressure pump; So it is very fast that it returns the spare mobility that comes with drilling fluid; Measure very greatly, existing degasser is because the outlet of broken bucket mud is provided with unreasonablely, and the mud of turnover degassing bucket is few; And asynchronous with the drilling fluid flow velocity, cause can not science the actual conditions of reacting drilling well different depth rock stratum oily accurately.
