Abstract

The invention relates to the field of coal mining, and discloses a method and a device for measuring the mass percentage concentration of pulverized coal in coalbed gas well output liquid, so as to solve the technical problem of inaccurate detection of pulverized coal concentration in the prior art. The method includes: determining the coal bed density of the coalbed methane well; obtaining the output fluid of the coalbed methane well at the sampling port of the coalbed methane well; determining the first density of the output fluid; filtering out the coal in the output fluid Powder particles, to obtain a solution containing anions and cations; determine the second density of the solution containing anions and cations; determine the coal of the production liquid based on the coal seam density, the first density and the second density Powder mass percentage. The technical effect that the determined pulverized coal mass percentage is more accurate is achieved.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to a method and a device for measuring the mass percentage concentration of pulverized coal in liquid produced from a coal bed gas well. Background technique [0002] The drainage technology of coalbed methane wells is a very important link in the development of coalbed methane, and it is one of the main factors affecting the production of coalbed methane wells. The entire drainage process of CBM wells is accompanied by the output of pulverized coal. Generally, fine pulverized coal is discharged from the wellbore in the form of a suspension. Excessive accumulation of pulverized coal with medium and coarse particles will cause mechanical failure (pump stuck) and frequent The pump inspection operation will produce large bottom hole pressure fluctuations, which will destroy the continuity of gas, water and pulverized coal flow, thereby affecting the gas production potential and the productiv...
