Small solid-liquid separation device suitable for well site and solid-liquid separation method

Abstract

The invention discloses a small solid-liquid separation device suitable for a well site and a separation method. The device comprises a groove-shaped screening box body, a motor base is installed on the screening box body, a vibration motor is installed on the motor base, a detachable cover plate is installed on the top of the screening box body, and a feeding opening is formed in the cover plate; and a screen is horizontally installed in a screening box body, a gap is reserved between the front end of the screen and the side wall of the screening box body, the bottom of the screening box body inclines downwards from front to back, a discharging opening is formed in the position, opposite to the gap, of the front end of the bottom of the screening box body, and a liquid discharging opening is formed in the end of the inclined bottom of the screening box body. The screening box body is supported by more than three supporting columns, and damping springs are arranged between the supporting columns and the screening box body. The solid-liquid separation method disclosed by the invention can effectively separate the rock debris and the drilling fluid (mud), and is good in separation effect and high in speed.

Description

technical field [0001] The invention belongs to the field of petroleum drilling, and in particular relates to a small solid-liquid separation device and a solid-liquid separation method suitable for use in well sites in the field. Background technique [0002] Debris geological analysis is an important basis for identifying formation lithology, judging formation horizons, and discovering and evaluating oil and gas layers. With the continuous development of drilling technology and faster drilling speed, the existing cuttings solid-liquid separation device can no longer meet the needs, and there are mainly the following disadvantages: the separated cuttings samples cannot achieve Orderly and real-time separation and collection according to the drilling depth, the quality of such geological samples cannot be guaranteed; the bulky size does not adapt to the installation environment of the well site; the integrated design is not convenient for transportation and installation; the...
