Core sampler with controlled cooling water

Abstract

The invention relates to a core sampler with controlled cooling water. The core sampler is an apparatus for drilling a core sample, and belongs to the technical field of a petroleum geology apparatus. The core sampler with controlled cooling water controls the on-off of a water seal cooling system through arranging a normally-closed electric water valve and controls the operation of a sampling motor and the normally-closed electric water valve through arranging an alternating current contactor controlled by a button switch. Once the operation state of the sampling motor is controlled, the operation state of the normally-closed electric water valve can be controlled at the same time so as to switch on and switch off a cooling water source of the water seal cooling system and completely overcome the phenomena that the cooling water of the core sampler transversely flows on the operation spot. The invention is beneficial to improving the operation environment with convenient operation and reducing the development cost of petroleum geology exploration, saves a large amount of water resources at the same time, and has simple structure, strong practicability, obvious energy-saving and emission reduction and economic effect.

Description

technical field [0001] The invention relates to a rock core sampling machine with controllable cooling water. The rock core sampling machine is an instrument for drilling rock core samples and belongs to the technical field of petroleum geological instruments. Background technique [0002] In petroleum geological exploration and development, it is necessary to conduct various experimental tests on formation parameters. In order to complete these experiments, it is first necessary to use a core sampling machine to drill samples of various specifications on the core. [0003] The core sampling machine currently used wraps a water-sealed cooling system around the drill bit connected to the sampling motor. The water-sealed cooling system is directly connected to the cooling water source through a pipeline. Whether it is sample loading, sample loading, or adjustment, the cooling water is always on during the whole work process, and the cooling water flows across the work site, e...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing water-sealed cooling system of the core sampling machine is not equipped with a mechanism to control the opening and closing of the cooling water, which not only brings inconvenience to the operator, but also wastes a lot of water resources. A core sampling machine with controllable cooling water, the cooling water is only connected when the sampling motor is working, which not only helps to improve the working environment, facilitates operation, but also saves a lot of water resources
