RC Rods Remet Drill Rods for Reverse Circulation Drilling

This series reverse circulation pipes can increase penetration in lost-circulation formation, reduce driling fluid consumption, protect reservoir stratum and save the cost of other consumption tools. ln additional, the pipes can be worked in two direction circulation drling ways to control the well driling. By reverse circulation method to ki the we the heawy mud can be transferred directly to the bottom of well, no periodic circulaton and save time.

Functions and Features

The internal structure is very simple with components of high rigidity, thus ensuring long life and easy maintenance of the hammer.
Equipped with bits designed with patent. Simply by replacing the drill bit, the same hammer can drill holes of different sizes ensuring that the sample is not contaminated.

Based on previous experience with ordinary hammers, combined with the features of reverse circulation hammer, optimized internal structure and ideal energy transfer, thus ensuring the series of hammers drilling with fast, smooth, and continuous sampling.
The collection tube adopts an integrative design and can be replaced without disassembling the hammer. With carburizing treatment, it has good abrasive resistance.
In different conditions such as loose soil, hard rock, and plenty of water, sampling can be done well.

Product Description

High-pressure air is transported into somewhere of the well along with air pip, via mixer, to inject the high-pressure air into the pipe with liquid, due tothe density of mixed liquor lower than the fushing liquor therefore a differential pressure occurred between pipe and sample tube that to make themixed air and liquid flow up fleetly by the fluid column pressure and take the rock debris or powder out to the ground from bottom of the holecontinuousiv. By this driling method wil provide with advantages ike hich penetration rate. quality pore-forming and fewer hole collapse during drilling in loose formation.
