Drilling Mud in Horizontal Directional Crossing Project


Courtesy of

Horizontal Directional Crossing Project has a not long development in the country and even the world. But in recent years, pipeline horizontal directional crossing has been great development, large-scale construction of oil and gas pipelines across the length and across the diameter of the continuous creation of new records. In horizontal directional crossing project, the drilling mud play a very important role, it will directly effect the decision directed through the project.

The high performance of drilling mud in Horizontal Directional Crossing Project

Drilling mud is a very important factor in Horizontal Directional Crossing Project. Drilling mud is generally composed of water , drilling mud additives such as bentonite and dubbed. Drilling mud composition ratio needs to be appropriately adjusted according to the actual situation across the project. If the complex geological conditions , through the larger diameter and length of the drilling mud performance requirements is relatively high , corresponding to take different measures to ensure that the Horizontal Directional Crossing Project was successful.

1. Drilling mud should have the appropriate viscosity and fluidity, stronger ability to carry cuttings to make cuttings in suspension in the bottom of the hole , the flow of drilling mud through the drill cuttings can successfully return to the ground .

2. Drilling mud retaining wall should have a relatively strong effect, can improve the stability of the borehole wall , especially for large diameter is easy to collapse formation , but also because such .

3 .Drilling mud should have a strong lubrication, the return line to provide effective lubrication drag effect , particularly through the length of the longer , adding a lubricant to reduce the coefficient of friction can be reduced back to the drag force of the pipeline.

4 Crossing through different strata and across different stages of construction , adjustment of pressure and flow of drilling mud , through the construction to meet the needs .

KOSUN Solid Control System, whose design, manufacture and production are mainly done by Xi’an KOSUN Machinery Co., Ltd., has found wide application not only in oil drilling and exploration, but also in horizontal directional crossing projects for stage treatment of directional drilling fluids. Its work in the Qiantang River Crossing Project of Hangzhou-Ningbo Gas Pipeline Engineering in China is one of the successes done by KOSUN’s products, whose stability and advanced technologies allowed the project’s completion on schedule and precision of crossing.
As a professional manufacturer of solids control equipment, KOSUN is specializes in designing & manufacturing oilfield shale shaker, drilling mud agitator, mud gun, mud desander, desilter, drilling mud cleaner, drilling fluids decanter centrifuge, mud mixer, centrifugal pump, desilter cone, shearing pump, vertical slurry pump, mud tank, vacuum degasser, vertical cuttings dryer, ignition device, drilling mud system, etc. And it has exported to Russia, Kazakhstan, Egypt, Indonesia, Mexico, Australia, etc. with qualified products & superior services.
