In recent years, with the oil, natural gas development and utilization , now the domestic and foreign Petroleum and natural gas reserves of energy, development and use of life is worrying. All the countries in the energy-saving emission reduction, the development of new energy to the martial arts. Among them, the shale gas as a new energy, the exploration, development and utilization has been put on the agenda.
Shale gas mainly located in the dark mud shale or high carbon shale, shale gas is subject to adsorption or free state exists in the mudstone, mudstone, shale and high carbon powder sandy rocks in the dissection of natural gas, the various stages of natural gas generated in the body
Shale gas development has the advantages of long service life and the exploitation of long production cycle — most of gas shale wide distribution, big thickness, and generally contain gas, shale gas wells can make long-term stable gas production. But the shale gas reservoir with low permeability, mining is difficult. With the world energy consumption rising, non conventional energy sources including shale gas. American and Canada and other countries have achieved commercial development of shale gas.
However, the shale gas development model, principle and basically also is oil, natural gas, coal bed gas development relatively similar. Is also an exploration, drilling, collection, utilization of the process. The same is by drilling in mud solid control system, shale shaker vacuum degasser desander, desilter, drilling fluid decanter centrifuge main solid control equipment five purification and mud tank, mud agitator and other auxiliary solids control equipment and other auxiliary equipment under the action of drilling, complete shale gas drilling.
Brightway with many years engaged in oil and gas drilling mud, non excavation engineering, the development of coal-bed gas, shield, river dredging field of solid control system R & D and production which is now in the development of drilling shale gas field supporting solid control, accumulated certain experience, with superb technology and a high level of production.
