Simple process

Oil extraction methods are from the spray oil and mechanical oil, spray oil from underground Food dehydrator layer is due to the higher pressure, the pressure in their own right can make the crude oil gushing from the wellhead way. Mechanical oil pump is to use various types of crude oil from the well to draw, China's oil exploitation by mechanical oil-based. Different geological nature of the oil situation is different with different mechanical mining methods. On the viscosity of less than 50 mPa. Seconds, density less than 0.934 crude oil (called thin oil), usually with conventional mining. On the viscosity of greater than 50 mPa. Seconds, density greater than 0.934 crude oil (called heavy oil), usually with thermal recovery, which uses hot steam stimulation, mixed with light oil and heating oil recovery methods. Liaohe Oilfield, oil equipment is characteristic of the northern winter. Except for a few oil lubrication oil, most of the oil is heavy and extra-heavy oil, heavy crude oil components as much, viscosity and relative density, the crude oil under reservoir conditions hardly flow, can not use conventional methods to extract , to the production and the environment has brought a series of problems. We use oil thermal recovery, dilution, emulsion viscosity of mining.
