Description
Technical Field
The invention relates to the technical field of fluid mineral exploitation, in particular to solid particles capable of being adhered and application thereof.
Background
At present, oil and gas well sand control is divided into mechanical sand control and chemical sand control, and the chemical sand control is divided into sand fixing liquid sand control and sand coating sand control. The mechanical sand control is only suitable for the shaft rule of the oil and gas well, and the mechanical sieve tube can be put into the oil and gas well at the specified position. The sand fixing liquid is used for preventing sand from invading into a liquid stratum, so that serious stratum damage is caused. The coated sand is relatively flexible to the application in oil and gas wells, and avoids reservoir damage.
However, the bonding strength and the validity period of the coated sand are generally not high for low-temperature oil and gas recovery wells at present. The normal oil production operation of the oil and gas well is seriously influenced by the sand produced from the stratum or the sand returned and discharged by the propping agent. Formation sand flows out of the formation with oil, gas and water, with several serious effects: 1. the outflow of stratum sand causes the original support structure of the stratum to collapse, and the oil-gas well is buried and scrapped. 2. The outflow of the stratum sand leads to the landfill of oil extraction and gas production pipelines and the sand blockage of oil well pumps, and seriously influences the oil extraction and gas production progress of oil and gas wells. 3. The outflow of the formation sand along with the high-speed fluid seriously abrades the oil extraction gas production pipeline and the valve, so that the leakage of the high-pressure fluid is caused, and serious safety accidents are caused. 4. A large amount of stratum sand flows out, so that a large amount of oil-containing sludge sand is generated in an oil-gas well, and serious environmental pollution is caused. Besides causing the serious pollution, the proppant back-spitting sand also causes failure of fracturing production increasing measures, and causes a great deal of waste of manpower and material resources.
Accordingly, oil and gas well sand control becomes an indispensable operation measure of the sand production well.
Therefore, how to improve the sand control effect of the oil and gas well is a problem which needs to be solved urgently by the technical personnel in the field.
