Description
Technical field
The invention belongs to oilfield stimulation field, be specifically related to a kind of fracturing drag reducer and preparation thereof and application.
Background technology
Fine and close unconventional reservoir has low hole, hypotonic feature, and exploration and development difficulty is relatively big, and most of fine and close Oil/gas Wells need reservoir reconstruction could obtain more satisfactory yield. At present, sending out well stimulation topmost for fine and close unconventional reservoir happy both at home and abroad is drag reduction pressure break, namely utilizes low frictional resistance slippery water fracturing fluid to carry out volume transformation. Slippery water fracturing fluid system is a kind of new fracturing fluid system grown up for fine and close unconventional reservoir transformation. In the state such as the U.S., Canada, the of the fracturing fluid use of slippery water obtains significant economic benefit and instead of traditional gelatinous fracturing fluid and become most popular fracturing fluid.
Slippery water fracturing fluid refers to a kind of fracturing fluid system adding the additive such as a certain amount of proppant and minimal amount of drag reducer, demulsification cleanup agent, clay stabilizer, antibacterial in clear water. Compare traditional gel fracture liquid system, slippery water fracturing fluid has great advantage in the fine and close unconventional reservoir of exploitation, as slippery water fracturing fluid considerably reduces the gel injury to stratum and crack: traditional gel fracture liquid system uses the gel of higher concentration, the residue of these gels and the filter cake produced in fracturing process can block stratum and reduce fracture condudtiviy, and containing only there being the additives such as a small amount of drag reducer in slippery water fracturing fluid, and it is prone to the row of returning, greatly reduce stratum and Damage to Fractures, thus being conducive to improving yield;And slippery water fracturing fluid is less costly: chemical addition agent and the consumption of proppant in drag reduction water are less, can save construction cost 40%��60%, make many reservoirs originally not having business extraction value just can be developed; In addition use slippery water fracturing fluid can produce the fracture network that the higher volume of complexity is bigger: when this is to have relatively low viscosity and construction due to drag reduction glassware for drinking water to pump into speed higher, what the raising of crack complexity and volume added reservoir effectively increases production volume so that yield increases; What is more important due in drag reduction water additive level few, comparatively clean, be therefore easier to recycle, it is possible to save a large amount of valuable freshwater resources.
Therefore, in slippery water fracturing fluid, the application of the use of additive, particularly drag reducer and demand also get more and more.
