Abstract
The oriental white oak glue powder fracturing fluid densifier includes expansion preventer, draining aid, demulsifying agent, sterilizer, filter loss reducing agent and degluing agent as well as characterized oriental white oak glue powder, borate as crosslinking agent and alkali regulator. The present invention is used in fracturing process of oil field, and can reduce the operation cost, raise fracturing effect and expand the range of fracturing operation.
Description
The present invention relates to the chemical assistant that a kind of oil field is used, especially for the oriented white oak glue powder as fracturing liquor densifier of down-hole construction.
" oilfield chemistry " first phase in 1997 discloses a kind of water-base gel fracturing fluid fenugreek gum viscosifying agent (being fenugreek gum), discloses a kind of organic titanium PC-500 crosslinked hydroxypropyl guar gel fracturing fluid gelatinizer (being guanidine glue) again with printing the third phase in 1999; Fenugreek gum is that annual herb plant Trigonella foenum-graecum seed endosperm processes, though have physicochemical property preferably as fracturing fluid gelatinizer, does not satisfy the needs of oil field compression fracture construction owing to yield poorly; Guanidine glue also processes for herbaceous plant melon beans seed endosperm, and its output and physicochemical property all can satisfy the construction needs, but since resource mainly abroad, production cost is higher, has limited the scope of field use.
The objective of the invention is:, can adapt to the oriented white oak glue powder as fracturing liquor densifier of all kinds of oil well applications for oil field compression fracture construction provides a kind of good physical and chemical properties, wide material sources, production cost low.
The objective of the invention is to realize: a kind of oriented white oak glue powder as fracturing liquor densifier by following measure, comprise expansion-resisting agent, cleanup additive, emulsion splitter, sterilant, fluid loss agent, gel breaker etc., it is characterized in that also including Mongolian oak chestnut rubber powder, borate (linking agent) and alkaline conditioner, back both and the former ratio is respectively 3-5: 1 (weight ratio).
Purpose of the present invention can also realize by following measure: borate (linking agent) can be borax, also can be organic boron (OCB); Alkaline conditioner can be yellow soda ash, also can be sodium bicarbonate.
Raw material sources of the present invention is extensive, easy to process, good physical and chemical properties, production cost are low, is used for oil field compression fracture construction can obviously reduction operating cost, improves measure effect, enlarges the range of choice of pressing crack construction.
Mongolian oak in oriented white oak glue powder as fracturing liquor densifier chestnut rubber powder is a seed of taking from the bitter Li beans of Wild jujube in Taihang Mountain Area wild plant, processes through removing the peel, pulverize, sieve etc., and particle diameter is below 200 orders, and its major ingredient is gala-mannosans, and molecular formula is [C

n, structural formula is:
The compound method of oriented white oak glue powder as fracturing liquor densifier is: the Mongolian oak grain rubber powder aqueous solution of 0.3-0.5% is stirred expansion-resisting agent that the back adds convention amount, cleanup additive, emulsion splitter, sterilant, fluid loss agent, gel breaker etc., add then and be equivalent to Mongolian oak grain rubber powder 3-5: the borax of 1 (weight ratio) or organic boron (OCB) are as linking agent, add and be equivalent to Mongolian oak grain rubber powder 3-5: the yellow soda ash of 1 (weight ratio) or be equivalent to Mongolian oak grain rubber powder 20-30: the sodium bicarbonate of 1 (weight ratio) is as conditioning agent, and the liquid after the preparation just can be used for pressing crack construction through swelling; The mechanism of crosslinking of oriented white oak glue powder as fracturing liquor densifier is that borate combines with cis hydroxyl groups, that is:
Claims (5)
1, a kind of oriented white oak glue powder as fracturing liquor densifier, comprise expansion-resisting agent, cleanup additive, emulsion splitter, sterilant, fluid loss agent, gel breaker etc., it is characterized in that: also include Mongolian oak chestnut rubber powder, borate (linking agent) and alkaline conditioner, back both and the former ratio is respectively 3-5: 1 (weight ratio).
2, fracturing fluid gelatinizer according to claim 1 is characterized in that: borate (linking agent) can be borax.
