Abstract
The invention discloses an oil well cement fluid loss agent and a preparing method thereof. The oil well cement fluid loss agent is prepared from, by weight, 4-4.5 parts of 2-acrylamide-2-methylpropanesulfonic acid, 1-2 parts of N-vinyl pyrrolidone, 4-5 parts of N,N-dimethylacrylamide, 80 parts of water and 0.2 part of an initiator. The preparing method comprises the steps that firstly, 2-acrylamide-2-methylpropanesulfonic acid, N,N-dimethylacrylamide and water are mixed, the solution is poured into a reactor, the reactor is sealed and put into a constant-temperature water bath pot, stirring is carried out, preheating is carried out to reach 30-40 DEG C, and N-vinyl pyrrolidone is added into the solution; then, nitrogen is introduced into the reactor; finally, the initiator is added, the temperature of the water bath pot is increased to 80 DEG C and maintained, a continuous reaction is carried out for 4-8 h at the temperature, and the oil well cement fluid loss agent is obtained. According to the oil well cement fluid loss agent and the preparing method thereof, monomers are reasonably selected, are in a proper proportion and can react with one another to reach the optimal fluid loss reducing effects of salt resistance and high temperature resistance.
Description
Technical field
The present invention relates to oil well cement additive field, particularly relate to a kind of oil-well cement filtrate reducer and preparation thereof
Method.
Background technology
Oil-well cement filtrate reducer is that one can control in cement mortar liquid phase to permeable formation leak-off, thus keeps
The material of the suitable ratio of mud of cement mortar, when oil gas well drilling, along with the increase of the oil gas well drilling degree of depth, shaft bottom
Environment change, the requirement for the fluid loss agent of oil-well cement is more and more higher.Currently used oil well
The primary raw material of cement water reducer has polyvinyl alcohol, hydroxyethyl cellulose, acrylamide/acrylic acid copolymer
Deng, these fluid loss agents generally there are anti-salt, the shortcoming of high-temperature resistance difference.
Summary of the invention
Present invention seek to address that the deficiencies in the prior art, and provide a kind of fall dehydration effect salt good, anti-resistant to elevated temperatures
Fluid loss agent and preparation method thereof.
For achieving the above object, by the following technical solutions: a kind of oil-well cement filtrate reducer, it is special for the present invention
Levy and be, be made up of the raw material of following parts by weight:
As preferably, described initiator is Ammonium persulfate.；
The present invention provides the preparation method of a kind of oil-well cement filtrate reducer, it is characterised in that comprise the following steps:
(1) by 2-acrylamide-2-methylpro panesulfonic acid, N, N dimethyl acrylamide and water are in a reservoir
Mixing；
(2) solution is put in reactor, reactor is sealed, is placed in thermostat water bath stirring, preheating
To 30～40 DEG C, add N-vinylpyridine network alkanone in the solution；
(3) in reactor, nitrogen is led to drive away the oxygen in reactor；
(4) add initiator, make water-bath be warming up to 80 DEG C and be incubated, sustained response 4～8h at this temperature,
Obtain oil-well cement filtrate reducer.
The invention has the beneficial effects as follows: instant component monomer has huge side base, makes fluid loss agent have relatively
Good resistance to elevated temperatures, has the strongest sulfonic group of hydrophilic, ring-type lactam structure, can strengthen fall and lose
The water solublity of water preparation, and Stability Analysis of Structures, the attack of cation is insensitive to external world, makes the anti-salt of fluid loss agent
Property improve, increase resistant to elevated temperatures ability, between monomer, ratio is reasonable, by optimal synthesis condition, permissible
React to each other reach optimal salt tolerant, the fall dehydration effect of high temperature resistance.
