Description

A kind of oil and gas wells in oil fields well cementation is with micro foam agent and preparation method thereof
Technical field
The invention belongs to oil cementing technology field, particularly a kind of oil and gas wells in oil fields well cementation is with micro foam agent and preparation method thereof.
Background technology
The foam cementing concrete slurry is a kind of extremely-low density cementing slurry, can be applied to the well cementing operation of packing low pressure leakiness stratum, shallow gas pay and long interval isolation well.In casing and cementing, use and have following advantage:
1. low density, least density can reach 0.72g/cm 32. help improving the mud displacement efficiency, this is because foam slurry has higher viscosity, helps the not runny mud of displacement; 3. has relative high compression strength (under the equal densities condition); 4. owing to have compressibility, therefore can compensate cementitious grout weightlessness, help anti-gas channeling and improve interface cementing strength; 5. under high-temperature and high-pressure conditions, conventional relatively cement stone has better toughness; 6. have lower rate of permeation and dehydration, suitable thixotropic property can adapt to the cementing requirement of complicated well; 7. relatively low operating cost, more conventional low-density cement mortar cost reduces about 1/3rd.
The inflation method of foam cementing concrete slurry mainly contains two kinds of methods at present:
(1) uses chemical agent attack in cementing slurry to produce nitrogen, add other admixture such as suds-stabilizing agent etc., form a kind of uniform and stable foamed cement.The shortcoming of this method is that chemical agent uses kind many, and foaming agent is mixed and requires height, the bad control of the process of getting angry.
(2) mechanical aeration foam cementing concrete slurry.U.S. Halliburton Company is devoted to machinery always annotates the research of nitrogen foam slurry cementing technology and improves work, has developed corresponding admixture, computer control system and supporting site construction technology technology.Foam slurry is made up of clean slurry, nitrogen, suds-stabilizing agent and grout treatment agent.During site operation, with the clean slurry of the mixing water preparation that contains various admixtures, form foam slurry through nitrogen pump nitrogen injection in clean slurry by cementing truck, the size of annotating the nitrogen amount according to the cement slurry density of Site Design by computer controlled automatic.The main drawback of this method is a complex equipments, and cost is high, and construction technology is numerous and diverse.
The used common rosin thermopolymer air of construction industry directly adds cementing slurry, and the subject matter of existence is: grout cured body ultimate compression strength is had tangible attenuating effect, and foam size is big, and stability is bad, is unfavorable for being pumped into oil gas well down-hole; High temperature resistant property is poor; The on-the-spot preparation of liquid prod foam slurry difficulty.
Because the long-term exploitation of fld; Most of hydrocarbon zone has been in pressure state in debt; In the oil gas well cementing operation process, usually can miss, be badly in need of novel foam cementing concrete slurry additive and correlation technique, form low density leak-proof leak-stopping well cementing mortar architecture.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art; The object of the present invention is to provide the well cementation of a kind of oil and gas wells in oil fields with micro foam agent and preparation method thereof, set up foam exquisiteness, good stability, blending process is simple, overall performance is good novel extremely-low density microbubble well cementing mortar architecture with this.

The 3rd step; Adding the tri-isopropanolamine of 2.6 weight parts and the high temperature resistance combinations-of surfactants of 1 weight part in the solution after the second step saponification reaction under 80 ℃; Stir 0.5h; Evenly gained synthetic product water cut in back is 20-27%, i.e. micro foam agent work in-process, and wherein said high temperature resistance combinations-of surfactants is 1: 1 nonionogenic tenside OP-10 of weight ratio and nonionogenic tenside SP-80;
The 4th step, micro foam agent work in-process cooling back and lithium bentonite are pulverized by weight 1: 35 mixed, cross 120 mesh sieves, promptly get the oil and gas wells in oil fields well cementation and use micro foam agent.
