Abstract
The invention relates to the field of petroleum drilling engineering and especially relates to cement slurry for petroleum drilling. The cement slurry utilizes cement as a main agent and comprises, by mass, 120-140 parts of cement, 8-12 parts of an antifoaming agent, 10-15 parts of a stabilizing agent, 5-10 parts of an organic polymer and 180-200 parts of water. Through the above formula, the cement slurry can improve cement mortar adhesion by times, has very excellent impermeability, crack resistance, impact resistance, high/low temperature resistance and base resistance and belongs to a nontoxic and harmless environment-friendly product which does not produce pollution.
Description
Technical field
The present invention relates to petroleum drilling engineering field, particularly a kind of petroleum drilling grout.
Background technology
Grout is the working fluid used in well cementation, and the function of grout is well cementation.Well cementing operation is injected grout by sleeve pipe to the annular space of the borehole wall and sleeve pipe and allow on it to return to certain altitude, and grout becomes Behavior of Hardened Cement Paste subsequently by the borehole wall and casing cement.
In petroleum drilling engineering, along with going deep into of exploratory development, drilling depth is deepened, and needs the stratum of sealing more complicated.Such as its medium and deep limestone of Tarim Basin, layered suture hole, dolomite ground are grown, and formation pore pressure is low, and drilling well and well cementation are easily missed; dolomite seam hole type interval reservoir protection requires high; leak stopping difficulty is large, is difficult to carry out effective shutoff to it, cannot meets conventional cementing execution conditions.In addition, enter dark under sleeve pipe, bottom temperature is high, and cement strength is easily decayed.
The grout of current use takes drift pearl to add that micro-silicon is formulated mostly; with drift pearl as main lightening material; micro-silicon is as packing material; this system have density variable range large, there is the low and early strength advantages of higher of satisfactory stability, mobility and certain thixotropy, fluid loss, can effectively prevent from missing and protection to hydrocarbon zone.But for well depth, bottomhole wellbore pressure is high, be not suitable with deep well pressure requirement.
Summary of the invention
It is strong that the technical issues that need to address of the present invention are to provide a kind of cohesive force, the grout of good impact resistance.
For solving above-mentioned technical problem, a kind of grout of the present invention is host with cement, comprises according to the mass fraction: cement 120-140 part, defoamer 8-12 part, stablizer 10-15 part, organic polymer 5-10 part, water 180-200 part.
Further, described defoamer is the one in organo-siloxane, polyethers, phenylethyl alcohol oleic acid ester.
Further, described stablizer is the one in epoxy ester, N.F,USP MANNITOL, phosphorous acid ester.
Further, described organic polymer is one or more in formaldehyde polyvinyl acetal, ether of cellulose, fiber.
Sample after above-mentioned formula, grout of the present invention can significantly improve the cohesive force of sand-cement slurry; There is very excellent impermeability, splitting resistance, shock resistance; High-low temperature resistant, alkaline resistance properties is good; Nontoxic, harmless, pollution-free, genus environmentfriendly products.
