Grout through above-mentioned prepared only needs to add activator and other required conventional admixture of cement slurry property in use, like retardant and fluid loss agent etc., injects the down-hole immediately after adjusting performance such as thickening time.
But above-mentioned storing liquid cement is applicable to the well cementation and the workover treatment of various hole conditions; The well cementation, the workover treatment that are specially adapted to the less well cementation of cement slurry volume, workover treatment (like the small hole well cementation) and can't go up conventional cementing equipment; Like offshore platform, remote districts and beach sea well cementing operation etc.; The well cementation in these areas and mixing equipment do not have placement space or are difficult to arrive at platform, utilize transportation means (tugboat and/or tank car etc.) commonly used that the grout of fluidization is transported to the scene, add after certain additive adjusts the thickening time; Utilize the facility of platform or tugboat to pump in the well, thereby realize well cementing operation.But table two is the contrast of the present invention's storage of liquids grout and traditional cementing slurry.
But the contrast of table 2 the present invention storage of liquids grout and traditional cementing slurry
Project The tradition cementing slurry But storing liquid grout
Requirement to equipment The Mud mixer that band circulation is puddled, 2 cement pump trucks, displacement slot, cement storage tank, air compressor machine, dashpot, particle collector, batch-handling mixer, power pack The LCP groove of the warehousing and transportation facilities of LCP/ admixture, 2 triplex pumps, displacement slot, 2 25bbl
Operations area m 2 74 35
Area occupied m 2 43 21
Weight kg 26000 16000
Total expense 100％ 38.60％
Can know by last table, but the present invention's storing liquid grout is compared aspect a lot of with traditional well cementing operation with well cementation significant raising has all been arranged.But storing liquid cement has solved the problem of mixing ash at the scene, has realized that premix mixes, and has avoided interrupting, expect because of defeated ash the speed of puddling that factor such as storehouse fluctuation causes and the fluctuation of rate of pumping, has improved well cementation efficient.Mix owing to realized premix, but the dosage of each composition material in the storing liquid cement is accurate, puddles evenly fully, cement slurry density can reach accurate control.But adopt the storing liquid well cementing of cement, do not need complicacy, expensive air-pressure equipment, puddle equipment etc. and just can accomplish well cementing operation, and can reduce operator, reduce schedule of operation, reduction operations area.
