相关成果QJ-625油井水泥***
QJ-625通过产生微气泡均布于水泥浆体系，有效补偿水泥“胶凝失重”和“水化体积减缩”造成压力降，提高水泥环胶结强度。从而有效防止地层中油、气、水外窜。
性能特点：
? QJ-625为棕色粉末，***、无嗅。
? 由发气剂、稳泡剂和降失水剂等原料复合制成。
? 一般加量0.3%～0.6%(BWOC).
? 发气稳定，气泡微小且分布均匀，发气时间可控。
? 对水泥浆稠化时间、流变性、游离水等无不良影响，增压抗压强度明显提高。
? 适用于常规及低比重水泥浆。
? 特别适用于井径极不规则、井径扩大的井眼，深井调整井中的平衡压力固井的压稳防窜、高压油气活跃固井使用。
? 干混可以获是比湿混更理想的膨胀效果。

The agent at a temperature of 95 DEG C, 1000 to 95 DEG C under atmospheric pressure, oil well cement has better drag reduction, greatly improve the mobility of slurry, and to 75 degrees C and 120 degrees of oil well cement in the corresponding conditi*** are good, drag reduction
The agent has certain retarding performance
It is used for oil, gas well cementing engineering, improve water slurry on the mud displacement effect, improving the cementing quality
The agent is a chemical raw materials, carefully selected process conditi*** for synthesis of manufacturing, and its raw materials based on the existing material, simple technological process and easy generalization, production equipment, and strict production control and product testing, product performance and stability, reliable
In the oil drilling cementing engineering used in the agent, can s***e a large amount of foreign exchange, the use of domestic materials, and help to improve the cementing quality, reduced pump pressure, accelerate the speed of well cementing
Related to the outcome of QJ-625 cement swelling agent
QJ-625 by generating micro bubbles uniformly on the cement slurry system, effective compensation" cement cementitious weight loss" and" hydration volume reduction " caused by the pressure drop, improve the cementing strength. In order to effectively prevent the formation of oil, gas, water channeling.
Performance characteristics:
? QJ-625 brown powder, non-toxic, odorless.
? by foaming agent, foam stabilizing agent and filtrate reducer made of composite materials.
? a general increase in volume 0.3% ~ 0.6% ( BWOC ).
Gas bubble? Stability, ***all and uniform distribution, gas controllable time.
? on cement slurry thickening time, rheology, free water and no adverse effect, compressive strength improves ***iously booster.
? suitable for conventional and low density cement slurry.
? is particularly applicable to the borehole diameter is very irregular, borehole diameter enlargement of well, deep well adjusting well balanced pressure cementing pressure stability anti channeling, high pressure oil and gas well cementing using active.
Dry mixed can get wet? Is mixed more ideal expansion effect.
