Abstract
The invention discloses an oilfield drilling accelerant, consisting of the following components, by weight percent, 5-10% of glycol, 5-10% of tributyl phosphate, 5-15% of sulfonated caster oil, 5-10% of fatty alcohol-polyoxyethylene ether, 10-20% of polyglycerol and the balance of water. The oilfield drilling accelerant provided by the invention is friendly to the environment, overcomes the problem of environmental pollution caused by a fact that the past similar products contain oils, and has a stronger capability of preventing bit balling, a good interfacial activity and a better lubricating capacity.
Description
Technical field
The present invention relates to a kind of oil drilling speed-raising agent, belong to petroleum drilling engineering chemical agent technical field.
Background technology
Drilling speed is directly connected to the cost of oil/gas drilling, and improve rate of penetration is one of target of oil/gas drilling operation pursuit always.The approach that improves drilling speed has 3 kinds: the one, and development of new fast drilling fluid technology; The 2nd, design high efficiency drill, optimization drilling tool structure; The 3rd, use the drilling well optimization technique.At present, normal optimization design with novel fast drilling drilling fluid and high efficiency drill combines the raising drilling speed.Most important progress is to have researched and developed the PDC drill bit in the optimization design of high efficiency drill, and polishing gear wheel PDC drill bit occurred.When the PDC drill bit is combined with the sludge shale formation with oil base, synthetic base drilling fluid, because oil base or synthetic base drilling fluid can reduce moment of torsion, weakens drill string and adhere to, prevent bit balling, keep wellbore stability, improved drilling speed.But the oils compound concentration that adds surpasses 10%, easily causes environmental pollution and its application is restricted.When the PDC drill bit is combined with water-base drilling fluid, when particularly boring the deep layer mud shale stratum, though do not cause environmental pollution, but exist slump in, bit balling, bit freezing, drilling speed to wait slowly problem, can significantly improve drilling speed though add subsequently oiliness compound, but easily enrichment and contaminate environment are so its application also is restricted.For this reason, in the urgent need to research and development environment-friendly type creep into fast drilling liquid technology, wherein most critical be develop have good compatibleness, biodegradable speed-raising agent.
