Abstract
The present invention discloses a filtrate reducer having a good filtrate reducing effect, and a preparation method thereof, wherein an organic matter, a cationic surfactant, an organic amine salt, lactam, a protonation agent, a transition metal nickel salt and water are subjected to heating, stirring, suction filtration, washing, drying and grinding to obtain the filtrate reducer. According to the present invention, the filtrate reducer provides the significant filtrate reducing effect in the drilling fluid adopting the palm oil as the base liquid, and can meet the base requirement of the drilling fluid on the filtrate reducer.
Description
Technical field
The present invention relates to oil base drilling fluid fluid loss agent field, be related specifically in plam oil fluid loss agent with filtrate reducing effect and preparation method thereof.
Background technology
In drilling process, geologic condition becomes more complicated, and high temperature, high pressure, high salt ground environment make the dehydration of drilling fluid, rheological property etc. control to become difficulty.Through the exploitations of more than 100 years these to be easy to explore the prospective oil of productive formation fewer and feweri, people have to sight to turn to the oil in some bad grounds of land and deep water ocean.In ocean deepwater drilling, mainly face the poor stability of seabed shale, drilling fluid consumption be large, well cleaning is difficult, the complicated difficult problem such as rheological instability, formation-parting pressure window narrows that shallow layer gas easily forms drilling fluid under gas hydrate, low temperature, the petroleum exploration and development technology of routine can not the needs of deep water marine drilling.Also more and more stricter to the requirement of drilling fluid in drilling process, can the quality of property of drilling fluid directly has influence on drilling well safely, rapidly and economically, and a kind of good drilling fluid system should have good filtrate loss controllability and film-forming properties.
The leak-off of drilling fluid refers at a certain temperature, and when in pit shaft, drilling liquid pressure is greater than formation pore pressure, the freedom in drilling fluid is diffused in stratum mutually goes.Enter into freely meeting of stratum and bring a series of problem, especially the stratum that mud shale content is high is easy to cause caving in of the borehole wall, but also the pollution of reservoir can be caused, the wettability reversal on stratum can be caused after some tensio-active agents in drilling fluid enter stratum, very large difficulty is brought, so the filter loss controlling drilling fluid is particularly important to crude oil production.
The present invention is directed to plam oil and do the development of oil base drilling fluid base fluid, it has significant filtrate reducing effect in plam oil, can meet plam oil as the basic demand for fluid loss agent during drilling fluid base fluid.
