click Cavaville owns a series of stimulation methods such as fracturing, acidizing, oil well unplugging, oil well chemical water plugging, water injection well profile control and oil displacement, water injection well decompression and augmented injection, water injection well squeezing, etc.
Coil tubing hydraulic jetting fracturing technology
High-speed jet has entered into the perforation to make the pressure higher than the formation fracture pressure, so that the formation has been fractured along the drill way: a long crack has been created along lots of perforations. Fracturing fluids have been bumped into through pipelines, and have been injected into the drill way, while few have entered into other part of the wellbores; the high-speed pumping action can further intensify the separate effect. With the help of the jet flow hydraulic packing, staged fracturing can be achieved. Coil tubing hydraulic jetting fracturing technology is a new kind of stimulation method integrated with perforation, fracturing and separation, with the hydraulic packing function, no need of mechanical packing to achieve staged fracturing. The operation period is short with high efficiency. Even though the annular pressure is lower than the bursting pressure, the formation can still be fractured. The fracturing direction is easy to be controlled.
Oil well chemical water plugging technology
Cavaville has developed different types of oil well chemical water plugging technology, and the major technologies are: 1. Cementing water plugging technology 2. Selecting water based water plugging technology.
Cementing water plugging
The major plugging agents are water based mud, oil based mud, activation cement, and particle cement. Recently, the company has developed the nanoscale particle cement. When the cement has been squeezed into the formation, the cement can enter into the water blocked channel, with higher plugging ability and higher efficiency.
Selecting water based water plugging technology
PP polymer plugging agent is soluble in water but is not soluble in oil. When the plugging agent was injected into the formation, the oil reservoir has been restricted to let out water without influencing the production. The water plugging principle is that amido and carboxyl on partially hydrolysed PP molecule influence the absorption ability of the molecular chain. The principle of the residual residence is that absorbing, gathering and physically plugging.
