Technical field
A kind of continuous jarring formula horizontal well the present invention relates to oil and gas industry horizontal well drilling send drill tools.
Background technology
In oil and gas industry, horizontal well can improve well yield and oil recovery factor, reduce development and production cost,
So horizontal well technology is widely used in various Reservoir Developments, significant economic effect is achieved.Horizontal Well Drilling at present
Well technology is widely popularized as the routine techniques of Reservoir Development.Horizontal well technology needs to use large torque multistage horse
Reach, controllable bent joint, tapered stabilizer, hydraulic thruster, efficient PDC drill bit, large quantities of advanced undergrounds such as MWD and LWD instruments
Tool.However the country can not show a candle to external maturation for the technology of horizontal well development, many instruments and tool all also rely on foreign countries
It provides.
The definition of horizontal well extends a substantial distance for every wellbore in oil reservoir, and the well that hole angle reaches 85 ° or more claims
For horizontal well.The core of so horizontal well is how to extend a substantial distance in oil reservoir, i.e., how to extend horizontal section length.Root
The increase with horizontal section length is known that according to the knowledge of drill string mechanics, and the frictional resistance of horizontal section wellbore and drill string is continuous
Increase, which results in horizontal segment drill strings to be sent into difficulty, and bit pressure is consumed by horizontal segment frictional resistance, can not effectively pass to leading portion
Drill bit, can not creep into, and seriously constrain the development of horizontal well technology.How domestic and international drilling company is to overcome net horizontal section to rub
