Drilling shell "KROT"
Everyone knows that the golden times were passing, when oil was scooped up by buckets from shallow pits or pumped from not deep wells in the ground. To put it mildly, the depths of prey increased. Oil-bearing horizons are located deeper and deeper. And together with the increase in the depths of occurrence, the depths of drilling increase. Accordingly, the cost of drilling wells is increasing. In this section, we will discuss the two most important issues.
1. Cost of drilling.
2. Drilling cost.
Deep drilling means if well depth more than kilometer.
The cost of the mobile drilling rig for drilling on water or superficial drilling on solid minerals, or drilling for construction (geological studying, etc.) begins from 10 000 US dollars for second-hand and comes to an end with half a million dollars. And it together with the fancy chassis, the change house and laboratory. And the price of the drilling rig, self-propelled, for example - begins with this sum.
We will not talk badly about Chinese drilling rigs, or talk well about Canadian or American drilling rigs, but a drilling rig that can drill a well more than three kilometers deep cannot cost less than $ 15 million in full. To put it mildly, after 3.5 kilometers of drilling, with the prices for drilling rigs, such miracles begin, and since the cost of the gas logging station, the price of the express laboratory or cost of the drill bit program is also composed of millions of dollars, then the small extracting company has nothing else to involve service companies.
There are several criteria on the basis of which the price of the daily rental rate of drilling equipment is formed and, accordingly, the cost of drilling a well:
- The daily cost of reserving equipment and tools in the warehouse of the contractor;
- The daily cost of renting drilling equipment and drilling tools on the road;
- The daily cost of renting drilling equipment and drilling tools passing through customs clearance;
- The daily cost of renting drilling equipment and drilling tools on the customer's premises;
- The daily cost of renting drilling equipment and drilling tools in idle time at the drilling site;
- The daily cost of renting drilling equipment and drilling tools in operation.
The price of drilling oil and gas wells is a difficult question ... is not it?
Now, after reading, if someone is not too lazy, the above, we want to offer you to save a lot of money on drilling wells. How much is much? You can count yourself. Exclude from the list of equipment for drilling the cost or rent of the derrick, the cost or lease of drill pipes and a crazy chisel program. In addition, you can free a lot of loafers, leading the tower support to shine, with their sweatshirts. After you turn off these costs, you can see that the list has "lost weight" by millions of dollars.
Ask, "What about without it?!" "Without this, drilling is not possible!!!" Maybe!!!
Use to drill USDS!
Universal self-propelled drilling shell "Krot" (USDS "KROT").
I foresee the mass of questions... Also it is ready for them to answer. Below, not to paint advantage of USDS with the simple description which will hardly present a full picture I offer answers to the arrived and arriving questions from our Clients and Partners.
What represents USDS?
USDS – a universal self-propelled boring shell for well-drilling of different function.
Whether patents are taken out on USDS?
Yes. Patents for invention and utility model have been obtained. Also applications were sent for the protection of intellectual property abroad.
What are the analogues of USDS in well construction?
In the implementation of patent searches of domestic and foreign analogs is not found.
What is the difference between the USDS and other methods?
Drilling pipes are not used to drill the USDS, and there is therefore no need for a drilling rig. The axial load on the drilling tool and the rotation of the drilling tool is created by the USDS itself.
An example, currently used method: Rotary drilling of oil wells is one of the popular methods. The chisel passing deep into the soil rocks rotates together with the drill pipes. The torque of such a system, first of all, depends on the resistance of the rocks that come across on the way. Turbine drilling of oil wells is performed at the expense of the installation, in which the bit interacts with the turbine. In rotation, the plant is driven by a fluid flow that circulates under high pressure through a system of stators and rotors.
The well construction cycle includes: preparatory works; installation of towers and equipment; preparation for drilling; the drilling process; casing and casing; Opening of the reservoir and testing for oil and gas inflow. In the course of the preparatory work, they choose a site for drilling; build an access road, supply electricity, water supply and communication systems. If the terrain is uneven, then plan a site.
In our case, when using the USDS for drilling, there is no need to: erect a tower, lay an access road, supply the power supply system, and plan the site.
What are the dimensions and mass of the USDS?
The dimensions and mass of the USDS are regulated by the depth and diameter of the well being built and can reach a weight of 50 kg to 10 tons.
