Semi-submersible drilling platform with Corrosion Resistant Alloy Pipes excellent performance and a larger anti-wave variable loads and drilling in the deeper waters. At that time only a few countries in the world can build, and expensive. In order to adapt to China's actual conditions designed continental shelf of semi-submersible drilling platform, three units of the designer a large collection of hydrological and meteorological data, and through in-depth practical investigation crossover drilling of five kinds  of rigorous screening program was finally officially confirmed rectangular semi-submersible drilling platform solution. The main performance parameters; water depth of 35 to 200 m, the maximum drilling depth of 6000 m.

Bottom-known drilling rig instrumentation drilling barge Intelligent Drilling Robots or barge for rivers and bays and other shallow waters less than 30m. Bottom-founded platforms have two hulls, also known as work on the hull deck, cabin and equipment placement life, by means of opening the tail gun drilling boom; the lower part is a mat, and its main function is to support the role of submarine ballast and used as a drilling Foundation. Between two hulls connected by a support structure. Such drilling rigs to water within the mat after reaching the job site to the bottom. Therefore, from the stability and structure, the operation depth is not only limited, but also by submarine base (flat and firm level) constraints. Therefore, the slow development of this platform. However, shallow waters extending into the sea along the coast of Bohai Sea, China Shengli Oilfield, Dagang Oilfield and Liaohe Oilfield, large tidal range and seabed slope small, for the development of petroleum resources in such shallow water area, bottom-founded platforms still greater development in the future . The early 1980s, people began to pay attention to oil development in the Arctic waters, design, construction polar bottom-platform also attracted the interest of ocean Sucker Rod Pump Unit Controller  engineering. After sitting at the end there are several platform for the polar regions, it ballasted sit on the seabed, and then fill in the central platform of sand to prevent slippage platform, complete the drilling can be discharged ballast floating, and move to another a well location.

Most deep-water oil and gas field production Casing and tubing collar Gas tight connection systems will be under water, usually the ambient temperature is low, and deepwater oil and gas wells and may be HPHT. If oil and gas wells located in the high latitudes of the arctic zone or hot waters near the equator, this performance and with the degree of drilling rigs and offshore vessels are demanding. In addition to the ship function of echo each other, Offshore Oil Engineering (12.58, -0.11, -0.87%) in the last five years, the introduction of 17 sets of deep-sea underwater robot (108.060, 3.98, 3.82%) also extends these deepwater engineering vessel function. They will be in deep water oil and gas development, to come up with their own "killer", and "deep water fleet," along with each other vigorously to promote the production and maximize the benefits of play.
CNOOC deepwater drilling technology, equipment and ability has been recognized by international peers. 2015, in the Norwegian North Sea operations "USS Enterprise" won the first quarter Statoil rig Sealed bearing roller reamer comprehensive assessment of the first assessment, was named "the best platform for the quarter." This is the "USS Enterprise" since last September following the second award. This is the seventh China Sea oil rigs Statoil won the "best platform" title.

Lifting operations should implement special Sucker rods with molded guide command. Commanders should be holding a valid certificate rigging command, wearing distinctive Sucker rod pump unit controller identification command (eg: armband, vests, etc.), in a safe and appropriate location rigging crane drivers who can see clearly. When the commander and crane drivers and poorly should be added the command staff middle transfer signal Casing and tubing collar Gas tight connection commanding lifting. Lifting process, no person shall be hanging objects remain below or through, hanging objects can not stop people moving radius.

Including the completion of each Drill robot well before drilling engineering, drilling engineering and completion operations in three stages. Each stage of a project there are a number Oilfield robot for safety platform operation of construction process. The main steps generally include: fixed wells, roads survey, foundation construction, installation derrick, moving, installation of equipment, a drilling,Sucker rod pump unit controller secondary drilling, drilling, tripping, for drill, drill, completion, electrical measurement , casing, cementing operation and so on.

In geological work, the use of drilling equipment Roller Reamers Drilling Manufacturers to drill into the ground smaller diameter greater depth columnar hole, known as drilling. Drilling diameter and depth sizes, depending on the purpose and mineral drilling depth of burial. Drilling for oil, natural gas and groundwater drilling diameters Hydraulic mechanical double acting drilling jar are larger. The main functions are: ① get underground kind of information that take core drilling core taken from drilling, mine heart, debris, liquid-like, gas-like and so on. ② as geophysical logging channel, get all kinds of rock Mandrel sub for drilling jar layers geophysical field data. ③ observation as an artificial channel aquifers hydrogeological dynamics. ④ used for exploration, mining combine, develop groundwater, oil and gas, geothermal drilling.

Drilling is a systematic project, is a multi-disciplinary, multi IB down hole String Stabilizer trades using a variety of equipment, tools, materials carried out joint operations. While it is more closely co-ordinated program, multi-link ring interlocking continuous operation. The whole process of construction has considerable complexity. Including the completion of each well before drilling engineering, drilling engineering and completion L8013Cr Pup joint manufacturers operations in three stages. Each stage of a project there are a number of construction process. The main steps generally include: fixed wells, roads survey, foundation construction, installation derrick, moving,Spiral Grooved drill collar stock installation of equipment, a drilling, secondary drilling, drilling, tripping, for drill, drill, completion, electrical measurement , casing, cementing operation and so on.
