In PCOC, amount of the oil, gas and water wells are over 50,000 and they are widely distributed, difficult to manage.
It was responsible for the whole process of oil, gas and water production from wellbore to joint station.
Production management system, with oil and gas basic production unit process control as a core, was focused in single well, pipeline and station (tank) and etc. basic production unit process control and management, which provided data to middle terminal and post terminal. 2.1.1 Digital management of well site ① Data acquisition: Real-time data acquisition including oil well loading and displacement, pumping unit three-phase electrical parameters, pipeline pressure, pressure and quantity of water injection well, pressure of water injection valve, water withdrawal quantity of the source well and water pump three-phase electrical parameters. ② Monitoring: Intelligent video server. ③ Remote-control: Remote pumping unit start-up and shut down, remote control of water injection well, intelligent control of source well.
Digital management of station ① Data acquisition: Pressure and temperature of influent oil, liquid level of oil storage (water) tank, outlet and inlet pressure of oil transportation (water injection) pump, pressure and temperature of effluent oil, detection of flammable gas in station.
Technicians in operating zones, stations and wells got released from the daily production running and maintenance, thus made up of professional group to solve the key technical problems.

Engineering problem can use of TRIZ professional language to describe, and can use of TRIZ tools to resolve.
Figure 3: Flow chart about design process Case study JYS - Z electric brush type filter used in the process of industrial wastewater treatment, steel cinder water, power plant process and cooling water, paper processes, chemical production process and irrigation systems, to filter the hard particle from 3,500 to 130 microns diameter in water to ensure the security and reliable operation of the system.
As shown in figure 4, raw water run into the filter body, through the coarse mesh and the fine mesh, and then go through centrifugal axis to decompose wastewater water and clear water.
Functional requirements-FR1: run into raw water FR2: decompose raw water FR3: filtrate clear water FR4: recover clear water FR5: recover sewage water Design parameters-DP1: inlet pipe DP2: coarse mesh DP3: centrifugal axis DP4: steel wire brush DP5: fine mesh DP6: clear water recycling pipe DP7: wastewater recycling equipment Constraint conditions-C1: to filter the hard particle from 3,500 to 130 microns diameter in water C2: to simple structure (consider cost requirements) Figure 4:Working principle diagram of brush type filter AD design matrix: DP1 DP2 DP3 DP4 DP5 DP6 DP7 FR1 1 0 0 0 0 0 0 FR2 0 0 1 0 0 0 0 FR3 0 1 1 1 1 0 0 FR4 0 1 1 1 1 1 0 FR5 0 0 1 1 1 0 1 3) Make sure the design parameters matrix According to problems analysis, in order to translate from the AD design matrix to parameters matrix, determining main design parameters is significant.
Right now, the main design parameters which produce the problem will remove, but FR3 of filtering clear water affected

It existed with water soluble and alcohol soluble.
In order to eliminate water soluble tannin, first oak barrel soaked in water for 2~3 weeks.
Then, pour out the water from the barrel, make barrel mouth downward, and make use of pipe to access into steam heating until out of condensed water is colorless (about 30 minutes).
Finaly, rinse with water and dry with air.
First, the mildew barrels were washed with water, then immersed 10~15 days to make use of 60%~70% alcohol, poured out alcohol, then washed and cleaned with 40~50℃ hot water until tasteless; or ignited sulfur rope inner ladle crane stainless steel keg for 24 hours in the oak barrel, rinse with water, made barrel mouth downward and treated with steam for 30 minutes, then cleaned with water.

Although these studies have a certain guiding significance for the practical engineering, but there is a relative lack of the study for the dual derrick on deep-water drilling rigs.
Introduction Compared with other offshore platforms, drilling ships have features such as the general transport ship shapes, flexible moving, simple berthing and so on, the water plane area is bigger than other platforms and the variation of variable weight (impermeable casing, drill pipe, drilling water, mud materials, cement and other drilling equipment weight) has lesser effect on the ship's draft.
Now in the respect of dynamic characteristics analysis for dual derrick, mainly depends on professional soft wares to proceed dynamic analysis, approximatively simulate the practical working conditions then check the stability of dual derricks by calculation as well as dynamics experimental research, which includes field experimental method and the scaling model experimental.
Looking medium scale jack-up platform as objects of study, K.G.Grenda [5] investigated dynamic response of derrick under the wave loads, the results shown that in the waters at a depth of more than 50m, wave load dynamic amplification factor had a potentially important effect.
However, there is a relative lack of the study for the dual derrick on deep-water drilling rigs.

Current, wave generation device is the hot spots of marine scientific research, there are many types of these devices, such as “Nodding duck”, Oscillating water column ,pushing and pendulum ,wave gathering and energy storage ,Oscillating buoy, Valve and so on.
The core modules include user interface module (ADAMS/View), Solver(ADAMS/ Solver),Professional post-processing modules( ADAMS / Post Processor ),it has a good interactive graphical interface and powerful solver and high-performance post-processing features[5,6].

The results of experiments show that this solution can effectively control the contamination risk during the disposal progress, and avoid the metastatic spread of the contaminated soil. 1 Introduction Contaminated sites are an important kind of environmental pollution sources, which includes factories, mines, gas stations, landfills and waste dumps, etc. because the emissions, leakage and scatter of the pollution pollutes the soil, air, water and other environmental media, and continually threaten the ecological safety and human health.
If the cover exist pollution risks, it should be delineated to prevent the spread of pollutants, and disposed by the professional pollution disposal company.
