CHAPTER 2 PLATFORM LAYOUT
2.1 General Provisions
2.1.1 The platform shall be designed bad on the design criteria of oil (gas) field development engineering, the process design of well drilling,completion and work-over, and/or the overall process flow design for the production of oil(gas) field as well as the overall layout of production installations of oil(gas) development engineering (called overall layout design hereunder), to determine the orientation and dimensions of the platform, and reasonably to arrange production area, utility area and living quarters, so as to ensure, in a cost effective and reasonable manner, the safety of production operations, personnel life and property.
2.1.2 Before starting up of the overall layout and process design, the platform operator shall provide engineering contractor with design criteria as listed in Article 2 of this Chapter,and the materials on the environmental conditions of the a area where the platform is located shall be made available by a qualified agency.
Reoccurrence of environmental conditions ud in engineering work shall be determined by the operator as a result of the technical and economical evaluation on the life of the field, importance of the platform and reliability of materials on the environmental conditions, etc. and shall be written into the 〈Safety analysis report for offshore oil (gas) production facilities 〉as required by Article 21,Section 2 of尚志一中〈The Provision on the Survey of Offshore Oil and Gas Production Facilities海南省简称〉.
2.2 Overall Layout and Process Design
例假血块2.2.1 Design criteria
The main design criteria for an oil (gas) development engineering are as follows:
2.2.1.1 Geographical location of the oil (gas) field;
2.2.1.2 Rervoir characteristics and its development plan;
2.2.1.3 Physical properties and chemical composition of rervoir fluids;
2.2.1.4 Drilling plan, mode of well completion and method of work-over;
梧桐树三更雨
2.2.1.5 Way of production, wellhead flowing pressure, shut-in pressure and wellhead fluid temperature, gas/oil ratio, water cut, production pressure drops;
2.2.1.6 Oil field production life, year by year output of oil, gas and water as well as water injection rates;
2.2.1.7 Number of wells and maximum single well daily output of oil, gas and water;
2.2.1.8 Environmental conditions
(1) Environmental conditions required in platform engineering mean all that which can impact the strength元旦灯谜大全及答案、stability、construction and installation work as well as operations of the platform. The environmental conditions which may give significant impact to the platform include but not limited to: hydrometeorology, earthquake, attaching organism, abottom scouring, erosion & glacial wearing and a floor geomorphology & engineering geology.
(2) Original materials ud for determining the design environmental conditions shall be reliable, successive and reprentative. The method ud for deriving the design environmental conditions shall be generally recognized.
2.2.2 Drilling and work-over process designs
丽江老君山If a platform drilling unit and work-over unit be ud to perform drilling and work-over operations, an optimized drilling and work-over process design shall be worked out bad on the rervoir data, well spacing and the requirements for the layout of drilling and work-over equipment,and tho as specified in 2.2.1.1, 2.2.1.2, 2.2.1.4, 2.2.1.6 of this Chapter for the field concerned.

2.2.4 General layout of the oil/gas development engineering.
The field development engineering plan shall be screened out and optimized to work out a general layout drawing for all the field development engineering installations.
2.3 Main Items for the Platform Layout and Hazardous Area Classification
2.3.1 Principles for platform layout
The following principles shall be followed to determine the layout of drilling, work-over equipment and/or oil (gas) production equipment, utility and living facilities on deck, so as to determine the deck size:
2.3.1.1 To satisfy the needs of safety, fire prevention, fire extinguishing, escape and life-saving;
2.3.1.2 To satisfy the needs of production operations;
2.3.1.3 To satisfy the needs of maintenance and accident handling;
2.3.1.4 To satisfy the requirements of structural rationality;
