Foreword

All the technical contents in this Part are mandatory. Biological Toxicity for Pollutants from Marine Petroleum Exploration and Exploitation is divided into two parts. — Part 1.Grading — Part 2.Test methods This Part is Part 1. This Part replaces GB 18420.1-2001 Biological Toxicity Grading for Pollutants from Marine Petroleum Exploitation and Exploitation. Compared with GB 18420.1-2001, main changes of this Part are as follows. — Terms and definitions relevant to “Mud” is revised as terms and definitions relevant to “Drilling Fluid” (3.4 and 3.5 of 2001 version; 3.4 and 3.6 of this version); — ADD terms and definitions of "Synthetic-based Drilling Fluid" and "Base Fluid" (3.4.3 and 3.5 of this version); — ADD biological toxicity grading requirements for base fluid and synthetic-based drilling fluid (6.1.1, 6.1.2, 6.2.1 and 6.2.2 of this version); — ADJUST the biological toxicity grading requirements for drill cuttings and produced water (5.3, 6.2 and 6.3 of 2001 version; 6.1.3, 6.1.4 and 6.2.3 of this version). This Part was proposed by State Oceanic Administration. This Part shall be centralized by National Marine standardization Technical Committee (SAC/TC 283). The drafting organizations of this part. South China Sea Branch of State Oceanic Administration, and Guangdong Laboratory Animals Monitoring Institute. Main drafters of this part. Wu Jinxiao, Huang Ren, Zheng Yanjing, Wei Shelin, Zhou Jin, Wang Ying, and Wang Guodong. The previous version replaced by this Part is as follows. — GB 18420.1-2001. Biological toxicity for pollutants from marine petroleum exploration and exploitation – Part 1.Grading

1 Scope

This Part specifies the frequency and limit of biological toxicity test in different sea-areas of some pollutants that are used or generated during the marine petroleum exploration and exploitation operation; and are discharged into the ocean. And it puts forward the requirements to test methods and result judgments of the samples. This Part applies to biological toxicity grading of drilling fluid, base fluid, drilling cuttings, and produced water that are used or generated AND discharged into the ocean, during the marine petroleum exploration and exploitation operation. For those pollutants not defined in this Part, the biological toxicity grading may reference to this Part for the use.

2 Normative references

The articles contained in the following documents have become part of this Part when they are quoted herein. For the dated documents so quoted, all the modifications (excluding corrections) or revisions made thereafter shall not be applicable to this Part. For the undated documents so quoted, the latest editions shall be applicable to this Part. GB/T 18420.2 Biological toxicity for pollutants from marine petroleum exploration and exploitation - Part 2.Test methods

3 Terms and definitions

For the purpose of this Part, the following terms and definitions shall apply. 3.1 Pollutant from marine petroleum exploration and exploitation Any substance that is used or generated AND discharged into the ocean during marine petroleum exploration and exploitation operation; and that may have an impact on the marine ecological environment. 3.2 Biological toxicity grading of pollutants According to the influence degree of pollutants from marine petroleum exploration and exploitation on marine organisms, the different grades that are adopted to divide the biological toxicity of pollutants. 3.3 Operation of marine petroleum exploration and exploitation The operation activities such as marine petroleum exploration, exploitation, production, storage, and pipeline transportation. 3.4 Drilling fluid The circulating fluid that is used in drilling process and that has the effects such as lubrication and cooling drill bit, carrying drill cuttings, balancing formation pressure. It includes water-based drilling fluids, oil-based drilling fluids, and synthetic-based drilling fluids. 3.4.1 Water-based drilling fluid The drilling fluid of which the suspension of solid particles is water soluble - i.e., the solid particles are suspended in water or in salt-water; the oil can be emulsified into water; and the water is in continuous phase. 3.4.2 Oil-based drilling fluid The drilling oil of which the continuous phase is diesel, mineral oil or some other oils that do not contain synthetic substance. 3.4.3 Synthetic-based drilling fluid The drilling oil of which the continuous phase is certain synthetic organic compounds (e.g. plant ester, poly a-olefins, internal olefins, Linear α- olefin, ethyl ether, linear alkylbenzene etc.); or the drilling oil of mixture of these synthetic organic compounds. 3.5 Base fluid The continuous phase in the formula of oil-based drilling fluid or synthetic-based drilling fluid. 3.6 Drill cuttings The debris that is generated from the drilling stratum operation and is discharged with drilling fluids, during the marine petroleum exploration and exploitation. It is divided into water-based drill cutting, oil-based drill cutting, and synthetic-based drill cutting. 3.7 Produced water The water separated from the oil-water mixed fluid that is from the stratum in exploitation of oil reservoir. It includes oil-reservoir water, process water and chemical substances added in oil-water separation. 3.8 Biological toxicity limit The biological toxicity limit that is allowed to be discharged into the sea-area by the pollutants from marine petroleum exploration and exploitation. 3.9 Test frequency During a certain period of time, the number of biological toxicity test of pollutants, from marine petroleum exploration and exploitation, discharged in different sea-areas. 3.10 Biological toxicity test Under the condition, it refers to a test method that pollutants are imposed on organisms, so as to determine the generated toxicity effect of pollutants ON the organisms.

4 Sea-area level

Pollutants from marine petroleum exploration and exploitation shall accord to the levels of dumping sea-area specified by this Part to executive classification standard. Sea-area levels are divided as follows. — Level I sea-area. It includes Liaodong Bay, Bohai Bay, Laizhou Bay, North Bay, the special marine protection sea-areas, and other protected sea-areas designated by ......
