[0061] Example 1

[0062] like Figure 1 As shown, this embodiment provides an evaluation method for an offshore platform produced water treatment process, comprising the following steps:

[0063] 1) In combination with the special working conditions and produced water treatment index requirements of offshore platforms (offshore platforms have limited space and load-bearing capacity, requiring compact and efficient treatment equipment, that is, to be able to achieve the required treatment indicators under the conditions of small footprint, low space occupancy, and light operating weight), an offshore platform produced water treatment evaluation index system is constructed, including three first-level evaluation indicators: equipment index A, economic index B, and low-carbon index C. Among them, equipment index A includes two second-level evaluation indicators: weight index A1 and floor space index A2; economic index B includes two second-level evaluation indicators: cost per ton of water treatment B1 and cost per barrel of oil water treatment B2; low-carbon index C includes two second-level evaluation indicators: energy consumption per ton of water treatment C1 and carbon emissions per ton of water treatment C2. The constructed offshore platform produced water treatment evaluation index system is shown in Table 1 below:

[0064] Table 1: Offshore platform production water treatment evaluation index system

[0065]

[0066]

[0067] Specifically, the calculation formula of the weight index A1 is:

[0068] F W =W / Q L (1)

[0069] Among them, F W is the secondary evaluation index parameter of weight index A1; W is the operating weight of the equipment or skid during operation, in tons; Q L is the sewage flow rate, in t / h.

[0070] The calculation formula for land occupation index A2 is:

[0071] F A =A / Q L (2)

[0072] Among them, F A It is the secondary evaluation index parameter of the floor space indicator A2; A is the floor space of the equipment or skid and the maintenance access, the unit is m 2 .

[0073] The calculation formula for the water treatment cost per ton B1 (yuan / ton) is:

[0074] C E =C / Q t (3)

[0075] Among them, C E is the secondary evaluation indicator parameter of the ton water treatment cost B1; C is the total cost, in RMB, including equipment or skid investment, deck fees, and life cycle operating costs and maintenance costs. Among them, operating costs include electricity costs, chemicals costs, and auxiliary media costs, and maintenance costs include replacement costs of internal parts and filter media, etc., considering only water treatment consumption; Q t The total amount of sewage treated is in tons, and the water volume in the entire life cycle is calculated based on the allocated production.

[0076] The calculation formula for the water treatment cost B2 (yuan / ton) per barrel of oil is:

[0077] C O =0.137C E / (1-f w ) (4)

[0078] Among them, C O is the secondary evaluation index parameter of the barrel oil water treatment cost B2; 0.137 is the barrel oil weight, in tons; f w It is the comprehensive water content of the oil field, in %.

[0079] The calculation formula for the energy consumption C1 (degrees / ton) per ton of water treatment is:

[0080] E=P / Q L (5)

[0081] Among them, E is the secondary evaluation index parameter of energy consumption per ton of water treatment C1, which only considers electricity consumption; P is the equipment power, the unit is kWh.

[0082] Carbon emissions per ton of water treated (KgCO 2-eq The calculation formula of t) is:

[0083] m co2 =(P×EF E +Q CH ×EF CH / Q L (6)

[0084] Among them, m co2 EF is the secondary evaluation index parameter of carbon emission C2 per ton of water treatment; E is China's electricity emission factor, in kg CO 2-eq / kWh;Q CH is the flow rate of the agent, in kg / h; EF CH is the chemical agent emission factor, in kg CO 2-eq / kg.

[0085] 2) According to the basic process and applicable objects similar to the produced water treatment process of the offshore platform to be evaluated, the standard produced water treatment process of an offshore platform is selected as the evaluation standard.

[0086] Specifically, based on the requirements for produced water treatment of offshore platforms in different sea areas, a standard produced water treatment process was summarized and summarized as shown in Table 2 below. The produced water treatment process of the offshore platform to be evaluated was compared with the standard produced water treatment processes of the Bohai Sea platform, the South China Sea platform, the Bohai Sea floating facility, and the South China Sea floating facility in Table 2. The standard produced water treatment process of an offshore platform with similar basic processes and applicable objects to the produced water treatment process of the offshore platform to be evaluated was selected as the evaluation standard.

[0087] Table 2: Standard treatment process for produced water from offshore platforms in various sea areas

[0088]

[0089] 3) According to the special requirements of the offshore platform to be evaluated, determine the weights of each first-level evaluation index and second-level evaluation index in the offshore platform production water treatment evaluation index system.

[0090] For example: if the available area of ​​an offshore platform is small, the weight of the "occupancy index" will be set higher; if the offshore platform can increase or decrease less weight, the weight of the "weight index" will be set higher; in addition, some offshore platforms may pay more attention to the "cost of treating a ton of water" or "energy consumption per ton of water treatment" or "carbon emissions per ton of water treatment", so the weight of the corresponding index will be set higher.

[0091] 4) Based on the basic data of the process equipment and the selected evaluation criteria, determine the index of each secondary evaluation indicator in the produced water treatment process to be evaluated on the offshore platform, specifically:

[0092] 4.1) Based on the basic data of the process equipment, calculate the secondary evaluation index parameters for the standard produced water treatment process and the offshore platform produced water treatment process to be evaluated.

[0093] Specifically, the basic data of process equipment include the data required in the above formulas (1) to (6), such as the operating weight W of the equipment or skid during operation, the sewage flow rate Q L , the floor space of the equipment or skid and maintenance passage A, etc.

[0094] 4.2) Compare the secondary evaluation index parameters of the standard produced water treatment process with the secondary index parameters corresponding to the produced water treatment process to be evaluated on the offshore platform to obtain the index of each secondary evaluation index in the produced water treatment process to be evaluated on the offshore platform.

[0095] Specifically, the index of each secondary indicator evaluation of the standard production water treatment process is 1 (dimensionless). The index of the secondary indicator evaluation is shown in Table 3 below:

[0097] Index Weight index a1 Land occupation index a2 Ton of water treatment cost index b1 Barrel of oil water treatment cost index b2 Energy consumption index per ton of water treated c1 Carbon emission index per ton of water treated c2

[0098] 5) Based on the index of each secondary evaluation indicator and the weight of each secondary evaluation indicator in the produced water treatment process to be evaluated of the offshore platform, the parameters of each primary evaluation indicator in the produced water treatment process to be evaluated of the offshore platform are determined, and then the comprehensive evaluation parameters of the produced water treatment process to be evaluated of the offshore platform are determined, and the evaluation results of the produced water treatment process to be evaluated of the offshore platform are obtained, which are specifically:

[0099] 5.1) Determine the parameters of each primary evaluation indicator in the produced water treatment process to be evaluated of the offshore platform based on the index of each secondary evaluation indicator and the weight of each secondary evaluation indicator in the produced water treatment process to be evaluated of the offshore platform.

[0100] Specifically, the first-level evaluation index parameter A of the equipment index is:

[0108] Among them, Z1 is the weight of energy consumption per ton of water treatment; Z2 is the weight of carbon emissions per ton of water treatment.

[0109] 5.2) Determine the comprehensive evaluation parameters of the produced water treatment process of the offshore platform to be evaluated based on the parameters of each first-level evaluation indicator and the weight of each first-level evaluation indicator in the produced water treatment process to be evaluated of the offshore platform, and then determine the evaluation results of the produced water treatment process to be evaluated of the offshore platform.

[0110] Specifically, the evaluation results of the offshore platform's production water treatment process to be evaluated include recommended processes or improvement suggestions, wherein when the comprehensive evaluation parameter is greater than 1, the offshore platform's production water treatment process to be evaluated is superior to the corresponding production water standard treatment process, and the higher the score, the more advanced it is. More specifically, if the offshore platform's production water treatment process to be evaluated is the production water treatment process to be evaluated of an offshore platform to be built, then when the comprehensive evaluation parameter is greater than 1, the offshore platform will be constructed according to the production water treatment process to be evaluated; otherwise, the offshore platform will be constructed according to the corresponding production water standard treatment process; if the offshore platform's production water treatment process to be evaluated is the production water treatment process to be evaluated of an existing offshore platform, then when the comprehensive evaluation parameter is greater than 1, the offshore platform will be improved according to the production water treatment process to be evaluated; otherwise, the offshore platform will be improved according to the corresponding production water standard treatment process.
