[0046] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0047] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied in the field of drilling engineering technology.

[0048] Research has found that people are unable to evaluate and analyze risk accidents in the drilling process during actual drilling operations. Usually, only after an accident or risk occurs and is dealt with in a drilling project can the actual situation and cost of the accident or risk be analyzed and summarized. It is impossible to analyze and compare unhandled accidents or risks, and determine the cost. It is impossible to accurately manage the risks of drilling projects, which leads to low accuracy in risk determination.

[0049] Moreover, in the existing technology, statistics and analysis can usually only be performed after the accident is handled, resulting in serious information lag. There is also a lack of unified standards and references when analyzing and evaluating the economic losses of accidents, making it impossible to perform statistical analysis and comparison on many accidents, and it is difficult to use it to estimate unhandled accidents.

[0050] Based on this, the embodiments of the present application provide a risk management method, device and electronic equipment for drilling projects, which realize the cost management of all risk characteristics of the entire drilling project during the current target operation process, can improve the accuracy of risk management of drilling projects, and greatly improve the accuracy of risk control, thereby providing more effective safety protection for drilling projects.

[0051] See also Figure 1 , Figure 1 This is one of the flowcharts of a risk management method for a drilling project provided in an embodiment of the present application. Figure 1 As shown in the figure, the risk management method for drilling engineering provided by the embodiment of the present application includes the following steps:

[0052] S101. Based on the historical disposal costs of various historical accidents in any historical operation process of the drilling project and the historical disposal indicators of each of the historical accidents, determine the historical standard element disposal costs in the historical operation process.

[0053] In this step, the embodiment provided in this application first defines various parameters in the drilling project, wherein:

[0054] The historical operation process / current target operation process W is used to characterize the process of drilling engineering construction operations and is a prerequisite for the occurrence of safety accidents.

[0055] Accident A is used to characterize the safety accidents that may occur in the operation process W and represents a specific safety accident.

[0056] The disposal process D is used to characterize the on-site disposal plan when dealing with accident event A.

[0057] Cause investigation F is used to represent the investigation of accident A after the accident occurs.

[0058] Risk event R is used to characterize the possible risk of causing accident A and the results of cause investigation F.

[0059] Safety investment (preset risk prevention cost) I is used to represent the preventive safety investment made for known risk events R to avoid accident A.

[0060] The operation process type g is used to characterize the result set of classifying the specific operation process detail collection during the operation process W. The operation process type in the embodiment provided in this application includes but is not limited to multiple process steps such as drilling equipment transportation process and drilling process.

[0061] Accident type c is used to characterize the result set of classifying the specific safety accident collection during the accident A process.

[0062] Risk feature k is used to characterize the result set of feature classification of risk event collection in the process of risk event R.

[0063] The target accident probability p is used to characterize the probability relationship between the risk input cost and the disposal cost obtained through calculation during the risk event R.

[0064] The risk feature weight w is used to characterize the influence coefficient of risk feature k on the target accident probability p during the risk event R.

[0065] Disposal indicator j is a set of quantifiable indicators used to characterize the on-site disposal plan in the disposal process D.

[0066] The disposal cost d is used to represent the actual cost amount incurred in the disposal process D corresponding to the disposal indicator j set.

[0067] The historical standard element disposal cost s is used to represent the unit quantity cost amount calculated corresponding to the disposal indicator j and the disposal cost d in the disposal process D.

[0068] The target preset disposal cost f is used to represent the estimated disposal cost amount calculated by corresponding disposal indicator j and historical standard element disposal cost s in the disposal process D.

[0069] The preset risk prevention cost o is used to represent the preventive risk cost for risk feature k in the safety investment process I.

[0070] The optimal risk input cost e is used to represent the optimal risk input cost obtained by solving the model in the safety investment process I.

[0071] The preset risk acceptance r is used to characterize the proportional parameter when calculating the optimal solution of risk input cost.

[0072] The embodiment provided in this application assumes that the historical disposal cost of historical accidents is represented by d, and the historical disposal index of historical accidents is represented by j, which has:

[0073]

[0074] Here, t is used to represent the number of historical accidents, and s is used to represent the historical standard factor disposal cost in the historical operation process.

[0075] Among them, in the actual production process, the impact of different historical operation processes W and accident A should also be considered. The corresponding parameters are operation process type g and accident type c. Therefore, formula ① is optimized to obtain the following formula:

[0076]

[0077] Thus, it can be seen from formula ② that the disposal costs under different operating processes and accidents may be different, so the disposal costs of historical standard elements in the historical operating process calculated by the formula should also be related to the operating process and accidents.

[0078] The optional step S101 includes the following sub-steps:

[0079] Sub-step 1011: obtaining each historical operation process type of the drilling project in any historical operation process.

[0080] Sub-step 1012: for any of the historical operation process types, determine the historical handling costs of each historical accident under the historical operation process type and the historical handling indicators of each historical accident.

[0081] In this step, the historical accidents in the embodiments provided in the present application include but are not limited to natural disasters or non-natural disasters including chemical poisoning, blowout, fire, electric shock, scald, chemical burn, object impact, stab, fall, bump, fall, dust, traffic accident, mechanical injury, noise, food poisoning, infectious disease, heat stroke, frostbite, flood, strong wind and earthquake.

[0082] Sub-step 1013: Determine the historical standard element disposal cost in the historical operation process according to the historical disposal cost of each of the historical accidents and the historical disposal index of each of the historical accidents.

[0083] In this step, the historical disposal indicators in the embodiments provided in this application include but are not limited to the number of personnel, disposal days, scale of property damage, disposal level of difficulty in resuming work, and daily planned income (project planned income / planned days).

[0085] S102, determining the target preset disposal cost corresponding to the target operation according to the target disposal index of each preset target accident in the current target operation process of the drilling project and the disposal cost of the historical standard element.

[0086] Here, the target preset disposal cost in the embodiment provided in the present application is used to characterize the estimated disposal cost of a preset target accident that has just occurred and has not been disposed of, and the embodiment provided in the present application matches the estimated cost through the processing process of the target operation and the type of the preset target accident, which is used as a budget reference for the disposal of the preset target accident.

[0087] In this step, it is assumed that the formula for determining the target preset disposal cost corresponding to the target job in the embodiment provided in this application is as follows:

[0088]

[0089] Here, it is assumed that g=x and c=y.

[0090] S103. Based on the target preset disposal cost, each risk feature of each preset target accident and the feature weight corresponding to each risk feature, determine the optimal risk input cost in the current target operation process, so as to achieve cost management of the risk features in the current target operation process.

[0091] In this step, the risk features in the embodiments provided in this application include but are not limited to operating personnel, management, materials, operating equipment, transport vehicles, operating areas, ground environment, and weather environment.

[0092] Among them, after determining the target preset disposal cost, the embodiment provided in the present application determines the target accident probability corresponding to all preset target accidents in the current target operation process according to each risk feature of each preset target accident and the feature weight corresponding to each risk feature, and based on the target accident probability and the target preset disposal cost, determines the optimal risk investment cost in the current target operation process, thereby providing support for the preventive safety investment in the drilling project, thereby improving the utilization rate of the enterprise's costs.

[0093] In this way, the embodiments provided in the present application can effectively conduct a controllable analysis of the direct economic losses and indirect economic losses after an accident occurs, thereby achieving cost management of the risk characteristics in the current target operation process.

[0094] The risk management method for drilling projects provided in the embodiments of the present application is compared with the drilling risk management method in the prior art. The embodiment provided in the present application determines the historical standard element disposal cost in the historical operation process through the historical disposal cost of each historical accident and the historical disposal index of each historical accident in any historical operation process of the drilling project, and determines the target preset disposal cost corresponding to the target operation according to the target disposal index and the historical standard element disposal cost of each preset target accident in the current target operation process of the drilling project, and determines the optimal risk input cost in the current target operation process according to the target preset disposal cost, each risk feature of each preset target accident and the feature weight corresponding to each risk feature, thereby realizing the cost management of all risk features of the entire drilling project in the current target operation process, which can improve the accuracy of risk management of the drilling project and greatly improve the accuracy of risk control, thereby providing more effective safety protection for the drilling project.

[0095] See also Figure 2 , Figure 2 This is a flowchart of the risk management method for drilling engineering provided in one embodiment of the present application. Figure 2 As shown in the figure, the risk management method for drilling engineering provided by the embodiment of the present application includes the following steps:

Based on the historical disposal costs of various historical accidents in any historical operation process of the drilling project and the historical disposal indicators of each of the historical accidents, determine the disposal costs of historical standard elements in the historical operation process.

[0097] S202: Determine the target preset disposal cost corresponding to the target operation according to the target disposal index of each preset target accident in the current target operation process of the drilling project and the disposal cost of the historical standard element.

[0098] S203: Determine the target accident probability corresponding to all the preset target accidents in the current target operation process according to the risk characteristics of the preset target accidents and the characteristic weights corresponding to the risk characteristics.

[0099] In this step, the formula for determining the target accident probability in the embodiment provided by this application is specifically:

[0100]

[0101] Among them, P is used to characterize the target accident probability corresponding to the preset target accident.

[0102] S204: Determine the risk input cost in the current target operation process according to the target accident probability and the target preset disposal cost.

[0103] In this step, the formula of the risk investment cost in the current target operation process in the embodiment provided by this application can be specifically:

[0104] v = p × f;

[0105]

[0106] Among them, i is used to represent the number of risk characteristics, and f is used to represent the target preset disposal cost.

[0107] S205: Determine the optimal risk input cost in the current target operation process based on the risk input cost and the preset risk prevention cost corresponding to each preset target accident.

[0108] In this step, the embodiment provided in the present application first determines the accident type of the target operation process according to the current target operation process of the drilling project, and then determines the fixed risk characteristics and volatility risk characteristics of the current target operation process according to the accident type, and then determines the optimal risk investment cost in the current target operation process based on the fixed risk investment cost corresponding to the fixed risk characteristics, the volatility risk investment cost corresponding to the volatility risk characteristics, and the preset prevention risk cost corresponding to the volatility risk characteristics in each preset target accident.

[0109] Among them, when investing in preset risk prevention costs for risk characteristics, only some risk characteristics, namely volatility risk characteristics, can be significantly affected. Assuming that the volatility risk characteristics in the embodiments provided in the present application are k1, k2 and k3, and other risk characteristics are fixed risk characteristics, the total risk investment cost in the current target operation process is determined according to the fixed risk investment cost corresponding to the fixed risk characteristics, the volatility risk investment cost corresponding to the volatility risk characteristics, the preset prevention risk cost corresponding to the volatility risk characteristics in each preset target accident, and the preset risk acceptance corresponding to each volatility risk characteristic.

[0110] In this step, the formula of the total risk investment cost in the embodiment provided in this application can be specifically:

[0111]

[0112] v=p′1(o1)k1+p′2(o1)k2+p′3(o3)k3+ds;

[0113] ⑧o1=o×r;

[0114] ⑨

[0115] Among them, ds is used to represent the fixed risk investment cost corresponding to the fixed risk characteristics; r is used to represent the preset risk acceptance corresponding to each volatility risk characteristic.

[0116] Here, since the risk characteristics cannot be completely avoided, the amount invested will approach infinity, and a preset risk acceptance r needs to be used.

[0117] Sub-step 2: determining the optimal risk input cost in the current target operation process according to the total risk input cost and a preset risk input quantity threshold.

[0118] In this step, the formula for determining the optimal risk input cost in the target operation process in the embodiment provided in this application is specifically:

[0119]

[0120] Among them, e is used to represent the optimal risk input cost.

[0121] Among them, the description of S201 to S202 can refer to the description of S101 to S102, and can achieve the same technical effect, which is not repeated here.
