0-1 integer programming-based oil field project group optimal deployment method

Abstract

The present invention provides a method for optimal deployment of oilfield project groups based on 0-1 integer programming. The method for optimal deployment of oilfield project groups based on 0-1 integer programming includes: step 1, determining the decision variables of the optimization model; step 2, after deployment The maximum total net present value after conversion of all projects is the optimization goal, determine the objective function; Step 3, determine the exclusion constraints of capacity projects; Step 4, determine the decision variable constraints, to avoid the possibility of re-commissioning in subsequent years after the project is put into production; Step 5 , to determine the objective practical constraints and the subjective constraints of decision makers; step 6, use the ant colony algorithm to solve the optimization model, and obtain the optimal deployment of capacity construction projects. The optimal deployment method of oilfield project groups based on 0‑1 integer programming can meet the needs of optimal deployment of production capacity construction projects, improve the scientificity and rationality of deployment of oilfield production capacity investment projects, and provide strict and reliable Methods.

Description

technical field [0001] The invention relates to the field of oil and gas field development and production capacity construction, in particular to a method for optimal deployment of oil field project groups based on 0-1 integer programming. Background technique [0002] With the deepening of development, most old oilfields in my country have entered the late stage of development, the water cut has increased, and the production has begun to decline. Limited by the material base of underground oil and gas, production decline in old oilfields is inevitable. At this time, the development and utilization of resources in new areas, strengthening the overall adjustment of old areas, and actively building capacity replacement positions play an important role in ensuring the continuous and effective development of oilfields. Continuous capacity replacement is the key to stable production in oil fields. For large oil and gas fields, there are a large number of production capacity cons...

Problems solved by technology

Although the principle of this method is clear and the operation is simple, it is not a strict optimization decision-making method in theory.

First of all, this method does not undergo rigorous mathematical calculations, and may not necessarily obtain the optimal solution; second, any decision is made under certain conditions, and simply using an economic index to filter ignores the restrictions on development behaviors caused by various realistic conditions in the oilfield ;Finally, oil field production capacity construction projects have obvious investment attributes, and the comparison of projects should fully consider the long-term interests, and arrange projects at different times for comparison
