Research On Benefit Evaluation Of X Gas Production Plant Block In CQ Oilfield

Oil and gas are the essential driving forces for economic development,and also the important strategic materials to ensure national security and social stability.In our country,most of the onshore oil and gas fields have entered the middle and later stages of the development cycle now,so it is difficult to exploit.And the contradiction between cost and production is increasingly prominent.Based on the theory of reservoir management,the only way for the development of oil and gas enterprises is to establish the benefit evaluation system and carry out the benefit evaluation regularly.Because of entering the middle and late stage of exploitation,CQ oilfield is facing a series of problems such as inferior resources,increasing decline rate,low daily output of single well and rising cost.Therefore,it is urgent to improve the management mode and level,and establish the benefit evaluation system of oilfield block.Taking the financial data of X gas production plant from 2015 to 2020 as the starting point,this paper uses literature research method,interview method and questionnaire method to sort out the problems such as unreasonable selection of indicators and methods,disconnection between cost accounting and practice,and insufficient application of evaluation results of X gas production plant.Meanwhile,based on the theory of reservoir management and input-output,from the perspective of benefit classification evaluation and cost-benefit comparison evaluation etc,the benefit evaluation system is established and the benefit evaluation of X gas production plant is carried out.The research results show that:(1)nearly 80%of the gas wells in X gas production plant are high-profile wells,and its production and operation are both efficient and beneficial;(2)the operating cost of single well of X gas production plant is less than the output,so the pressure of decreasing cost and increasing benefit increases;(3)in natural gas wells,the benefit of horizontal wells is higher than that of directional wells,which is conducive to improving the benefit level of enterprise.(4)The proportion of little benefit wells and unproductive wells in some blocks is at a high level,and "rationalize" can reduce the cost investment of this part.At the end of the paper,the specific evaluation measures are given about the benefit evaluation concept,the system setting and the department system cooperation,so that the benefit evaluation system of X gas production plant can play a greater role.
