Study On Analysis System Of Oil And Gas Field Exploiration Information

Oil production laws are usually needed to be generalized in order to guide oilfields'high-efficient development. In order to reach the following goals including quickening the process of oilfield's basic data collecting and processing, choosing a scientific method to predict the development index and the dynamic variation law, analyzing oil and water wells'measurement quality and effect, and thus quickening oilfield's high-speed and high-efficient development, Oilfield Development Information Analysis System is programmed. This software includes four sub-parts such as oilfield development information query and analysis, analysis of rod pumped wells'production condition and relevant equipments'working condition, and analysis of both oil and water wells'measurement quality and effect. Interconnecting with oilfield's practical condition and based on the principle of convenience, high-speed, and high-accuracy, the research on"oilfield development information query and analysis"assured the querying indexes and then the related software is made which have been tested in Henan oilfield to verify its validity and applicability. The research on"analysis of oilfield dynamic indexes and production law"ascertains the dynamic index system including recoverable reserve, final recovery efficiency, composite water cut, oil production rate, reserve recovery degree and etc. Meanwhile, after resolving methods filtering according to different dynamic analyzing, the software is programmed on the basis of the related methods'theory, characteristic, application way and application condition and field analysis is proposed in Chun 56 block in Liangjialou oilfield. The research on"analysis of rod pumped wells'production condition and relevant equipments'working condition"investigates the related effect factors and effecting degree of rod pumped well's system efficiency, pump efficiency, beam pumping unit load usage efficiency, pump checking cycle and power consuming per ton liquid, meanwhile, on the basis of multivariate quadratic non-linear regression theory and method, a computational software is made and the accuracy of regression results are verified using Henan oilfield's field data. The research on"analysis of both oil and water wells'measurement quality and effect"ascertains oil and water wells'measurement effect evaluating index system on the basis of CNPC's standard, programs computational software based on the fuzzy synthesizing judging theory which is based on analytical hierarchy process, and carries on field analysis using field's data of Xiaermen in Henan oilfield. The above research and practical analysis shows that"Oilfield Development Information Analysis System"can carry on analysis of oilfield development information scientifically, speedily and efficiently which can supply the decision maker an aiding tool.
