[Abstract]:In the process of oil and gas exploration and development, well testing technology is an important part of reservoir description technology, it is to accurately evaluate the oil and gas display encountered in the drilling process. The well testing technology developed in the 1930s has become an important means to recognize and evaluate the reservoir through the continuous development and perfection of the well testing technology under the development and production performance of oil and gas fields. The well testing technology developed in the 1930s has become an important means of understanding and evaluating the reservoir. With the continuous development of computer, modern well testing theory and interpretation technology put forward the application of system engineering theory to interpret and process well test data, and carry out model selection, feature judgment and internal boundary analysis in the early, middle and late stages of pressure curve. Through curve fitting, dimensionless test and curve history simulation test, the reservoir model and seepage parameters can be determined. On this basis, the reservoir productivity, boundary types and properties, hydrodynamic characteristics, damage degree and mechanism, and the dynamic characteristics of oil saturation are evaluated, and then the correct completion methods and measures are determined by these characteristics, and the dynamic reserves are calculated. In this way, reservoir performance evaluation becomes more and more accurate. This research mainly aims at the common problems existing in Jilin oilfield well testing technology to carry on the normative research and the comprehensive evaluation, on the basis of the investigation of the similar oil fields in our country, based on the petroleum and natural gas industry standard, With the software of well test interpretation as a tool, the difficulties of well testing in Jilin oilfield are emphatically solved, and the applicable well test interpretation method is studied, so as to standardize the field test and data interpretation better. It provides reliable basic parameters for the development and adjustment of oil and gas fields. In order to improve the quality of dynamic monitoring and the utilization of test data and meet the needs of reservoir engineering and geological research, the oil production plants in Jilin Oilfield should be operated from equipment, technology, interpretation and evaluation to the standard operation in order to improve the quality of dynamic monitoring and the utilization of test data. On the basis of comprehensive specification, this paper makes a comprehensive evaluation of typical oil fields, evaluates the applicability of interpretation method and evaluation method, and gives full play to the dynamic monitoring function of well testing technology. In view of the five technical problems existing in well testing and interpretation in oilfield, such as "interpretation of early data, interpretation of water well, stratification and pumping test data and determination of reasonable shut-in time", a new set of methods is studied and developed in this paper. In particular, the model study of well test interpretation of conventional horizontal wells in Jilin Oilfield is emphatically solved, and a set of applicable and effective software for well test interpretation of horizontal wells is provided, which has more advantages for low production and low permeability well Swift interpretation software. Through the analysis of an example, it is considered that the method of interpretation and the software are practical and reliable.
