随着准噶尔盆地勘探开发力度的不断加大,勘探开发对象日益复杂,储层品质越发多样,呈现“低孔低渗低产”与“高温高压高产”并存,井况、工况也愈发恶劣,导致勘探开发难度与日俱增。同时受限于现场资料录取难度大,利用程度低等不利因素,经过综合效益评估,我公司结合现场经验,编制实用程序,为现场录取的试油资料进行实时分析,对储层进行快速评价,对风险进行有效识别与预防,对现场生产进行正确指导,确保试油作业安全与完井后的顺利投产。

目前准噶尔盆地南缘下组合取得历史性突破,展现了勘探的巨大潜力和光明前景。然而南缘地质条件复杂,勘探认识程度低,通过对目标区块开展技术攻关,突破瓶颈技术难题,将初步形成适应于准噶尔盆地南缘中下组合油气藏试油配套技术,为南缘大油气区建设提供支撑。

通过理论模型建立、软件编程、现场应用、完善优化等步骤,形成一套适用准噶尔盆地的试油资料动态分析技术:

油、气和水高压物性参数研究

井筒中气液两相垂直管流理论研究

油气井计算IPR(流入动态)和OPR(流出动态)曲线方法研究

油气井生产制度优化设计研究

形成油气井井筒节点分析软件并进行现场应用

我公司长期开展油气节点理论研究及软件研发工作,主要围绕每口井的地层渗流-井筒管流及油气嘴节流以及产能预测,提供从地下-节流阀-地面的一体化生产制度优化。针对常规油气藏、页岩气藏、致密气藏等地质特征和储层特点,找出制约油气井生产的因素,优化生产工艺方式及采收率,对于油气井的产能预测和优化生产工作制度,具有重要的指导意义,具有同类公司没有的巨大优势。

Products>>Project Development>>Research on key exploration well technology in Jungar basin of oil testing company in 2020

With the increasing exploration and development efforts in Jungar basin, the exploration and development objects are becoming more and more complex, the reservoir quality is becoming more and more diverse, the coexistence of "low porosity, low permeability, low production" and "high temperature, high pressure and high production" is presented, and the well conditions and working conditions are getting worse, which leads to the increasing difficulty of exploration and development. At the same time, limited by the unfavorable factors such as the difficulty of field data acquisition and low utilization degree, after comprehensive benefit evaluation, our company combined with the field experience, compiled a practical program to conduct real-time analysis for the field test data, quickly evaluate the reservoir, effectively identify and prevent the risks, correctly guide the field production, and ensure the successful production of safety oil test operation and post well completion.

At present, the lower southern margin of Jungar basin has made a historic breakthrough, showing great exploration potential and bright prospects. However, the geological conditions in the southern margin of Jungar basin are complex, and the understanding of exploration is low. Through technical research on the target block and breaking through the bottleneck technical problems, the matching technology for oil and gas reservoir testing of the middle lower combination reservoirs in the southern margin of Jungar basin will be initially formed, which will provide support for the construction of large oil and gas areas in the southern margin.

Through the steps of theoretical model establishment, software programming, field application, improvement and optimization, a set of dynamic analysis technology of well testing data suitable for Jungar basin is formed.

Study on high pressure physical parameters of oil, gas and water.

Theoretical study of gas-liquid two-phase vertical pipe flow in wellbore.

Study on calculation method of IPR (inflow performance) and OPR (outflow performance) curves for oil and gas wells.

Research on Optimization Design of oil and gas well production system.

The software for wellbore node analysis of oil and gas wells is developed and applied in the field.

Our company has long carried out the theoretical research and software development of oil and gas nodes, mainly focusing on the formation seepage, wellbore pipe flow, oil and gas nozzle throttling and productivity prediction of each well, providing the integrated production system optimization from underground to throttle valve to surface. According to the geological characteristics and reservoir characteristics of conventional oil and gas reservoirs, shale gas reservoirs and tight gas reservoirs, the factors restricting the production of oil and gas wells are found out, and the production process and recovery factor are optimized, which has important guiding significance for the productivity prediction of oil and gas wells and the optimization of production system, and has great advantages while similar companies don’t have.
