多年来，抽油机井的井口连续计量都是一个行业难题，井口计量要求体积小、安装方便、无需气液分离、可在线计量油气水三相流体的气量、液量以及含水率，由于抽油机井的生产方式为连续脉动产液，因此，能够将井下泵每一冲的产液量都记录下来，将可以反映井下泵的实时工作状况(充满程度、漏失量等)，有利于开发动态、工程管理及现场管理人员详细分析抽油机井地层供液能力和井下泵及举升系统工况动态变化，及时做出调整方案。本文针对以上需求，在现有单井计量方式的研究评价基础上，建立了抽油机井多参数井口计量的创新方案，并进行了现场试验验证，获得了重大技术突破。For many years, continuous wellhead metering of pumping wells is an industry problem. Wellhead metering requires small volume, convenient installation, no gas-liquid separation, and online metering of gas volume, liquid volume and water content of oil gas water three-phase fluid. Because the production mode of pumping wells is continuous pulsating fluid production, it is possible to record the liquid production of each stroke of downhole pump, which will reflect the real-time working condition of downhole pump (filling degree, leakage, etc.), is conducive to the development performance, engineering management and on-site management personnel to analyze the formation liquid supply capacity of pumping well and the dynamic change of downhole pump and lifting system working condition, and make adjustment plan in time. Aiming at the above requirements, based on the research and evaluation of existing single well metering methods, this paper establishes an innovative scheme of multi parameter wellhead metering for pumping wells, and carries out field test verification, which has obtained a major technical breakthrough.

According to the characteristics of different stages of polymer flooding, the dynamic parameters of polymer injection in a large number of Wells are analyzed and calculated, and the production dynamic control chart is summarized and formed. In order to ensure the effect of polymer flooding, a small amount of 25 million ultra-high content polymers should be used as the plugging control slug, 19 million high-content polymers should be injected into the early plugging slug, and 7 million salt-resistant polymers should be injected in the middle and late stage. The concentration matching of classified Wells can be used to design the injection concentration of a single well. It is beneficial to optimize the amount of each injection slug and the amount of polymer of each injection slug. The establishment of the injection end optimization and adjustment chart, the production end optimization and adjustment chart, the depth profile control well selection and formation selection technical specification, the production well fracturing technical specification and other templates, formed a set of polymer flooding matching adjustment technology suitable for the development of polymer flooding, so that when to adjust, how to adjust, how to measure well selection has become the basis. The research has greatly improved the development effect of polymer flooding, and is also beneficial to the improvement of management level.

随着页岩气规模开发，滑溜水压裂液因其低黏、低摩阻、易滤失、低成本以及更适应特低渗、超低渗储层的压裂改造等特性，应用越来越广泛。滑溜水加砂可以分为段塞式和连续式两种模式。从各油气田统计数据来看，压后效果与加砂量呈一定的正相关关系，因此采用滑溜水连续加砂技术提高加砂量是必然也是最为有效的手段。通过对大型可视平板裂缝模拟系统的试验数据进行分析，掌握了滑溜水携砂规律，并进行了滑溜水连续加砂成功率影响因素分析，制作了连续加砂优化版图，确立了实施低粘滑溜水连续加砂工艺方案，同时结合现场施工经验，提出了实施连续加砂前确保成功率的预判方法。现场应用结果表明，该项加砂工艺可以实现控液提砂，提高加砂强度，在同等液量的情况下，加砂量提高100%~200%，压裂增产效果提高10%~30%。 With the large-scale development of shale gas, fracturing fluid of slick-water has been more and more widely used due to its low viscosity, low friction, easy filtration, low cost and more suitable for stimulation of ultra-low permeability and ultra-low permeability reservoirs. The model of carrying sand with slick water is divided into plug type and continuous type. To improve the quantity of sand, continuous sand with slick-water technology is inevitable, and is also the most effective means. By analyzing the test data of large visual plate crack simulation system, the author masters the law of carrying sand with slick-water, and analyzes the influencing factors of the success rate of slick-water, and establishes continuous carrying sand optimized layout, and shows the plan for continuous sand with slick-water technology, combines with experience in fracturing field, and shows the forecasting methods before continuous sand. The results of field application show that continuous carrying sand is one method of carrying sand efficiently by more sand with less liquid, under the same liquid quantity, increasing the sand quantity by 100%~200% and increasing the fracturing stimulation effect by 10%~30%.

目前国内外油气管道内检测器探头机构的设计主要采用试制的方法，所以合理的探头机构设计至关重要。本文运用有限元分析软件ANSYS Workbench建立了油气管道内检测器探头机构的有限元模型，对该模型进行了静力分析，结果表明随着探头机构压缩量的增加，支撑弹簧变形严重使探头机构姿态不稳，经试验验证，分析结果与测试结果基本一致，证明了有限元分析结果的正确性。为改善探头压缩姿态，对弹簧支撑结构进行了改进，并利用ANSYS Workbench对压缩姿态进行了分析，证明改进的探头机构具有良好的压缩姿态。 At present, the design of the detector probe mechanism in oil and gas pipelines at home and abroad mainly adopts the method of trial production, so a reasonable probe mechanism design is very important. This paper used finite element model of probe mechanism for the pipeline inspection gauge in oil and gas pipeline was established using the finite element analysis software ANSYS Workbench. Static analysis of the model was carried out. The results show that with the increase of the probe mechanism compression, the deformation of the support spring was serious which made the posture of the probe mechanism unstable. Based on the test results, correctness of the finite element analysis results was proved. In order to improve compression posture of the probe, the spring support structure was improved, and compression posture was analyzed by using ANSYS Workbench. It was proved that the improved probe mechanism had a good compression posture.

水平气井井身结构独特，油管不同下深会显著影响其泡沫排液采气措施效果。利用自主研制的水平气井气水流动实验装置，针对油管下深位置对水平气井气水流动规律及泡排效果开展了排液稳定性、携液气体流量大小、井段压力变化等特定研究。分析发现，不同油管下深会影响井筒中不同位置处的携液气体流量；当油管位于直井段及造斜位置时，能够促进实际积液水平气井实施泡排；油管深入至水平段跟端时，一定条件下存在环空辅助排液情况；油管下深超过水平段跟端时，泡排工艺并不适用。研究结果可为现场积液水平气井针对不同井段合理选用泡排技术的高效应用给予一定指导。 The wellbore structure of horizontal gas wells is unique, and different depths of tubing will significantly affect the effect of foam drainage and gas recovery measures. Based on the self-developed experimental device for gas-water flow in horizontal gas wells, the stability of liquid discharge, the flow rate of liquid-carrying gas and the change of well section pressure are studied for the gas-water flow law and foam drainage effect of horizontal gas wells at the lower depth of the tubing. It’s found that the down depth of different tubing affects the liquid carrying gas flow at different locations in the wellbore; When the tubing is located in the vertical section and the position of the deflection, it can promote the actual liquid accumulation horizontal gas well to implement bubbling; The oil pipe goes deep to the heel end of the horizontal section, and under certain conditions, there will be annulus auxiliary drainage; Once the lower depth of the tubing exceeds the heel end of the horizontal section, the soaking process will not be applicable. The results of study can give some guidance for the efficient application of rational selection of bubble drainage technology for different well sections in field horizontal gas wells with liquid accumulation.

目前常用的含水率预测方法主要包括Gompertz模型、Logistic模型和Usher模型，这三种方法缺乏理论依据，只反映了含水率与时间的统计规律，而常用的水驱规律曲线虽能反映渗流理论，但进入特高含水期后油水相对渗透率比值与含水饱和度在半对数曲线上偏离直线关系，不能用于特高含水期含水率预测。因此，本文深入研究特高含水期相渗曲线变化规律，建立了反映含水率与采出程度关系的含水率预测新模型，能够真实体现特高含水期油水地下渗流特征，预测更为准确。研究结果表明，与其他三种方法相比，含水率预测新模型预测精度提高至少3个百分点以上，为特高含水期水驱油藏开发规划制定提供了理论依据。At present, the commonly used water cut prediction methods mainly include Gompertz model, Logistic model and Usher model. These three methods lack theoretical basis and only reflect the statistical law of water cut and time. Although the commonly used water drive law curve can reflect the seepage theory, the oil-water relative permeability ratio and water saturation deviate from the linear relationship on the semi logarithmic curve after entering the extra-high water cut stage, so it cannot be used for the water cut prediction in the extra-high water cut stage. Therefore, this paper deeply studies the change law of relative permeability curve in extra-high water cut stage, and establishes a new water cut prediction model reflecting the relationship between water cut and recovery degree, which can truly reflect the characteristics of oil-water underground seepage in extra-high water cut stage, and the prediction is more accurate. The results show that compared with the other three methods, the prediction accuracy of new water cut prediction model is improved by more than 3 percent, which provides a theoretical basis for the development planning of water drive reservoir in extra-high water cut period.
