示功图量油技术的探索应用

Exploration and Application of Indicator Diagram Oil Measurement Technology

摘要: 齐108块地处欢喜岭油田北部，1989年投入开发，经历多次滚动部署、侧钻、调层及层系互换，目前处在蒸汽驱 + 蒸汽吞吐开发阶段。但受地质条件所限，部分油井蒸汽驱受效差存在低产低液、间出情况；油井投产时间长，进站管线老化腐蚀，合走井较多；齐108块计量多采用玻璃管量油方式，导致计量困难、误差较大。其他计量方式如单井计量器、三项计量器需要购进设备并进行工艺改造，投入较高。对比其他方式，示功图量油成本投入最低。示功图量油没有适用于齐108块的计算公式，为此设计了相关参数，现场试验准确度较高，是对玻璃管和计量器的有效补充，在齐108块具有广阔的应用前景。

Abstract: Block Qi 108 is located north of the Huanxiling oilfield. It was put into development in 1989 and has experienced rolling deployment, sidetracking, layer adjustment and layer series exchange many times. It is currently in the stage of steam drive + steam stimulation development. However, limited by geological conditions, steam flooding in some oil wells has poor effect, with low production, low liquid and intermittent production; The oil wells have been put into operation for a long time, the incoming pipelines are aging and corroded, and there are many combined wells; The measurement of Qi 108 block mostly adopts the method of measuring oil with glass tube, which leads to difficult measurement and large error. Other metering methods, such as single well metering and three-item metering, require the purchase of equipment and the transformation of processes, with high investment. Compared with other methods, the cost of indicator diagram oil measurement is the lowest. There is no calculation formula applicable to the Qi 108 block for indicator diagram oil measurement. Therefore, relevant parameters are designed. The accuracy of the field test is high, which is an effective supplement to glass tubes and meters, and has broad application prospects in Qi 108 block.
