背景技术 Background technique
计量探井产出液是勘探试油工作的重点，而探井井况及地下原油物性较复杂，稠油井、含砂井、间断出液井以及高含气井等，导致探井产出液计量困难，无法准确掌握油藏状况。因此，如何控制探井产出液进行高效油气分离计量，实现探井产出液油、气、水等参数准确计量，是探井产量计量的关键，对制定生产方案具有重要的指导意义。传统的探井产出液分离采用大罐储液重力沉降、人工化验测量含水的办法，设备体积庞大，控制方法不可靠，人工取样偶然性因素大，影响探井产量计算。为此我们发明了一种新的探井计量控制装置，解决了以上技术问题。 Measuring the production fluid of exploratory wells is the focus of exploration and oil testing. However, the conditions of exploratory wells and the physical properties of underground crude oil are complex, such as heavy oil wells, sand-bearing wells, intermittent liquid-producing wells, and high-gas-bearing wells, etc., making it difficult to measure the production fluid of exploratory wells. Accurately grasp the reservoir condition. Therefore, how to control the production fluid of exploration wells for efficient oil and gas separation and measurement, and realize the accurate measurement of oil, gas, water and other parameters of production fluids of exploration wells is the key to production measurement of exploration wells, and has important guiding significance for formulating production plans. Traditional production fluid separation of exploratory wells adopts the method of gravity sedimentation of large tanks of liquid storage and manual assay to measure water content. The equipment is bulky, the control method is unreliable, and the accidental factor of manual sampling is large, which affects the production calculation of exploratory wells. For this reason, we have invented a new metering control device for exploratory wells, which solves the above technical problems.
